4. AUX LIMITER or CONTROLLER: Added logic to ensureYOKOGAWA NFAI841-S00 the inhibited status of Aux control when the input is failed. In addition, changed Aux re-enable logic such that when a failed aux input is restored there is no glitch to the speed LSS. Also changed breaker YOKOGAWA NFAI841-S00open logic to correct a Gen Opening Aux actuator output glitch. 5. AUX CONTROLLER: Changed the speed setpoint aux biasing logic to only allow the speed control limiting action (while in aux control) to be active when the speed setpoint reaches max gov. Prior to this fix the speed limiter could come into control during an extreme transient. 6. AUX DIRECT ENTERED SETPT: Changed Aux Entered setpoint to be reset/ stopped on a shutdown pulse rather than held disabled on a shutdown condition. This change allows the Aux Limiter function direct setpoint entry even when the unit is tripped.YOKOGAWA NFAI841-S00
