00015 BATTERY VOLTAGE TOO HIGH
• ACTIVATION: 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 ener-
gized.
• 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.
NOTE: 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, above unit off reading (bat-
tery charger charging).
2. Check Battery Charger Voltage
a. Test voltage at PCM-T3 with unit off. Must be between 11-16 VDC.
b. Test voltage at PCM-T3 with unit running. Must be between 12-16 VDC.
3. Check Voltage At Main Microprocessor
a. Check voltage reading at 3MM-23 & 3MM-34. Must be between 11-16 VDC.
b. Check Unit Data voltage reading. Must be within 0.5 VDC of reading obtained at 3MM-23 & 3MM-
34. If voltages are out with unit running, check Battery Charger. Refer to Section 8.9.12.
