5 . Features at a glance Precise and easy setting / usability and interaction The operator can easily install the pump and set it to discharge exactly the quantity of dosing liquid required for the application. In the display, the setting of the pump is read out directly, the flow is shown in ml/h, l/h, or gph. The click wheel (turn-and-push knob) and the graphical LC display with plain-text menu in more than 5 languages make commissioning and operation intuitive. As the LCD is backlit in different colours, the pump status can be seen from a distance (traffic-light concept). EN Fig. Medo GA, Medo GC, Medo GE Digital Dosing TM The SMART Digital S generation Medo GA, Medo GC and Medo GE with powerful variable-speed stepper motor brings state-of-the-art technology to perfection. Combined expert knowledge and the patented solutions set future standards. Traditional technologies such as stroke length or stroke frequency adjustment with synchronous motor or solenoid drive become a thing of the past. Unique flexibility with only a few variants The included click-stop mounting plate makes the pump more flexible. Three different positions are possible without using any additional accessories, such as wall brackets. Service and pump exchange can now be done easily and fast just by clicking the pump in and out of the mounting plate. The control cube on the Medo GA and Medo GC pump can be lifted and turned easily into three different positions: front, left or right. Fig. 4 Display Medo GA, Medo GC Thanks to a variety of operation modes, signal inputs and outputs, the pump can easily be integrated into every process. Advanced process reliability An intelligent drive and microprocessor control ensures that dosing is performed precisely and with low pulsation, even if the pump is dosing high-viscosity or degassing liquids. Malfunctions, caused e.g. by air bubbles, are detected quickly by the maintenance-free FlowControl system and then displayed in the alarm menu. The AutoFlowAdapt function automatically adjusts the pump according to the process conditions, e.g. varying backpressure. The integrated flow measurement makes additional monitoring and control equipment redundant. Fig. 3 Modularity of the control cube A turn-down ratio of up to :3000, a wide supply voltage range (00-40 V; 50/60 Hz), combined connection sets and other features reduce the models and variants to a minimum. Designed to save costs In general, the investment for a dosing pump installation is low compared to its life cycle costs including the cost of the chemicals. The following features make the SMART Digital S Medo GA, Medo GC and Medo GE pumps contribute to low life cycle costs: No underdosing or overdosing due to high dosing accuracy and FlowControl Longer maintenance intervals thanks to the universal chemical resistance of the full- diaphragm Reduced energy consumption thanks to state-of-the-art drive technology. 5

9 3. Functional description The electronically controlled variable-speed motor (stepper motor) of the Medo GA, Medo GC and Medo GE pumps provides optimum control of the stroke speed. The duration of each discharge stroke varies according to the capacity set, resulting in optimum discharge flow in any operating situation, while the duration of each suction stroke is constant (see figure below). EN The advantages are as follows: The pump always operates at full stroke length, irrespective of the capacity set; this ensures optimum accuracy, priming and suction. A capacity range of up to :3000 (turn-down ratio) reduces variants and spare parts. Smooth and continuous dosing ensuring an optimum mixing ratio at the injection point without needing static mixers. Significant reduction of pressure peaks, preventing mechanical stress on wearing parts such as diaphragm, tubes, connections, resulting in extended maintenance intervals. The installation is less affected by long suction and discharge lines. Easier dosing of high-viscosity and degassing liquids (SlowMode). The optimum dosing control shown below takes place in any operation mode.

