STS PTM.MTNEx 131299 cable
AUX, CASC, and EXTR DROOP: STS PTM.MTNEx 131299Changed the droop feedback lag-tau tunable range from a max of 10 to a max of 1000. 8. DECOUPLED CASCADE CONTROL: Added a lag to the speed the speed setpoint is using during a utility tie STS PTM.MTNEx 131299breaker open setback. Also updated the logic used to reset the speed setpoint to minimize to bump experienced when Decoupled Casc is disabled. Changed logic to fix a problem where breaker opening while in the Cascade decoupled mode would cause the HP valve to close then open unexpectedly. 9. MODBUS: Changed the Gen and Tie Open alarms for Aux, Casc, and Remote to match the Modbus listing - the software eventlatch inputs were reversed/backwards with the Modbus listingSTS PTM.MTNEx 131299
CONTROLLED STOP: STS PTM.MTNEx 131299Made the Controlled Stop abort if speed raise/lower is selected or another control mode is selected. This can be tuned-out by setting CNTRL_STOP.RL_STOP.IN_2=*false in the debug mode. 11. ANALOG INPUTS: Changed max setting STS PTM.MTNEx 131299on the delay time’s tunable range from 3 msec to 3000 msec. The analog input failure delay setting is defaulted to zero but can be adjusted up to 3000msec using the debug mode MAIN.AIx.LATCH_DLY where x is the analog input number. Added a tunable single pole filter (LAG) to each analog input. Output/input = 1/(1+st) where t = 1/(2(pi)f) = LAG_TAU. The Lag-tau is defaulted to zero but can be adjusted in the debug mode using MAIN.AIx_LAG.LAG_TAU where x is the analog input number (ie 1-6).STS PTM.MTNEx 131299
