OL
OL will alternately blink with the normal display on the LED display when
motor thermal overload content has reached 90% to 99% of its capacity.
OLL
The motor thermal overload content has reached 100%, and the motor has
stopped. The motor cannot be restarted until the overloaded motor has
cooled and OLt is displayed.
OLt
The motor thermal overload content has been reduced to 60% or less, and
the motor can be restarted.
ena

dis
Passcode is disabled.
oxx
xx = overload thermal content in percentage. Press the Down button to
toggle to this display.
