[. . . ] Electrical conductors are adequately secured away from moving parts. To maintain operational integrity, ensure that: q q All control devices are in good condition and correctly calibrated. All control devices are adequately secured in their plug-in fixtures. Failure to correctly maintain an automatic transfer switch may present a hazard to life and equipment. Full operational testing must be done prior to placing a transfer switch in service subsequent to any maintenance or repair. Any service work involving electrical components requires high-potential testing to ensure that 7. 1. 3. MANUAL OPERATION DANGER!!!! PM064 REV8 10/01/25 24 Thomson Technology TS 880 TRANSFER SWITCH Arc Flash and Shock Hazard. 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.

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. 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. 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. Ø Verify all program settings on the TSC 800 controller are as per the programming sheet supplied with the transfer switch. [. . . ] In preparation for operation, turn the generator's engine control switch to the "Automatic" start position. 16) To transfer the generator on load, perform a load test by entering the ATS MODE MENU, selecting "YES" on the TSC 800 display, then selecting "ON LOAD" test, then enter. 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. [. . . ]
