CAUSE
Motor temperature above the pre-alarm threshold set
with P09.05.
Motor temperature above the alarm threshold set with
P09.06.
The resistive temperature sensor is an open circuit (dis-
connected).
Motor temperature below the alarm threshold set by
P09.07.
Motor temperature above the pre-alarm threshold set by
P10.05.
Motor temperature above the alarm threshold set by
P10.06.
The resistive temperature sensor is an open circuit (dis-
connected).
Motor temperature below the alarm threshold set by
P10.07.
Motor excess temperature signalled by activation of the
digital input programmed with the appropriate function -
High motor temperature.
Alarm generated by the input programmed with the
function - Motor temperature too low.
Motor oil pressure lower than the pre-alarm threshold set
with P08.06.
Motor oil pressure lower than the alarm threshold set
with P08.07.
The resistive pressure sensor is an open circuit (discon-
nected).
Low oil pressure signalled by activation of the digital in-
put programmed with the appropriate function.
