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
on inside label.

INSTALLA
TION
UNIT IS TO BE INSTALLED BY A LICENSED ELECTRICIAN
1. To remove unit from enclosure: Push tab on right to
swing unit to the left and remove.
2. Mount the enclosure at eye level using screws or
other suitable fastening device. Bring supply and
load wires in through the bottom or side knockouts.
DO NOT USE TOP.
Clock input wires to controller must be from a dedicated source i.e. no other loads connected to the
same circuit.
3. Install standard 9 volt lithium or alkaline battery
(not supplied) by gently squeezing the right side of
the battery cover on the front of unit and pull to
open. Pull out the battery connector and connect
the battery. Reinstall battery cover. Lithium should
be replaced every 3-5 years; alkaline every year.
NOTE: Unit can be fully programmed using battery
power only
4. Reinstall unit by reversing step #1 above and connect wires to unit as per suggested wiring diagrams. See illustration on enclosure label.
Do not wire the photocell or remote maintained
switch while AC current is applied to the unit.
Do not apply any voltage from external source
to universal input terminals.
PHOTOCELL INPUT
When connecting Photocell (EPC1 ) to Universal Input
terminal labeled (1 2 3), connect wires to terminals 1
and 2. DO NOT USE TERMINAL MARKED 3. See
illustration on enclosure label.

SELECTOR SWITCH:
If delayed response of 30 seconds is required (activation 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 terminal labeled (1 2 3), connect wires to terminals 2
and 3. DO NOT USE TERMINAL 1. See illustration
on inside label.

With dry contact closure used, the following can be
accomplished:
For Model DGU100:
When the output is OFF, closure of the remote switch
will turn it ON until the next scheduled OFF.
When the output is ON, close then open the remote
switch to turn it OFF (until the next scheduled ON).
For Model DGUM100:

IMPORTANT NOTES CONCERNING
THE UNIVERSAL INPUT:
1. If the universal input is not being used for Photocell
or Dry contact closure, move selector switch
labeled (DELAY, QUICK, SW) to the right position
marked (SW).
2. Photocell or remote switch can be wired up to 500
feet from timer using 2 wire, #18 to #22AWG,
between universal input terminal and photocell or
switch.
3. Do not put excessive pressure on potentiometer.
Use thumb and forefinger or small screwdriver to
adjust for light level. Avoid shorting screwdriver to
upper board.
4. Light level adjustment operates only with Tork
Photocell Model EPC1.
5. Remote switch input is designed for maintained
switch.
