Figure 4.4: Relation Start Period/Start Blocking Time with firm Start Blocking Time
Thermal Image
A start is always possible as long as there is enough thermal reserve for a start. This start limitation
is a dynamic one and is orientated on the data the thermal image is parameterized with. For this
the MRM3-2 detects the average thermal load of the latest starts. With the motor shut down, the
start blocking relay is activated for the time when there is not enough thermal re-serve in the sto-
rage through cooling down to enable a new start.
