The "505" is a microprocessor-based digital regulator for turbine control systems for generators, compressors and pumps.
The 505 regulator is used to control the turbine speed, power, pump or compressor feed pressure and other turbine-related process parameters.
Examples of 505 regulators and their applications are given in the Appendix.
0-0641-T. Nr-00.
The 505 regulator can be used stand-alone or can be connected to the plant distribution control system (DCS) and PC via three serial interfaces.
The communication interfaces are configured for RS-232, RS-422 or RS-485 communication according to ASCI or RTU as required.
The 505 regulator is available in both tray-mounted and rack-mounted versions to suit the different requirements of the user.
The 505 regulator can be installed in the control room or next to the machine, their shape and mounting dimensions are shown in Appendix 2.
The 505 regulator can be installed in the control room or next to the machine.
All inputs and outputs of the 505 regulator are connected via a cage clamp terminal block on the back of the enclosure.
The terminal block of the 505 regulator is shown in appendix 3.
For the selection of the jumper, please refer to the woodward 505 manual.
Operation
The operating panel of the 505 regulator consists of a display and a keypad. The display has two lines of 24 characters each. The keypad has 30
touch keys. During operation each program step is shown in turn in the display and the actual values of the set parameters and the given values can be seen simultaneously on the display screen when the unit is in operation.
The actual and given values of the set parameters are visible on the monitor screen when the unit is running.
