NSi Industries DGUM100 - Manual

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.

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.
