Alarm
NO.
Steps
ALARM / CAUSE
CORRECTIVE ACTION
15
BATTERY VOLTAGE TOO HIGH
•
TRIGGER–ON: Voltage at the microprocessor is greater than 17 VDC.
•
UNIT CONTROL: Engine operation: engine and unit shutdown and alarm. Standby operation:
refrigeration system shutdown and alarm PSCON de energized
refrigeration system shutdown and alarm. PSCON de--energized.
•
RESET CONDITION: Auto Reset after 15 minutes when the voltage at the microprocessor is between
11 and 14 VDC, or alarm may be manually reset via keypad 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 (see reset condition above). Operate the unit through the appropriate modes to see if any active
alarm occurs. Continue with the steps below as necessary.
1.
Check Battery Voltage
a. Test voltage at battery with unit off.
Must be between 12--16 VDC
b. Test voltage at battery with unit
running.
Must be between 12--16 VDC
2.
Check Battery Charger Voltage
a. Test voltage at battery charger output
terminal with unit off
Must be between 12--16 VDC
b. Test voltage at battery charger output
terminal with unit running.
Must be between 12--16 VDC
3.
Check Voltage At Microprocessor
a. Check voltage reading at
microprocessor input (QC1+ to
QC2--)
Energize circuit. (See Note 2)
Must be between 12--16 VDC
b. Check voltage reading on
microprocessor display
Must be within 0.5 VDC of reading obtained in 3a (above)
16
BATTERY VOLTAGE TOO LOW
•
TRIGGER–ON: Voltage at the microprocessor is less than 10 VDC (except when the engine starter is
engaged)
g g )
•
UNIT CONTROL: Unit Shutdown & Alarm. Alarm condition only if activated while starting unit.
•
RESET CONDITION: Auto Reset after 15 minutes when the voltage at the microprocessor is between
11 -- 14 VDC, or alarm may be manually reset via keypad 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 (see reset condition above). Operate the unit through the appropriate modes to see if any active
alarm occurs. Continue with the steps below as necessary.
1.
Check For Alarm 51
a. Check for Alternator Not Charging
Alarm
Alarm conditions must be corrected and the alarm cleared
to continue
2.
Check Battery Voltage
a. Inspect battery cable ends and posts
Must be clean and tight
b. Test voltage at battery with unit off.
Must be above 11 VDC
c. Test voltage at battery with unit
running.
Must be above 11 VDC
d. Test specific gravity of battery
(Check for battery specifications)
e. Perform load test on battery (Follow
battery manufacturer’s procedure)
(Check for battery specifications)
3.
Check Voltage At Microprocessor
a. Check voltage reading at
microprocessor input (MPQC1+ to
MPQC2--).
Energize circuit. (See Note 2)
Must be above 11 VDC
b. Check voltage reading on
microprocessor display
Must be within 0.5 VDC of reading obtained in 3a (above)
