198 9369700990 Rev R
Current Unbalance
Indication that the power system stabilizer is disabled by a current unbalance condition.
Power Below Threshold
Indication that the real power is below the threshold for the power system stabilizer to activate.
Speed Failure
Indication that the power system stabilizer is disabled due to an error in speed measurement.
PSS Volt Limit
Indication of an active power system stabilizer voltage limiter.
Clock Reset
Indication that the clock has been reset.
Manual Mode
Indication that the regulator is in manual mode.
FVR Mode
Status indication of field voltage regulation (0=off, 1=on) (DECS-400 does not need to be in Start).
Inner Loop Enable
Indication that the inner loop field regulator control function is enabled.
Pre-Position Traverse Enable
Indication that the pre-position traverse function is enabled.
PSS ROC Enable
Indication that the PSS rate-of-change function is enabled.
Var Limit
Indication that the reactive power limiter is active.
PSS Block
Indication that power system stabilizer operation is blocked.
Outputs
Start
Starts the DECS-400 (latching).
Stop
Stops the DECS-400 (latching).
Parallel
52L/M contact (forces the regulator into droop whenever it is true) (dependent upon BESTCOMS enable
checkbox and/or Droop Enable logic input).
Pre Position 2
Returns the active setpoint to its programmed pre position 2 level.
AVR
Puts the DECS-400 in auto mode (latching).
Programmable Logic DECS-400
