A brief description of the topics in this newsletter is provided below.
At the Intermodal Europe 2011 show in Hamburg, Carrier Transicold introduced the product design for the NaturaLINE™ unit, the world’s first natural refrigerant container unit using CO2 (R-744).
PrimeLINE® Pressure Transducer Testing
The Carrier PrimeLINE® unit model 69NT40-561-XXX is fitted with an Electronic Expansion Valve (EEV). The valve is controlled via outputs from the Micro-Link® 3 controller, which takes inputs from the Evaporator Pressure Transducer (EPT) that is mounted on the suction line.
Carrier Transicold container equipment uses R134a refrigerant, conforming to Air-Conditioning, Heating and Refrigeration Institute (AHRI) standard 700. While this standard specifies 99.5% R134a purity, the remaining 0.5% of other refrigerants may ONLY consist of the standard traditional refrigerants such as R12, R22 and refrigerants that make up the recognized R4xx blends.
Carrier Transicold has implemented an improvement to the water cooled condenser (WCC) sight glass repair kit (Part # 74-66640-00) using Loctite cord 55 and sealer 290 as detailed below.
dAL86 / dAL87 (Real Time Clock Battery Low / Real Time Clock Failure)
A DataCorder alarm 86 (dAL86) is a warning sign that the battery that powers the real time clock on the Micro-Link® 2i or Micro-Link® 3 controller and parameter/temporary data storage memory on the Micro-Link 2i controller requires replacement. An immediate action should therefore be taken to mitigate the risk of data loss or incorrect controller operation.
When downloading a Micro-Link® 2i or MicroLink 3 controller using a DataBANK® card, priority is given to the DataBANK software for the downloading of data from the unit.
Carrier Transicold uses a toll free technical support line via AT&T 800USA direct. To use this number, the caller should contact the USA direct number in their region and provide them the 800 number (800-668-6283).
Programming the Micro-Link® 2i controlled atmosphere controller has typically been performed using the HEX flash memory cards. The device used to program these cards has become increasingly more difficult to purchase. Therefore, beginning with software version 3114, you will have the ability to use the PCMCIA cards.
