Troubleshooting
24 Volt Open Chargers Can Overheat
Open chargers that are contained within a small, enclosed control panel may overheat. This is especially true for 24 volt chargers. Overheating can cause the potentiometer within the charger to fail. Open chargers that have improved components with fitted assemblies are stamped with a date from 13September 2007. These chargers are not approved by the Underwriters Laboratories Inc.. Also, open chargers that have a serial number break from 0709-1531 are fitted assemblies with the printed circuit board that have a version of 6.3. These chargers are not approved by UL. The new circuit boards allow the temperature compensation to be disabled by moving the jumper that is on the printed circuit board from "INT" to "NON". The new circuit boards can be placed in either vertical orientation regardless of the direction that is shown on the label.Digital Warnings on the Control Panel
Battery chargers are equipped with circuitry for temperature compensation. Occasionally, the battery chargers will intermittently initiate an erroneous alarm for either a Low Battery Voltage or a High Battery Voltage. The erroneous alarms are attributed to the thresholds that are set for the alarms in the digital controller. The thresholds that have been set may be improper for battery chargers that have compensation for temperature.Incorrect Supply Voltage
Battery chargers can fail to operate correctly if a charger is used with the incorrect rating for the supply voltage. Cross-reference the supply voltage that is listed on the label for the ratings of the charger against the auxiliary supply voltage which is connected to the charger.Loose Connections at the Terminals
Wires that are connected to the charger or wires that are connected within the charger may become loose. Check the wires. Reconnect the wires to the terminals. Use the correct size of tool to clamp the wires. A flat screwdriver that has a maximum width of 3.5 mm (0.1378 inch) that does not have a flared tip should be used. Use a tool to push down on the terminal in order to open the jaws. Use special care in order to ensure that the wires are correctly inserted into the terminals. Also, check the crimped terminals to the internal ammeter on chargers that are the type of box. The crimped terminals may be faulty.Incorrect Battery Type
The chargers are designed to be used with only batteries that are vented and lead acid. The chargers may not operate correctly if the chargers are used with a NiCd battery.Output Voltages may be Incorrect
The output voltage of the charger may be different from the voltage that is specified in Table 1 due to the following reasons:
The charger will not operate normally if a battery that is not in good condition is connected or if no battery is connected. The output will only be up to half of the rated output voltage.
If the batteries are not charged, the output voltage will be lower than the voltage that is specified in Table 1. Charge the battery. Retest the battery. The
