00015 Battery Voltage Too High
• ACTIVATION: Battery voltage at the main microprocessor is greater than 17 VDC.
• UNIT CONTROL: Engine Operation: Engine and unit shutdown and alarm.
Electric Operation: Refrigeration system shutdown and alarm with PSCON still
energized.
NOTE
RESET CONDITION: Auto reset after 15 minutes when the voltage at the main microprocessor is
between 11 and 14 VDC, or alarm may be manually reset using the display mounted keys or by
turning the unit off, then back on again.
Follow the steps below until a problem is found. Once a repair or correction has been made, the active alarm
should clear itself (refer to reset condition above). Operate the unit through the appropriate modes to see if any
active alarm occurs. Continue with the steps below as necessary.
Corrective Actions:
1. Check Battery Voltage
a. Test voltage at battery with unit off. Must be between 11-16 VDC.
b. Test voltage at battery with unit running. Must be between 12-16 VDC.
NOTE
Voltage with unit running should always be higher than voltage with unit off due to battery charging.
2. Check Battery Charger Voltage at the Power Module
a.
Test voltage at ALT+ in the PM with unit off. Must be between 11-16 VDC
.
b.
Test voltage at ALT+ in the PM with unit running. Must be between 12-16 VDC.
c. Check Unit Data voltage reading. Must be within 0.5 VDC of reading obtained at ALT+. If voltages are
out with unit running, check Battery Charger. Refer to Section 8.9.11.
