4) Verify correct control wire interconnects to the engine/generator set auto start/stop circuitry. Ensure the engine controller
automatic start circuit does not draw more than 5.0 amps (resistive) across the TSC 800 Engine Start contact. The
TSC800 Engine Start contact is voltage free and the only voltage measured should result from the engine controllers
internal control logic. Note: The ATS Engine Start contact CLOSES to start the engine and OPENS to stop the engine.
5) Place the generator engine controller in the "OFF" position and open the generator local circuit breaker.
6) Ensure the ATS isolation plug is disconnected prior to application of voltage of the supply sources.
7) Energize the utility supply and the generator supply sources and verify these meet the correct voltage, phasing and phase
rotation for the ATS and system. Once these have been confirmed to be correct, de-energize both sources before installing
the isolation plug.
8) Once the isolation plug is connected, the ATS and system load may be energized with utility power once the site electrical
contractor and or owner (as required) give authorization to proceed.
9) If Utility power is within nominal limits, the ATS should transfer to the utility source. To determine correct operation, observe
the following on the TSC 800 Display: UTIL NORMAL, GEN AUTO, Green LED above mimic bus for the Utility source is
On.
10) To verify all LED’s are operational, perform a “LAMP TEST” operation (lamp test is initiated by pressing and holding the
INCREMENT & DECREMENT push buttons on the TSC 800 faceplate simultaneously On until all the LED’s
illuminate).Review TSC 800 program settings by entering the program menu. Select “Program Menu” on the display by
scrolling with the forward arrow button (right button). Select “Yes” by using the up or down arrow then enter. Password
will be displayed. Enter password “1” for read only access or password “2” for read /write access (select password 3 only
if passwords are to be changed).
11) Set the TSC 800 time clock, as there is no battery installed on the circuit board. The time clock is a 7 day, 4 week, 24
hour clock. Refer to the TSC 800 manual for time clock programming instructions. The TSC 800 time clock is used for
automatic exercise load testing.
12) TSC 800 AUTOMATIC PLANT EXERCISE PROGRAMMING (OPTIONAL): If an automatic plant exercise feature is
desired, program the TSC 800 automatic plant exercise settings. Refer to the TSC 800 manual for detailed automatic
exercise programming instructions.
13) Review the remainder of the TSC 800 program by using the enter key to navigate through the program. Verify each
program value is the same as the value, which is entered on the program data sheets. If any of these values are modified
to suit site conditions or requirements these should be noted on the data sheets for future reference.
14) UTILITY/LOAD VOLTAGE CALIBRATION: Near the end of the TSC 800 program loop are calibration menus for utility,
generator and load voltages. If TSC 800 voltage display accuracy needs to be verified, measure actual voltages on the
ATS power connections with an accurately calibrated meter. Verify that each phase-to-phase reading at the TSC 800 is
within 0.5% accuracy. Refer to the TSC 800 instruction manual for complete details on Voltage calibration if required.
Document any changes on the program data sheets. To exit the program, press and hold the exit key for a minimum of 2-
3 seconds.
15) Prior to operating the generator, ensure it is ready to be energized and the site electrical contractor and/or owner (as
required) give authorization to proceed. 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. 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.
17) With the generator operating, view the TSC 800 display and verify correct voltage is displayed. If TSC 800 generator
voltage display accuracy needs to be verified, refer to item #15 as described above.
18) To terminate the test, enter the ATS MODE MENU, select “YES” on the TSC 800 display, then selecting “NONE”, then
enter. Once initiated, the transfer switch will begin transferring to the utility supply following the 2-minute utility return
delay period. Note: the utility return delay timer will only begin timing if the utility voltage is above 90% nominal on all
phases. Once the Generator power switching device opens, the transfer switch mechanism will pause in the neutral
