Operation

5. Manually set the transfer switch to the STANDBY position, i.e.,
load terminals connected to the generator's E1/E2 terminals.
The transfer switch operating lever should be down.
6. Set the generator's AUTO/OFF/MANUAL switch to MANUAL.
The engine should crank and start immediately.
7. Let the engine stabilize and warm up for a few minutes.
8. Set the generator's main circuit breaker to its ON (or CLOSED)
position. Loads are now powered by the standby generator.
9. Turn ON the load center of the transfer switch (T1 and T2).
10. Connect an accurate AC voltmeter and a frequency meter
across terminal lugs E1 and E2.
• Voltage should be greater than 240 volts and frequency
should be 60 Hz.
11. Let the generator run at full rated load for 20-30 minutes.
Listen for unusual noises, vibration or other indications of
abnormal operation. Check for oil leaks, evidence of overheat-
ing, etc.
12. When testing under load is complete, turn OFF electrical
loads.
13. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
14. Let the engine run at no-load for a few minutes.
15. Set the AUTO/OFF/MANUAL switch to OFF. The engine should
shut down.

CHECKING AUTOMATIC OPERATION

To check the system for proper automatic operation, proceed as
follows:
1. Set generator's main circuit breaker to its OFF (or OPEN) posi-
tion.
2. Check that the AUTO/OFF/MANUAL switch is set to OFF.
3. Turn OFF the utility power supply to the transfer switch, using
means provided (such as a utility main line circuit breaker).
4. Manually set the transfer switch to the UTILITY position, i.e.,
load terminals connected to the utility power source side.
5. Turn ON the utility power supply to the transfer switch,
using the means provided (such as a utility main line circuit
breaker).
6. Set the generator's main circuit breaker to its ON (or CLOSED)
position.
7. Set the AUTO/OFF/MANUAL switch to AUTO. The system is
now ready for automatic operation.
8. Turn OFF the utility power supply to the transfer switch.
With the AUTO/OFF/MANUAL switch at AUTO, the engine should
crank and start when the utility source power is turned OFF after a
10 second delay. After starting, the transfer switch should connect
load circuits to the standby side after a five (5) second delay. Let
the system go through its entire automatic sequence of operation.
14
With the generator running and loads powered by generator AC
output, turn ON the utility power supply to the transfer switch. The
following should occur:
• After about 15 seconds, the switch should transfer loads back
to the utility power source.
• About one minute after re-transfer, the engine should shut
down.

3.1.1 USING THE AUTO/OFF/MANUAL SWITCH
(FIGURE 3.1)
With the switch set to AUTO, the engine may

crank and start at any time without warning.
Such automatic starting occurs when utility
power source voltage droops below a preset
level or during the normal exercise cycle. To
prevent possible injury that might be caused
by such sudden starts, always set the switch
to OFF and remove the fuses before work-
ing on or around the generator or transfer
switch. Then, place a "DO NOT OPERATE"
tag on the generator panel and on the trans-
fer switch.
1. "AUTO" Position – Selecting this switch activates fully auto-
matic system operation. It also allows the unit to automati-
cally start and exercise the engine every seven days with the
setting of the exercise timer (see the Setting the Exercise
Timer section).
2. "OFF" Position – This switch position shuts down the engine.
This position also prevents automatic operation.
3. "MANUAL" Position – Set the switch to MANUAL to crank
and start the engine. Transfer to standby power will not occur
unless there is a utility failure.
