SELECTOR SWITCH:

If delayed response of 30 seconds is required (activa-
tion of photocell operation), move selector switch
labeled (DELAY, QUICK, SW) to the Left position
marked (DELAY).

If instance response is required move selector switch
to the center position marked (QUICK).

POTENTIOMETER:

Adjust potentiometer labeled (MIN MAX) for desired
light level actuation. If adjusted to the extreme left
(MIN position), turn ON will be 1 to 2 footcandles. If
adjusted to the extreme right (MAX position), turn ON
will be approximately 100 footcandles.

IMPORTANT: The potentiometer allows you to adjust
a turn ON ranging from 1 to 100 footcandles. OFF will
be 3 times the ratio of the ON foot candle level (see
example “B” below).

When using photocell input, the following can be
accomplished:

A. Photocell ON/Time OFF

B. Photocell ON/ Time OFF/ Time ON/ Photocell OFF.

DRY CONTACT INPUT

When connecting dry contact closure (i.e. remote
maintained SPST switch) to universal input termi-
nal labeled (1 2 3), connect wires to terminals 2
and 3. DO NOT USE TERMINAL 1. See illustration

REVIEW/MODIFY/ADD/DELETE

REVIEW: Reviewing is done in the set mode. Press
mode key until first setting appears. Pressing the
ENTER button will advance the counter (which
appears in the two digits on the right) and shows you
the next schedule event entered. Events are num-
bered based on the order with which they were
entered, and not on when they will be executed, so the
first event you set will be #01, the second #02, etc...

MODIFY: During the review process, the DAY, HOUR,
MIN, and ON/OFF keys can all be used to modify the
settings. You can use the first three keys to modify
when the event will take place, and the ON/OFF key to
change an ON event to an OFF event, or visa-versa.
ONCE YOU HAVE MADE THE NECESSARY
CHANGE, YOU MUST PRESS THE ENTER KEY (for
each change) TO STORE THEM.

ADD: You may add events at any time by pressing the
mode key until the unit is in the set mode. Then press
ENTER key to advance to the next open set point.
Enter new schedule as indicated in section “To Set
Schedule”.

DELETE: If you choose to delete a schedule, simply
modify the HOURS and MINUTES, until the time
display reads --:--. This will occur after scrolling past
11 P.M. with the HOUR key and “59” with the MIN
key. Then press ENTER to delete the event.

OVERRIDE

In order to temporarily change the current ON or OFF
status of a load, simply press the override key. This
can only be done when the unit is in the RUN mode.
The load status will flash indicating that this is a
change from a scheduled event.

In order to cancel the override, press override
key again.
