11 Glossary 4. Glossary 4.1. Filtersystem Skizze Glossary Valve sequence Chamber sequence A valve offset of 2 causes: valve 1, valve 3, valve 5... are triggered A chamber offset of 1 causes: chamber 1, chamber 2, chamber 3... are cleaned. A chamber offset has higher priority than a valve offset. A chamber offset of 0 causes: all valves acc. to valce sequence in chamber 1 are pulsed. Then chamber 2 etc... Operating mode - Permanent Permanent processing of the parameterised valve sequence. Controller via start / stop signals. - dp Threshold Control of the cleaning process via the dp signal. Cleaning starts during exceeding of the parameterised upper threshold; stops when dropping below the lower threshold. - dp Controller dp signal and air flow signal v. error! text mark not defined. Influence the cleaning process. The breaks are controlled and regulated in dependence with the filter characteristics to be set via the supporting points. Online cleaning Offline cleaning Semi Compartment Offline Cleaning SCOC Post cleaning Background cleaning The dampers for pure gas and raw gas stay open during the cleaning. During the cleaning of a chamber the selected dampers of a chamber are Off. Within the chamber the valve sequence is applied. After the cleaning the chamber sequence is considered. Half-Chamber Offline Cleaning. Requires two pure gas dampers per chamber. By that way one half of the chamber can be cleaned offline, while the other half remains in the filter process. Post cleaning may be required if the complete filter has been taken out of the procedure.the post cleaning comprises of the complete filter and performs the parameterised amount of cycles / valves etc. The post cleaning uses cycletime 2. The background cleaning becomes active if no regular cleaning is performed for a parameterisable time. This is often the case in small air flows or low dust inputs. The differential pressure is reviewed regarding a minimum value at the same time. If the reading falls short it is assumed that no fan operation exists and the cleaning is discontinued. HESCH Industrie-Elektronik GmbH 11

12 Glossary Partial cycle Complete cycle Forced cleaning Drain valves Cleaning runs as long as the required start condition is present. If the start condition is missing, the cleaning will be interrupted. The cleaning then will be resumed at interruption point. If the required start condition is set, a cleaning cycle via all active valves is performed. Independently of other necessary conditions (e.g. dpthresholds) the setting of this condition starts the cleaning process. Cleaning runs as long as the condition is set, resp. in cleaning cycle until all active valves are cleaned. In connection with the operating mode partial cycle the valves can be individually processed. The control supports the drain valves at the local manifold.

General Description The system control HE 5750 is the central unit in a CAN based network of the cleaning control system for industrial hose filters. The central control communicates with the decentralised valve control units HE 5724 and the damper control units HE 5740 via the industrial CAN bus. Coordination and monitoring of all connected components and the communication with the control technology is performed by the central control. The Slavecontroller HE 5724 controls the valve control and reviewing process. Damper control units form the interface to the damper actuators. HESCH Industrie-Elektronik GmbH 13

14 Device Description 5.3. Communication Structure The central control HE 5750 is the master in the CAN bus system of the filter controller system. A PROFIBUS or a ModBus interface is alternatively available for the control technology. Altlernatively also a parallel interface for the binary signal exchange is available. However, the complete signal list can only be reached via the serial interfaces System Setup After correct installation of the unit connections among each other, setting up of the parameters must take place. For a list of the complete parameters with description please refer to chapter 5. The operating parameters can be set up via the keyboard of the central control and also via Smart Tool software. The configuration of the "Extra I/O" is possible via Smart Tool only. Parameters from the controller can be loaded, and saved, and the original project data be restored with the free version of Smart Tool.

