6 Operating InstructionsGeneral Inappropriate handling and use of acids and lye (storage, refilling, use/application, etc.) in the vicinity of the system invalidates any guarantee or warranty claim. Safety Instructions The safety instructions described in these instructions, existing national regulations on health protection, environmental protection and for accident prevention and any internal working, operating and safety regulations of the operator must be observed. Information that is indicated on the pump itself must be observed. Leakages of dangerous substances must be discharged in such a way that they are not harmful for people and the environment. Damage caused by electrical energy must be prevented, see the regulations of the local electricity supply company. In order to maintain the safe working condition of the pump and ensure a safe operation, the user must follow the instructions and warnings contained in this technical manual. If it must be assumed that a safe operation is no longer possible, the device must be turned off and taken out of service, and made safe against accidental operation. This is the case: - if the pump shows visible evidence of damage, - if the pump is apparently no longer in working order, - after longer periods of storage under unfavourable conditions. Before working on the pump, the pump must be disconnected from the mains. The system must be free of pressure! 1.5 Qualification and training of personnel The personnel responsible for installation, operation and service must be appropriately qualified for these tasks. Roles, responsibilities and supervision of the personnel must be clearly defined by the operator. If necessary, the staff must be appropriately trained. 1.6 Safety of the system in case of failure of the dosage pump Dosage pump design to the latest technical knowledge. Careful manufacturing process. All pumps are tested. If the pump should fail nevertheless, the security of the entire system must be ensured. Use the appropriate monitoring and control functions for this purpose. Ensure that chemicals escaping/leaking from the pump or from damaged pipes cannot cause damage to system components and buildings. It is recommended to install leakage monitors and drip pans. 6

7 Operating InstructionsGeneral 1.7 Dosing of chemicals Caution: Before switching the supply voltage on, the dosing lines must be connected in such a way, so that the chemicals present in the dosing head will not splash out and put people at risk. The dosing medium is under pressure and can cause damage to the health and the environment. Caution: When working with chemicals, the applicable regulations at the place of use are to be applied (e.g. wearing protective clothing). Observe the safety data sheets and safety regulations of the chemicals manufacturer when working with chemicals. Caution: If the diaphragm leaks or is broken, dosing liquid will escape from the discharge opening on the dosing head. Take suitable precautions to prevent harm to health and damage to property caused by escaping dosing liquid! Check daily whether liquid is escaping from the discharge opening! Replacement of the diaphragm, see chapter 7 - Service. A deaeration hose must be connected to the deaeration screw, which is led to a receptacle, such as a drip pan. The dosing medium must be in the liquid aggregate state! Observe the freezing and boiling points of the dosing medium! The resistance of parts, such as dosing head, ball valve, seals and pipes, which come into contact with the dosing medium is dependent on the medium, media temperature and operating pressure. Make sure that the parts that come in contact with the dosing medium are resistent to the dosing medium under operating conditions, see data specifications! For questions regarding the resistance of materials and suitability of the pump for specific dosing media, please contact dinotec. 7

8 Operating InstructionsGeneral description 2 General description The dinodos DDE dosage pump is a self-priming diaphragm pump. It consists of a housing with a stepper motor and electronics, as well as a dosing head with diaphragm and valves. Excellent dosing features of the pump: - Optimal suction performance (even with degassing media), because the pump is always working with full suction stroke volume. - Continuous dosing, since the medium is drawn in with a short suction stroke, regardless of the current dosing flow, and dosed with the longest possible dosing stroke. 2.1 Intended use(s) The pump is suitable for liquid, non-abrasive, non-combustible and non-flammable liquids in accordance with the instructions in these installation and operating instructions. Application areas: - Drinking water treatment - Wastewater treatment - Swimming pool water treatment - Boiler water treatment - CIP (Clean -In-Place) - Cooling water treatment - Process water treatment - Washing plants/installations - Chemical industry - Ultrafiltration processes and reverse osmosis - Irrigation - Paper and pulp industry - Food and beverage industries 2.2 Improper operating methods The operational safety of the pump is only guaranteed if it is used in accordance with section 1.4. Frequent disengagement from the mains voltage, e.g. via a relay, can result in damage to the pump electronics and to the breakdown of the pump. The dosing accuracy is also reduced as a result of internal start-ip processes. Do not use the mains voltage for control of the pump for dosing purposes. Only use the External stop function to start and stop the pump! Caution: Other types of applications or operation of pumps under ambient and operating conditions that are not allowed are considered to be improper and are not permitted. dinotec cannot be held liable for any damage resulting from incorrect use. Caution: The pump is NOT approved for operation in potentially explosive areas! Caution: A sunscreen is required for outdoor installation! 8

