User’s Manual
8. VEHICLE LOCKOUT CONTROL (OPTIONAL)
The charger is equipped with a lockout/interlock relay to prevent vehicle/equipment operation while the charger
is in use. If the charger is configured for on-board use, the lockout relay will be active while AC power is
applied to the charger. If the charger is configured for off-board use, the lockout relay will be active while a
valid battery is connected to the charger.
The charger lockout relay has normally closed (NC), common (COM) and normally open (NO) dry contacts.
Connection to the relay is available through the green connector located on the charger. Please refer to Figure
8-1 to identify the lockout relays terminals.

9. REMOTE LED (OPTIONAL)
An optional remote LED can be connected to the 15 pin communications port. The single LED can display
three (3) colors to indicate charger status and fault information. It will indicate the same conditions as in
sections 13 and 14 of this manual.
10. BATTERY TEMPERATURE SENSOR (OPTIONAL)
WARNING: IT IS IMPORTANT TO MOUNT THE TEMPERATURE SENSOR ON THE BATTERIES FOR
PROPER TEMPERATURE COMPENSATION.
The temperature sensor (if present) should be attached to a battery post near the center of the battery pack. If
the threaded stud is long enough above the battery jumper nut, attach the probe with another nut. Torque this
nut to proper specifications. If the stud is too short, the nut holding the jumper wire will need to be removed.
Open or remove the load and charging circuits to the batteries. Remove the nut and add the sensor, then
torque the nut to the proper specifications. Then close or connect the load and charging circuits back to the
batteries.
Securely fasten the temperature sensor cable to protect the sensor from being torn from the battery.
Secure the sensor cable to a fixed object to ensure the probe will not be pulled loose. Use a cable tie mount
on the battery or on the adjacent battery, if necessary.
