2.5 UPPER FRESH AIR MAKEUP VENT The purpose of the fresh air makeup vent is to provide ventilation for commodities that require fresh air circulation. The vent must be closed when transporting frozen foods or controlled atmosphere loads. Air exchange depends on static pressure differential, which will vary depending on the container and how the container is loaded. 2.7 REFRIGERATION CIRCUIT WITH RECEIVER Starting at the compressor, the suction gas is compressed to a higher temperature and pressure.

When operating with the air-cooled condenser, the gas flows through the discharge service valve into the pressure regulator valve that is normally open. The pressure regulator valve restricts the flow of refrigerant to maintain a minimum discharge pressure of 5 kg/cm@ (70 psig). Suction Service Valve 2. Discharge Service Valve 3.

3.1.3 General Layout of the Controller Section The Micro-Link 2i Controller/DataCORDER consists of a key pad, display module and Controller module. Connectors are used to attach the wiring of the unit to the Controller module.

The Controller module is designed to permit ease of installation and removal. All control functions are accessed by key pad selections and viewed on the display module which are designed for optimum user friendliness and convenience. The display module (see Figure 3-2) is mounted at a 20 degree downward tilt to aid in visibility. The display module consists of: a. Two 25mm (1 inch) high, five digit LCD displays which are easily viewed in direct sunlight and backlighted for superior low-light visibility. 3.1.4 Controller Function Codes There are thirty-nine functions which the operator may access to examine the operating status of the unit. To access these functions, perform the following steps: Press the CODE SELECT key, then press an arrow key until the left window displays the desired code number Table 3-3.

CODE TITLE Inapplicable Functions Display - - - - -Condenser pressure is displayed using a pressure transducer. Pressure is displayed in units of psig when code 28 is set to F and units of bars when Condenser Pressure Cd13 function code Cd28 is set to C. CODE TITLE Function codes Cd27 through Cd37 are user-selectable functions.

The operator can change the value of these functions to meet the operational needs of the container. The defrost interval is the time interval between defrost cycles. Five selectable values are available: 3, 6, 9, 12 or 24 hours. The factory default value is 12 hours. The time interval of the first defrost will not begin counting down until defrost termination sensor (DTS) is below 10C (50F).

CODE TITLE Inapplicable Functions Display - - - - -The current limit is the maximum current demand allowed on any phase at any time. Limiting the unit’s current (amperage) reduces the load on the main power Current Limit and lowers the compressor discharge pressure. CODE TITLE This code is only applicable to units without a DataCORDER, that are configured Secondary Return to have four probes. If this is true, it will then display the current secondary return Cd39 Air Temperature air temperature.If the unit is configured with a DataCORDER, the Controller (Optional) function code Cd39 will display “-,”.

Controller Alarm Indications CODE TITLE Alarm 11 is triggered by the opening of the internal protector for evaporator fan Evaporator Fan motor #1. This alarm will disable the probe check portion of defrost and the probe AL11 Motor 1 Safety diagnostic logic. CODE TITLE Alarm 53 is caused by the nicad battery pack being too low of a charge for battery-backed recording. NiCad Battery Pack AL53 Failure Alarm 54 is activated by an invalid primary supply sensor reading that is sensed outside the range of -50 to +70C (-58F to +158F) or if the probe check logic has determined there is a fault with this sensor. CODE TITLE Alarm 63 is triggered by the current limiting system.

If the compressor is ON and current limiting procedures cannot maintain a current level below the user selected limit, the current limit alarm is activated.This alarm is a display alarm and AL63 Current Over Limit is inactivated by power cycling the unit, changing the current limit via the code select Cd32, or if the suction modulation valve (SMV) is allowed to open to 100%. 3.1.6 Condenser Pressure Control (CPC) A pressure control system has been incorporated by means of a condenser pressure transducer (CPT) and condenser pressure control (CPC) logic to maintain discharge pressures above temperatures. In order for the CPC logic to be enabled, the following conditions must be met: CPC configuration variable set to “In”. modulation valve (SMV) and suction solenoid valve (SSV) with the compressor energized. When pulling down from a control temperature that is more than 5C (9F) above set point, both valves will be open to reduce the pulldown time unless suction solenoid override or current limiting is activated.

