PrimeLINE ONE™ Container

At the Asia Intermodal show, Carrier Transicold introduced a new refrigeration model named the PrimeLINE ONE™ refrigerated container.

The new model is a refrigerated shipping container developed through a joint initiative of Carrier Transicold and Singamas Container Holdings Ltd., a manufacturer of shipping containers.

The PrimeLINE ONE container (Model Number 69NT40-565-250, -500) provides an alternative to bolting a com­plete refrigeration system onto the front end of the box. The refrigeration system components are built at the Car­rier Transicold factory in Singapore and shipped to a new Carrier Transicold factory located adjacent to the Singamas container factory in Qingdao, China.

The system refrigeration components are assembled on-site onto the welded front wall of a specially designed con­tainer, within the Carrier Transicold factory. The unit is commissioned right at the factory.

Key PrimeLINE ONE Container Features:

1.Proven performance of the PrimeLINE® refrigeration system. All of the components, controller and control software are identical to the PrimeLINE system, helping to ensure proven performance.

2.Easy maintenance and repairs. All of the components, controller and control software are interchangeable with existing parts of the PrimeLINE system. No special parts are required.

Battery Charger Troubleshooting (30-00460-06)

RG Gensets with PIDs greater than RG2059 (Tier 4), RG1862 (Tier 4i) and UG Gensets greater than UG2019 (Tier 4), UG1820 (Tier 4i) have a new battery charger, part number 30-00460-06. The -06 charger looks similar to the -04 and -05 but are not interchangeable due to internal components. The -06 can be used as a replacement for the -05 with some modification to the plug, but the -05 should not be used as a replacement for the -06.

Tools Required:

•DC Amp Meter / Multimeter (DC Voltage)

Procedure:

1.Follow local lockout / tagout procedures when troubleshooting.

2.Connect a DC current clamp to the Red (+) wire on the DC output harness to the battery.

You may need to slide back or carefully cut back the black tubing covering sleeve to get access to the red wire on the fitting of the current clamp.

3.With the Genset unit off, hold the air intake heater switch on for 30 seconds.

4.Turn the Genset unit on and note the current draw on the current clamp.

5.After troubleshooting is complete, tape the tubing back over the wires.

6.If it is determined that the battery charger is bad, it is important to document the amperage and voltage find­ings on the RMA (return material authorization) to assist with future analysis of the failed part.

NaturaLINE® CO2 Refrigerant

Carrier Transicold’s NaturaLINE® container refrigeration unit model 69NT-40-601 uses CO2 refrigerant commonly known as R-744. The R-744 used in the NaturaLINE product conforms to Air-Conditioning, Heating and Refrigera­tion Institute (AHRI) standard 700. By standardizing the purity levels of R-744, this reduces the amount of impuri­ties allowed that may be detrimental to the refrigeration system.

As there are different purity levels of CO2, it is recommended that when purchasing refrigerant, you also receive a Certificate of Conformance.

Tier 4 Genset Voltage Controller

The Voltage Controller (VC), part number 12-00707-03, is used to regulate voltage in order to keep the generator output within ISO limits using the Primary and Boost contactors.

The voltage controller (VC) has one green indicator light and one yellow / amber indicator light along with 4 input fuses. The voltage controller fuses, VCF4 and VCF5 carry the power to the controller, and fuses VCF1 and VCF2 sense the demand on the generator adjusting output voltage accordingly. The green LED light is a signal that the voltage controller is receiving power at voltage controller plug VCA1 and VCA2 on the connector. The yellow / amber light will flash once per second if operating normally. Any other flashing sequence is an indication of a potential problem.

Below is the schematic layout of the inputs and outputs of the voltage controller, along with a general guide to be used in troubleshooting the controller. Follow local lockout / tagout procedures when troubleshooting.

Automatic Cold Treatment (ACT) Cd51

Cold Treatment has been employed as an effective post-harvest method for the control of Mediterranean and certain other tropical fruit flies. Exposing infested fruit to temperatures of 2.2°C (3.6°F) or below for specific time periods results in the mortality of various life stages for this group of insects.

Automated Cold Treatment (ACT) in the Carrier Transicold unit is a method to simplify the task of completing cold treatment by automating the process of changing the setpoints. ACT is set up through Code Selection Cd51. Refer to Function Code table in operations and service manual for Cd51 menu processing and displays.

Procedure to Set ACT:

1.Enter the required cargo setpoint. It must be lower than the treatment temperature that will be discussed in step 5.

2.Press the CODE SELECT key.

3.Use the Arrow keys to scroll to Cd51, and then press the ENTER key.

4."ACt" is now displayed in the left display and the right will display "Off". Use the Arrow keys to bring up "On" in the right display and press the ENTER key.

5.“trEAt" is now displayed in the left display and the right will be flashing the last setting (shown as XX.X°C). Use the Arrow keys to select the desired cold treatment setpoint and press the ENTER key.

