BAD F2 OR F3 FUSE
TRIGGER-ON: F2 &/or F3 has been open for more than 2 seconds: F2, F3
UNIT CONTROL:
RESET CONDITION: Alarm may be manually reset via keypad or by turning the unit off,
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 Page 7-1) Operate the unit through the appropriate modes to see if any active alarm
occurs. Continue with the steps below as necessary.
1
Check Unit Operation
a. Did engine shut down?
2
Check Fuses
a. Locate blown fuse(s).
b. Verify fuse size.
c. Inspect fuse & fuse holder.
3
Check Run Relay Circuit
a. Use Component Test Mode to test
actual current draw of the circuit.
(Refer to Section 5.1.2.)
Check for voltage between
MPQC-8 and ground.
b. Check for voltage between
MPQC-4 and ground.
4
Check Speed Relay Circuit
a. Use Component Test Mode to test
actual current draw of the circuit.
(Refer to Section 5.1.2.)
Check for voltage between
MPQC-8 and ground.
b. Check for voltage between
MPQC-3 and ground.

ALARM / CAUSE
Engine operation: Alarm Only. If the engine shut off, refer to troubleshooting
steps below to correct.
Standby operation: Additional verification required if the "No Power"
configuration is set for "Installed and Shut Down" the refrigeration system will
shut down with the alarm on and PSCON still energized.
then back on again.
CORRECTIVE ACTION
Yes, Check F3.
No, Check F2.
Will have open circuit.
Refer to Section 2.13.
Must be correct rating for circuit. (See wiring schemat-
ic. Section 10.)
Terminals tight; No signs of overheating, melting or
discoloration.
Component FET or board LED (refer to Table 5-1)
must be illuminated.
View current draw in Data List.
Refer to Section 2.12 for normal current values.
Voltage should be approximately 12 VDC.

Questions and answers
Как это работает
The Carrier VECTOR 1550 Series is a hybrid diesel/electric refrigeration system designed for insulated trailers. It maintains cargo temperatures within precise limits. The unit operates using electrical power and has a generator directly bolted to the engine.
Key components and functions include:
- Generator (GEN): Supplies electrical power for operation.
- Engine Coolant Temperature Sensor (ENCT): Monitors engine coolant temperature and provides data for system control.
- Unloader Solenoid Valve (USV): Opens during low load periods to bypass compressed gas, balancing compressor capacity and reducing power consumption.
- Liquid Injection Solenoid Valve (LIV): Opens during high compressor discharge temperatures to inject refrigerant and cool the compressor.
- Condenser Coil: Helps dissipate heat from the refrigeration cycle.
The unit’s microprocessor controls the refrigeration operation, including temperature settings and supply air limits.

Куда подключать интерфейс технического специалиста
The technician interface on the Carrier VECTOR 1550 Series is connected using the Technician Interface Connector Assembly (P/N 22-60661-00). This allows the technician to access the Technicians Configuration/Test Mode for changing configurations, testing unit components, and servicing the refrigeration system.
