00014 HIGH A/C AMPS
• ACTIVATION: AC Current Sensor 1, 2, or 3 is greater than 28.5A for 3 seconds.
• UNIT CONTROL: Refrigeration system shutdown and alarm with PSCON still energized.
• RESET CONDITION: Auto reset after 14 minutes if AC Current Sensor 1, 2, and 3 reading is less than 27
amps or alarm may be manually reset via keypad or by turning unit off then back on.
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. Perform Pretrip Check - Clear Active Alarm list, then run Pretrip & check for any new alarms. Any active
alarms must be corrected and cleared before proceeding.
2. Check Current Draw
a. Use a clamp around A/C ammeter to check amps at power wires. Must be 1.0 Amp of reading in Unit
Data.
b. Check A/C amps with compressor running. Must be greater than 5 Amps.
c. Compare A/C Amp readings between L1-L2-L3. Maximum allowable difference is 10 Amps.
3. Check Wiring
a. Inspect wiring from CT to 1CCB. Check related Splice Points. (See wiring schematic
Section 10.3
)
b. Verify there is no physical damage to harness, no damage, moisture, or corrosion in connectors.
00015 BATTERY VOLTAGE TOO HIGH
• ACTIVATION: Battery voltage at the main microprocessor is greater than 17 VDC.
• UNIT CONTROL: Refrigeration system shutdown and alarm with PSCON still energized.
• 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.
Voltage with unit running should always be higher than voltage with unit off due to battery 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 8.8.12.
