Subfault: 61.52
Description: F-DO 01_M Overcurrent
Fault class: Output fault
Cause
Measure
Permitted output current exceeded at M output of
safe digital output F-DO 01.
– Make sure that the current consumption of the
connected load does not exceed the permitted
output current. If necessary, change the load.
– Check the external wiring of safe digital output
F‑DO 01 for crossfault.
Subfault: 61.61
Description: F-DO 00 Wire break
Fault class: Output fault
Cause
Measure
Interruption in output circuit of safe digital output
F-DO 00.
Check the external wiring at safe digital output
F‑DO 00:
– Check the load.
– Check the wiring for wire break.
– Make sure that the lowest current consumption
of the connected load does not drop below the
minimum load required for wire break detection.
Subfault: 61.62
Description: F-DO 01 Wire break
Fault class: Output fault
Cause
Measure
Interruption in output circuit of safe digital output
F-DO 01.
Check the external wiring at safe digital output
F‑DO 01:
– Check the load.
– Check the wiring for wire break.
– Make sure that the lowest current consumption
of the connected load does not drop below the
minimum load required for wire break detection.
Subfault: 61.71
Description: F-DO 00 Inductive load
Fault class: Output fault
Cause
Measure
Inductance of load connected to safe digital out-
put F-DO 00 too large, or no freewheeling diode
present.
Check the external wiring at safe digital output
F‑DO 00:
– If the load has an inductance, make sure that a
freewheeling diode is present.
– Check the freewheeling diode for proper func-
tioning.
