Input name
Description
Incoming trip
signal
This input is used for tripping the field breaker after the time set in the "Inverter mode time on stopping"
parameter (found under the "Voltage supervision" tab) has passed. This allows the control signal to be set
down ("Phase retard") before opening the field breaker.
Field overcurrent
This input is used to open the field breaker with the set "Open field breaker trip time" parameter (found
under the "Voltage supervision" tab).
This input is read only when the "Control mode" parameter under the "Local control" tab is set to "DI
control".
Speed > 90 %
input
This input is used to indicate that the generator's rotation speed is at least 90 % of the nominal speed.
Generator
breaker status
'Closed in'
This input is used to indicate to the excitation that the generator breaker is closed.
Line breaker
status 'Closed in'
This input is used to indicate to the excitation that the line breaker to the network is closed.
VT Supervision
fail status
This input is used to indicate that there is a fault in the voltage measurement circuits. If an error input is
received, the control mode is switched to FCR.
Activate electrical
braking
This input is used to activate electrical braking.
See also the parameter "FCR reference on electrical braking" under the "FCR" tab.
External islanding
detection
This input is used to bring in external on-island detection information to the excitation. If either the MVAr
or the PF control mode is active, this signal controls the AVR mode ON.
Common trip
This input is used to bring in external tripping information. If the "Internal tripping of field breaker"
parameter (under the "Voltage supervision" tab) has been enabled, the field breaker is controlled open.
Voltage matching
input
This input is used to bring in external voltage matching information.
See also the parameter "Enable voltage matching" under the "AVR" tab.
Backup supply
ON
This input is used to switch over to use the backup supply, for example during a fault in the main supply.
Block
underexcitation
limiter
This input is used to block the underexcitation limiter (UEL), for example during the motor start sequence.
Block field current
limiter (time-
delayed)
This input is used to block the time delayed field current limiter (DFCL).
Block field current
limiter (instant)
This input is used to block the instant field current limiter (IFCL).
Block stator
current limiter
This input is used to block the stator current limiter (SCL).
Motor mode
starting (bypass
FCR starting
ramp)
This input is used to quickly increase the FCR reference value during the motor start sequence.
Block process
panel and remote
control
This input is used to block the process panel and remote control, for example during a motor start.
