(1)-Code 1442 - Weak Battery Logic: This fault occurs when the engine is starting (cranking) and the voltage of the battery drops below the “Weak Battery Voltage threshold" for the time set in the “Weak Battery Voltage Set Time". Possible Causes: 1. Weak or discharged battery. 2. Battery connections are loose or dirty. 3. “Weak battery" voltage threshold parameter is set too high. (2)-Insufficient battery charging voltage. 5. Faulty engine DC alternator. 6. The base board or harness is faulty. Diagnosis and Repair: 1. Weak or discharged battery. a. Measure the voltage of the battery with a voltmeter. Battery voltage should be 12 VDC or greater in a 12 V system or 24 VDC or greater in a 24 VDC system. If the battery voltage is low, check the electrolyte level in the battery. Replenish the electrolyte level if low and recharge the battery; the specific gravity for a fully charged lead acid battery is approximately 1.260 at 80 F (27 C). b. If the battery cannot hold adequate voltage, then replace the battery. 2. Battery connections are loose or dirty. a. Clean and tighten battery terminals and battery cable connectors. If the battery cable connectors are cracked or worn out, then replace. 3. "Weak battery" voltage threshold parameter is set too high. a. Ensure that the Weak Battery Voltage parameter is set to an appropriate voltage value that takes into account voltage drop during cranking (refer to the parameter list to see the default value). To access the battery voltage setup menu from the operator panel, go to Setup > OEM Setup > OEM Engine Setup > Weak Battery and change the weak battery voltage parameter of the control accordingly. 4. Insufficient battery charging voltage. a. Ensure that the battery charger is charging the battery at an acceptable rate. Adjust the charge rate if the rate is below the recommendation of the manufacturer. b. If the battery located far from the battery charger, ensure that a proper wire size is used to compensate for voltage drop. 5. Faulty engine DC alternator. a. Check the engine DC alternator. If normal charging voltage is not 12 to 14 VDC in a 12 V system or 24 to 26 VDC in a 24 V system then replace the DC alternator. 6. Check to see if the base board or harness is faulty. a. Measure the battery voltage at the battery terminals and then measure the battery voltage at the base board input. Measure the voltage at B+ (J20-9, J20-10, J20- 20, J20-21) and B- (negative) input (J20-2, J20-4, J20-7, J20-12). • If the voltage at the battery terminals and the control is the same, replace the base board. • If the voltage at the battery terminals and the control is not the same, check the harness and replace if necessary. 13.61 Code 1443 - Dead Battery
Code 1312 - Config Input #2 Fault Logic: Configurable input #2 fault is active. Possible Causes: 1. Condition for which "Configurable Input #2" is configured for is active. 2. “Configurable Input #2 Active State Selection" parameter is configured incorrectly. 3. Incorrectly wired; or open circuit or short circuit in the wiring. 4. The base board is faulty. Diagnosis and Repair: 1. Condition for which "Configurable Input #2" is configured for is active. a. Check the condition for which "Configurable Input #2" has been configured for; ex. if "Configurable Input #2" was configured to become active when the fuel level is low, check the fuel level and add fuel if needed. After the issue is resolved, press the Reset button on the Operator Panel in order to clear the fault, if the fault does not clear go to step 2. 2. “Configurable Input #2 Active State Selection" parameter is configured incorrectly. a. With InPower or through the Operator Panel check the switch input setting (active closed or active open) for Configurable Input #2. Ensure that the switch input setting is correctly set. If “Configurable Input #2 Input Function Pointer" parameter is set to default and if “Configurable Input #2 Active State Selection" parameter is set to “active closed", input 2 (event/fault code 1312) will become active when TB1-14 (input 2) and TB1-15 (ground) are connected (shorted) together. If “Configurable Input #2 Input Function Pointer" parameter is set to default and if “Configurable Input #2 Active State Selection" parameter is set to “active open", input 2 (event/fault code 1312) will become active when there is an open circuit between TB1-14 (input 2) and TB1-15 (ground). To access the input configuration on the operator panel go to Setup > Configurable I/O > Config Input #2 Menu > Active and set this parameter appropriately for the application. 3. Incorrectly wired; or open circuit or short circuit in the wiring. a. Check the wiring at TB1-14 (input 2) and TB1-15 (ground) for an open circuit, short circuit, or a miswired condition. 4. The base board is faulty. a. If the previous steps do not reveal any problems but event/fault code 1312 is still active, replace the base board.
