Description
3.10 EFB reference 2 (page
Parameter 9.13 Motor current estimated (page
Estimated motor current in % of nominal motor current.
See Terms and abbreviations (page
Defines low limit value for the Supervision low function.
See parameter 81.41 Supervision low signal
Supervision low limit.
Defines delay time for the Supervision low function.
See parameter 81.41 Supervision low signal
Supervision low delay.
Defines the source for the supervision high signal.
The value of this parameter is then compared with the
limit set in parameter
If the observed signal is greater than the limit for the
time period set in parameter
delay, then the current cleaning step is interrupted.
Cleaning sequence will proceed for the off-time and
then switch to the next cleaning step. The supervision
high is not active during the off-time period.
Note: For the Supervision High function to work,
parameter 81.02 Pump cleaning option
be set to 1.
