BOX TEMP OUT-OF-RANGE (Continued)

Check Refrigerated Compartment Doors
1
a. Inspect all box doors.
2
Defrost Evaporator
a. Initiate Manual Defrost Cycle.
3
Check For Any Shutdown Alarm(s)
a. Check the Alarm List for any Shut-
down Alarms.
4
Check For Low Refrigerant Pressure Alarm
a. Check for alarm 18.
5
Check Refrigerant Charge
a. Check refrigerant level in the re-
ceiver.
6
Check System Pressures
a. Install Manifold Test Set and check
and compare compressor dis-
charge & suction pressures with
those shown on the microproces-
sor.
7
Check Evaporator Section
a. Check evaporator section, return
air bulkhead, air chute, cleanliness
of evap. coil and airflow.
8
Perform Pretrip Check
a. Clear Active Alarm list, then run
Pretrip & check for any new
alarms.
9
Check For Low Delta-T
a. Read Delta-T from Unit Data List.
ALARM / CAUSE
CORRECTIVE ACTION
Must be closed, no air leakage.
Must terminate automatically.
All ice cleared from all evaporator coils.
Alarm conditions must be corrected and the alarm
cleared to continue.
Alarm conditions must be corrected and the alarm
cleared to continue.
Generally, level should be between upper & lower sight
glasses with a refrigerated compartment temperature
of 1.0°C (35°F) or lower. refer to Section 8.5.4
Suction & Discharge Pressures must have the same
reading on gauges & on microprocessor display.
Pressures must be in the normal range for ambient &
refrigerated compartment temperature conditions.
NOTE: Microprocessor suction (CSP) and evapora-
tor (EVOP) pressure readings have a maximum
value of 7.5 bar (100 psig). The actual suction pres-
sure must be lower in order to perform this test.
Refer to Section 9.4.10
Any active alarms must be corrected and cleared be-
fore proceeding.
In Cool, the Delta-T reading must be greater than -
0.56°C (-1°F).
Note for Delta-T readings a higher number after the "-"
sign is "greater than". For example, -3°C is greater
than -2°C.
In Heat the Delta-T must be greater than 0 (SAT must
be higher than RAT).

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.

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.
