Indication of System Errors
These errors are indicated by flashing codes of the white LEDs Run 1
and/or Run 2. The green LEDs and all outputs turn inactive. The system
will only restart after the supply voltage has been switched off and on
again.

5)
Incorrect setting of function:
- The rotary switches for channel 1 and 2 has different or
incorrect positions
- The setting of the 4 upper Dip-switches (channel 1) are not
identically to the 4 lower Dip-switches (channel 2)

Indication of Function Errors
Function errors are indicated by the white LED Run 1 and by the output
48. During this time, the white LED Run 2 remains on. Output 58 remains
on as long as the error is pending; it flashes regularly while waiting for the
assigned start signal.
Error codes*
1) First Emergency stop contact open
2) Second Emergency stop contact open
3) Stop contact open
4) Error start input
5) Input error (interruption or short-circuit)
6) Output error at the safety output of the control unit or at the safety
outputs of the extension modules (feedback loop interrupted, assigned
output module does not exist).
7) Error at the twin contacts of the Emergency stop button
* number of short flashing impulses, followed by a longer space
In case of error 5) and 6), the LEDs Run 1 and the outputs 48 to 58 of
the inputs modules which permit activation of the safety outputs flash
fast and regularly until the error is remedied and acknowledged by a start
signal assigned to the control unit.
