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 Load Setpoint can be changed when the unit is On-Line from screens 1, 2, or 3 by selecting the ADJUST UP or DOWN. In addition, the Load Setpt can be adjusted by closing a Speed Setpoint Raise/Lower contact inputs or selecting Speed Setpoint Raise or Lower commands from either Modbus communications link. In addition, the Load setpoint can be directly set to a value by pressing the ENTER key from the SPEED screen and entering a speed setpoint value, or Entering a new Speed/Load Setpoint through either Modbus communications link.

Cascade (CAS) Key Screens For this key to be active, the Cascade function must be programmed. Figure 5- 15 shows the possible screens that may appear if the CAS key is pressed. Only the screens related to the Cascade functionality programmed will be displayed. Only when the Remote Cascade Setpoint is programmed, will screen 3 appear. The Cascade PID dynamic and droop values can be adjusted from these screens. Cascade control can be enabled by pressing the front panel YES key from the Status screen (screen 2), closing the Cascade Control Enable/Disable contact (if programmed), or selecting Cascade Enable from either Modbus communications link.

Cascade control is disabled by pressing the front panel NO key from the Cascade Status screen (screen 2), opening the Cascade Control Enable/Disable contact (if programmed), or selecting Cascade Disable from either Modbus communications link. Cascade control is also disabled if Auxiliary control is enabled or Remote Speed Setpoint input is enabled. Cascade control is disabled and ‘inhibited’ if a controlled shutdown is selected, the cascade input fails, or the unit shuts down. Cascade control can be ‘enabled but not active’ if the generator and/or utility tie breaker are open. Since the Cascade PID controls through the Speed setpoint and Speed PID, Cascade will only be “In Control” when the Speed PID is “In Control” of the actuator output. 

See Table 5-11 for all possible cascade control messages. Figure 5-15. CAS Key Screens The Cascade setpoint can be configured to either track the input for bumpless transfer into control or remain at the last setting. When using the tracking option, the cascade setpoint cannot be changed until Cascade control is enabled. The Cascade setpoint can be changed by pressing the ADJUST UP or DOWN keys from the Cascade setpoint screen (screen 1), closing a cascade Setpt Raise/Lower contact input, or selecting Cascade Setpoint Raise or Lower commands from either Modbus communications link. In addition, the Cascade setpoint can be directly set to a value by pressing the front panel ENTER key from the Cascade Setpt screen or by Entering a new Cascade Setpt through either Modbus communications link.
