Woodward
The unit “RPM” represents revolutions per minute. The unit “RPM/MIN”
represents change in rpm per minute. The unit “ENGR” represents engineering
units which are user set (psi, kPa, etc). The unit “Hz” represents frequency in
Hertz. The unit “SEC” represents seconds. The unit “%FD” represents a
percentage of the Fuel Demand as described in the Description of Operation in
Chapter 6. Use the Appendix to enter the specific values for your application.
CFIG OPTIONS
The items under this menu configure general dynamics and fuel limit options.
Set
the item value to TRUE to enable the option.
USE REV ACTUATOR
Set to FALSE when the actuator current increases to
increase fuel flow, and set to TRUE when the actuator current decreases to
increase fuel flow. The TRUE setting is used with actuators that increase the fuel
flow to the engine if the electrical signal to the actuator fails. Changing this
setting to TRUE affects the operation of the Start Fuel Limit Function (see
Description of Operation in Chapter 6 for details).
USE 2nd DYNAMICS
Allows the 2nd Dynamics discrete input to be active. This
input is not active when set to FALSE.
DYNAMICS 1 CONSTANT
Determines whether the speed control GAIN and
RESET values are constant or vary as a function of engine speed. GAIN and
RESET vary with engine speed when set to FALSE.
USE TORSIONAL FILTER
Allows the ENABLE TORS FILTER to be active.
The Torsional Filter is not active when set to FALSE even if ENABLE TORS
FILTER is set TRUE.
USE NOTCH FILTER
—Enables/disables a Notch Filter on the speed input(s).
Set TRUE to enable the notch filter and disable the torsional filter. Set to FALSE
to disable the notch filter and permit the torsional filter to be enabled.
USE AIR MAN LIMIT
Allows the ENABLE AMP FUEL LMT to be active. The
Air Manifold Pressure Fuel Limit is not active when set to FALSE even if
ENABLE AMP FUEL LMT is set TRUE.
USE TORQ LIMIT
Allows the ENABLE TORQ FUEL LMT to be active. The
Torque Fuel Limit is not active when set to FALSE even if ENABLE TORQ FUEL
LMT is set TRUE.
RESET ALM ON CLEAR
Enables automatic ALARM RESET on every start.
The automatic ALARM RESET is not active when set to FALSE. Manual alarm
reset through the discrete input or Hand Held programmer is not affected and
always enabled.
NON-LATCH ALM DOUT3
—Set FALSE to make Relay 3 output a latching
output. A configured Engine Trouble condition must be
cleared and reset
to
unlatch Relay 3 output. Set TRUE to make the Relay 3 output non-latching. A
configured Engine Trouble condition must be
cleared only
to unlatch Relay 3
output.
CFIG SPEED CONTROL
The items under this menu configure the speed inputs. It is critical to control
operation that these items be set correctly.
RATED SPEED (RPM)
—Enter the rated speed in rpm. This is the speed that the
speed reference automatically ramps to when the Rated Speed discrete input is
“TRUE”.
ASPD #1 TEETH
—This is the number of pulses per revolution seen by Speed
Sensor #1. It is generally the number of teeth on the gear used by an MPU.
ASPD 1 MAX FREQ (Hz)
—This is the absolute maximum frequency that is input
to Speed Sensor #1. It is generally set greater than the frequency representing
an overspeed condition.
