INTRODUCTION INTRODUCTION The Carrier Transicold PrimeLINE models 69NT40-561-200 to 299 and 69NT40-561-500 to 599 are units of light- weight aluminum frame construction, designed to be bolted on to the front of a container and serve as the con- tainer’s front wall. Forklift pockets are provided for unit installation and removal.
2.4.4 Compressor The unit is fitted with either an R-134a or an R-513A scroll compressor equipped with suction and discharge ser- vice connections. To identify an R-513A-ready compressor in the field, a green dot is located on the top of the com- pressor on the DUV fitting.
2.5.8 Autotransformer An autotransformer may be provided to allow operation on 190/230, 3-phase, 50/60 Hz power. The autotrans- former 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.
NOTE Repaired controllers are NOT to be used for warranty repairs; only full OEM Re-manufactured control- lers 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. 2.5.21 Condenser Grille Condenser grilles are direct bolted.
SECTION 3 DESCRIPTION GENERAL DESCRIPTION 3.1.1 Refrigeration Unit - Front Section The unit is designed so that the majority of the components are accessible from the front (see Figure 3.1). The unit model number, serial number and parts identification number can be found on the unit nameplate on the back wall of the condenser section.
3.1.2 Fresh Air Makeup Vent The function of the upper or lower makeup air vent is to provide ventilation for commodities that require fresh air circulation. A manually operated venting system is located in the upper left access panel. 3.1.3 Evaporator Section The evaporator section is shown in Figure...
3.1.4 Compressor Section The compressor section (see Figure 3.4) includes the compressor, digital unloader valve (DUV), high pressure switch, discharge pressure transducer (DPT), evaporator pressure transducer (EPT) and the suction pressure transducer (SPT). The supply temperature sensor and supply recorder sensor are located to the left of the com- pressor.
3.1.5 Air-Cooled Condenser Section The air-cooled condenser section (see Figure 3.5) consists of the condenser fan, condenser coil, receiver, liquid line service valve, filter drier, fusible plug, economizer, economizer expansion valve, economizer solenoid valve (ESV), and sight glass/moisture indicator. The condenser fan pulls air from around the coil and discharges it hori- zontally through the condenser fan grille.
3.1.6 Water-Cooled Condenser Section The unit may contain a water-cooled condenser (wcc) installed as an option. When operating on the water-cooled condenser, the condenser fan is deactivated by a water pressure switch or condenser fan switch. There are two types of water-cooled condensers available and both are described below. a.
b. Brazed Plate Water-Cooled Condenser The brazed plate water-cooled condenser section (see Figure 3.7) consists of the brazed plate water-cooled con- denser, water couplings, a water pressure switch and a fusible plug. The receiver is retained in this configuration and the brazed plate heat exchanger is placed between the air-cooled condenser and the receiver. Figure 3.7 Brazed Plate Water-Cooled Condenser 1.
3.1.7 Control Box Section The control box (see Figure 3.8) includes: the manual operation switches, circuit breaker (CB-1), compressor, fan and heater contactors, control power transformer, fuses, keypad, display module, current sensor module, controller module and the communications interface module.

REFRIGERATION CIRCUIT 3.5.1 Standard Operation Starting at the compressor, (see Figure 3.9) the suction gas is compressed to a higher pressure and temperature. The refrigerant gas flows through the discharge line and continues into the air-cooled condenser. When operating with the air-cooled condenser active, air flowing across the coil fins and tubes cools the gas to saturation tempera- ture.
SECTION 4 MICROPROCESSOR TEMPERATURE CONTROL MICROPROCESSOR SYSTEM The temperature control Micro-Link 3 microprocessor system (see Figure 4.1) consists of a keypad, display mod- ule, control module (controller) and interconnecting wiring. The controller houses the temperature control software and the DataCORDER software. The temperature control software functions to operate the unit components as required to provide the desired cargo temperature and humidity.

