8.3 Repairing
In case it is confirmed that the AVR is defective, we recommend to contact Beltrame CSE to agree about repairing conditions.
We strongly recommend to avoid to return back any devices without previous agreement.
The user is responsible for the correct packaging of the regulator.
Unstable or Low Output Voltage under load operation
• Compared excitation voltage with power supply voltage
• Check programmable digital input setting and connection
• Check parameters of voltage regulator
• Regulator error
• Set point error
• Control element fault
• Check/adjust stability settings r.350 and r.351
• Unstable Increase/Decrease inputs
• Unstable External analog input
• Check wiring for loose contacts
Operating point cannot be adjusted
• Check operating mode
• Check set point
• Check connections
• Set point error
• Limiter active
• Check programmable analog and digitale input
• Bring machine into normal operating range by adjusting the set point
• Check setting of limiters
Irregular instability, i.e. sporadic over - or under excitation which is not caused by grid variation
• Check droop compensation setting
• Check external current transformer circuit
• Gen CB Closed Status not active
• Poor effect of the Droop influence on the
voltage regulator or C.T. defective
measurement
• Some limiters are active: machine within
inadmissible operating range
• Check programmable digital input setting and connection
• Bring machine into normal operating range by adjusting the set point.
• Check setting of limiters
Problems with External (remote) controls
• Measure control voltage
• Check wiring
• No external control voltage
• Configuration of the digital or analog
inputs are not correct
• Check configuration
Unstable parallel operation with grid
Periodic oscillation of reactive and active power (instability)
• Were changes made to the grid configuration?
• Are additional outputs, loads etc. installed?
Yes: re-set regulator
No: check parameters of Auto and PF, Var regulator
• Check/adjust stability settings
• Not correct regulator settings
