Measure across ATS terminal lugs E1 to E2. Also check E1 to
NEUTRAL and E2 to NEUTRAL.
a. Frequency ........................................................ 60-62 Hertz
b. Terminals E1 to E2 ........................................... 240-246 VAC
c. Terminals E1 to NEUTRAL .............................. 120-123 VAC
d. Terminals E2 to NEUTRAL .............................. 120-123 VAC
8. Set the generator’s main circuit breaker (CB1) to its OFF or
OPEN position.
9. Set the AUTO/OFF/MANUAL switch to the OFF position to shut
down the generator.
NOTE:
Do NOT proceed until generator AC output voltage and frequen-
cy are correct and within stated limits. If the no-load voltage is
correct but no-load frequency is incorrect, the engine governed
speed may require adjustment. If no-load frequency is correct
but voltage is not, the voltage regulator may require adjustment.
9 .5 .10 GENERATOR TESTS UNDER
LOAD
1. Set the generator's main circuit breaker to its OFF or OPEN posi-
tion.
2. Set the UTILITY SERVICE DISCONNECT circuit breaker to the
OFF position.
3. Manually actuate the transfer switch main contacts to their
GENERATOR (STANDBY) position. Refer to "Manual Operation".
4. To start the generator, set the AUTO/OFF/ MANUAL switch to
MANUAL. When engine starts, let it stabilize for a few minutes.
5. Turn the generator's main circuit breaker to its ON or CLOSED
position. The generator now powers all LOAD circuits. Check
generator operation under load as follows:
• Turn ON electrical loads to the full rated wattage/amperage
capacity of the generator. DO NOT OVERLOAD.
• With maximum rated load applied, check voltage and fre-
quency across transfer switch terminals E1 and E2. Voltage
should be greater than 230VAC and frequency should be
greater than 59 Hertz.
• Let the generator run under rated load for at least 30 min-
utes. With unit running, listen for unusual noises, vibration,
overheating, etc., that might indicate a problem.
6. When checkout under load is complete, turn the generator's
main circuit breaker to its OFF or OPEN position.
7. Let the generator run at no-load for several minutes. Then, shut
down by setting the AUTO/OFF/MANUAL switch to its OFF posi-
tion.
8. Move the transfer switch's main contacts back to their UTILITY
position. For example, LOAD connected to UTILITY power sup-
ply. Refer to "Manual Operation". Handle and operating lever of
transfer switch should be in the UP position.
9. Turn on the utility power supply to transfer switch, using the
UTILITY SERVICE DISCONNECT circuit breaker. The utility
power source now powers the loads.
10. Set the generator's AUTO/OFF/MANUAL switch to its AUTO
position.