The control module (see Figure 4.4) is fitted with test points, harness connectors and a software card program- ming port. Figure 4.4 Control Module EN12830 CONTROLLER With CARRIER REV 5147 YYWW: 1035 12-00579-00 Micro-Link3 S/N: 0491162 DataCORDER 59980 T B C1 1.
4.2.1 Configuration Software (CnF Variables) Configuration software is a variable listing of the components available for use by the operational software. This software is factory installed in accordance with the equipment fitted and options listed on the original purchase order. Changes to the configuration software are required only when a new controller has been installed or a phys- ical change has been made to the unit such as the addition or removal of an option.
4.3.4 Perishable Pulldown When the system is in Perishable Pulldown mode, the highest priority is given to bringing the container down to setpoint. When cooling from a temperature that is more than 2.5°C (4.5°F) above setpoint, the system will be in Perishable Pulldown mode in economized operation.
4.3.8 Perishable Dehumidification Dehumidification is provided to reduce the humidity levels inside the container. The dehumidification setpoint range is from 50% to 95%. Dehumidification is activated when a humidity value is set at Cd33. The yellow SUPPLY LED will flash ON and OFF every second to indicate that Dehumidification is active. Once Dehumidification is active and the following conditions are satisfied, the controller will activate the heat relay to begin Dehumidification.
4.3.10 Perishable Economy Economy Fan mode is an extension of the Perishable mode, and is provided for power saving purposes. Economy Fan mode is activated when Cd34 (also used for Frozen Economy mode) is set to “ON.” Economy Fan mode is used in the transportation of temperature-tolerant cargo or non-respiration items which do not require high airflow for removing respiration heat.
d. When unloaded cooling starts, EEV control will transition from a full cool superheat setpoint to a lower mod- ulated cool superheat setpoint. Once unloading starts, the EEV controls evaporator superheat based on the system duty cycle where instantaneous superheat will vary. e.
4.3.13 Perishable Mode - Trim Heat If the system capacity has been decreased to the lowest allowable capacity and conditions exist that warrant max- imum temperature stability the controller will pulse the HR relay to energize the evaporator heaters in sequence with the compressor digital signal.
4.3.17 Frozen “Heat” Mode If the temperature drops 10°C (18°F) below setpoint, the unit will transition to the Frozen “Heating” mode. The evaporator fans are brought to high speed, and the heat from the fans is circulated through the container. The unit will transition back to Frozen Steady State when the temperature rises back to the transition point.
4.3.20 Defrost Defrost is initiated to remove ice buildup from the evaporator coil which can obstruct air flow and reduce the cooling capacity of the unit. The defrost cycle may consist of up to three distinct operations depending upon the reason for the defrost or model number configuration.
3. Probe Check: If defrost is initiated due to Probe Check immediately following the defrost cycle the evapora- tion fans are started and run for eight minutes to stabilize the temperature throughout the container. A probe check comparison is carried out at the end of the eight minute period if any sensor is found out of calibration. At this time its alarm set is no longer used for control/reorder purposes.
Defrost Timer If CnF23 is configured to “SAv” (save), then the value of the defrost interval timer will be saved at power down and restored at power up. This option prevents short power interruptions from resetting an almost expired defrost inter- val, and possibly delaying a needed defrost cycle.
4.3.29 Condenser Fan Override When CnF17 (Discharge Temperature Sensor) is set to “In” and CnF48 (Condenser Fan Switch Override) is set to “On”, the condenser fan switch override logic is activated. If condenser cooling water pressure is sufficient to open the water pressure switch (de-energizing the condenser fan) when water flow or pressure conditions are not main- taining discharge temperature, the logic will energize the condenser fan as follows: 1.
4.7.1 Description Carrier Transicold “DataCORDER” software is integrated into the controller and serves to eliminate the tempera- ture recorder and paper chart. DataCORDER functions may be accessed by keypad selections and viewed on the display module. The unit is also fitted with interrogation connections (see Figure 4.1) which may be used with the...

T107, T108, and T109 of the USDA Treatment Manual. In response to the demand to replace fumigation with this environmentally sound process, Carrier has integrated Cold Treatment capability into its microprocessor system. These units have the ability to maintain supply air tem- perature within one quarter degree Celsius of set point and record minute changes in product temperature within the DataCORDER memory, thus meeting USDA criteria.
a. USDA Recording A special type of recording is used for USDA cold treatment purposes. Cold treatment recording requires three remote temperature probes be placed at prescribed locations in the cargo. Provision is made to con- nect these probes to the DataCORDER via receptacles located at the rear left-hand side of the unit. Four or five receptacles are provided.

e. At the load side of the heater contactor, check the insulation resistance to ground. If readings are > 1 Mohm, then the heaters are operating properly and no action is needed. If readings are < 1 Mohm, then the faulty heater needs to be identified. Proceed to step 3 for units with a heater access panel or step 4 for units without a heater access panel.
Reconnect all wiring using new splices and heat shrink where needed. The heat shrink MUST have a 'melt-able' liner to ensure that the connections are properly sealed when shrunk. This can be seen as a 'Ring' of melt liner pushed from under the heat shrink at each end of the shrink tube. NOTE Failure to use melt liner heat shrink allows moisture to 'wick' up under the heat shrink and cause a leakage path.
Analysis by Carrier Transicold environmental specialists have identified the white powder as consisting predomi- nantly of aluminum oxide. Aluminum oxide is a coarse crystalline deposit most likely the result of surface corrosion on the aluminum parts within the container.
