5.3.1 Start and stop levels
Start and stop levels – when the unit is used with analogue level sensor you will establish the start
and stop levels corresponding to each pump.
5.3.2 Alternation, running time and break time
Alternation – You can choose for each pump to be included in the alternation cycle or to work with
its own independent start and stop level.
Max running time - To avoid that a pumps runs too long time during a pumping cycle you can limit
the time the pump is allowed to run by setting a maximum time. When it is finished the pump will stop
and the next pump in the alternation cycle start. This time is set in factory to 720 seconds.
Minimum break time - To allow a pump to cool after running you can set a min.break time before the
pump can start again. This function can seem confusing because a pump will not start when you think
it should.
Running confirmation
If running confirmation is used you know if the pump is running, if no confirmation is received the
unit will send an alarm and try to start the next pump in the alternation cycle and eventually block the
pump. This function uses the measured pump current (Current input) with the inputs I 1 to 3 activated.
Running confirmation can only be made when current transformers are used.