20 Commissioning 7.4. Setting of the common baud rate in the CAN network All participants in the CAN network must have the same baud rate. Limits for the max. baud rate are set by the network extension. In general, the following rule applies: only as fast as necessary, not as fast as possible. The factory setting is 50 kbd. Master Setting: Slave Setting: Network extension: Baud rate [kbaud] Network extension [m] HESCH Industrie-Elektronik GmbH

21 Commissioning 7.6. Setting of the node no. (address) HE 5750 (Master) The address is pre-set to 43. The LSB is on the left HE 5724 (Slave) The permissible scope of adress is between 1 to 32. The address is set with the two rotary coding switches S2 and S3. In systems with one slave per filter chamber the address runs from 1 to 24. In systems with 2 slaves per chamber, the address of the first chamber is set to 1, the one of the second slave to 17. In chamber 2 of the first slave to 2, and the second slave to 18 etc. (see also possible configurations on the following pages) HE 5740 (Damper control boxes) Control units for 8 or 16 dampers are available. Units for inlet-dampers and outletdampers differ by the device addresses only. Raw gas damper units begin with address 33. Further valid addresses are 34 and 35. pure gas damper units begin with address 36. Further valid addresses are 37 and 38. For the setting, the communication card HE 5910 must be pulled out of the basic frame. There are 2 DIP switches on the circuit board. The node address is set with the 8-bit switch. The 4-bit switch influences the baud rate. The LSB is on the right side respectively Network Topology A purely serial structure is suggested. Each end of a network must be completed with 120Ω each. A respectively to be activated terminator resistor is on each CAN unit. Stub lines should be avoided. Keep unavoidable stub line as short as possible and do not complete. By keeping a purely serial topology, the network extension can possibly be increased. The used cable should be permissible for CAN bus operation. Note the diameter for more extension (>= AWG18, 0.75mm 2 )! HESCH Industrie-Elektronik GmbH 21

22 Commissioning 7.7. Local control at control cabinet The control of the filter system can locally be started or stopped. The condition of the local control is reported to the control technology. 1 = Control in operation 2 = Cleaning in process 3 = Alarm 4 = Activating local operation 5 = Start local cleaning 6= Acknowledge active alarms 7.8. Limitation of local operation The operation of the local control elements may be blocked with a parameter. Selection: >F5, >F1:parameter >interfaces >local interface Yes/No. The indicator lights function also if local operation is blocked. The operation of the keys at the control device can be limited to display only by the operator level (remote operation, remote control = On). This limitation can only be reversed via the operator level or via SmartTool. After expiry of the time Remote timeout they keyboard operation is released again, too, in case of an interruption of the connection to the controller technology. 22 HESCH Industrie-Elektronik GmbH

35 Display and operating keys 8.4. Filter time of circulation Time of circulation is the time that a complete cleaning cycle takes, for all chambers and valves. Determining the time of circulation: A cleaning cycle generally begins with chamber 1, valve 1. This is also true when this valve e.g. due to a shutdown chamber can not be controlled. At the moment of checking the valve status cycle change occurs. The counter of the cleaning cycles is also increased. Determination of time of circulation is restarted. Power failure times during a cleaning cycle will not be counted. In a power failure time of less than 4.5 days, the original start time of the cycle persists. In addition, the start time is set at the time of power recovery.this also applies when there is more than one power failure within one cycle. Note! In order to obtain determination of the time of circulation over a power failure it is necessary to set the parameter Autostart/Timeout system status up to date, so the controller continues the cycle at the point of interruption after the power recovery. Otherwise, a new cycle begins. The controller internally stores time of circulation for the last 100 cleaning cycles. The last 20 cleaning cycles can be displayed in tabular form and as a bar graph. The bar chart is accessed via the F12 key. The display in table form can be accessed via the second "System Status screen F3" (circulation). By the Process Data Pool (PDP) it is possible to transmit - the last filter time of circulation - the average of the filter time of circulation over the last 20 cycles, - and the average of the filter time of circulation over the last 3 hours (A maximum of 99 cycles) into the control system. This function can only be set via SmartTool. Simultaneously, a display will appear in the process data image of the controller. The time of circulation is formatted as a fixed-point number in minutes with one decimal place Example: Time of circulation 37 => 3.7 minutes = 3 minutes and 7 * 6 seconds = 3:42 minutes.

