Figure 81: Time between starts
15.2 NUMBER OF STARTS LIMITATION
Repeated starting, or intermittent operation of a motor, can generate dangerously high temperatures within the
motor
, unless sufficient time is allowed for cooling between starts.
The P24xM relay incorporates several starts limitation facilities. This limitation is fully programmable.
Restarting the motor from a hot thermal state
For certain applications do not allow the motor time to cool down to a specified thermal state before a re-start is
permitted. The P24xM relay incorporates several features which allow a subsequent start from a hot thermal state.
These are discussed in the section on 'thermal overload protection'.
The motor accumulated run time displayed in the menu cell Motor Run. Time of the MEASUREMENTS 3 menu is
initiated each time the switching device is closed and remains closed.