13 Operating InstructionsAssembly and installation 4 Assembly and installation 4.1 Pump assembly The pump is delivered with a mounting plate. The mounting plate can be mounted vertically, e.g. on a wall, or horizontally, e.g. as on a tank. It takes only a few quick steps to firmly secure the pump to the mounting plate by means of a slot mechanism. The pump can easily be released from the mounting plate for maintenance Requirements - The mounting surface must be stable and must not vibrate. - The direction of dosing should be vertically from bottom to top Align the mounting plate and install it. - Vertical installation: The mounting plate slot mechanism must be on top. - Horizontal installation: The mounting plate slot mechanism must be opposite the dosing head. - The mounting plate can be used as a drilling template; for drill hole distances, see above figure. Attaching the mounting plate Caution Take care that no cables or lines are damaged during installation! 1. Mark the drilling holes. 2. Drill the holes. 3. Secure the mounting plate with four screws (5 mm diameter), to the wall, on the mounting bracket, or on the tank Engage pump in mounting plate Attach the pump to the mounting plate support clamps and slide under slight pressure until it engages. 13

14 Operating InstructionsAssembly and installation 4.2 Hydraulic connection Caution: Danger of chemical burns! Wear protective clothing (gloves and safety glasses) while working on dosing head, on connectors or cables! The dosing head may contain water from the factory inspection. When dosing media which should not come into contact with water, another medium must be dosed beforehand! A proper function can only be guaranteed when lines supplied by dinotec are used. The used lines must correspond to the pressure limits specified in chapter 3 "Technical data". Important details regarding the installation - Observe suction lift and cable diameter, see chapter 3 "Technical data". - Shorten the hoses at right angles. - Ensure that there are no loops or kinks in the hoses. - Keep the suction lines as short as possible. - Route suction line up towards the suction valve. - Installing a filter in the suction line protects the entire installation from dirt, thus reducing the risk of leakage. How to connect the hose 1. Slide the union nut and tensioning ring on the hose. 2. Insert the cone part completely into the tube (slide in). 3. Push union nut and tensioning ring across hose. 4. Tighten the union nut by hand. Do not use any tools! When PTFE is used as sealing material, re-tighten the union nut after 2-5 hours of operation! 5. Attach the deaeration hose to the corresponding connection and lead it into a receptacle, such as a drip pan. Union nut Cone part Tensioning ring Hose Note: The pressure differential between the suction and pressure side must be at least 1 bar! Re-tighten the dosing head screws with 3 Nm before commissioning and after 2-5 hours of operation. 14

The deaeration line must be properly connected and inserted into a suitable tank. Re-tighten the dosing head screws with 3 Nm before commissioning and after 2-5 hours of operation. 5.2 Checks to be carried our before commissioning Check that the rated voltage indicated on the nameplate complies with the local conditions. Check that all connections are assembled correctly. Re-tighten connections, if necessary. Check that the dosing head screws are tightened with the specified torque (3 Nm), retighten if necessary. Check that all electrical cables and plugs are connected correctly. 5.3 Starting and deaerating the pump Connect the mains cable. Open the deaeration screw about half a turn. Press the deaeration key (100 %) and hold it down, until liquid flows out of the deaeration hose continuously and without any bubbles. Close the deaeration screw. The pump is deaerated. 17

