9.2 Description of the sockets

9.2.1 "External control" terminal

WARNING!
Unexpected startup is possible
As soon as the pump is connected to the mains, the pump
may start pumping and consequently feed chemical may
escape.
– Prevent dangerous feed chemicals from escaping.
– If you have not successfully prevented this, immediately
press the [STOP/START] key or disconnect the pump
from mains, e.g. via an emergency cu-off switch.
CAUTION!
If the pump is integrated into a system: The system must be
designed so that potential hazardous situations are avoided
by pumps starting up automatically subsequent to unin‐
tended power interruptions.
Connect the pump to the mains/power supply using the mains cable.
Should the pump be connected to the mains in parallel to inductive con‐
sumers (e.g. solenoid valves, motor), the pump must be electrically iso‐
lated when these consumers are switched off.
Supply the pumps with voltage via a contactor relay or relay using
n
separate contacts for the pump.
If this is not possible then connect a varistor (part no. 710912) or an
n
RC member, 0.22 µF / 220 Ω in parallel.

The "external control" socket is a five-pin panel jack. It is compatible with
two- and four-conductor cables.
The "Auxiliary rate" function can only be used with a five conductor cable.
