Meaning for the LMV5x System
Fault with Connected Actuators
Page too long open
Page disrupted
Invalid parameter access
Fault during copying of parameter page
External plausibility fault. This type of fault covers possible
faults occurring due to invalid presettings in the drive
commands. In response, the presettings will be ignored
Internal plausibility fault. This type of fault covers possible
faults that can occur due to strong electrical noise
Fault with Base Unit (LMV5) Internal Load Controller
Internal load controller has detected a fault. Type of fault: See
diagnostic code
-
Invalid XP identified
Invalid TN identified
TU longer than identification time
Invalid TV identified
Timeout during observation time
A warning indicating that the Cold Start Thermal Shock
Protection (CSTP) is activated
Timeout during delivery of adaption rate and while process is
being watched
The current setpoint (W1, W2, W3) is above the value of the
internal temperature limiter.
1) Reset the LMV5
2) If fault occurred after changing a parameter, check
the parameters that were last changed.
3) If fault cannot be rectified by the reset: Restore
parameters form the AZL to the LMV5
4) If fault occurs continuously, replace LMV5.
1) Check the paramters related to special positions.
The special positions of each activated actuator should
be programmed between 0 and 90 degrees.
1) If fault occurs sporadically: Reduce electrical noise.
If fault occurs sporadically, reduce electrical noise.
If fault occurs continuously, replace LMV5.
PV (Process Varible) is not changing in response to
firing rate during the adaption time. Adaption times out
due to lack of change in the measured PV. Check
sensor and thermal system.
This can be deactivated, if desired. See parameters
concerning the load controller in the settings section.

Raise the value of the internal temperaure limiter or
decrease the current setpoint.
