Section 2
The Carrier Transicold PrimeLINE models 69NT40-561-200 to 299 and 69NT40-561-500 to 599 are units of lightweight aluminum frame construction, designed to be bolted on to the front of a container and serve as the container’s front wall. Forklift pockets are provided for unit installation and removal.
The Carrier Transicold PrimeLINE ONE™ models 69NT40-565-200 to 299 and 69NT40-565-500 to 599 are units of lightweight aluminum frame construction, designed to be directly installed on-site onto a welded front wall of a container.
PrimeLINE units are self-contained, all electric units, which include cooling and heating systems to provide precise temperature control. The units are supplied with a complete charge of refrigerant and compressor lubricating oil, and are ready for operation upon installation.
The base unit operates on nominal 380/460 volt, 3-phase, 50/60 hertz (Hz) power. An optional autotransformer may be fitted to allow operation on nominal 190/230, 3-phase, 50/60 Hz power. Control system power is provided by a transformer which steps the supply power down to 18 and 24 volts, single phase.
The controller is a Carrier Transicold Micro-Link 3 microprocessor. The controller operates automatically to select cooling, holding or heating as required to maintain the desired set point temperature within very close limits. The unit may also be equipped with an electronic temperature recorder. The controller has a keypad and display for viewing or changing operating parameters. The display is also equipped with lights to indicate various modes of operation.
PrimeLINE models 69NT40-561-200 to 299 and PrimeLINE ONE™ models 69NT40-565-200 to 299 are units designed to only be charged with R-134a refrigerant.
PrimeLINE models 69NT40-561-500 to 599 and PrimeLINE ONE™ models 69NT40-565-500 to 599 are R-513A-ready units. They are supplied with a complete charge of R-134a refrigerant. But, they are capable of being field converted to R-513A refrigerant at a later date as requested by the unit owner. R-513A is an azeotrope blend containing R-1234yf and R-134a. All information in this manual pertaining to R-513A is only applicable to 561-500 to 599 or 565-500 to 599 model units that have either been converted or are being converted to R-513A.
To convert a R-513A-ready unit to R-513A refrigerant, refer to the procedure in Section 7.8 of the Service chapter.
2.3Configuration Identification
Unit identification information is provided on a unit nameplate (see Figure 3.1) located on the back wall of the condenser section. The nameplate provides the unit model number, serial number and parts identification number (PID). The model number identifies the overall unit configuration, while the PID number provides information on specific optional equipment, factory provisioned to allow for field installation of optional equipment and differences in detailed parts.
Units are equipped with an aluminum control box, and may be fitted with a lockable door.
The unit is fitted with suction and discharge refrigerant temperature sensors. The sensor readings may be viewed on the controller display.
The unit is fitted with an evaporator, suction, and discharge pressure transducers. The transducer readings may be viewed on the controller display.
The unit is fitted with either an R-134a or an R-513A scroll compressor equipped with suction and discharge service connections. To identify an R-513A-ready compressor in the field, a green dot is located on the top of the compressor on the DUV fitting.
Units may be fitted either with a “C” shape condenser coil, or a “U” shape micro-channel heat exchanger (MCHE) condenser coil.
The evaporator section is equipped with an electronic expansion valve (EEV).
Units are equipped with three-phase evaporator fan motors. Opening of an evaporator fan internal protector will shut down the unit.
Each unit is equipped with a tethered set of wiring schematics and wiring diagram plates. The plate sets are ordered using a seven-digit base part number and a two-digit dash number.
Various options may be factory or field equipped to the base unit. These options are described in the following sub-paragraphs.
The refrigeration controller may be fitted with standard replaceable batteries or a rechargeable battery pack. Rechargeable battery packs may be fitted in the standard location or in a secure location.
The unit may be fitted with a humidity sensor. This sensor allows setting of a humidity set point in the controller. In dehumidification mode, the controller will operate to reduce internal container moisture level.
The unit may be supplied with fittings for additional temperature probes, which allow recording of USDA Cold Treatment data by the integral DataCORDER function of the Micro-Link refrigeration controller.
Units that use the DataCORDER function are fitted with interrogator receptacles for connection of equipment to download the recorded data. Two receptacles may be fitted; one is accessible from the front of the container and the other is mounted inside the container (with the USDA receptacles).
The unit may be fitted with a remote monitoring receptacle. This item allows connection of remote indicators for COOL, DEFROST and IN RANGE. Unless otherwise indicated, the receptacle is mounted at the control box location.
2.5.6Communications Interface Module
The unit may be fitted with a communications interface module. The communications interface module is a slave module which allows communication with a master central monitoring station. The module will respond to communication and return information over the main power line. Refer to the ship master system technical manual for further information.
An autotransformer may be provided to allow operation on 190/230, 3-phase, 50/60 Hz power. The autotransformer raises the supply voltage to the nominal 380/460 volt power required by the base unit. The autotransformer may also be fitted with an individual circuit breaker for the 230 volt power.
If the unit is equipped with an autotransformer and communications module, the autotransformer will be fitted with a transformer bridge unit (TBU) to assist in communications.
Rain gutters may be fitted over the control box and recorder section to divert rain away from the controls.
The unit may be equipped with handles to facilitate access to stacked containers. These fixed handles are located on either side of the unit.
The unit may be fitted with ports in the front of the frame for insertion of a thermometer to measure supply and/or return air temperature. If fitted, the port(s) will require a cap and chain.
The refrigeration system may be provisioned for a water-cooled condenser. The condenser is constructed using copper nickel tube for sea water applications. Refer to Section 3.1.4 for a more detailed description of the water-cooled condenser.
Aluminum back panels may have access doors and/or hinge mounting.
Various power cable and plug designs are available for the main 460 volt supply. The plug options tailor the cables to each customer’s requirements.
Units equipped with an autotransformer require an additional power cable for connection to the 230 volt source. Various power cable and plug designs are available. The plug options tailor the cables to each customer’s requirements.
Various designs are available for storage of the power cables. These options are variations of the compressor section cable guard.
2.5.16Upper Air (Fresh Air Make Up)
The unit may be fitted with an upper fresh air makeup assembly. The fresh air makeup assembly is available with a vent positioning sensor (VPS) and may also be fitted with screens.
2.5.17Lower Air (Fresh Air Make Up)
The unit may be fitted with a lower fresh air makeup assembly. The fresh air makeup assembly is available with a vent positioning sensor (VPS) and may also be fitted with screens.
Safety Instruction and Function Code listing labels differ depending on the options installed. Labels available with additional languages are listed in the parts list.
Two replacement controllers are available:
1.Re-manufactured - Controller is equivalent of a new OEM controller, supplied with a 12-month warranty.
2.Repaired - Controller has had previous faults repaired and is upgraded with the latest software.
Repaired controllers are NOT to be used for warranty repairs; only full OEM Re-manufactured controllers are to be used.
Controllers will be factory-equipped with the latest version of operational software, but will NOT be configured for a specific model number and will need to be configured at the time of installation or sale.
Condenser grilles are direct bolted.
The optional Emergency Bypass switch (EB) functions to bypass the controller in the event of controller failure.
