WARNING Explosion Hazard–Do not connect or disconnect while circuit is live unless area is known to be non-hazardous. Explosion Hazard–Substitution of components may impair suitability for Class I, Division 2 or Zone 2 applications. AVERTISSEMENT Risque d’explosion–Ne pas raccorder ni débrancher tant que l’installation est sous tension, sauf en cas l’ambiance est décidément non dangereuse. Risque d’explosion–La substitution de composants peut rendre ce matériel inacceptable pour les emplacements de Classe I, applications Division 2 ou Zone 2. 505E Software Changes Covered in this Manual Revision 1. PROGRAM MODE: Made all start modes default to false to ensure a customer programmed the unit. Also added an error check to ensure Rated Speed (when programmed as a gen set) was less than max gov. 2. SERVICE MODE: Changed the hold changes for Min Load to come from the Breaker Logic header's Hold Changes input. Previously the hold changes command was selected under the Speed Control Settings header. 3. SPEED SETPOINT RATES: Changed the minimum adjustment range for all speed setpoint rates to 0.01 (was 0.1). 4. AUX LIMITER or CONTROLLER: Added logic to ensure 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 open 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. 7. AUX, CASC, and EXTR DROOP: Changed 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 breaker 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 listing. *—Modbus is a trademark of Modicon, Inc. 10. CONTROLLED STOP: Made 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.
