TS 870 TRANSFER SWITCH

10.RECOMMENDED MAINTENANCE

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

10.1.DO NOT perform dielectric tests on the equipment with the control components in the circuit.

10.2.Check if control components are tight in sockets.

10.3.Periodically inspect all terminals (load, line and control) for tightness. Re-torque all bolts, nuts and other hardware. Clean or replace any contact surfaces, which are dirty, corroded or pitted.

10.4.Transfer switches should be in a clean, dry and moderately warm location. If signs of moisture are present, dry and clean transfer switch. If there is corrosion, try to clean it off. If cleaning is unsuitable, replace the corroded parts. Should dust and/or debris gather on the transfer switch, brush, vacuum, or wipe clean. DO NOT blow dirt into power switching devices.

10.5.Test the transfer switch operation. While the unit is exercising, check for freedom of movement, hidden dirt, corrosion or any excessive wear on the mechanical operating parts. Ensure that the power switching device travel is correct.

10.6.Verify all program settings on the TSC 80 controller as per the TSC 80 component calibration label on the rear cover of the controller.

10.7.Transfer Mechanism 1000A-1200A-T Style ensure that the manual handle moves freely on the hub when the lock pin is disengaged. If lubrication is necessary, apply medium weight (SAE 20) oil sparingly.

10.8.Transfer Mechanism 1000A-1200A T Style -yoke pivot bearings and rod ends are permanently lubricated and do not require maintenance.

10.9.Transfer Mechanism 100A-800A S Style –lubrication of drive hub/operator arm interface. Use high viscosity moly lubricant.

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 Do not open equipment until ALL power sources are disconnected 18.
