Control Inputs Two speed inputs that are jumper configurable for MPU (magnetic pickup units) inputs or proximity probes. Six programmable analog inputs can be used as one of the following options: auxiliary input, remote auxiliary setpoint, cascade input, remote cascade setpoint, kW (load) input, remote speed setpoint, synchronizing, load sharing, both synchronizing and load sharing, and first stage pressure. The sixth analog input has isolation circuitry and should be used for a self-powered signal that is not isolated. 505 Digital Governor Manual 85017V1 6 Woodward Sixteen contact inputs are available. Four are dedicated for shutdown, reset, raise speed setpoint, and lower speed setpoint. Another two contact inputs must be dedicated for generator breaker and utility tie breaker if the control is used in a generator application. Ten additional contact inputs can be configured. If the unit is not used in a generator application, then twelve additional contact inputs can be configured. Four function keys on the front panel of the control. F1 and F2 are dedicated to alarm and overspeed, respectively. F3 and F4 can be used to enable or disable various functions of the control. Control Outputs Two actuator outputs with linearization curves; the second actuator output can be used as an extra readout if not used as an actuator output. Six 4–20 mA outputs, for meters or other readouts. Eight Form-C relay contact outputs, six that are configurable. The two dedicated relay outputs are for shutdown and alarm indication. Control Interfaces Two Modbus ports, to be used as control interfaces. The protocol can be either ASCII or RTU and the communications can be RS-232, RS-422, or RS-485. One computer (PC) port to be used for program configuration storage. An overview of the 505 functions is shown in Figure 1-3. Use this block diagram to match the control features to the site-specific application required. Control Overview The 505 has two independent control channels, the speed/load and auxiliary controllers. The outputs of these two controllers are low-signal-selected (LSS) with another channel, the valve limiter. The output of the LSS directly sets the position of the actuator driver’s output. In addition to these channels, the speed/load controller can be manipulated by another controller, the cascade controller. The cascade controller is ‘cascaded’ into the speed controller, whereby the speed controller setpoint is changed directly by the cascade controller output. The auxiliary controller can act as either a control channel or as a limiting channel. All three of these PID controllers have the option of utilizing an analog input signal to remotely position their setpoints. Additional features of the 505 include frequency control, isochronous loadsharing
