optional functions
3.1
Product description
The pump control
PS

is used for the level control of liquid
levels. The filling level is optionally determined via dynamic pressure,
bubbler system, external sensor (4 - 20 mA) or float switch. The motor
contactor directly controls two pumps with a max. output of 5.5 kW.
Furthermore, 2 relay contacts are available for the output of fault
messages. Control and configuration are extremely easy. Switching
points, times and motor current monitoring are configured using a
digital potentiometer. All values can be queried on the LC display.
LEDs indicate operational states and fault messages. There are
further keys available for the Manual - 0 - Auto functions.
