INTRODUCTION
The UV-OV Relay is a device which continuously monitors the voltage of a battery system and
detects overvoltage and undervoltage conditions. A set of contacts are provided for each of
these conditions. The values of the overvoltage and undervoltage detection points are easily
and independently programmable by accessible “DIP” switches behind the removable cover.
An adjustable time delay of 8 to 150 seconds is provided.
INSTALLATION
Figure 1 is a view of the programming switches with the snap-on top cover removed. Refer to
this figure when programming the unit.

RUN
(a) Select the desired undervoltage trip point from the column to the far right in table 1 below.
(b) Set switches #1, #2 and #3 to the settings shown in table 1 corresponding to the
selected trip point in step (a).

(c) Select the desired overvoltage trip point from the column to the far right in table 2 below
(d) Set switches #4, #5, and #6 to the settings below in table 2 corresponding to the
selected trip point in step (c).
(e) Set switch #7 to “RUN” operation if it is not already in that position. This allows
approximately 1 second of time delay for the trip points to act, and filters alternator ripple.
(f) For mechanical installation, refer to figure 3 for the hole pattern and sizes.
(g) For electrical installation, refer to figure 2 which shows the connections to various
parts of the vehicle. The alarm contacts can be connected to alarm lamps via ground
or +12 volts. Figure 4 shows a scheme for a ground hookup while Figure 5 shows
a hookup for +12 volts.
