Various actions:
When the user activates the cold treatment, a trips start mark and event is automatically made.
Multiple Temperature Setpoint (MTS)
To be able of transporting a commodity under the best possible temperature scheme, the MP4000 is
capable of controlling the temperature through a set of temperatures.
The scheme is defined by user pre programmed temperature setpoints and time periods.
The fix point list for the temperature scheme programming allows for up to 9 different sets of
temperatures and periods.
• 9 sets of temperature setpoints
• 8 sets of timing in between the 9 setpoints.
Figure 115: Example of MTS Log
Trip Actions and States:
• The container is prepared, initiated with setpoints and parameters for the journey and transported
to the loading location. The refrigeration unit will, if powered, start approaching the first setpoint.
• The next setpoint will be approached within the maximum capabilities of the unit, as if a user
manually has changed the setpoint.
• The timing for any period will start when the supply air approach for the setpoint is within the IN
RANGE setting. The timing will not stop or restart even though the supply air gets out range.
• The temperature setting will be kept through the specified period and when the period ends the
next set of parameters will be activated.
During the treatment a set of events is made together with the temperature logging to document the
journey.
