Two and three float switch operation with one pump

Principally, following applies: When a cut-out signal is generated by either a change in level or by a

change in the float switch state, the pump does not switch off immediately, but only after the set run-

on time elapses.

8 Special

functions

8.1 AUX

inputs

Independently of the control, each pump can be switched off by an AUX input. In normal operation, the

input must be bridged. If the input is open, then the corresponding pump is stopped and an AUX1 fault

is recognized.

The function is independent of the control electronics and it affects the control circuit of

the pump directly. This function can be used in order to switch off the pump by means of a coupling

relay independently from the control or release the pump respectively.

8.2 External

Off

Should the control not be operated with float switches, the controller has the possibility to stop the

control unit using the input SW1. Both pumps switch off, when the input is closed. When the input is

The operation with three float switches and one pump does not represent a sensible mode of

operation.
