Examples for wiring an analog interface:

Note:

An external voltage adjustment implicitly requires the wiring of the current control and
vice versa!

The reference voltage (+10V) or the set value voltages can be supplied by some other
sources, i.e. PLC or PC plug-in cards (0V must be connected)

The UNIT-ON command (Pins 12-6)

must

be connected implicitly.

ATTENTION!

If the unit is switched off or mains fails possibly existing output voltages or
currents will not be displayed on the monitor terminals.
