Prior to repair and maintenance work and metering of dangerous media, always rinse the
metering head, relieve the pressure pipe and wear protective clothing (protective goggles,
gloves and apron).
When opening the covers or removing parts, except when this is possible without tools,
voltage-carrying parts may be exposed. Connection points may also be under live
voltages.
Possible cause
Incorrect voltage
Depositions, sticking, vaves
dried out
Metering head loose
Diaphragm ruptured
Standby signal
Lack of chemicals
Jumper loose
Metering lock active
Connector system Connection II
no contact
Float jammed
Suction lance connector or
jumper loose or not connected
Suction lance cable defective
Valve on recipro-cating pump
unit leaking
Metering rate setting too low
Metering valve blocked
Metering counterpressure too
high
Output 5 V on Cable Socket II
overloaded
Possible cause
Metering system jammed
Metering without request
Mains cable damaged
Remedy
Check mains voltage
Flush metering head via suction line, if necessary
remove valves and clean or replace
Tighten metering head fixing bolts crosswise and
diagonally
Replace diaphragm
Stock product
Top up storage tank
Check whether jumper has been positions
Fit jumper to Connection II
Cancel metering lock as per connecting diagram
Check contact of connector system Connector II
Free float
Tighten connector, clean contacts
Check whether jumper has been positioned
Replace empty signal system
Clean valve, replace valve spring
Increase stroke quantity adjustment
Clean and rinse valve
Check metering line and return line
Once the cause of the problem has been
eliminated, the mains must be switched off or the
master switch set to "0" in order to cancel and
acknowledge the fault signal
Limit max. load to 80 mA
