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 5 minute
timer circuit and shut down the unit 5 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.
