    REFRIGERATION CIRCUIT Starting at the compressor (see Figure 2.16), the suction gas is compressed to a higher pressure and temperature. The gas flows through the discharge service valve into the pressure regulating valve. During periods of low ambi- ent operation, the discharge pressure regulating valve maintains the flow of refrigerant to a preset minimum dis- charge pressure.

  • Page 40: Unit Pre-Trip Diagnostics

    Some alarms requiring compressor shutdown have time delays before and after to try to keep the compressor on line. An example is alarm code “LO”, (low main voltage). When a voltage drop of over 25% occurs, an indication is given on the display, but the unit will continue to run. An alarm is indicated by flashing an alarm code on the display panel, and for some alarms, by the alarm light illumi- nating.