12 3.7 Operation modes Manual control The pump ensures constant dosing according to the quantity set in l/h or ml/h or gph by means of the click wheel. The pump automatically changes between the measuring units. Analog 0/4-0 ma control Applies to Medo GA and Medo GC-AR control variant The pump ensures dosing according to an external analog signal. The dosed capacity is proportional to the input value in ma. Setting range Pump type From [l/h] Setting range* To [l/h] Medo GA Medo GA Medo GA Medo GA Medo GC Medo GC Medo GC Medo GE Medo GE * When the SlowMode function is enabled the max. flow is reduced (See page 4). Pulse control The pump doses in proportion to an external potential-free pulse signal, for example from a water meter. There is no direct relation between pulses and dosing strokes. The pump automatically calculates its optimal speed to ensure that the required quantity is dosed for each incoming pulse. Operation mode Input signal Dosing capacity ma 0 % 9.8 ma 00 % ma 0 % 9.8 ma 00 % Fig. 0 Dosing capacity Q [%] ma 0/4-0 ma control 0-0 ma Input signal [ma] Applies to Medo GA and Medo GC The quantity to be dosed is set in ml/pulse. The pump adjusts its speed according to two factors: the frequency of external pulses the set quantity per pulse. Setting range Pump type Setting range [ml/pulse] Medo GA Medo GA Medo GA Medo GA Medo GC Medo GC Medo GC The frequency of external pulses is multiplied by the set quantity. If the product exceeds the maximum flow of the pump, a maximum of 65,000 pulses can be stored for later processing with the Memory pulse function, when activated. Applies to Medo GA With the analog scaling function, the curve can be individually drawn between two arbitrary points: l/q and l/q. Fig. Dosing capacity Q [%] I ' / Q ' Analog scaling I / Q I / Q I ' / Q ' [ma] Input signal Applies to Medo GE-PR, Medo GE-P control variant The dosing quantity per pulse is adjusted with the adjustment knob according to the scale from 0. to 00 % of the stroke volume.

13 Pulse-based batch control Applies to Medo GA The set quantity is dosed in batches within the set dosing time (t). A batch is dosed every time the pump receives an external pulse. If the pump receives new pulses before a batch is completed, these pulses will be ignored. In the event of interrupts such as external stop or alarm, incoming pulses will also be ignored. After ending of the interrupts, a new batch will be dosed with the next incoming pulse. Batch volume t t Dosing timer week Applies to Medo GA The integrated real-time clock features also batch dosing based on a weekly period. There is a maximum of 6 procedures per week. Each dosing procedure consists of: Batch volume Dosing time Start time to 7 weekdays (Monday to Sunday). In case several procedures are overlapping, the procedure with the highest flow rate has the highest priority. Batch dosing is stopped during any interrupt, e.g. power supply failure or external stop, while the time continues running in the background (real-time clock). After ending of the interrupt, batch dosing proceeds according to the current status in the timeline. Pulse Pulse 0:00 Fig. Setting range Pump type Pulse-based batch control From [ml/batch] Setting range To [l/batch] Resolution [ml]* Medo GA Medo GA Medo GA Medo GA :00 :00 8:00 0: Mo Tu We Th Fr Sa Su * Due to the digital motor control, down to /8 of the dosing volume can be dosed. Fig. 4 Dosing timer week (example with 4 procedures) Dosing timer cycle Applies to Medo GA After a start delay (t) the set batch volume is repeatedly dosed in the set cycle time (t3). The dosing time (t) can be adjusted. Batch dosing is stopped during any interrupt, e.g. power supply failure or external stop while the time continues running in the background (real-time clock). After ending of the interrupt, batch dosing proceeds according to the current status in the timeline. Setting range The batch volume setting range corresponds to the pulse-based batch control setting range.

