Description of alarms
CODE
DESCRIPTION
CAUSE
A01
Motor temperature pre-alarm 1 (analogue sensor)
Motor temperature above the pre-alarm threshold set
with P09.05.
A02
High temperature motor 1 (analogue sensor)
Motor temperature above the alarm threshold set with
P09.06.
A03
Temperature sensor fault 1 (analogue sensor)
The resistive temperature sensor is an open circuit (dis-
connected).
A04
Low motor temperature 1 (analogue sensor)
Motor temperature below the alarm threshold set by
P09.07.
A05
Pre-alarm motor temperature 2 (analogue sensor)
Motor temperature above the pre-alarm threshold set by
P10.05.
A06
High temperature motor 2 (analogue sensor)
Motor temperature above the alarm threshold set by
P10.06.
A07
Analogue temperature sensor fault 2
The resistive temperature sensor is an open circuit (dis-
connected).
A08
Low temperature motor 2 (analogue sensor)
Motor temperature below the alarm threshold set by
P10.07.
A09
High motor temperature (digital sensor)
Motor excess temperature signalled by activation of the
digital input programmed with the appropriate function -
High motor temperature.
A10
Motor temperature too low (digital). Heater failure. (Motor tem-
perature too low (digital), heater failure.)
Alarm generated by the input programmed with the
function - Motor temperature too low.
A11
Oil pressure pre-alarm (analogue sensor)
Motor oil pressure lower than the pre-alarm threshold set
with P08.06.
A12
Low oil pressure (analogue sensor)
Motor oil pressure lower than the alarm threshold set
with P08.07.
A13
Analogue pressure sensor failure
The resistive pressure sensor is an open circuit (discon-
nected).
A14
Low oil pressure (digital sensor)
Low oil pressure signalled by activation of the digital in-
put programmed with the appropriate function.
