F 3	Conv.fan curr.fault	Current converter fan not within limits	11103 bit 11	(1)

	The current of the converter´s cooling fan is
	measured via the option board PW1002/3.	S21.232
	Check: - Fan supply, fan current;	S21.232
	- Setting of PW1002,	and
	- Setting of PW1002,	higher
	SET_MAX_BR_TEMP [P519] and	higher
	SET_MAX_BR_TEMP [P519] and
	CONV_TEMP_DELAY [P527]

-Direction of rotation, fan compo nents, air inlet

F 4 Converter overtemp. Overtemperature power section

11101 bit 3

(2)

Check: - Fan supply, direction of rotation, fan components, air inlet and ambient temperature;

- Inadmissible load cycle?

F 5

Earth fault

Earth fault (Σ I differs from zero)

11101 bit 4

(1)

Disconnect the mains and verify zero voltage in armature and field circuits.

Make insulation test for the complete installation.

Check sum current transformer; if necessary, change transformer and SDCS-IOB-3 board.

F 6 Motor 1 overtemp.

Overtemperature of MOTOR 1

11101 bit 5 (2)

Check: - Temperature sensor and its cabling;

-Motor cooling or sizing;

-Inputs for temperature sensor on board SDCS-IOB-3;

-Parameter setting MOT1.TEMP_

FAULT_L [P 1403] correct?

Note: It will only be possible to reset this fault signal when the motor temperature has fallen below the threshold which is valid for the ⇒ alarm signal A 103; the signal will also be evaluated while the mains contactor is de-energized (open).

F 7 Motor 1 overload	Overload of MOTOR 1 (Thermal model 1)	11101 bit 6	(2)
	Check: - Motor temperature (let motor cool
	down and restart);

-Motor ratings and parameters of thermal model;

-Motor sizing or load cycle.
