What is the function of the PTC probes ?
PTC probes integrated in the motor to measure its temperature can be connected to the control card terminals.
This analog value is managed by the starter.
The "PTC probe thermal overshoot" value can be processed and used in two ways:
- stop in the event of a fault if the signal is active
- activate an alarm if the signal is active. This alarm can be displayed in a starter status word (serial link)
or on a configurable logic output.
Note:
PTC probe protection does not deactivate the motor thermal protection provided by the calculation. Both types
of protection can operate in parallel.
