The relay in the clock will not work unless the transfer
switch is installed and powered up. The relay needs 120
volts AC to operate.
If, when you finish programming the clock, you get an
“EEEE” on the display, it stands for error. The most
common error is that the day of operation has not been
properly set at each step or a program has been turned
on and not turned off. (i.e. programs not properly grouped
1& 2, 3 & 4, 5 & 6, etc.)
On the face of clock is a small button marked “R”, this
is a reset switch. Depressing this switch will remove all
programming in the clock including the time, Use a
small screwdriver or the tip of a pencil to depress this
button. This should be used only as a last resort.
INITIAL START UP
*************
***** WARNING *****
*************
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 installa-
tion before starting the engine:
F
Engine oil.* Check level & fill as required with
proper grade/qty.
F Engine coolant.* Check level & fill as required
with proper mixture.
F
Unit mounting base properly bolted down.
F Clearance for service and maintenance on all
sides.
F Proper fuel line material, and size.
F
All fuel line connections tight.
F Fuel line protected and a moisture trap installed
(may be required for N.G.).
F LP/NG pressure O.K. 4-6 Oz. (7-11" WC).
F
Battery connections clean and tight.
F
Battery fully charged.
F All A.C. and D.C. wiring installed and properly
protected.
* Refer to engine owners manual for proper
levels and type.
After completing the above checklist, the engine-
generator set is ready for the initial start-up test.
PROCEDURE
Move the selector switch on the engine generator to the
“RUN” position. The engine-generator will crank and
start automatically. If the engine fails to start, return
selector switch to the “stop” position and correct the
trouble before proceeding.
With the engine running smooth, check the no load
voltage and frequency at terminals G1 and G3 on the
generator terminal block in the A.T.S. The voltage
between G1 and G3 should be between 255-260 volts.
The frequency should be between 60.0 to 60.5 hertz. The
voltage should also be checked between the hot termi-
nals (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 one half of
the line to line (G1 to G3) voltage.
** Notice **
If for any reason during the check out procedure the
voltage and frequency are not correct, turn the selector
switch to the “STOP” position and correct the trouble
before proceeding.
After verifying the voltage and frequency are correct, turn
the selector switch to the “STOP” position. The unit
should shut off with no time delay. You are now ready to
test the automatic start function.
Move the selector switch on the engine generator set to
the “AUTOMATIC” position. Next move the selector switch
on the A.T.S. panel to the “START” position. The unit will
go into a 10 second start delay and then start up. If it fails
to start at this time, check your DC inter connection
wiring. When the selector switch on the A.T.S. is moved to
the “DISABLE” position the unit will go into a cool down
period and then shut off. The cool down period is 3
minutes. As long as line power is still applied to the
transfer switch during this test period the A.T.S. will not
transfer the load to the generator.
Next you need to test the complete system. To accom-
plish this you will have to fail the incoming line power to
the A.T.S. panel. First move both selector switches to the
automatic position. Then fail the incoming power. All the
loads connected to the A.T.S. should now be dead. The
engine generator set will go into a 10 second start delay.
At the end of the start delay the unit will start up. A soon
as the engine generator set reaches operating speed the
generator side contactor will close and the load will be
applied to the engine generator.
Restoring the line power will cause the generator side
contactor in the A.T.S. to open. The line side contactor will
close as soon as the generator side contactor clears the
mechanical interlock and closes the electrical interlock.
These interlocks ensure that you get a clean ‘break
before make’ action in the transfer switch.
The restoration of line power also sends a stop signal
to the engine generator set. This stop signal will activate
a cool down timer circuit. The engine generator will shut
down 3 minutes later.
This completes your installation and unit testing.
ALWAYS leave the system in automatic mode unless
servicing the unit. For automatic operation, keep both the
generator set and transfer selector switches in the
“AUTOMATIC” position.
