Cause
Serious crystalline deposits
on the ball seat due to the
valves drying out.
The screws in the dosing
head are too loose.
The diaphragm is not leak-
tight.
The software versions of
the pump and HMI are dif‐
ferent.
The wrong mains voltage or
no mains voltage is con‐
nected.
Red LED "Fault indicator" lights up.
Cause
The fluid level in the
storage tank has reached
"Liquid level low 2nd
stage".
MEMappears The stroke tank has over‐
flowed.
The pump is in
„Under „Analog" „operating
mode" , a fault behaviour
has been programmed in
„ANALOG" menu and
the
the control current has
fallen below 4 mA.
The pump is in
„Analog" „operating
mode" , a fault behaviour
has been programmed in
„ANALOG" menu and
the
the control current has
risen above 23 mA.
The dosing monitor is not
correctly connected.
The dosing monitor
reported too few strokes,
more than set in the
„FLOW" menu.
The diaphragm is broken.
Remedy
Dismantle the valves and clean them - refer
to the "Overhaul" chapter.
Tighten the screws in the dosing head in a
diagonal pattern - refer to the "Repairs"
chapter for tightening torque.
Replace the diaphragm - refer to the "Over‐
haul" chapter.
If a diaphragm rupture has been indicated,
clean the diaphragm rupture reporter, refer to
the "Overhaul" chapter.
Wait. In the log term, arrange for service to
update the pump software.
Connect the pump correctly to the specified
mains voltage - according to the specification
on the nameplate.
Remedy
Top up the storage tank.
Rectify the cause, then
[P/OK] key (think
press the
through the consequences
for the process!).
Eliminate the cause of the
low control current or
Eliminate the cause of the
high control current or
Connect the dosing monitor
correctly and
[P/OK] key.
Press the
[P/OK] key.
Press the
Investigate and clear the
cause
Replace the diaphragm and
clean the diaphragm rupture
sensor, refer to the "Repair"
