If the external STOP button is not used pins 2 and 3 must be bridged.
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 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
In case of an emergency stop the +24VDC voltage on pin 4 is no
longer available.