"trEAt" is the maximum value that the USDA probes need to remain below, to pass the Cold Treatment protocol. For instance, if the treat value is set at 35.0°F (1.7°C) then the USDA probe temperatures must remain below 35.0°F (1.7°C) to pass.

6."dAyS" is now displayed in the left display and the right will be flashing. Use the Arrow keys to select the desired days for cold treatment and press the ENTER key.

7."ProbE" is now displayed in the left display and the right will display the probe numbers that are connected. Press the ENTER key. For instance, if "1234" is displayed, then all four of the probes are connected.

8."SPnEW" is now displayed in the left display and the right will be flashing. Use the Arrow keys to select the desired setpoint after the cold treatment process has successfully completed and press the ENTER key. This would be the final temperature prior to the delivery of the cargo.

9.Cd51 is now displayed in the left display and the right will display days / hours remaining in cold treatment.

Once the cold treatment process has been initiated, setpoint change via the keypad is disabled.

The unit will start to countdown once all detected USDA probes have reached the cold treatment temperature in step 5 above. The cold treatment process will continue until the number of days specified in step 6 is reached. During operation, Cd51 will show the number of days and hours remaining in the cold treatment.

While the unit is operating in ACT mode, the left hand display will alternate between "COLd" and setpoint. The right hand display will alternate between "trEAt" and the cargo temperature. Once the treatment time has been com­pleted, the setpoint temperature will increase to the "SPnEW" setting chosen in step 8.

When the cold treatment process is complete, the "SPnEW" setpoint will be displayed in the left hand display and cargo temperature in the right hand display, alternating with "COLd" "Done". "COLd" "Done" will continue to alter­nate with the setpoint and cargo temperature until ACT is turned off.

ACT can be manually turned off by selecting Cd51, scrolling to "Off" and pressing the ENTER key.

ACT will be automatically turned off with a TripStart, or if a Pretrip is initiated.

Automatic Setpoint Change (ASC/ Cd53) and ACT (Cd51) will not work simultaneously. Setting one will deactivate the other.

ContainerLINK™ App Update

The ContainerLINK™ mobile app, which was released in May of this year, puts a wealth of technical and trouble­shooting information into the hands of refrigeration technicians. Available free on both iOS and Android devices, it offers interactive resources, including service manuals with instructional videos, an alarm code lookup function, conversion tools and warranty information for units being serviced.

The app contains a "Mobile Manuals" menu that provides access to mobile-optimized service manuals. These manuals include all text and visuals found in the standard printed equipment manuals, with added benefits of search ability, pinch-to-zoom for closer study of detailed schematics and embedded videos that show maintenance procedures.

Mobile-optimized versions require internet access for viewing. In the event that a technician needs off-line access to a manual, the app provides links to download and save the PDF versions of all manuals. PDF manuals are help­ful in environments where there may not be cellular or Wi-Fi connections and useful for ship crews that need to repair a refrigeration unit while a container is at sea.

In addition to PDF service manuals, the app now provides access to current and archived issues of the TechLINE newsletter in PDF format. These are also accessible from the Mobile Manuals menu.

To access PDF service manuals from the Mobile Manuals menu:

Over the last few months, there have been a number of incidents with returned parts particularly compressors, microprocessors and motors. For diagnosing any failed part, it is important that packaging is correct and adequate when returning any part, preventing damage not associated to the true failure. The easiest way to achieve this is to establish a standard practice of reusing the original packaging for the return part.

Compressors - It is recommended that compressors are unbolted from the original base pallet and that all packag­ing is retained and used to prepare the failed compressor for return. Install seal plugs into refrigerant connections and bolt the compressor back onto the base pallet. Compressors must NEVER be shipped laying down in a plastic bag!

Microprocessors - Electronic parts should always be kept in an anti-static bag to prevent static damage to internal parts and then placed back into the original external packaging. They have an internal lithium battery, and must be shipped with the 'Lithium battery warning' label, clearly visible.

Motors - Motors should be packaged in the original packaging, INCLUDING, the polystyrene supports, which hold the motor and prevent it from rolling damaging the shipping box

Trip Start Definition

A Trip Start is an event posted in the DataCorder. Typically this event is posted to notify the customer when a trip has been started. It also places a marker in the DataCorder, so the user can download the information for one trip. When a Trip Start is set, the unit may be set back to the units / customers default settings (i.e. defrost to AUTO, ASC to OFF, etc.).

A trip start event can be posted in 4 ways:

1.User manually enters a Trip Start via the keypad.

2.A successful AUTO PTI has been run.

•If model configuration variable 42 is 'out' a trip start event will not occur with an AUTO PTI.

3.A remote command is sent through the RMM device (if equipped).

4.On power up, if the unit has been off for greater than 7 days. The 7 days was selected based on a unit that has been off for 7 days. With this the assumption is that it has no cargo loaded and will be starting a new trip.

For specific details on the model configuration / default settings, contact your Regional Field Service Engineering Manager.
