English (GB)6.8.2 External stopThe pump can be stopped via an externalpulse, e.g. from a control room. When activating theexternal stop pulse, the pump switches from theoperational state ’Running’ into the operational state’Standby’. The corresponding symbol appears in theSignal/error display (see section 6.2.2 Operatingstates).CautionFrequent disengagement from themains voltage, e.g. via a relay, canresult in damage to the pumpelectronics and to the breakdown of thepump. The dosing accuracy is alsoreduced as a result of internal startprocedures.Do not control the pump via the mainsvoltage for dosing purposes!Only use the ’External stop’ function tostart and stop the pump!The contact type is factory-set to closing contact(=>NO). In the ’Setup > Inputs/outputs > Externalstop’ menu, the setting can be changed to openingcontact (=>NC).6.8.3 Empty and low-level signalsIn order to monitor the fill level in the tank, adual-level control unit can be connected to the pump.The pump responds to the signals as follows:7. ServiceIn order to ensure a long service life anddosing accuracy, wearing parts such asdiaphragms and valves must be regularly checkedfor signs of wear. Where necessary, replace wornparts with original spare parts made from suitablematerials.Should you have any questions, please contact yourservice partner.WarningIf the diaphragm leaks or is broken,dosing liquid will escape from thedischarge opening on the dosing head(see fig. 3).Take suitable precautions to preventharm to health and damage to propertycaused by escaping dosing liquid!Check daily whether liquid is escapingfrom the discharge opening!Fill level sensorLow levelEmptyPump status• Display is yellow• flashes• Pump continuesrunning• Display is red• flashes• Pump stopsBoth signal inputs are allocated to the closingcontact (=>NO) in the factory.
