Module of PLC, DCS, ESD system card, the card is a vibration monitoring system, steam turbine control system module, the advantages of the gas generator spare parts brand: Allen Bradley, BentlyNevada, ABB, Emerson Ovation, Honeywell DCS, Rockwell ICS Triplex, FOXBORO, Schneider PLC, GE Fanuc, Motorola, HIMA, TRICONEX, Prosoft etc. Various kinds of imported industrial parts of our products are widely used in metallurgy, petroleum, glass, aluminum manufacturing, petrochemical industry, coal mine, papermaking, printing, textile printing and dyeing, mechanical, electronic manufacturing, automobile manufacturing, plastic machinery, electric power, water conservancy, water treatment/environmental protection, boiler heating, energy, power transmission and distribution and so on.

The following valve limiter indications are available through the Modbus links: HP Valve Limiter at Min, HP Valve Limiter at Max, and HP Valve Limiter In Control of actuator output, LP Valve Limiter at Min, LP Valve Limiter at Max, and LP Valve Limiter In Control of actuator output. In addition to these indications the HP Valve Limiter Setpoint, HP Valve Demand, HP Valve Output, LP Valve Limiter Setpoint, LP Valve Demand, and LP Valve Output analog values are also available.

Figure 5-8 shows the possible screens that may appear if the ACTR key is pressed. The only parameter that can be adjusted from these screens is the dither setting. To adjust the dither setting (if required), the @ symbol must be on the display line containing the asterisk/dither value to tune. The @ symbol is moved using the SELECT key. The communications links will display the HP Valve Demand, LP Valve Demand, HP Valve Position in milliamps, LP Valve Position in milliamps, values as well as the actual Actuator Output Current for both actuators in milliamps.

Figure 5-9 shows the screens that appear when the CONT key is pressed. The CONT key allows operators to monitor what 505E parameters are controlling governor valve positions (screen 1). From screen 2 the steam map limiter priority can be seen and changed (if programmed). From screen 3 the cause of the last turbine shutdown can be viewed and from screen 4 the highest turbine speed reached can be viewed and cleared, if desired. Screen 5 can be used to change and display the Local/Remote status, if used.

For a complete listing of Shutdown/Trip causes, refer to the Trips section later in this chapter. Table 5-5 lists the Priority status messages that may appear on the front panel display and the meanings of each. MESSAGE 9 MEANING Speed Priority Active Speed Priority is Active for steam map limit(s) Extr Priority Active Extraction Priority is Active for steam map limit(s) E/A Priority Active Extr/Adm Priority is Active for steam map limit(s) Adm Priority Active Admission Priority is Active for steam map limit(s) Ext Active/Spd Selected Speed Priority is selected but Extraction Priority is in control Prs Active/Spd Selected Speed Priority is selected but Extr/Adm Priority is in control Adm Active/Spd Selected Speed Priority is selected but Admission Priority is in control Spd Active/ Ext Selected Extraction Priority is selected but Speed Priority is in control Spd Active/ Prs Selected Extr/Adm Priority is selected but Speed Priority is in control Spd Active/ Adm Selected Admission Priority is selected but Speed Priority is in control Priority Xfer Inhibited Priority transfer selected but allowed-permissives are not met; on a limit, generator or tie breaker open Auto Switching Config’d Priority transfer selected but not used; auto transfer is configured Priority Swtch Not Used Priority transfer selected but not used (speed priority is programmed and switching to Ext/Adm is not permitted) Table 5-5. Priority Messages The Controlling Parameter, Priority Status, and Highest Speed Reached values are available through the Modbus links.
