Input -
digital inputs, 8-pin connector
The controller has 8 digital user inputs. Use these inputs to connect external devices
like sensors, switches or outputs from other devices. All inputs are opto-decoupled. If
+24VDC lies on the input a logical HIGH is signalized. Not connected (e.g. switch
open) a logical LOW is signalized.
Do not short 24VDC reference potential of the controller with GND or
case ground.
Use external emergency stop:
pin 5 and 6 bridged
pin 7 and 8 bridged
The length of the connection cable for the external emergency
stop button must not more than 5m.
Use external power button:
pin 1 and 2 bridged
connect external power button (make contact) on pin 3 and 4
