Monitoring, pump/fan
The monitoring functions for pumps and fans are similar. The blocking protection applies
equally to both applications.
For pumps, there is also a leakage monitoring function.
Principle of operation
Within speed thresholds 1 and 3, the inverter monitors the torque and the speed for pumps
and fans.
If the torque or the speed moves, for longer than the time set in p2192, in the ranges of
blockage, leakage or dry running protection/belt breakage, then the response defined in
p2181 is realized.
