Ramp time too short Air Actuator Actuator operates with too short a ramp
time, or with an angular rotation that is too
long for the ramp time
Internal Fault Air Actuator Timeout during A/D conversion

Meaning for the LMV5x system Troubleshooting
Recommendation:
1. Match ramp time to the slowest actuator in the system
(SQM48.4/6), OR
2. Reduce the actuator's angular rotation between special
positions (load stages with multistage operation) based on
angular rotation
= 90° * ramp time / (90°running time of SA)
Check to see if actuator is within the valid positioning range
(0-90°)

Reset the unit.
! Caution ! If fault occurred during parameterization: Check
the parameters changed last.
If fault cannot be rectified by the reset: Restore AZL...
