Motor Protection
7.1 Overload Protection
SIMOCODE PRO V PN FDI
26 Programming and Operating Manual, 05/2020, A5E44499659002A/RS-AA/001
Response in case of overload
The response of SIMOCODE pro can be additionally adjusted in case of overload.
Note
With motors for EEx e applications the response must remain set to "tripping"!
Cooling down period (CiR)
The cooling down period is the specified time after which an overload tripping can be reset. It
is usually five minutes. The thermal memory is deleted after the cooling down period expires.
Supply voltage failures of SIMOCODE pro during this time correspondingly extend the
specified time.
Pause time (CiR)
The pause time is the specified time for the cooling response of the motor when switching off
under normal operating conditions (not in the case of overload tripping!). After this interval,
the thermal memory in SIMOCODE pro is deleted and a new cold start is possible. Due to
this, frequent start-ups within a short period of time are possible.
Note
The motor and the switchgear must be dimensioned specifically for this load!
Type of load
The phase failure monitoring is deactivated automatically.
You can choose whether SIMOCODE pro is to protect a 1-phase or a 3-phase load.
With a 1-phase load, the following measures should be carried out:
● The internal earth-fault monitoring and the unbalance protection must be deactivated.
● Only one of the two cables should be feed through a push-through system opening in the
current measuring module.
