6.8.3LED Display - Power Module

Display Modes A through C

In display modes A through C, the two LEDs DM1 and DM2 of the Switch CPU are lit as described in section 6.8.2. In these three states, the status of the signaling contact and the presence of the supply voltages are displayed by the LEDs of the power module.

	F	IN1/IN5	RM	P1
			STBY	P2
	L1	IN2/IN6
			DM1
	L2	IN3/IN7
		IN4/IN8	DM2

The following table lists the significance of the three LEDs on the power module for display modes A through C:

Label	Color	Status	Meaning
F		off	The SCALANCE X414-3E has not detected
			any faults, the signaling contact is closed.
	Red	on	The SCALANCE X414-3E has detected a
			fault, the signaling contact opens.
L1		off	Power supply L1 lower than 17 V.
	Green	on	Power supply L1 higher than 17 V.
L2		off	Power supply L2 lower than 17 V.
	Green	on	Power supply L2 higher than 17 V.
