2.2.7 Alarm on Local Display: Position Sensor
(Hardware 11 or Hardware 12)
POSITION SENSOR
The value of the actuator position is not valid in terms of bit, i.e. is not within the set range of bits.
Recongure the stroke limits.
The fault reason may be reconducted to
an external unconventional operation to
the actuator.
Check in sequence:
1. Verify the cabling between the
position sensor and the logic card
(CN14).
2. Replace the position sensor.
3. Replace the logic card.
4. Verify the mechanical integrity of
the shaft of the position sensor.
If the alarm disappears, recalibrate both
stroke limits.
