PROCEDURE
Move the selector switch on the engine generator to the “RUN”
position. The engine-generator will crank and start automati-
cally. If the engine fails to start, return selector switch to the
“stop” position and correct the trouble before proceeding.
With the engine running smoothly check the no load voltage and
frequency at meters on the front panel. The voltage should be
240 A.C. and a frequency of 61.5 To 62 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 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
one half of the line to line (G1 to G3) voltage or approximately
120 volts AC. 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, turn the selector switch to the “STOP”
position and correct the trouble before proceeding.
After verifying the that 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
“AUTO” 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, the DC
interconnection wiring is incorrect. Now when the selector
switch on the A.T.S. is moved to the “DISABLE” position the unit
will go into a 3 minute cool down and then shut off. 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 accomplish 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. As 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 and the line side to close as soon as the
generator side is open. This sequence is controlled by the
electrical and mechanical interlocks in between the two contac-
tors in the A.T.S. panel. 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 the 3 minute
timer circuit and shutdown the unit 3 minutes later.
This completes your installation and unit testing. ALWAYS leave
the system in standby mode unless servicing the unit. For
standby operation, keep both the generator set and transfer
selector switches in the “AUTOMATIC” position.
SETTING THE EXERCISER CLOCK
Setting the current time and date.
1. Position the top right hand (RUN) slide switch to the left
position.
2. Push the clock's "Day Select Button" until the clock displays
a triangle under the number corresponding to the current day of
the week. (Monday is day 1, Sunday is day 7)
3. Push the "Hour Select Button" until the display indicates the
correct time in hours. Note: In the afternoon you should push the
button until a "P" is displayed beside the correct hour.
4. Push the "Minute Select Button" until the display indicates
the correct time in minutes.
5. Position the top right hand (RUN) slide switch to the center
position. The correct time and date should now be displayed.
Setting the Exerciser Program:
NOTE: The programs on this clock are grouped. i.e. 1 and 2, 3
and 4, etc. The start time is programed on the odd number and
the stop time is programed on the even number in each pro-
gram set.
1. Position the top right hand (RUN) slide switch to the right
hand position.
2. Position the top left hand (AUTO) slide switch to the center
postion.
3. Press the "Program Select Button" until No 1 is displayed on
the clock to the right of the time.
4. Push the "Day Select Button" to select the day you want the
engine generator set to start up and run. Note: You can get
more than one triangle displayed on the clock. If this happens
just keep pressing the button and it will work back through the
cycle and display only one traingle under whichever day you
desire.
5. With the "Hour" and "Minute" buttons select the time of day
you want the engine to start up.
6. Press the "Program Select Button" until number 2 is dis-
played on the clock.
7. Push the "Day Select Button" to select the day you want the
engine to stop. This must be the same day you selected in step
4 above.
