indication
Description
4-1 30) Overvoltage Voltage has exceeded
level set for a predefined
time
4-2 31) Max. sense
voltage drop
reached
4-3 32) TCLIN Overvoltage
Possible reason
Measure to rectify
10
Load shedding with high voltage already
Activate load shedding detection
Increase control parameters
Use adaptive control parameters
Connect an additional capacitor
After consultation with the manufacturer,
it may be possible to increase the error delay
Controller oscillation
Reduce control parameters.
Possibly increase P term
Overshooting on set value step
Reduce gradient on the set value ramp
Reduce control parameters
Overshooting with no load: use adaptive
voltage control parameters
Difference between module voltage and sense voltage has exceeded the limit
set for a specific time (delay)
Adjust monitoring level and delay to actual situation.
Possibly deactivate monitoring, if not required
Use lower resistance load feed cable
Do not disconnect load feed cable
Voltage exceeds limit Controller is unstable
Reduce gain
Reduce drop voltage
Reduce input voltage
