The type of compressor will determine how the compressor is controlled and its particular Relay Output sequence.
7.6. Compressor Setup and Options
All setup information and option selection is completed in MCS-Config.
General Information
7.6.1.
A maximum of four steps per compressor is supported (compressor plus three additional steps of either
compressors, unloaders, or hot gas bypass points). Note: Compressor safeties relate to a circuit. If
multiple compressors are on a single circuit and a safety trips, all compressors on that circuit will be turned
off (If hot gas bypass, refer to Hot Gas Bypass section 7.15).
If the compressor has an across-the-line start, only one RO point will be allocated for the compressor. If
the compressor has a part winding start, two RO points will be used. The first RO will be turned on and
the second RO will turn on after Setpoint #73 has been fulfilled.
Pump down will take place when the compressor is started and when turning off. Note: When the
compressor is started the liquid line solenoid is not opened until the suction pressure drops below Setpoint
#61 “PMP DWN OFF” or Setpoint #62 “PMP DWN DELY” is exceeded. A liquid line solenoid is required
for the pump down to function correctly.
Up to 3 liquid line solenoids and up to 2 EXV valves are supported for each circuit.
Compressor Information setup
7.6.2.
In this screen under the MAG V8 screen, compressor type is selected from a drop down list. Additional information
about the compressor and how it will be controlled is also provided in this section. Review all cells and input the proper
information.
