An external DC relay coil, with a minimum 2 kΩ resistance, can be connected in series from battery positive (+) to the lockout control wire. When the lockout control signal is active, it will energize the relay. The relay contacts can be used to lockout the vehicle using the key switch circuit, etc.
Alternatively, the lockout control wire can be connected to the motor speed controller (MSC) lockout/interlock input. A 10 kΩ, 1 Watt pull-up resistor to battery positive (+) should also be connected to the MSC lockout input in order to pull this input high when the charger lockout control signal is not active.
8 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.
9. PROPER CARE OF DEEP-CYCLE LEAD-ACID MOTIVE POWER BATTERIES
Motive power battery packs are subjected to severe deep-cycle duty on a daily basis. Although these batteries are designed to withstand such duty, the following precautions must be observed to obtain good performance and maximum cycle life.
CAUTION: ALWAYS WEAR PROTECTIVE EYE SHIELDS AND CLOTHING WHEN WORKING WITH
BATTERIES. BATTERIES CONTAIN ACIDS WHICH CAN CAUSE BODILY HARM. DO NOT PUT
WRENCHES OR OTHER METAL OBJECTS ACROSS THE BATTERY TERMINAL OR BATTERY TOP.
ARCING OR EXPLOSION OF THE BATTERY CAN RESULT.
1. When installing new batteries, be sure the polarity of each battery and the overall battery pack is correct.
Otherwise, battery and/or charger damage can result.
2. New batteries should be given a full charge before their first use because it is difficult to know how long the batteries have been stored.
3. New batteries and older batteries that have been in storage are not capable of their rated output until they have been discharged and charged a number of times. Consult the manufacturer of your batteries for more information.
4. DO NOT EXCESSIVELY DISCHARGE THE BATTERIES. Excessive discharge can cause polarity reversal of individual cells resulting in complete failure shortly thereafter.
5. Maintain the proper electrolyte level of wet (flooded) batteries by adding water when necessary. Distilled or deionized water is best for battery life. Never allow the electrolyte level to fall below the top of the battery plates. Electrolyte levels lower during discharge and rise during charge. Therefore, to prevent the overflow of electrolyte when charging, it is mandatory that water be added to cells AFTER they have been fully charged
– do not overfill. Old batteries require more frequent additions of water than new batteries.
6. Hard crystalline sulfates form when batteries in storage are not maintained in a charged active state.
Internal self discharge can bring about the start of this condition in as little as three days in warm temperatures. Batteries not maintained and allowed to sit in storage will self discharge, sulfate and lose capacity. Repeated charging without using the batteries between charges can recover some of the lost power, range, and life, but some permanent loss should be expected.
7. Cold batteries require more time to fully charge. When the temperature falls below 65°F, the batteries should be placed on charge as soon after use as possible.