42 Parameter 1. System Parameters Parameter block for the description of the filter installation. Bold = factory setting 1.1. Chambers Chambers in the filter Valves / chamber valves per chamber Correct value is strictly required for immaculate functioning of the control processes Slaves / chamber Slave boxes per chamber. Each slave box controls max. 32 valves. A second slave box is required in case of more than 32 valves per chamber. Following valve assignment applies in case of two slave boxes: - even number per chamber both slaves with same number of valves - odd number per chamber 1st slave takes over (n/2 + 1) valve 1.4. Manifolds / Slave 0, 1, 2 The valve control (slave box) can switch off the air pressure of a local manifold with a switch-off valve, especially if 2 manifolds are used. With the function "valve monitoring", a slave box can monitor the pressure in two manifolds. Therefore the pressure during the valve triggering is measured. The pressure decrease during valve triggering and the pressure increase afterwards must reach certain values to avoid any valve error. The values can be adjusted with parameter 12.6 Pressure Decrease Valves in the 1st manifold Valves in one manifold. Half of the valves in two manifolds. In case two manifolds are used per slave box and distribution is odd, this parameter provides in the 1st manifold. This information is required to select the correct pressure transmitter for the valve monitoring. Without the valve monitoring function the parameter has no meaning. 42 HESCH Industrie-Elektronik GmbH

43 Parameter 1.6. Dust detectors / chamber 0, 1, 2 Dust sensors monitor the filter output, the outlet side. That can be measurement transformers with continuous output signal of 4 up to 20 ma signal, or limit switches with switch contact. The voltage supply of the sensor can be selected at the slave box. The parameter of the slave box is different for analog or switch sensors. The first slave box can evaluate two dust sensors. The dust sensors can be of different type (analog value or switch sensor). The signals are handled internally as Switched OR Isolation valves/slave 0, 1, 2 A valve control can switch two isolation valves for 2 manifolds Damper control No, Yes A damper control controls outlet dampers of up to 8 dampers. Another damper control controls the inlet dampers. By this parameter it is determined whether a damper control takes place at all. The damper control boxes transfer also some analog measuring values. The outlet node measures 3 input temperatures (display with F5) and the delta-p value. The inlet node measures also the hopper level. For more specifications on the damper control please refer to chapter 6. Damper Control Hopper level No, Yes Determines whether the system shall monitor hopper levels or not. If Yes, the master control initialises and monitors the respective digital inputs in the inlet damper control. Another parameter determines which action is performed if level high is detected. 2. Local operation Language Language 1, language 2 All texts can be displayed in two languages. The language elements are saved in a non-volatile part of the memory. The control itself operates independently from the language with internal text numbers. Each text number represents a word or a phrase. The current language set is selected by this parameter. Therefore the language set must be loaded. For the complete text list to be available it must be loaded in the controller. Switching the language is easily possible with the function keys: press the INFO key and then with the F3 key switch to the other language. Synchron time Off 0:00 23:59 A signal from the control technology sets the controller clock to the time set here. Via the serial communication or via a parallel interface the signal can be sent. HESCH Industrie-Elektronik GmbH 43

44 Parameter 3. Interfaces PLC Interface (control technology) Parallel, Profibus, Modbus, Modbus TCP The interface used between control technology (PLC) and this control. Three interfaces between control technology and master control are available. Classical Type as contact interface. The contacts are established by the modulebased in-/output system. PROFIBUS-DP as fieldbus interface. A complete image of the system is possible with profibus A modification of the parameters via profibus is not possible at present. Modbus communication via RS485. The control offers three interfaces: CAN bus is the internal bus system for the valve controls, the damper controls and the parallel interface box. PROFIBUS is the standard interface to the control technology. PROFIBUS interface is independent from the other serial interfaces. RS 232 and RS 485 form the standard interface for service and modem control. Modem interface No, Yes RS 232 is the only way for modem connection. A Hayes compatible basis control set is used for modem control. Baud rate COM1 (RS232) kbaud If the modem is selected, COM1 is automatically used with 9.6 kbaud, even if the parameter has another value. Device address Baud rate COM2 (RS485) kbaud Profibus Node-ID Modbus parity Odd, even, No/2, No/1 44 HESCH Industrie-Elektronik GmbH

