MP4000 Controller Specification
| Temperature Controller: | |
| Type | MP-4000 is a controller module for the Thermo King Reefer Units. 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. |
| Setpoint Range |
-40.0 to +30.0 C (-40.0 to +86.0 F) — Magnum+ -30.0 to +30.0 C (-22.0 to +86.0 F) — CFF |
| Temperature Display Range | -70.0 to +80.0 C (-94.0 to +176.0 F) |
| Controller Software | |
| Version | See controller display |
| 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). | |
| Demand Defrost | Demand defrost function initiates defrost when: Temperature difference between the return air sensor and defrost (evaporator coil) sensor is too large for 90 minutes Temperature difference between the supply air sensors and return air sensor is too large |
| Defrost Timer: | |
| Chilled mode | Evaporator Coil Temperature must be below 5C (41 F) to activate the defrost compressor hour timer. |
| Chilled Mode (continued) | There is an interval set for defrosting, however, the defrost timer is built intelligent - it detects whether or not there is ice building up on the coil. If there is no ice building up on the coil, it extends the defrost interval, and if there is Ice building up earlier on the coil it reduces the defrost interval. The maximum interval is 48 hours. |
| Frozen mode | Every 8 hours of compressor operation. Defrost interval increases 2 hours each timed defrost interval. Maximum time interval in Frozen mode is 24 hours. |
| Reset to Base Time | Defrost timer resets if the unit is off more than 12 hours, setpoint is changed more than 5 C (9 F) or PTI pretrip test occurs. |
| Defrost Termination: | |
| Defrost (Coil) Sensor | Chilled mode: Terminates defrost when coil sensor temperature rises to 18 C (65 F). Frozen mode: Terminates defrost when coil sensor temperature rises to 18 C (65 F). |
| Termination Timer | Terminates defrost after 90 minutes at 60 HZ operation if coil sensor has not terminated defrost (120 minutes at 50 Hz operation) |
| Power Off | Turning Unit On/Off switch Off terminates defrost |
| Compressor Shutdown Protection (Auto Reset): | |
| Stops Compressor | 148 C (298 F) |
| Allows Compressor Start | 90 C (194 F) |
| Bulb Mode: | |
| Evaporator Fan Speed Settings | Flow High: High speed only |
| Flow Low: Low speed only | |
| Flow Cycle: Fans will cycle between low and high speed every 60 minutes | |
| Defrost Termination Temperature Setting | 4 to 30 C (40 to 86 F) |
