t and Installation
Inside the electrical panel there are two electronic boards: one for the management of the high-pressure part
of the equipment (i.e., heat recovery, gas cooler, back pressure valve, and gas flash valve) and one for the
management of rotary compressors.
Normally, the display on the electrical panel is connected (via a 6-pole telephone cable) to the management
controller of the high-pressure part (pRack application). Therefore, to turn the software of the second controller
ON, it is necessary to disconnect the telephone cable connected to the display and to attach the second
telephone cable located nearby. This procedure provides accessibility to the second controller.
• Turn the pRack CO2 application ON.
Follow these steps for this application:
