UNIT DESCRIPTION
2.1 INTRODUCTION
APX control system equipped units may start automatically at any time the START/RUN-OFF
switch (SROS) is in the START/RUN position. Also, the unit may be fitted with two way commu-
nication equipment that will allow starting of the unit from a remote location even though the
switch is in the OFF position.
Be aware of HIGH VOLTAGE supplied at the power plug or from the generator. When perform-
ing service or maintenance procedures: ensure any two way communication is disabled in
accordance with the manufacturer’s instruction, ensure the START/RUN-OFF switch is in OFF
position and, whenever practical, disconnect the high voltage source, lockout/tagout the
receptacle and disconnect the negative battery connection.
This manual contains operating data, electrical data and service instructions for the refrigeration unit listed in Table
2–1. Additional support manuals are listed in Table 2–2. The unit model/serial number plate is located inside the
unit on the frame as shown in Figure 2.1.
2.2 GENERAL DESCRIPTION
The Vector 8100 unit is an all electric, fully charged, pre-wired, refrigeration/heating “nose mount” unit. The unit is
used on insulated refrigerated compartments to maintain cargo temperatures within very close limits.
Electrical power is supplied to the unit from an external source, at the power supply receptacle (PSR).
The control system includes a manual switch, control modules, fuses, and associated wiring. High voltage
contactors, fuses and the contactor control boards are located in the control box. Contactors for electric power are
located in the standby box (see Figure 2.3). The unit may be equipped with an optional remote light bar which
mounts separately on the front outside corner of the refrigerated compartment.
Temperature control is provided by the Carrier Transicold APX control system (Refer to Section 2.5). Once the
system is set at the desired temperature, the unit will operate automatically to maintain the desired temperature
within very close limits.
Standard equipment includes an auto start-stop feature. This feature provides automatic cycling of the compressor,
which in turn offers an energy efficient alternative to continuous operation with control of temperature by alternate
cooling and heating of the supply air (evaporator outlet air).
The unit can be described as having two major sections:
• The condensing section (Figure 2.1)
• The evaporator section (Figure 2.2)
• The control system
