Connection of digital signals
Digital signals are connected via the 2 x 7-pole terminal block X5.
The levels of the digital inputs and outputs are PLC compatible.
Use relays with low-current contacts for switching the signal cables (recommendation: relays with
gold contacts).

The external voltage source supplies the digital inputs and outputs.

If the external voltage supply is also used as an alternative supply for the
control electronics (backup operation in the event of mains failure):
– For this, make the connection illustrated as a broken line.
– The external voltage source must be able to drive a current > 1 A.
This ensures that all actual values, even after mains disconnection, are still
detected and processed.
l
Connection of the external voltage source:
– Supply voltage at X5/59
– External mass at X5/39
STOP!
The voltage difference between GND2 (term. X5/39) and the PE of the controller
must not exceed 50 V.

Configuration of the internal voltage supply
l
Set a freely assignable digital output (DIGOUTx) to HIGH level.
l
For instance terminal X5/A1: Assign C0117/1 with FIXED1. 24V are thus
applied across terminal X5/A1.
Note!
Use one of the predefined configurations in C0005 for this application. With
C0005 = XX1X (e. g. 20010 for absoute positioning; limited travelling range)
FIXED1 is automatically assigned to the output X5/A1 (corresponds to 24 V at
terminal X5/A1).
