Press the PROGRAM button
once more
to set the day and time for ending the
exercise. A default time AM 12:00 appears in the display. A small 2 appears to

Move the slider on the SET switch to the "run" position. The exerciser time clock
is now programmed to start the emergency generator at the desired day, time and
for the desired duration.
NOTE:
It is possible to program one to eight "on - off" cycles or transitions for the
following day combinations: One to eight "on-off" cycles any day of the week; One to
eight "on-off" cycles Monday to Friday inclusive; One to eight "on-off" cycles both
Friday and Saturday only; One to eight "on-off" cycles Monday to Saturday inclusive;
One to eight "on-off" cycles Monday to Sunday inclusive; All day combinations can have
any combination of "on -off " cycles
. Normally the exerciser time clock will only
require one "on-off" cycle once per week.
The programming steps given above describe
how to exercise the generator once a week.
EXAMPLE
:
Suppose that the desirable day
and time for exercising the generator is Saturday at 5:00 AM. Move the slider of the
SET
SWITCH
to the right (P in circle) position. Press the
DAY BUTTON

BUTTON
repeatedly until the desired time
AM
5: 30 are displayed. The generator is to be
shut down after exercising for 10 minutes. With the slider of the
SET SWITCH
still in the
right (P in circle) position press the PROGRAM BUTTON
once
. The display will show
a continuous default time of
AM
12:00. The day arrow(s) disappears. The small 1 will
change to a 2 and the lamp symbol disappears. Press the DAY BUTTON (1..7) again
repeatedly until the day arrow appears under day 6. Press the
HOUR BUTTON
(h) followed
by the

programmed to start the generator at 5:30 AM on Saturday morning and run for 10
minutes then shut down at 5:40 AM of the same day Saturday. Following this procedure,
the generator can be exercised as frequently as desired.
