TS 870 TRANSFER SWITCH

9.TRANSFER SWITCH MECHANISM –1000A-1200A, T-Style

The transfer mechanism consists primarily of the transfer motor, a hub assembly, two operating rods and two power switching device operating yokes.

The reversible transfer motor drives the hub assembly, which in turn moves the operating rods that are connected to the power switching device operating yokes. The power switching device toggles are set inside the yokes and are moved by them. There are two limit switches, which are contacted by the operating yokes (one for each direction of travel), which disconnect the transfer motor power supply when the power switching devices have attained full travel. The adjuster screws, located on the yokes determine the operating point of these limit switches. Should adjustment be required, it is advisable to consult Thomson Technology for further information.

The transfer switch mechanism has three possible positions:

a)Utility power switching device closed and generator power switching device open;

b)Generator power switching device closed and utility power switching device open;

d)Both utility and generator power switching devices open, but NEVER both utility and generator power switching devices closed at the same time.

9.1.MANUAL OPERATION

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

Isolate the transfer switch from all sources of supply before opening the enclosure for manual operation. With all sources of power de-energized to the transfer switch, the control circuit isolation plug can be unplugged to prevent subsequent operation.

To operate manually, pull the release plunger and operate the handle in the desired direction.

Automatic operation may be regained by replacing the isolation plug. With all sources of power de-energized to the transfer switch, the control circuit isolation plug can be re-