18 Operating InstructionsOperation 6 Operation 6.1 Operating elements Logarithmic scale Capacity adjustment knob DDE Status LED "Pulse" Operating mode button Status LED "Manual" Mechanical lock Deaeration button Adjustment knob Use the capacity adjustment knob to set the dosing capacity in percent of the maximum dosing flow of the pump. Due to the logarithmical increase of the percent values, even small dosing capacities can be set accurately. Mechanical lock The mechanical lock protects the set dosing capacity against unauthorised manipulation. For locking, tighten the screw until the adjustment knob cannot be turned anymore. Keys and LEDs When pressing and holding down the deaeration key, the pump doses at 100 % for a certain time. The deaeration key can be used e.g. for deaeration. The operation mode switch is used to change between the Manual and Pulse modes (see chapter.6.2 "Operating modes"). Depending on the current mode, the respective status LED is active ("Pulse" = upper LED; "Manual" = lower LED). The status LEDs indicate the following operating states and faults: LED colour Green (flashing) Green Yellow Red Red (flashing) Operating state/error Stop Running Standby (external stop) Empty warning (alarm) Motor blocked 18

19 Operating InstructionsOperation 6.2 Operating modes The following operating modes are available: Manual, see chapter Pulse, see chapter 6.2.2) Manual In this operation mode, the pump doses constantly the dosing quantity set by the adjustment knob. The setting range is dependent on the pump type: Type Setting range [l/h] DDE DDE Pulse In this operating mode, the pump adds the set dosing quantity for each incoming (potentialfree) pulse, e.g. from a water meter. There is no direct connection between incoming pulses and dosing strokes. The pump automatically calculates the optimum stroke frequency for dosing the set volume per pulse. The calculation is based on: - the frequency of external pulses - the set stroke volume in percent The dosing quantity per pulse is set to a value between 0.1% and 100% of the stroke volume using the adjustment knob. The setting range is dependent on the pump type: Type Setting range [ml/pulse] DDE DDE The frequency of the incoming pulses is multiplied by the set dosing quantity. If the pump receives more pulses than it can process at the maximum dosing flow, it runs at the maximum stroke frequency in continuous operation. Excess pulses will be ignored. Note: To achieve the maximum dosing capacity, we recommend the following setting for dinotec measurement and control devices (also dinotecnet ready and AquaTouch), if they are set to pulse frequency: Type DDE DDE Frequency (pulses/h) at control unit Please observe our operating instructions for your measuring and control device. 19

20 Operating InstructionsOperation Changing the operating mode 1. Set the adjustment knob to 0 %. 2. Connect the mains supply (see chapter 4.3 Electrical connection). 3. Press the operating mode button and hold for at least for 5 seconds. The new operating mode is saved. 6.3 Signal inputs Note: Use force to push the connectors for signal inputs onto the connection sockets as far as they will go. Otherwise, there is no contact. The union nut cannot push the connector all the way (as far as it will go) into a contact position External stop The pump can be stopped via an external pulse, e.g. from a control center. When activating the external stop pulse, the pump switches from the operating condition "Running" to the "Standby" mode. The respective status LED lights yellow according to the selected mode. Frequent disengagement from the mains voltage, e.g. via a relay, can result in damage to the pump electronics and to the breakdown of the pump. The dosing accuracy is also reduced as a result of internal start-ip processes. Do not use the mains voltage for control of the pump for dosing purposes. To start and stop the pump, use only the "External stop" function! Empty warning To monitor the level in the tank, a one-level signal measurement (empty warning) can be connected to the pump. The pump responds to the signal in the following ways: - Active Status LED lights red - Pump stops When the tank is filled up again, the pump restarts automatically! Changing the contact type The signal inputs (empty warning and external stop) are configured at the factory as normally open contact (NO). They can be reconfigured as normally closed contact (NC). The reconfiguration is always made for both inputs. 1. Set the adjustment knob to 0 %. 2. Connect the mains supply 3. (see chapter 4.3 Electrical connection). 4. Press the deaeration button and the operation mode button simultaneously and hold for at least 2 seconds, The new contact type is saved. 20
