Note
Deactivation rule
To guarantee motor protection, the trip class cannot be deactivated in the case of a
deactivated temperature sensor (= CLASS OFF).
See also Chapter Data plausibility check (Page 69).
Note
Parameter dependence of thecontrol function soft starter
If the startup mode "direct" is selected for the device parameter "Control function soft
starter", the trip class can only be parameterized to CLASS 5 (10a), CLASS 10 and
deactivated by means of CLASS OFF.
Recovery time
The recovery time is the time defined for cooling after which the system can be reset
following an overload trip.
Trip reset signals present during the recovery time have no effect.
The recovery time after overload tripping is at least 1 minute. The recovery time can be
parameterized and modified between 60 seconds and 1800 seconds. Voltage losses
occurring before this time expires can prolong the recovery time if the basic parameter
"Protection against voltage failure" is active.
Prewarning limit motor heating
The motor starter also assumes a prewarning role, that is, it issues a warning if the motor
temperature limit is exceeded. You use this parameter to preset a percentage motor heating
value as a prewarning limit.
This function is deactivated with a motor heating prewarning limit of 0%.
Prewarning limit - remaining time for tripping
You use this parameter to preset a time as a prewarning limit. The motor starter warns
against imminent overload tripping within the parameterized time if the present operating
conditions are retained. This function is deactivated with a "remaining time for tripping"
prewarning limit of 0%.
