•
Or with the HMI:
•
On the "Master" AVR: the "AVR active" and "AVR online" outputs are active, as well as the output
controlling the contactor (DO10).
•
On the “Online" AVR: the “AVR online" output is active as well as the output controlling the contactor
(DO10).
Step 4
: Check that the measurement and power data is actually reaching the AVRs:
•
The plate disconnect terminals are closed properly.
•
The generator and power voltage sensing circuit-breakers are closed properly in the generator.
•
Check that the status of both AVRs is "OFF".
3.4. Aligning measurements
Once these checks have been done, make sure that the measurements on both AVRs give similar results. This
is done by using two load points on the machine and checking the measurements on the monitor page:
Step 1
: Start the generator
•
Build up to rated speed.
•
Energise the machine by starting field excitation. The voltage should build up to the voltage setpoint without
racing.
•
Check that both AVRs are running, either using EasyReg Advanced, or from the HMI by going to the
Regulation status page:
•
On the "Master" AVR,
the regulation mode is displayed:
•
On the "Online" AVR,
the regulation mode is "Redundancy":
