TS 870 TRANSFER SWITCH

18.TROUBLESHOOTING

DANGER!!!!

Arc Flash and Shock Hazard. Will cause severe injury or death.

Do not open equipment until ALL power sources are disconnected

This equipment must be installed and serviced only by qualified electrical personnel utilizing safe work practices and appropriate Personal Protective Equipment (PPE). Failure to do so may cause personal injury or death

Note: An optional hand held, plug-in Service Display Module (SDM) is available for the TSC 80 Transfer Controller. The SDM module provides an LCD screen to display additional detailed information on the operation and settings of the TSC 80 controller for simplified servicing/trouble shooting procedures. For detailed information, refer to the separate SDM module instruction manual (PM065).

Symptom	Possible Causes
Will not re-transfer to utility source	-	Isolation plug out
upon restoration
	- Utility disconnect switch is in the de-energized position (Service
		Entrance Rated ATS). Switch to the Energized position.
	- A test mode has been activated (check TSC 80 status LED)
	- Utility voltage is below the pre-programmed limits (check utility
		source for adequate voltage)
	- A loose control connection
	- Faulty motor limit switch
	-	Defective motor
	- TSC 80 has incorrect voltage configuration jumper setting for
		correct system voltage
	- Defective TSC 80 controller (verify output signals with circuit
		board mounted diagnostic LED’s)
	- TSC 80 has “Transfer Fail” alarm activated as indicated by
		flashing Load on Utility LED. Determine cause of alarm and
		rectify before TSC 80 is reset

Will not transfer to generator source	-	Isolation plug out
upon failure of utility source
	- Generator set not producing enough voltage/frequency or
		output circuit breaker open
	- TSC 80 has incorrect voltage configuration jumper setting for
		correct system voltage
	- Warm-up time delay function has not timed out yet (verify TSC
		80 timer setting)
	- A loose control connection
	- Faulty motor limit switch
	-	Defective motor

PERFORMANCE TEST The interconnected system shall be evaluated to ensure compliance with the appropriate schematic drawings. The proper location of sensors and power cabling shall be determined. The grounding points of the system shall be verified to determine that ground paths do not exist that would bypass the sensors. The use of high-voltage testers and resistance bridges may be required. A simulated fault current is to be generated by a coil around the sensors. The reaction of the circuit-interrupting device is to be observed for correct response. The results of the test are to be recorded on the test form provided TS 870 TRANSFER SWITCH 18.
