GENERAL DESCRIPTION 4. 1. [. . . ] The control circuit isolation plug is located on the inner side of the transfer switch enclosure door. To operate manually, insert the operating handle into the square hole on the front of the mechanism and rotate to the desired position. Remove the operating handle once operation is complete and re-insert into the handle holder on the left-hand side of the transfer switch mechanism. PM062 REV 6 08/08/01 17 Thomson Technology TS 870 TRANSFER SWITCH Automatic operation may be regained by replacing the control circuit isolation plug. With all sources of power de-energized to the transfer switch, the control circuit isolation plug can be re-connected. The drive system will operate the transfer switch to the required position.

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) b) d) Utility power switching device closed and generator power switching device open; Generator power switching device closed and utility power switching device open; 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!!!!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- PM062 REV 6 08/08/01 19 Thomson Technology TS 870 TRANSFER SWITCH connected. The drive system is self-engaging and will operate the transfer switch to the required position.
