Monitor
0.0 to 100.0%
The percentage of the electronic ther-
mal calculated value for motor protec-
tion at the current moment is displayed.
If the percentage reaches 100.0%, the
dBH alarm occurs.

Monitor
0.0 to 100.0%
The percentage of the electronic ther-
mal calculated value for motor protec-
tion at the current moment is displayed.
If the percentage reaches 100.0%, the
OL1 (1st motor overload) or OL2 (2nd
motor overload) (depending on whether
the 1st control or 2nd control is select-
ed) occurs.
