16 Owner’s Manual for Stationary Diesel Generators
7. Turn off utility power supply to transfer switch when
utility supply voltage is compatible with transfer
switch and load circuit ratings.
8. Press MANUAL on control panel to crank and start
engine.
9. Allow engine to warm up for approximately five
minutes. Set MLCB switch on generator control
panel to ON (CLOSED).
10. Connect an accurate AC voltmeter and a fre-
quency meter across transfer switch terminal lugs
E1, E2, and E3 (if three-phase).
11. Successively connect AC voltmeter test leads
across terminal lugs E1, E2, and E3 (if three-
phase) and neutral; then across E2 and neutral.
Voltage reading in each case should match utility
voltage reading. If system is three-phase, verify
generator phase rotation matches utility phase
rotation.
12. Set MLCB switch on generator control panel to
OFF (OPEN).
13. Press OFF on control panel to shut down engine.
IMPORTANT NOTE: Do not proceed unless genera-
tor AC voltage and frequency are correct and within
stated limits.
Test Generator Under Load
Proceed as follows to test generator with electrical loads
applied:
1. Verify generator is in OFF mode. A red LED on
control panel illuminates to verify system is off.
2. Turn off all breakers/electrical loads to be powered
by generator.
3. Turn off utility power supply to transfer switch,
using the means provided (such as a utility MLCB).
4. Manually set transfer switch to STANDBY, i.e., load
terminals connected to generator’s E1, E2, and E3
(if three-phase) terminals.
5. Press MANUAL on control panel. Engine will crank
and start.
6. Allow engine to warm up for a few minutes.
7. Set MLCB switch on generator control panel to ON
(CLOSED). The transfer switch is now powered by
standby generator.
8. Turn on circuit breaker/electrical loads powered by
generator.
9. Connect a calibrated AC voltmeter and a frequency
meter across terminal lugs E1, E2, and E3 (if three-
phase). Voltage should be approximately unit rated
voltage. Verify with clamp on amp meter to verify
unit is not overloaded.
10. Allow generator to run at full rated load for 20–30
minutes. Listen for unusual noises, vibration, or
other indications of abnormal operation. Inspect for
oil leaks, evidence of overheating, etc.
11. Turn off electrical loads when testing under load is
complete.
12. Set MLCB switch on generator control panel to
OFF (OPEN).
13. Allow engine to run at no-load for 2–5 minutes.
14. Press OFF on control panel to shut down engine. A
red LED illuminates to verify system is off.
Check Automatic Operation
Proceed as follows to check system for correct automatic
operation:
1. Verify generator is in OFF mode. A red LED on
control panel illuminates to verify system is off.
2. Install front cover of transfer switch.
3. Turn on utility power supply to transfer switch,
using the means provided (such as a utility MLCB).
NOTE: Transfer switch will transfer to UTILITY.
4. Set MLCB switch on generator control panel to ON
(CLOSED).
5. Press AUTO on control panel. The system is now
ready for automatic operation.
6. Turn off utility power supply to transfer switch.
With generator ready for automatic operation, engine will
crank and start when utility source power is turned off
after a 10 second delay (factory default setting). After
starting, transfer switch connects load circuits to standby
side. Allow system to operate through its entire automatic
sequence of operation.
With generator running and loads powered by generator
AC output, turn on utility power supply to transfer switch.
The system transfers back to utility position and then
runs through cool down cycle and shuts down.

DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.