out-of-range or compressor shutdown condition, the heat relay is de-energized immediately. The out-of-range timer is provided to allow the heaters to remain energized during a temporary out-of-range condition. If the control probe temperature remains outside of the user selected in-range setting for more than five minutes, the heaters will be de-energized to allow the system to recover. 3.1.7.2 Frozen Range Below - -10C (+14F), or - -5C (+23F) Optionally For set points below - -10C (+14F), or - -5C (+23F) optionally, the Controller maintains RETURN air at the set point temperature using the following modes of operation: a. the VENT mode is selected on the CA Controller. The user must scroll through the selection by pressing the UP ARROW or DOWN ARROW keys, then pressing the ENTER key when the selection is made. While the tests are being executed, the user can terminate the pre-trip mode by holding the PRE-TRIP key.

Auto Test Operation From Serial Communications Pre-trip may also be initiated via communications. The operation is the same as for the Auto Test mode described above except that should a test fail, the pre-trip mode will automatically terminate. When initiated via communications, a test may not be interrupted with an arrow key, but the pre-trip mode can be terminated with the PRE-TRIP key. CODE TITLE Setup: The high speed Evaporator Fan is turned off, a current draw test is done High Speed after 10 seconds. Evaporator Fan P4-1 Pass/Fail Criteria: Passes if change in current draw is within the range Motors Off specified. Fails if AL11 or AL12 activates during test.

Setup: The High Speed Evaporator Fan is turned on and run for eight minutes, with all other outputs de-energized. CODE TITLE Setup: The compressor is started. If it is the first compressor start, the compressor reliability enhancement logic (CREL) is executed, running a current draw test with the additional outputs (if installed) in the following states: High Speed Component Compressor Tests P6-H P6-H. CODE TITLE Starting with test P7-0 through test P10, these tests are only included with the “Auto2” (Optional) selection menu.

(Refer to section 3.2.1.) Setup: When the unit is running, the condenser fan is de-energized, and a 15 minute timer is started. The right display shows discharge pressure if equipped with the discharge pressure transducer (DPT), or condenser pressure if equipped with a condenser pressure transducer (CPT), or discharge pressure if equipped with either a discharge pressure transducer (DPT) or a condenser. CODE TITLE Requirements: Control temperature must be at least 60F. Setup: The set point is changed to 32F, and a 180 minute timer is started. The left display will read “P8-1,” the right display will show the supply air temperature.

Perishable Mode P8-1 The unit will then start to pull down the container temperature to the 32F set. 3.3 INTEGRATED DATACORDER (OPTIONAL) 3.3.1 Brief Description Carrier Transicold has developed a recorder, which we have termed the “DataCORDER,” and is integrated into a module with the Controller.

If container is empty, check inside for the following: 1.

Check channels or “T” bars on floor for cleanliness. Channels must be free of debris for proper air circulation. 4.2 STARTING AND STOPPING INSTRUCTIONS CAUTION Make sure that the unit circuit breaker(s) (CB-1 & CB-2) and the start-stop switch (ST) are in the OFF position before connecting to any electrical power source. Starting the Unit NOTE The evaporator fans will always start in high speed regardless of set point and will switch to low speed after approximately 20 to 30 seconds if the set point is below - -10C (+14F),. If AL55 is active, meaning that the DataCORDER (DC) functionality is no longer active (DC configuration variable off), the Controller will act as a four probe configured system during probe checks. The only differences will be that the Controller Function Codes Cd38 and Cd39 will become enabled thus allowing access to the secondary probe readings since the DC functions, codes and alarms have become deactivated. When the air temperature decreases to a predetermined tolerance above set point, relay TI energizes and the in-range light is illuminated.

(Refer to section 3.1.4, Code 30.) If the air temperature continues to fall, modulating cooling starts at approximately 2.5C (4.5F) above set point.
