** Notice **
If for any reason during the check out procedure the volt-
age and frequency are not correct, turn the selector switch
to the “STOP” position and correct the trouble before pro-
ceeding.
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 ap-
plied 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 au-
tomatic 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 ap-
plied 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 con-
trolled by the electrical and mechanical interlocks in be-
tween the two contactors in the A.T.S. panel. These inter-
locks ensure that you get a clean 'break before make' ac-
tion 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. AL-
WAYS 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 indi
cates the correct time in hours. Note: In the afternoon
you should push the button until a "P" is displayed be
side the correct hour.
4. Push the "Minute Select Button" until the display indi
cates 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 program 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 dis
played 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 dis
play 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
displayed 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.
8. With the "Hour" and "Minute" buttons, select the time
you want the engine to stop. It is recommended you
let the engine run at least 15 minutes during any exer
cise period.
9. Position the top right hand (RUN) slide switch to the
center (RUN) position.
CLOCK NOTES:
This seven day exerciser clock has seven additional pro-
gram cycles available. Always keep in mind the odd num-
ber turns the unit on and the even number shuts the unit
off. (i.e. (3 on, 4 off) (5 on, 6 off) etc.
The relay in the clock will not work unless the transfer
switch is installed and powered up. The clock relay needs
120 volts AC to operate.
