Simple Multicontr. ⇒ allows to start/stop a constant speed pump
Enable Seq.Ctl.
Synchron. Limit – this will be the stop value of the slave pump
Stop Delay fmin. – this will be the delay time before starting the slave pump.
e.g. if the speed controlled pump reaches the start level, the relay will be switched on,
and will be switched off, when the output frequency falls below the stop level.

Note:
If the incoming current signal is below 4mA, there will be an error message on
the display, but no failure is shown (failure relay is not closed). In this case the
OFFSET INPUT works like external signal=0.
EXT ADC-U 0-10V: Offset will be calculated according to the voltage input of 0-
