** 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 3 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 3
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 shut down 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 hour. Note: For PM be sure there is a "P" 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 programmed on the odd number and
the stop time is programmed 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
position.
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 triangle 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.
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 exercise 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 program
cycles available. Always keep in mind the odd number 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.
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 the 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.