45 Parameter 4. Valve Control 4.1. Operation mode Threshold, control, partial cycle Sets the Start/Stop condition of the cleaning process. Precondition: connection for the inputs Filter Start, Filter Stop etc. have been performed correctly. Permanent Start/Stop depends on the connection of the inputs. Threshold Start/Stop depends on the connection of the inputs and dpsignal (threshold is defined with special parameters) Control Control is performed according to a air flow rated dp-signal. The connection between dp-signal and air flow can be defined in a curve with 10 coordination pairs (separate parameter section 5.14) 4.2. Cleaning mode PartCycle, CleaningCyc. Setting that defines whether cleaning process with the entire cycles or with partial cycle Manuell cleaning mode Permanent, threshold, control Defines the Start/ Stop condition of the cleaning process. Permanent Start/ Stop depends only on the connection of the inputs. dp Threshold Start/Stop depends on the input connection and dp-signal (threshold is defined by special parameters) Control Regulation is performed according to an air flow-rated dpsignal. The connection between dp-signal and air flow can be defined in a curve with 10 coordination pairs (separate parameter section 14) 4.4. Valve Sequence 0 31 Additional amount for the next active valve within a chamber Chamber Sequence 0 23 Additional amount for the next active chamber First Cycletime Pulse ms Pulse time for the first set of control times. This pulse time is used for the general cleaning process First Cycletime Pause s Pause time for the first control times. This pause time is used for the general cleaning process. HESCH Industrie-Elektronik GmbH 45

46 Parameter 4.8. Second Cycletime Pulse ms Pulse time for the second set of control times. This pulse time is used for the BG Cleaning, Manual Cleaning and Post Cleaning. If 0 is entered here, the pulse Time for the first set is used Second Cycletime Pause s Pause times for the second set of control times. These pause time is used for the BG Cleaning, Manual Cleaning and Post Cleaning. If 0 is entered here, the pause time for the first set is used Pressure Switch Function No, function, blowing pressure, F+P, Time, F+T, P+T, F+P+T By using a pressure transmitter in a manifold, three functions (incl. their combinations) can be selected: Valve function After triggering a valve, the pressure must be below a certain value. If not, an error message is generated. After closing the valve, the pressure must exceed a certain value. If not, the isolation valve of the manifold is closed and an error message generated. The thresholds are defined in separate parameters. Pressure Prior to a valve being triggered, the pressure in the respective manifold must be above a certain value. If not, the valve is not triggered and an error message is generated and the value is defined by an extra parameter. Pause Time Optimisation The possibility to reduce the pause time between two valve triggerings when the pressure at the local manifold has regenerated. The pause time in the above parameters is understood as max. time that can be reduced by an early regeneration of the manifold pressure. The threshold therefore is set with parameter 12.5 Minimum Pressure in Manifold Manifold Filling Time without, s Monitoring of the pressure starts after the filling time of the manifold ends, because the manifold needs a certain time after opening the isolation valve to generate the operating pressure. If the filling time is exceeded, a Valve Does Not Close error is assumed System Pressure On No 3600,0 sec The lead time after opening the central isolation valve and further actions. 46 HESCH Industrie-Elektronik GmbH

47 Parameter System Pressure Off No 3600,0 sec Afterrunning cycle for closing the central isolation valve Drain Valves Number of drain valves per valve control box. 0 = drainage function switched off. Valves of two manifolds can be connected to one valve box. Connection sequence at the valve terminals in 2 manifolds: Blowing valves manifold1, blowing valves manifold2, drain valve manifold1, drain valve manifold Drain Pulse msec Opening period of a drain valve Drain Pause min Pause between the next activation of the same drain valve Start/Stop Function Static, dynamic The command mode from the control technology (permanent signal, sensor signal). The condition of the controller is reported back. 5. Parallel Valves 5.1. Parallel Valve/Chamber 0 1 The system can trigger 2 chambers at the same time. Each chamber that should be triggered at the same time has its own parameter. Condition: chambers to be triggered at the same time are not connected to the same valve control unit. Per cycle each chamber is triggered once only. 0 = deactivated 1 = activated Example: parallel chamber 1 with value 10: chamber 1 and chamber 10 are triggered parallel per cycle Parallel Chamber Parallel Chamber to 5.4. Parallel Chamber HESCH Industrie-Elektronik GmbH 47

