MultiFlex PAK-Refrigeration PACK Controller
The PAK is a distributed pack controller that controls compressors and condenser fans. The PAK can control up to 16 compressors, controlled in up to 8 compressor groups.
The PAK can control up to 4 condenser fan groups containing up to 8 total condenser fans. The PAK condenser control strategy is sequential TD control with setpoint/deadband using ON and OFF delays. The PAK supports use of both single-speed fan stages and VS fans.
The MultiFlex PAK boards consist of two circuit boards: a bottom layer with 16 combination digital/analog inputs, and a plug-in top layer which contains a combination of 8 relay outputs and 4 analog DC voltage outputs, which can be used as digital or analog outputs.
The communication interface is RS485 I/O using the Standard Extended Address Form for Copeland. Currently, the PAK is designed to interface with the Copeland E2 RX controller, and the previous generation refrigeration controller, the Einstein RX.
