Woodward 13
Calibration Mode –
This mode is used to calibrate, tune and adjust certain parameters either while the unit is shutdown, or
during turbine run time. A password is required to log into this mode.
Operation Mode -
This mode is the typical state for normal operations of the control and the turbine. The Run Mode is used
to operate the turbine from start-up through shutdown.
505 Inputs and outputs
Control Inputs
Speed Input Signals
Two redundant speed inputs are configurable to accept MPUs (magnetic pickup units), or active proximity
probes.
Analog 4-20mA Input Signals
There are eight configurable analog inputs available on the 505 hardware, each of which can be
configured as one of the following input functions:
Table 1-1. Selectable functions for 4-20mA Analog Inputs
1- Not used
2- Pond / Tail level
3- Generator Power
4- Speed Bias
5- Remote Speed Reference
6- Nozzle Position Limiter
7- Remote Baseload reference 8- Remote level reference
9- Nozzle 1 Position feedback
10- Nozzle 2 Position feedback
11- Nozzle 3 Position feedback
12- Nozzle 4 Position feedback
13- Nozzle 5 Position feedback

Discrete Contact Input Signals
Twenty contact inputs are available. The first five inputs are dedicated for Run/Stop (DI-1), Raise
Speed/load (DI-2), Lower Speed/Load (DI-3), Breaker Closed (DI-4) and Emergency Shutdown (DI-5).
The next 4 channels are configurable as per the list below, but for convenience are defaulted to the
following functions: Deflector closed, Deflector Opened, Baseload Enable and Start Permissive. The rest
of the additional contact inputs are available for configuration to function as various controller discrete
input functions as listed below. On the front panel display there are 4 additional keys that are always
available for operational functions (GREEN keys) – Start/Stop/Reset and Adjust Up/Down for raising or
lowering a highlighted value.