48 Parameter 6. Cleaning Cycle (Cleaning Process) 6.1. Post Cleaning Cycles Post cleaning is a cleaning procedure that includes all valves of the filter system. Up to 10 repetitions of these cleaning cycles can be selected. Post cleaning is started by the post cleaning input and uses pulse and pulse time of the second cycle time set Chamber Cleaning Cycles Chamber cleaning is the cleaning of all valves in a chamber. Up to 10 repetitions of chamber cleaning can be selected Background Cleaning With very low differential pressure the background cleaning monitors the time that has passed since the last valve triggering. This is useful for the small air flow, which nevertheless generates a dust entry in the filter system. If no valve triggering took place within the background cleaning time, background cleaning with the timings of the second control timing set starts BG Cleaning Unit Valves, chamber cycles The parameter specifies what should be cleaned during the background cleaning BG Cleaning Time off, minutes Max. time between 2 valve triggerings. If the time is exceeded, the controller starts the background cleaning BG Cleaning Threshold mbar A value close to zero. If delta-p value is smaller than that, it is assumed that the system is switched off and no background cleaning takes place. 7. Chamber Control Online Offline In the online mode the chambers are cleaned with opened inlet and outlet and dampers. In the offline mode only complete chambers are cleaned. For this purpose the inlet dampers and the outlet dampers are closed prior to cleaning and then re-opened (see 7.6). 48 HESCH Industrie-Elektronik GmbH

49 Parameter 7.1. Inlet Dampers/ Chamber 0, 1, 2 Inlet dampers per chamber 7.2. Outlet Dampers/Chamber 0, 1, 2 Outlet dampers per chamber Chamber Input (level) (Function not implemented) low, high signal level for the input for chamber isolation 0 = low 1 = high 7.4. Chamber Output (level) low, high signal level for closing the dampers (outlet-/inlet dampers) 0 = low 1 = high 7.5. Damper Limit Level low, high The signal level by which the dampers report their limit level. High: the limit level of the damper is reported with high level (+24 V) Damper Offline Cleaning Raw gas, pure gas, all For the offline cleaning the damper, which is closed can be selected. This can be the inlet damper or the outlet damper, or both Semi-Offline-Cleaning No, 1, 2 1 virtual (unreal) Semi-Offline Mode 2 real Semi-Offline Mode Depending on the wiring of the isolation valves at the local pressure Manifold Damper Control Time s Max. closing time and max. opening time for monitoring the dampers. The error message Chamber Disturbance is reported if the timings are exceeded Waiting Time s During offline cleaning a waiting time can be set between the cleaning and the opening of the dampers. This delay prior to opening allows time for the dust to set. HESCH Industrie-Elektronik GmbH 49

50 Parameter Delay Time s After the opening of a damper a delay time is allowed. During this time the differential pressure, which increases by the closing of a chamber and reduces by the opening, can regenerate Abrasion Time Off, seconds Opening and closing of a damper with dust in the medium leads to abrasion. Therefore the damper on the outlet side is used for the active switch-off and switch-on of the gas flow. Switch-off: outlet damper closes, waiting time, inlet damper closes. Switch-on: inlet damper opens, waiting time, outlet damper opens Chamber Post Cleaning cycles The number of post cleanings per chamber can be selected. The parameter Chamber Offline Cleaning must be set priorly. If the conditions are fulfilled and the chamber is closed the controller sequentially triggers all valves of the chamber. The cleaning process is continued until the number of set cycles is achieved Hopper Level Monitor Switch-off, close Defines the procedure if the hopper level is high. Switch-off: no further cleaning of this chamber. Closing: no further cleaning and closing of the dampers Hopper Level Delay s Delay time between the Hopper High Signal and the action as defined in Allows time for the service staff to inspect the filter Hopper Level Rise s A delay time between the signal of the hopper level sensor and the Hopper Level High message. Allows time for the persons in charge to work off peak-loads Hopper Level Fall s Min. time required for Hopper Level High message. Both delay times regenerate the Hopper Level Hhigh message Manifold Pres. Monitor Switch-off, close Defines the procedure in case the manifold is low. Switch-off: no further cleaning of this chamber. Closing: no further cleaning and closing of the dampers Kammerabschaltung auto 0 24 Number of chambers, which can be closed automatically. Example: 6 chamber system, 1 chamber closed manually Parameter 7.18 = 3 2 chambers can be closed automatically still. 50 HESCH Industrie-Elektronik GmbH

