System failures in safety operation
If a system failure occurs one of the LEDs run1 or run2 is OFF or both flash with failure codes
(No). The LEDS can show different failure codes at the same time.
No. Description
Notes and measures
0
1) If one pocessor detects a system failure it indicates it with the
Communication
failure code and interrupts the communication with the second
failure
processor. This one signals then failure 0
2) If both LEDs remain OFF, the unit is defective and must be
repaired
5
1) The setting of the rotational switches are not identical
Setting failure
2) Switch position is invalid
6
1) left LED flashes: supply voltage is below
Under- or
the min. level < 0.85 U
N
overvoltage
2) right LED flashes: supply voltage is above
max. level > 1.15U

Input failure
A short circuit occurred on inputs
