Carrier TRANSICOLD Vector 8500 User Manual

62-11640 7–108
22102 SENSOR INPUT VOLTAGE HIGH INP1
NOTE
This alarm is an indication that there is a short in the DC current transformer wiring from another
(nominal 12 VDC) circuit into the transducer or CT sensor circuit.
• ACTIVATION: Voltage from main microprocessor to the sensors is greater than 5.5 VDC
• UNIT CONTROL: Engine and Electric Operation: Alarm only.
• RESET CONDITION: Auto reset when sensor voltage is correct, alarm reset or alarm may be manually
reset 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, clear the
alarm(s). (Refer to Note 1 in Notes Section, page 7-2.) 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 Wiring
If a transducer reading is not within a reasonable range of gauge reading, check wires to sensors for
short.
For CSP, check wiring from 2MM−20, 2MM−30 and 2MM−9.
For EVOP, check wiring from 2MM−25, SP−20 and 2MM−17.
For CDP, check wiring from 2MM−21, SP−20 and 2MM−10.
For ECOP, check wiring from 2MM−28, SP−20 and 2MM−14.
2. Check CT Wiring
Check wires to sensor for short from another circuit. Check wiring from 2MM−29, 2MM−12 and
2MM−23 to PCM.
3. Replace Main Microprocessor
Download data and replace main microprocessor. For complete Main Microprocessor Module replace-
ment instructions refer to Section 5.5.2.
22103 INPUT LOST CONFIGURATION
• ACTIVATION: Input Board reports an invalid configuration
• UNIT CONTROL: Engine and Electric Operation: Required Shutdown.
• RESET CONDITION: Auto reset when communication is restored, or alarm may be manually reset by
turning the unit off, then back on again.
CORRECTIVE ACTIONS:
1. Check Wiring
Check logic power connections. Check wiring at 1MM6 & 1MM1.
2. Replace Main Microprocessor
Download data and replace main microprocessor. For complete Main Microprocessor Module
replacement instructions refer to Section 5.5.2.
