Suction and discharge pressures vary too greatly during Modulation Cool to use for evaluating or diagnosing refrigeration
system performance. During the Modulation Cool mode, the suction pressure will vary between 100 and 450 kPa, 1.0 and 4.5
bar, 15 and 65 psig depending upon the percent (percent) cooling capacity.
**Discharge pressure is determined by condenser fan cycling.
MP-4000 Controller Specifications
Temperature Controller:
Type
MP-4000 is a controller module for the Thermo King
Unit. Additional requirements can be met by means of expansion
modules. The MP4000 is solely responsible for temperature
regulation of the reefer container, but other monitoring equipment
can be used in conjunction with the MP 4000 - such as a chart
recorder.
Setpoint Range -40.0 to +30.0 C (-31.0 to +86.0 F)
Digital Temperature Display -60.0 to +80.0 C (-76.0 to +176.0 F)
Controller Software (Original Equipment):
Version See controller identification decal
Defrost Initiation:
Evaporator Coil Sensor
• Manual Switch or Demand Defrost Initiation: Coil must be
below 18 C (65 F). Defrost cycle starts when technician or
controller requests defrost initiation.
• Timed Defrost Initiation: Coil must be below 4 C (41 F). Defrost
cycle starts 1 minute after the hour immediately following a
defrost timer request for defrost initiation. For example, if the
defrost timer requests a defrost cycle at 7:35, the defrost cycle
will start at 8:01. Datalogger will record a Defrost event for each
interval in which a Defrost cycle is pending or active (i.e. both the
8:00 and 9:00 data logs).