14 3.8 Functions SlowMode Applies to Medo GA, Medo GC When the SlowMode function (anti-cavitation) is selected, the pump extends and smooths its suction stroke. This results in a softer suction stroke. The SlowMode function is used in these situations: when pumping high-viscosity liquids when pumping degassing liquids when the suction line is long when the suction lift is high. Depending on the application, the motor speed during the suction stroke can be reduced individually to approximately 50 % or 5 % of the normal motor speed. The maximum pump capacity is reduced accordingly. See pages 5 and 6 for further details. External stop Applies to Medo GA, Medo GC, Medo GE-PR, Medo GE-P With the external stop function, the pump can be stopped from a remote place via an external contact. It is not recommended to switch on and off the power supply as it was usual when working with a conventional dosing pump. When working with microprocessor-controlled digital dosing pumps, the external stop signal has to be used, in order to keep the optimal dosing precision and to prevent damages to the electronics. When activating the external stop signal, the pump changes from running to standby. The operation display shows an activated external stop. The signal input can be set to normally open (default) or normally closed contact. Counters Applies to Medo GA and Medo GC The pump displays resettable and non-resettable counters in the info menu tab. Auto deaeration Applies to Medo GA The auto deaeration function avoids breakdown of the dosing process due to air-locking, when dosing degassing liquids such as sodium hypochlorite. During long dosing breaks, e.g. at the weekend or overnight, air-bubbles can form in the suction line and get into the dosing head. If too much air is in the dosing head, and the dosing process is started again, no liquid will be dosed (air-lock). Software-controlled diaphragm movements at regular intervals encourage the air bubbles to rise and finally to be displaced out of the dosing head. These movements are executed when the pump is not stopped and during dosing breaks (e.g. external stop or no incoming pulses). Calibration Applies to Medo GA and Medo GC The pump is calibrated in the factory at the nominal pressure of the respective pump type (see maximum pressure Technical data page 5, 6). After start-up, the dosing pump can be calibrated for the actual installation to ensure that the displayed value (ml, l or gph) is correct. A calibration program in the setup menu facilitates this process. The AutoFlowAdapt function keeps the dosing precision (Medo GA-FCM control variant), even if the backpressure changes. For the description of the AutoFlowAdapt function, see page 8. Counter Description Resettable Volume Accumulated dosed quantity in litres or US gallons Yes Operating hours Accumulated number of operating hours (power-on) Motor runtime Accumulated number of motor runtime hours Strokes Accumulated number of dosing strokes No Power on/off Accumulated number of times the mains supply has been switched on No Service display Applies to Medo GA, Medo GC Due to the optimised construction and the smooth digital dosing principle, the service periods are more than twice as long, if compared to conventional pumps. However, the wear parts have to be exchanged in regular intervals in order to keep the dosing precision and the process reliability at a high level. The service display in the pump shows when service of the wear parts is required. The displayed service kit product number makes service more convenient. The following information is displayed in the Info display: Display Description Service Service kit - Soon Now Reset service system 8-digit BWT product number No No No service required Order parts for service soon Service must be performed now The service kit contains all parts needed for standard maintenance: diaphragm + valves After performing the service, reset the system The following service messages appear, depending on what happens first: Display Motor runtime [h] Regular intervals [months]* Service soon 7,500 3 Service now 8,000 4 * Applies to Medo GA only In case of difficult liquids the service intervals can be shorter and service has to be performed earlier. 4

