Recovery time (can only be parameterized with high feature motor starters)
The ’recovery time’ is the time defined for cooling after which a reset is possible
following an overload trip.
Trip reset signals received during the recovery time (DO 0.3) have no effect.
The motor starters are set to the following times:
• with DSe ST, RSe ST:
Setting fixed to 90 s.
• with DSe HF, RSe HF, sDSSte / sDSte and sRSSte / sRSte:
The recovery time after overload tripping is at least 1 minute. The recovery
time can be parameterized and can be changed between 60 seconds and
1800 seconds.
Factory setting: 90 seconds
Power failures during this time extend the time specifications accordingly
when the basic ’Non-resetting on voltage failure’ parameter is active.
Prewarning limit value for motor heating
This parameter can be used to specify a percentage motor heating process
as a prewarning limit. The motor starter issues a warning if the parameterized
motor heating limit is exceeded. A shutdown is implemented at 100 %.
Range: 0 % to 95 %.
Prewarning limit value time-based trigger reserve
This parameter can be used to specify a time as a prewarning limit. The motor
starter warns against an impending overload shutdown within the parameter-
ized time if the current operating conditions are observed.
Range: 0 seconds to 500 seconds.
