TRANSFER SWITCH MECHANISM ­ 1000A- 1600 AMP (T STYLE) 9. 1. [. . . ] An engine cooldown timer circuit will be initiated once the load is transferred from the generator supply. Following expiry of the cooldown delay period (adjustable from 0 to 30 min. ), the engine start signal will be removed (contact opening) to initiate stopping of the generator set. Note: For transfer switches with MEC 2/20, MEC 310 controllers, engine start signal is internal to the controller. PM059 REV 6 08/05/05 8 Thomson Technology TS 830 TRANSFER SWITCH 5. 1. 2. OVER CURRENT TRIP (TSC 80/TSC 800 CONTROLLERS) Should the utility power switching device trip open due to an over current condition, TSC 80 or TSC 800 transfer controller will initiate an engine start signal and will permit transfer of the load to the generator supply. The utility source will be locked out and the load will remain on the generator supply until the TSC 80/TSC 800 alarm signal is manually reset. Refer to the TSC 80 & TSC 800 Instruction Manuals for further details on Transfer Fail operation. Should the generator power switching device trip open due to an over current condition, TSC 80/TSC 800 transfer controller will initiate transfer of the load to the utility supply. The generator source will be locked out and the load will remain on the utility supply until the TSC 80/TSC 800 alarm signal is manually reset. 5. 1. 3. OVER CURRENT TRIP (MEC 2/MEC 20/MEC 310 CONTROLLERS) Should the utility power switching device trip open due to an overcurrent condition, the generator will not automatically start and transfer on load. Should the generator power switching device trip open due to an overcurrent condition, the generator will shutdown and the load will automatically return to the utility supply if its voltage is normal. Note: for automatic transfer to utility, the transfer switch must be factory ordered with a "gen breaker tripped" auxiliary contact inside the generator power switching device and must be wired to the gen set controllers shutdown alarm circuits. Refer to the Gen Set controller instruction manual for further details on manual operation or shutdown-reset operation. 5. 2. TEST MODES The transfer switch may be tested utilizing the controller pushbuttons or optional test switch. A simulated utility power failure condition will be activated when the test mode is selected. The transfer switch will operate as per a normal utility power fail condition. The transfer switch will remain on generator supply until the test mode is terminated. It will then immediately transfer back to the utility supply and then continue to operate the PM059 REV 6 08/05/05 9 Thomson Technology TS 830 TRANSFER SWITCH generator set for its cooldown period then stop. Note: The transfer switch will automatically return to the utility supply (if within nominal limits) if the generator set fails while in the test mode. 6. OVER CURRENT PROTECTION Thomson Technology TS 830 series of Automatic Transfer Switches are supplied standard with integral over current protection. The type of over current protection utilized is dependent upon ATS amperage size and optional features specified. For transfer switches rated 100A through 800A, over current protection is nonadjustable thermal-magnetic type trip units. For transfer switches rated 1000A through 1600A over current protection is adjustable electronic type with long time & instantaneous trip unit elements with optional ground fault protection elements. Note: For models of transfer switch with adjustable integral over current protection trip units, the over current protection must be set prior to operation. The equipment will be shipped from the factory with a long-time current setting of 100% (of the equipment rating) and maximum instantaneous/short-time/ground fault (if supplied) current and time delay settings. Do Not Energize this equipment until device settings have been verified to ensure proper system protection & coordination. [. . . ] While the unit is exercising, check for freedom of movement, hidden dirt, corrosion or any excessive wear on the mechanical operating parts. Verify all program settings on the controller as per the calibration label or programming sheets. Transfer Mechanism 100-800A HS Style ­lubrication of drive hub/operator arm interface.