51 Parameter Damper Jogging days The timings of the damper jogging are recorded. The damper is triggered, and reversed considerably before reaching the limit level in order not to affect the filter process. Function not yet implemented Chamber State Message Switch-off, limit level During Switch-off the cleaning state of the chamber is reported. The condition of existing dampers is reported. 8.

The current counter can be retrieved during the operating time. If the performance of the service measures is confirmed, the downcounter is re-filled with this setpoint Period Cleaning Off, hours Time for the service related to the cleaning time Period Cycles Off, cycles Time for the service related to the cleaning cycles.

52 Parameter 10. Autostart/Timeout System Start Default, actual Default causes the system to restart without history. Actual takes over the operation of the most recently saved position System Timeout Off, minutes A value to differentiate between an isolated and a short interruption of the voltage supply. Short interruption: continues the operation at the saved position. Switch-off: system restart Autostart Delay Off, minutes Delay time between switching-on and the start of the AUTO performance, which provides the operator and the control technoloy with the possibility to enter an input at the controller Remote Timeout Off, minutes The controller keys can be deactivated by the control level, per modem or PC command. After this time the controller keys are released again, in case the control level fails Local Timeout Off, minutes The local keys at the control cabinet are released again, in caes they were deactivated. 11. Passwords Access to the parameters is regulated by a system of different service levels. Everybody can see each parameter, however a password is required to modify protected parameters. After entering the password the parameters of this service level can be modified.

53 Parameter 12. Measurement Range Since the controller receives analog values only in nominated form (4 to 20mA, measurement range and physical units must be defined in order to be presented correctly Delta-P Unit mbar, mmwg 1 milli bar = mm water column 1 mm WG = milli bar Delta-P mbar 20mA correspond to the entered value Air Flow km 3 /h 1 km 3 /h =1000 m 3 /h = ltr/s = US gal/s Pressure bar The measurement range of all pressure transmitters Dust % Delta-P Filter Off s The process signal is equipped with a low-pass filter first order.

54 Parameter Minimum Pressure % Pressure in the local manifold compared to system pressure, which is mandatory for the valve triggering Pressure Drop % The pressure drop after a valve triggering is normal and is evaluated to monitor the proper operation. Positive: an absolute pressure drop related to the system pressure. Negative: a relative pressure drop related to the pressure prior to the valve triggering Lock Manifold No, yes Yes: during System Pressure Low the manifolds are locked Dust Increase % Positive values stand for the absolute dust level of the sensor. Negative values stand for the dust increase within a certain time and ignore the increasing contamination of the sensor. 0 = dust signal as switch contact Dust Monitoring Mode Act. Pulse, permanent The Dust too High message can be linked to the pulse signal to locate a destroyed filter hose. In a delay of the Dust too High signal, already another valve can have been triggered, which then leads to a wrong information. In order to avoid that, an unspecific Dust too High message can be sent with Permanent from the master control. perm; digital input dust increase = 1 % perm; analog input dust increase = % act.pulse; digital input dust increase = 0 % act.pulse; analog input dust increase = % for relative values dust increase = % for absolute values Dust Delay sec Blinds out the increased dust output on the outlet side during the cleaning and shortly afterwards Valve Current A If two valves are operated at one output, and a valve has an interruption, this will not be recognised by the malfunction monitor of the valve control. A minimum flow for 2 valves is set here, and in case of a drop this means a fault of a valve. By setting 0.1A this monitor is switched-off Odd Number of Valves 0, 1,2,3 Is only of significance if two valves per output are connected. For the power monitor not to report a valve error during an odd number of valves, the slave must be mentioned: 0: none; 1: slave1; 2: slave2; 3: slave1 and slave2 54 HESCH Industrie-Elektronik GmbH

