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. 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. 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. switch mechanism. ) (See manual operation instruction on front of transfer 7. 1. 4. 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 PM064 REV8 10/01/25 25 Thomson Technology TS 880 TRANSFER SWITCH q DO NOT perform dielectric tests on the equipment with the control components in the circuit. q q Check if control components are tight in sockets. 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. q 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. q 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. [. . . ] The engine should start following the 3-second engine start delay period and the transfer switch will begin transferring to the generator supply once the 2-second engine warm-up timer expires. Note: the engine warm-up timer will only begin timing once the generator's output rises above 90% nominal voltage and 90% nominal frequency. Once the Utility power switching device opens, the transfer switch mechanism will pause in the neutral position for the 3-second neutral delay period, then the mechanism will complete the transfer and close the generator power switching device. To determine correct operation, observe the following on the TSC 800 Controller: DISPLAY ­GEN NORMAL, Red LED above mimic bus for the generator source is On, Green LED above mimic bus for the Utility source is OFF.
