INITIAL START UP
*************
***** WARNING *****
*************
EQUIPMENT DAMAGE - DO NOT jump start these engine
generator sets. Starting these units on a low battery or jump
starting them will cause damage to the engine control module.
Use the following check list to verify correct installation before
starting the engine:
1. Engine oil. Fill as required with proper grade/qty.
2. Engine coolant. Fill as required with proper
mixture.
3. Unit mounting base properly bolted down.
4. Clearance for service and maintenance on all
sides.
5. Proper fuel line material and size.
6. All fuel line connections tight.
7. Fuel line protected and a moisture trap installed
(may be required for N.G.).
8. Correct LP/NG pressure 4-6 Oz. (7-11" Wc).
9. Battery connections clean and tight.
10. Battery fully charged.
11. All AC and DC wiring installed and properly
protected.
After completing the above checklist, the engine-generator
set is ready for the initial start-up test.
PROCEDURE
Depress the “RUN” push-button on the front of the DGC. The
engine-generator will crank and start automatically. If the engine
fails to start, depress the “stop” push-button and correct the
trouble before proceeding.
With the engine running smoothly check the no load voltage and
frequency on the digital display. The voltage should be 208/240/
480 AC depending on which model you have and a frequency of
59.5 To 60.5 hertz (Hz).
If you have the proper voltage at the generator the next step is to
check the voltage at the generator terminals in the Automatic
Transfer Switch. The voltage between the G1 and the G3
terminals should be the same as it was on the generator front
panel. The voltage should also be checked between the hot
terminals (G1 and G3) and the G-N to be certain of a balanced
voltage output and a solid neutral connection. The voltage
between G1 and G-N should be about 120 volts AC (277 on 480
units). The same approximate voltage should be found between
terminals G3 and G-N (120 volts AC).
On three phase panels the G2 voltage level should also be
checked. ON 240 VOLT (DELTA) SYSTEMS BE SURE YOU
KNOW WHERE THE HIGH VOLTAGE "WILD" LEG IS. IT
MUST BE IN THE SAME LOCATION ON THE LINE SIDE AS IT
IS ON THE GENERATOR SIDE. (i.e. if it's on L-3 on the line side
it must be on G-3 on the generator side.
** Notice **
If for any reason during the check out procedure the voltage and
frequency are not correct, depress the “OFF” push-button and
correct the trouble before proceeding.
After verifying that the voltage and frequency are correct, depress
the “OFF” push-button. The unit should shut off with no time
delay. You are now ready to test the automatic start function.
To test the Automatic Transfer Switchs follow the instruction in
the operators manual you received with your transfer switch. If
you get a fault light during the initial start up or prior to start up it
is most likely a false warning light. Simply reset the A.T.S. and
start over.
Once you have completed testing of the ATS, be sure you
ALWAYS leave the system in standby mode unless servicing the
unit. For standby operation, press the "AUTO" button on the front
of the engine control. The green light should light up under the
"AUTO" button.
SETTING THE EXERCISER CIRCUIT
