The i > 20mA symbol appears flashing on
the LCD screen plus the error message
mA exceeded' 36, and the pump stops.

'Defective metering strokes' 37, and the
pump stops.
The DIA "Diaphragm" symbol appears
flashing on the LCD screen plus the

and the pump stops.
Cause
Heavy 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 "Fault indicator" LED display lights up.
Cause
The fluid level in the storage
tank has reached "Liquid level
low 2nd stage".
The stroke tank has over‐
flowed.
The pump is in
'4 'operating mode' , a fault
behaviour has been pro‐
grammed in the
'ANALOGUE' menu and the
control current has fallen
below 4 mA.
The pump is in
'20 'operating mode' , a fault
behaviour has been pro‐
grammed in the
'ANALOGUE' menu and the
control current has risen
above 23 mA.
The metering monitor is not
correctly connected.
The metering monitor
reported too few strokes –
more than are set in the
'FLOW' menu.
The diaphragm is broken.
Remedy
Dismantle the valves and clean them - refer
to the "Repair" chapter.
Tighten the screws in the dosing head in a
diagonal pattern - refer to the "Mainte‐
nance" chapter for the tightening torque.
Replace the diaphragm - refer to the
"Repair" chapter.
If a diaphragm rupture has been indicated,
clean the diaphragm rupture indicator, refer
to the "Repair" chapter.
Wait. In the long term, arrange for Service
to update the pump software.
Connect the pump correctly to the specified
mains voltage - according to the specifica‐
tion on the nameplate.
Remedy
Top up the storage tank.
Rectify the cause, then
[P/OK] (think through
Press
the consequences for the
process!).
'Analogue'
Eliminate the cause of the
low control current or
'Analogue'
Eliminate the cause of the
high control current or
Connect the metering mon‐
itor correctly and
[P/OK] .
Press
[P/OK] .
Press
Investigate and clear the
cause
Replace the diaphragm and
check the diaphragm rup‐
ture sensor - refer to the
