Given the time and cost
associated with a failed product, Quality is our Number
1 Goal. Over 30% of manufacturing time is spent on Quality
Controls steps to assure that you have the most reliable
photocontrol available. For over 50 years, Quality and
Performance has been our central mission.

Good Information Saves Time and Money
Fact — Almost 100%
of all field issues can be resolved simply by following
our Trouble Shooting/Testing Guide. Over half (1/2) of
our returns are classified as “Fully Operational”.
This is a strong indicator that the user incorrectly installed
the photocontrol. The testing procedures found in this
guide are the same as those we perform at the factory
for returns.
Properly installed and tested, your Precision photocontrol
should perform flawlessly for years. As you read the installation
instructions, here are five (5) basic areas to consider
when ordering our photocontrols.
During
Installation:
• Proper Voltage • Correct Wiring • Know
the total lighting load (wattage and how many lighting
fixtures) are to be switched • Directional
Orientation • Understanding the Time Delay
feature
Installation
Procedure:
A.
Always turn off the power at the fuse or breaker box before
installing a photocontrol.
B. Proper Voltage — Make sure that your
line voltage matches with the model you purchased. With
the exception of our dual rated (105-285V) models, a 120-volt
model will not work on 240 volts and will, in fact, be
destroyed. Using a 240V control on 120 volts, the unit
will not work but will not be destroyed.
C. Lighting Load — Most of our best selling
models are rated at 1000VA or 1800VA. The VA rating is
equivalent to the same number of incandescent watts or
a “tungsten load”. For an inductive or ballast
load (HID or High Pressure Sodium), the power factor (ballast
load) must be taken into account to determine if the right
photocontrol is being used. Generally speaking, we recommend
not exceeding 1000 watts HID when using an 1800VA model
or a 400-watt ceiling for 1000VA models.
D. Directional Orientation — For best results
be sure to position the photocontrol “window”
away from obstructions and in the direction of the most
natural light. Mounting under eaves or in front of trees
will cause the photocontrol to turn on earlier in the
day. Make sure that your mounting is also directed away
from any artificial light sources that can interfere with
normal operation at night (cycling on and off).
E. Understanding Time Delay Feature — With
the exception of our electronic, locking type series (5
second response time), most of our models operate with
an inherent time delay. When the photocontrol is powered
up, the light or lights will stay on initially for approximately
60 seconds. Once the light turns off, cover the entire
photocontrol housing with a glove or some other dark covering.
After 60 to 90 seconds, the light should turn back on.

Troubleshooting Guide
Before
referring to this guide, please be sure you have read
all operational material literature and have installed
the unit according to directions. Also, make sure you
are using the correct model for the correct application.
Very important.Make sure you
have followed the installation procedures.
If you need to call for additional technical help, we
will inquire if this testing was done. If you would
still like to return the unit, even after consulting
our guide, please refer to our Return Procedure as outlined
in the Warranty.
Of the six possible wiring combinations for
the direct wire-in control, only one is correct. Listed
(to the right) are those combinations and the results.
