Status LED Indicators

This figure presents the status LED indicators:

1 Status LED indicators r and e: left green r, right rede

2 Status LED indicators S and E: left red S, right red E

The following tables describe the status LED indicators:

LED indicator	Color	Status	Description
r	off		Module supply not connected.
	green	single flash	reset mode
		double flash	firmware update in progress
		flashing	pre-operational state
		on	RUN state
e	off		No error detected or module supply not connected.
	red	flashing	boot loader mode
		triple flash	firmware update in progress
		on	error detected
r+e	steady red/single green flash		invalid configuration

LED indicator	Color	Status	Description
1 2 3 4	-		status of the corresponding device
	off		oWithout signal function: No error detected, all signals from female connector off ("low" state). o2-channel evaluation: No error detected, 2-channel evaluation FALSE ("low" state).
	green	on	oWithout signal function: All inputs on the female connector set ("high" state). o2-channel evaluation: 2-channel evaluation signal TRUE ("high" state)
	green	flashing	oWithout signal function: Only one input on the female connector set ("high" state). o2-channel evaluation: -
	red	on	oWithout signal function: Error detected on all inputs of the female connector. o2-channel evaluation: Error detected in 2-channel evaluation.
	red	flashing	oWithout signal function: Error detected on only 1 input of the female connector, the signal is NOT set on the second input ("low" state). o2-channel evaluation: -
	red / green	flashing	oWithout signal function: Error detected on only 1 input of the female connector, the signal is set on the second input ("high" state). o2-channel evaluation: -

LED indicator	Color	Status	Description
S E	off		RUN state or 24 Vdc supply not present
	red		boot phase or missing TM5 link or non-functioning processor (refer to safety message below)
			pre-operational state
			communication channel is not OK
			firmware for this module is a non-certified pilot version NOTE: If you observe this indication, you must immediately replace the module, or update its firmware with a certified version. In all cases, contact your Schneider Electric representative.
			boot phase, inoperable firmware
		on	Safety-related status is active.

Whenever the S and E LED indicators are illuminated continuously, this indicates that the module is inoperative. There is also a diagnostic available in the Safety Logic Controller to indicate this state. Replacement of the module must be made immediately. It is your responsibility to ensure all necessary repairs are made promptly to enable proper functionality.

WARNING

LOSS OF SAFETY FUNCTION

oImmediately replace any and all modules that indicate that they are in an inoperable state.

oEnsure that the effect on un-repaired equipment is taken into account in your risk assessment.

oMake all necessary repairs to equipment before re-starting, or continuing service of, your machine.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
