10.20 Configuration of 1 st relay
RELAY CONFIG.
Run Motor
Possible selections with buttons and .
Simple Multicontr. Þ allows to start / stop a
constant speed pump
Run Motor Þ motor run indication (over the relay)
If you have selected Simple Multicontr. two parameters get new functions. The start level of the
slave pump you enter at the parameter Enable Seg. Ctl. and the stop value in the parameter
Synchron. Limit.
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.

Press for about 3 seconds to enter the
submenu and the display changes to
10.21.1 Source of the Offset input
OFFSET INPUT
Off
The second additional input can be used as required
value 2
and also for an Offset of
the 1 st required value.
There are three possibilities for the source of the OFFSET INPUT:
OFF : Offset deactivated
EXT ADC-I : Offset will be calculated according to the current input (4-20mA) at the
terminals X1/12 (X1/10=Ground).
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 (0-10V or 2-
EXT ADC-U 2-10V 10V) at terminals X1/13 (X1/10=Ground)
