Signaling faults on external I/O
Fault signaling output
Faults are signaled via relay outputs as well as via the LEDs.
In the event of a fault, the fault signaling output becomes active, contact (95-98) closes and
contact (95-96) opens. The fault signaling output resumes its original state (contact 95-98
open, contact 95-96 closed) when there are no faults and the control supply voltage is not
present.
The faults that result in pick-up of the relays are listed in the chapter "Status indicators of the
3RM1 motor starter (Page 131)".
Note
Behavior in the event of a safety-related shutdown
The fault signaling output resumes its original state in the event of a safety-related shutdown
via the control supply voltage.
Feedback output
The Standard motor starters with a control voltage of 24 V DC (3RM10..-.AA0. and 3RM12..-
.AA0.) have a feedback output (OUT Run) referred to M (A2) that outputs a high level when
the motor is in operation. Since the current flow is not monitored in the first five seconds after
switching on the device, the feedback output outputs the high level at least for this time.
The output is non-floating and can be loaded with up to one control input of a PLC. The
maximum continuous current of the output is 15 mA.
The safety-related motor starters (3RM11 Failsafe/3RM13 Failsafe) and the Standard motor
starters (3RM10/3RM12) with a control voltage of 110 to 230 V/110 V DC (3RM1...-.AA1.) do
not have a feedback output.
