  • Page 6: General Information

    CAUTION: THERE IS NO GENERAL RULE for establishing the appropriate number of sensors and their location for each application. Therefore, the guidelines described below are intended as support for installers, and not as rules in their own right. SAMON accepts no liability for the installation of the gas detectors.
  • Page 7 3.2.4 Chillers Measuring leaks on outdoor chillers is generally more difficult, given the highly variable air flow. Generally, it is recommended to install the gas detectors near the compressor, as this is the place where refrigerant leaks are most likely to occur. In particular, check if it is possible to install the gas detector inside the closed unit near the compressor, where gas is more likely to stagnate.
  • Page 8 • Open the cover of the GLACIÄR MIDI, fit the cable glands and make the required electrical connections. The plug-in terminals can be removed from the device to facilitate wiring. • Power the device on and complete the settings using the rotary switch, as described in the following paragraphs, or using the app, as described below or through the Modbus connection.

  • Page 12 4.3 Setup of the device using the rotary switch The rotary switch (R1) is located inside the device, on the electronic board . The basic configuration can be performed using the rotary switch, following the instructions described below. To complete the configuration, a digital multimeter is required, with the test leads connected to connector J6. In this way, the tester will show a voltage between 0 and 10 Volts, indicating the value selected by the rotary switch.

  • Page 16: Alarm Management

    4.5 Alarm management The alarms are activated when the set thresholds are exceeded. The alarm threshold value must always be greater than the warning value. The alarm and warning thresholds must be less than or equal to the full-scale range and must be greater than or equal to the allowed limit.