55 Parameter Hold Function No, yes No: alarm is reversed when the cause is removed. Yes: alarm is held and requires an acknowledgement Fail-safe No, yes Logic value of alarm messages. No: high for active alarms. Yes: low for active alarms. Applies also for signal level in data communication 14. Dust Monitoring Central Dust Sensor 0 1 Function will be activated/deactivated No Yes Yes = activated No = deactivated Dust Alarm max % Global dust monitoring that runs also without valve triggering in the background. If the set value is exceeded the alarm is triggered. If dust delay is set (see chapter parameter 12.10) this is applicable here Dust Alarm relative 0 1 Setting of absolute of relative value. No Yes Yes = Absolute No = Relative Dust Pre-Alarm % If set value is exceeded an alarm is triggered Dust Main-Alarm % If the set value is exceeded the alarm is triggered. When the parameter 1.9 "Lock Dust Valve" is activated, the valves are not triggered anymore after activation of the main alarm Dust Check Time s Period of time of monitoring window Dust Alarm Filter s The period of time during which an alarm is not performed before it is reported. HESCH Industrie-Elektronik GmbH 55

56 Parameter Dust Sensor Dead Time s Reaction time of dust sensor. Constant value, which has a delay in time of the dust monitoring as consequence Lock Dust Valve 0 1 Setting valve lock after triggering the main alarm. No Yes Yes = valve is locked after triggering the main alarm. No = valve further triggered after activating the main alarm. Re-setting the alarm can remove the locking, however this applies to all valves at the same time Dust Chart Hold The time is set as to after how many seconds after triggering of the main alarm The recording at the display is stopped. No yes Yes = recording is stopped (1-200). No = recording is not stopped and continues Air Speed max m/s Air speed max. during air flow max Distance Chamber "x" Distance chamber "x" to the sensor. 15. Cleaning factors The dust distribution within the entire filter is odd. The first and the last chambers have mostly a higher dust load. A higher cleaning performance can be assigned to individual chambers (and divisions) by cleaning factors Chamber Division The cleaning with chamber division can be weighted differently within a chamber. 0 switches functioning of cleaning factors off 1 chambers are not divided 2 chambers are divided in 2 parts RF1 and RF2 apply to chamber Cleaning Factor % RF1 for chamber 1, division 1 56 HESCH Industrie-Elektronik GmbH

57 Parameter Cleaning Factor % RF2, the assignment depends on the selected chamber division Cleaning Factor % RF48, the last max. possible cleaning factor. Cleaning factors that are not required are ignored. Operation modes cleaning system: Permanent cleaning: Time-controlled cleaning Delta-p cleaning: Upper threshold started, lower threshold stopped the cleaning process. Air flow controller: Air flow-depending differential pressure control by pause time variation HESCH Industrie-Elektronik GmbH 57

58 Parameter 16. Delta-p Contr Lower threshold mbar Upper threshold mbar Delta-p Offset mbar A value that is added to the cleaning thresholds, whereby the filter effect is increased. Also set points of the filter curve are modified. Filter characteristic curve Setpoint 0% mbar recommended: bigger than 0 (e.g. 2 mbar) Setpoint 10% mbar Setpoint 20% mbar Setpoint 30% mbar Setpoint 40% mbar Setpoint 50% mbar Setpoint 60% mbar Setpoint 70% mbar Setpoint 80% mbar Setpoint 90% mbar Setpoint 100% mbar 58 HESCH Industrie-Elektronik GmbH

59 Parameter 17. Controller Parameter Setting of the pause time: To achieve a continuous cleaning, the pause time between two valve triggerings varies, depending on the current filter state. Influencing variables are either only the differential pressure or additionally also the air flow (depending on the selected settings) Maximum Pause s P-Part (proportional band) %/mbar To setting P-Part = 0 a special function is linked! The controller determines the controller deviation against the filter characteristic described by the setpoints. Yp = Maximum Pause * dx (mbar) * kp (%/mbar) Thereby the calculated pause time cannot increase more than the set Maximum Pause (17.1.) l-part (reset time) s D-Part (hold-back time) Off, s Dt-Part Off, s Proportionale Pause % Proportional factor for the pause time prolongation. The proportional factor for the pause time prolongation helps to achieve a better adjustment of the controller to the filter behaviour related to the actual air flow. In small air flows only a minimum cleaning is required, i.g. the pause prolongation is relatively high. To be able to react appropriately in low differential pressure modifications, the disproportionate considerable modifications of the pause time are required. However, to avoid controller vibrations, the modification of the pause time must take place in small step only in considerable air flows. By factory setting of 10%, the P-part during max. air flow is reduced to 10%. HESCH Industrie-Elektronik GmbH 59

60 Parameter Controller Modification % Adjustment of the controller in case of chamber isolation. The set points of the filter characteristic (14) relate to a filter, which is completely available with all chambers. It is logical that a chamber isolation is combined with a reduction of the available filter area. Thereby the area load of the remaining chambers is increasing respectively, and also the differential pressure above the filter (during same air flow and dust input). The controller algorithm in the filter control calculates the absolute air flow back to the corresponding air flow per chamber. In order to justify the increased differential pressure during made chamber isolation, the Controller Modification is used. Effect: the working point of the remaining filter is set higher by the factor Controller Modification than described by the setpoint of the filter characteristic curve (14) Controller Maximum mbar Limit value for max. Cleaning. If the differential pressure exceeds the limit value Controller Maximum, the controller is stopped and cleaned with min. pause time (= max. speed). 60 HESCH Industrie-Elektronik GmbH

82 Options 15. Options Central dust monitoring Optionally the "Central Dust Monitoring" is available. Up to 3 central dust sensors, which monitors the dust level of all chambers, are located in the clear gas duct. F 12 key: activation of the menu and toggling between two trend graphs: - Delta P graph via different time windows - Dust process graph via different time windows Info! From version 2.13 also the circulation time graphic is displayed alternately In control HE 5750, the filter is described with additional parameters to inform the control about the following: distance between chamber and sensor flue gas speed Following parameters are required: distance chamber 'x' to sensor in [m] Max. gas speed [m/s] during max. air flow Monitoring window length(s) Additonally the air flow signal must be added to the control. Info! Dust monitoring is deactivated if volume air is < 10 %. The controller calculates the current gas speed by the current air flow. Thereby the timecan be calculated, which a dust emission cloud of chamber 'x' needs to the sensor. After this time, the monitoring window length starts. If a 'Dust High' occurs, it is due to valve assigned to this monitoring window, and a respective malfunction message is generated. The controller monitors that monitoring windows do not overlap. In case of doubt, the pause is modified so that a necessary gap between two windows remains. Hinweis! The parameter table for dust monitoring can be found in chapter HESCH Industrie-Elektronik GmbH

83 Options The controll offers two trend graphs: - Dust process via different time windows - Delta P graphic via different time windows Y-axis of the monitoring graphic is dynamically scaled 1) Display of dust process (toggling via F12 key possible) 2) Measuring unit 3) Graphical display of monitoring time 4) Display duration 5) Current time 6) Via F4 key one will get back to the main 7) Chamber/valve of the right time window of the monitor 8) Right-controlled valve 9) Diagramm scaling (%/mbar) 10) Display time start 11) Number of the displayed time window 12) Present dust or delta P value 13) Display time end 14) Symbol (I) for the timing of the valve controller Time window selectable via arrow keys (to the left = earlier timing) Displayed period of time can be reduced or increased via the arrow keys; dust graphic: 18 s, 90 s, 6 min, 30 min., delta-p: 90 s, 6 min., 30 min., 2 h F1 The recording is stopped in the display, however continues running in the background F12 Toggling between dust and delta P value Info! The grafics are created by volatile data, which is saved in the memory during process time. Voltage failure leads to loss of history. HESCH Industrie-Elektronik GmbH 83
