Low Voltage Disconnect Operation & Installation
1. Connect terminal 88A to the vehicle load.
2. Connect terminal 88, indicated by a red battery symbol, to the positive
terminal on your battery.
3. Torque the hardware on both of the main terminals 88 and 88A to 13
ft·lbs.
4. Connect the 4-way wire harness to the low voltage disconnect twisting
the connector end until it locks.
• The device automatically detects the supply voltage.
• The command pushbutton will manually open and close the main con-
tacts.
• The device automatically disconnects the battery if the voltage drops
below the threshold voltage for at least 1 minute.
• The device automatically reconnects if the voltage rises 0.5V above the
threshold for at least 1 minute.
• The INHIBIT line will prevent automatic operation when connected to
a positive voltage (ie: the INHIBIT line receives positive input from igni-
tion power while the vehicle is operating)
• The threshold voltage can be changed using the Threshold Adjustment
Diagram and Procedure (see next page).
• The device has built-in temperature sensor that will activate the
INHIBIT line if overheating occurs. This will disconnect the device and
allow it to cool. The device will automatically reconnect once the tem-
perature lowers.
• The manual command pushbutton can be installed in any location that
is convenient for the user. We recommend installing the push button
on the dashboard.

• See diagram for required equipment.
• Threshold voltage can be set and stored in the LVD’s memory using
this procedure. This value will remain stored in the system memory
even if the LVD is disconnected from power.
• When the device is in Threshold Adjustment Mode the LVD cannot
activate the main contacts.
• By default this value is set at 12.1V.
Threshold Adjustment Instructions
1. Connect the device to the power supply as shown in the diagram.
2. Verify that the LVD command switch is connected to ground. It will be
easiest to use a rocker switch for this purpose.
3. Activate the power supply
4. After 2 seconds, the LAMP will turn ON and blink twice alerting the
user that Threshold Adjustment Mode is active.
5. Set the power supply to the desired voltage for the LVD threshold.
6. Press the rocker switch so that the button is no longer connected to
ground.
7. Verify that the LAMP displays a sequence of long, slow blinks. This will
tell the user that the new threshold value has been set and stored.
Blink Sequence Description
No Blink Main contact open, standby mode
Short Blinks Main contact closed
3 Blinks Automatic disconnection countdown
4 Blinks Automatic connection countdown
2 Blinks LVD ready to read new threshold value
Slow Blink New threshold value stored in memory
Fast Blink Error: switch operation failed
5 Blinks Failed attempt to enter Threshold Adjustment Mode
6 Blinks Thermal overheating protection active
