Activation and Startup
Owner’s Manual for Stationary Generators 17
During initial start up only, the generator may exceed the
normal number of start attempts and experience an “over
crank” fault. This is due to accumulated air in the fuel
system during installation. Reset the control board and
restart up to two more times, if necessary. If unit fails to
start, contact an IASD for assistance.
Check Manual Transfer Switch Operation
Refer to the manufacturer’s instructions.
(000132)
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.
Electrical Checks
Complete electrical checks as follows:
1. V
erify that the generator is OFF. A red LED on the
control panel illuminates to confirm that the system
is in the OFF mode.
2. V
erify that the Main Circuit Breaker switch on the
generator control panel is in the OFF (Open)
position.
3. T
urn OFF all circuit breakers/electrical loads that
will be powered by the generator.
4. T
urn on the utility power supply to the transfer
switch using the means provided (such as a utility
main line circuit breaker).
(000129)
DANGER
Electrocution. High voltage is present at
transfer switch and terminals. Contact with
live terminals will result in death or serious
injury.
5. Use an accurate AC voltmeter to check utility
power source voltage across transfer switch
terminals N1, N2, and N3 (if three phase). Normal
line-to-line voltage should be equivalent to rated
unit voltage.
6. Chec
k utility power source voltage across
terminals N1, N2, and N3 (if three phase) and the
transfer switch neutral lug.
7. When
certain that utility supply voltage is
compatible with transfer switch and load circuit
ratings, turn OFF the utility power supply to the
transfer switch.
8. Pr
ess MANUAL on the control panel to crank and
start the engine.
9. Allow
the engine to warm up for about five minutes.
Move the Main Circuit Breaker switch on the
generator control panel up to the ON (or closed)
position.
10. Con
nect an accurate AC frequency meter across
transfer switch terminal lugs E1, E2, and E3 (if
three phase) and verify the proper rated frequency
(50 Hz or 60 Hz).
11. Use
an accurate AC voltmeter to check generator
output voltage across transfer switch terminals E1
to E2, (E2 to E3 and E3 to E1 if three phase).
Normal line-to-line voltage should be equivalent to
site specific utility voltage.
12. Successi
vely connect the AC voltmeter test leads
across terminal lugs E1 and Neutral, then E2 and
Neutral (and E3 and Neutral if three phase). Line-
to-neutral reading in each case should match utility
voltage reading. If system is three phase, verify
that generator phase rotation matches utility phase
rotation.
13. Mo
ve the Main Circuit Breaker switch on the
generator control panel down to the OFF (Open)
position.
14. Pre
ss OFF on the control panel to shut the engine
down.
NOTE: Do
not proceed unless certain that generator AC
voltage and frequency are correct and within the stated
limits.
Test Generator Under Load
To test the generator set with electrical loads applied,
proceed as follows:
1. V
erify that the generator is OFF. A red LED on the
control panel illuminates to confirm that the system
is in the OFF mode.
2. T
urn OFF all breakers/electrical loads that will be
powered by the generator.
3. T
urn OFF the utility power supply to the transfer
switch, using the means provided (such as a utility
main line circuit breaker).
(000132)
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.
4. Manually set the transfer switch to the STANDBY
position, i.e., load terminals connected to the
generator’s E1, E2, and E3 (if three phase)
terminals.
5. Pr
ess MANUAL on the control panel. The engine
will crank and start.
6. Allow th
e engine to warm up for a few minutes.
7. Mo
ve the Main Circuit Breaker switch on the
generator control panel up to the ON (or closed)
