Water-cooled chillers
DESCRIPTION
XTRACONNECT2 is equipped as standard with an RS485 serial port that allows many remote management, supervision and diagnostics possibilities over a communication bus. Several contacts are available as standard for controlling HYDROCIAT remotely over a wired connection: Automatic operation control: the machine shuts off when the contact opens. Setpoint 1/setpoint 2: a second cooling setpoint is activated when this contact closes (e.g. energy storage mode) Heating/cooling mode selection: this input is used to switch between operating modes. Contact closed = heating mode Contact open = cooling mode Setpoint adjustable via 4-20 mA signal: this input is used to adjust the heating or cooling setpoint Compressor load shedding: closing the relevant contact(s) turns off one or more compressors and thus lowers the machine’s electricity or refrigerant consumption Water pump 1 and 2 control: these outputs control the contactors of one or two water pumps Fault signalling: this contact indicates that a major fault has occurred and caused one or more refrigerating circuits to turn off Energy meter fitted in the machine’s electrical cabinet measures the following: - voltage across each phase - total input current - total input power - total electricity consumption The meter also enables the machine’s maximum electricity consumption to be kept below a limit that can be set in the controller. This limitation can be activated: - at all times - by an on/off input - over a Modbus BMS network