15 Level control Applies to Medo GA, Medo GC, Medo GE-PR and Medo GE-P The pump can be connected to a dual level control unit for monitoring of the chemical level in the tank. The pump can react to two level signals: Level sensors Low-level signal Empty tank signal Medo GA, Medo GC Display is yellow (Warning) is flashing Pump continues running Display is red (Alarm) is flashing Pump stops Pump reaction* Medo GE-PR, Medo GE-P LED lights up in yellow Pump continues running LED lights up in red Pump stops * Depending on the pump model and settings, the relay outputs can be activated (see Relay output, page 5) Analog output Applies to Medo GA In addition to the analog input (operation mode: analog 0/4-0 ma) the pump is also equipped with an analog 0/4-0 ma output signal. Depending on the process control requirements, the following analog output settings are available: Setting Output = Input Actual flow Backpressure Bus control Description of analog output signal Analog feedback signal (not for master-slave application). The analog input signal is mapped : to the analog output. Flow measured in the dosing head (Flow Measurement page 8) Backpressure measured in the dosing head (Pressure monitoring page 8) Set by a command in the bus communication (see below) Control variant FCM FC AR X X X X X* X* X X X X X * Output signal is calculated based on motor speed and pump status (target flow rate). Relay output Applies to Medo GA, Medo GC-AR and Medo GE-PR The pump can activate external signals by means of built-in relays switched via internal potential-free contacts. Depending on the process control requirements, the following relay output settings can be chosen: Applies to Medo GA and Medo GC-AR Signal Relay Relay Description Alarm* Alarm Display red, pump stopped (e.g. empty tank signal, etc.) Warning* Warning Display yellow, pump running (low level signal, etc.) Stroke signal Stroke signal Every completed stroke Pump dosing Pump dosing* Pump is running and dosing Pulse input Pulse input Every pulse coming in from pulse input Bus control Bus control Set by a command in the Bus communication function (page 5) (only Medo GA) Timer cycle Timer can be set in menu: on-time, cycle-time, start delay (only Medo GA) Timer week Timer can be set in menu: procedure, on-time, start time and weekdays (only Medo GA) Contact type NO* NO* Normally Open Contact NC NC Normally Closed Contact * default setting Applies to Medo GE-PR control variant Signal Description Relay Relay Alarm* Empty tank, motor blocked Low level* Low level tank Stroke signal Every completed stroke Pulse input Every pulse coming in from pulse input Contact type NO* NO* Normally Open Contact NC NC Normally Closed Contact Bus communication Applies to Medo GA The pump is equipped with a built-in module for GENIbus communication. With the additional E-Box module (please see page 36) the pump can be integrated into a fieldbus network. The bus communication possibilities enable remote monitoring and setting via the fieldbus system. Fig. 5 Medo GA with E-box Key lock and mechanical lock Applies to Medo GA, Medo GC To protect the pump from maloperation, a key lock can be set by entering a 4-digit PIN-code. When the pump is locked, it is still possible to navigate through the menus Alarm and Info and to acknowledge alarms. Two levels of protection are available: Settings: the keys and 00% are still available. Settings + keys: the keys and 00% are also locked. For temporary ( minutes) or final deactivation the preset 4-digit pin-code has to be entered again. Applies to Medo GE The adjustment knob can be locked with a locking screw to fix the current setting. * default setting 5

16 Basic settings Applies to Medo GA, Medo GC With load factory settings, the pump can be reset to the default settings. In addition, with save customer settings, the current configuration of the pump is stored and can be activated later by load customer settings. The latest saved configuration is stored in the memory. FlowControl Applies to Medo GA-FC/FCM Units Applies to Medo GA, Medo GC It is possible to select metric units (litre/millilitre/bar) or US units (US gallons/psi). Depending on the operation mode and menu, the following units are displayed: Fig. 7 Medo GA FlowControl Operation mode/function Metric units US units Manual control ml/h oder l/h gph Pulse control ml/ ml/ Analog 0/4-0 ma control ml/h or l/h gph Batch control (pulse- or timer-based) ml or l gal Calibration ml ml Volume counter l gal Pressure monitoring bar psi Additional display Applies to Medo GA, Medo GC The additional display function provides further useful status information, e.g. the target flow rate as well as the actual flow rate. The value is shown in the operation display together with the corresponding symbol. Fig. 6 Operation Manual Additional display 7.50 l/h 7.49 l/h Additional display The pump monitors the dosing process of liquids when the FlowControl function is activated. Although the pump is still operating, some influences such as air bubbles may cause reduced flow rates or even stop the dosing process. For optimal process safety and reliability, the activated FlowControl function immediately detects and displays the following malfunctions: Overpressure Discharge line burst Air bubbles in the dosing head Cavitation at the suction side Suction valve leakage Discharge valve leakage. The unique FlowControl is based on an intelligent and maintenance-free sensor integrated in the dosing head. During the dosing process, the sensor measures the actual pressure and sends the measured value to the microprocessor in the pump. An internal indicator diagram is generated combining the actual pressure value with the diaphragm position (stroke length). With it, the dosing process is monitored, as the different malfunctions can immediately be detected due to their specific deviations in the curve. Compressible air bubbles, for instance, will reduce the discharge phase and the stroke volume (see fig. 8). The sensitivity and the delay of the FlowControl function can be adjusted individually. FlowControl requires a minimum backpressure of bar. BWT recommend an additional spring-loaded valve (approx. 3 bar) on the discharge side for dosing low capacities (< l/h) (please see page 46). The following additional information can be selected: Settings Default display Description Depending on the operation mode: Actual flow (manual, pulse) ) Target flow (pulse) Input current (analog) 4) Remaining batch volume (batch, timer) 3) Time until next batch (timer) 3) Dosed volume Total dosed volume (Counters see page 3) Actual flow Actually measured flow ) Backpressure Current backpressure in the dosing head ) ) Only Medo GA-FCM control variant ) Only Medo GA-FCM/FC control variant 3) Only Medo GA pumps 4) Only Medo GA pumps and Medo GC-AR control variant 6

17 Pressure Trouble-free dosing stroke Air bubbles disturbing the dosing stroke 3 4 Stroke length Fig. 8 Indicator diagram Compression phase Discharge phase 3 Expansion phase 4 Suction phase Pressure monitoring Applies to Medo GA-FC/FCM The integrated pressure sensor measures the actual pressure of the system, which is shown in the display. A maximum pressure can be set. If the pressure in the system exceeds the set maximum (e.g. caused by a closed valve), the pressure monitoring function stops the dosing process immediately. As soon as the backpressure falls below the set maximum, the dosing process is continued. In case the pressure drops below the minimum limit (e.g. caused by a burst discharge line) the pump stops and major chemical spills are prevented. Pressure setting range Pump type Fixed min. pressure [bar]* Adjustable max. pressure [bar]** Medo GA < (default) Medo GA -0 < 3... (default) Medo GA 7-7 < (default) Medo GA 30-4 < (default) * Can be either set as a warning (pump keeps running) or as an alarm (pump stops) ** The adjustable max. pressure is equivalent to the max. operating pressure plus bar Flow measurement Applies to Medo GA-FCM The pump can precisely measure and display the actual dosing flow. Via the analog 0/4-0 ma output, the actual flow signal can easily be integrated in any process control system, without needing any additional measurement equipment. The Flow measurement function is based on an indicator diagram as described in FlowControl (page 6). Accumulating the length of each discharge stroke phase and multiplying it with the stroke frequency results in the displayed actual flow. Any malfunctions, such as air bubbles or lower backpressure, will result in a reduced or increased actual flow rate. When the AutoFlowAdapt function (page 8) is activated, the pump compensates these influences by correcting the stroke speed. AutoFlowAdapt Applies to Medo GA-FCM When activating the AutoFlowAdapt function even environmental changes will be compensated, so that the required target flow rate will be achieved. The integrated AutoFlowAdapt makes additional monitoring and control devices redundant. The AutoFlowAdapt function is based on: FlowControl: malfunctions are detected Pressure monitoring: system pressure changes are detected Flow measurement: deviations in the target flow are detected. Examples: FlowControl detects air bubbles in the system. Due to a special motor drive strategy and a certain speed increase, the pump will try to keep the flow rate constant. This is especially important when dosing degassing liquids. In general, increasing system pressure reduces the stroke volume whereas falling system pressure increases the stroke volume. The AutoFlowAdapt function compensates this by automatically and continuously adapting the motor speed. Despite fluctuating system pressure, dosing accuracy is maintained. 7

45 6.5 Multi-function valves, pressure relief valves, pressure loading valves Multi-function valves combine the functions of pressure relief valves and pressure loading valves. In addition, they allow deaeration of the pump and emptying of the outlet line for maintenance. Pressure relief valves protect the pump and the outlet-side installations against excessive pressure. All pressurised dosing installations should include a pressure relief valve. Pressure loading valves maintain a certain counterpressure for the dosing pump. They are used in the following applications: too low counterpressure or no counterpressure at all fluctuating system pressure with outlet-side pulsation damper. To prevent syphoning, when the inlet pressure is higher than the counterpressure.
