2. HIGH SETPOINT CALIBRATION:

The HIGH set point range spans from 10 – 15VDC. This set point is adjustable via an on board

Pot. There is a red LED adjacent to the Pot (HIGH), which illuminates when the sense input

voltage has gone above the HIGH set point. There is also a jumper adjacent to the HIGH pot,

which allows for pot calibration.

The simplest and most precise method for calibration is as follows.

1. Connect battery positive (10 - 15 VDC) to BCM terminal #1 or #2, and connect battery

negative to BCM terminal #3 or #4.

2. Measure the voltage on the jumper adjacent to the HIGH Potentiometer. The HIGH set point

will be the voltage measured at the jumper pin +10.

[HIGH SETPOINT= V measured +10 VDC]

i.e. If a HIGH set point of 14.2VDC is required, you must adjust the HIGH potentiometer

until the voltage at the HIGH POT reads 4.2VDC.

MAXIMUM RUN TIME CALABRATION:

The Maximum Run time setting is adjustable from 0 – 512 minutes (0 – 8.5 hrs). This setting

adjusts the maximum ON time for the Run output. i.e. if the HIGH set point has not been

reached prior to the maximum run time, the Run output turns OFF, and the BCM waits for yet

another LOW voltage condition.

Calibration of maximum run time is as follows:

1. Connect battery positive (10 - 15 VDC) to BCM terminal #1 or #2, and connect battery

negative to BCM terminal #3 or #4.

2. Measure the voltage on the jumper adjacent to the MAX. RUN TIME Potentiometer. The

MAX RUN TIME set point will be as follows:

[MAX RUN TIME = (V measured * 512)/5)]

i.e. If a MAX RUN TIME of 5 minutes is required then you must adjust the MAX RUN

TIME potentiometer until the voltage at the MAX RUN TIME POT reads 0.0488 VDC.

V meas. = (MAX RUN TIME * 5)/512 = (5*5)/512
