11 USE INPUT #2 FAIL TRIP
dflt = FALSE (FALSE, TRUE)
When set TRUE a failure of the input signal gives a major alarm, which
shutdowns the engine. When set FALSE only an alarm is given, and the engine
is not stopped.
F**ACTUATOR OUT OPTIONS**
01 ACTUATOR OUT TYPE (1-4)
dflt = 1 (1
–4)
Selects the current range of the actuator used:
1 = 0-200 mA
2 = 4
–20 mA
3 = 0-20 mA
4 = PWM on DO#1 (When #4 is selected, the actuator output is switched to
Discrete Output #1 to drive a Pulse Width Modulated signal into an actuator that
will accept this type of signal. This is a low-current type of driver. The Frequency,
Duty Cycle, Min and Max Limits are set up below).
02 DISPLAY ACTUATOR TYPE
(monitor)
Displays what current range is set for the actuator.
03 REVERSE ACTING ACTUATOR
dflt = FALSE (FALSE, TRUE)
Set to TRUE for reverse-acting actuators and FALSE for forward-acting
actuators. Forward-acting actuators require current increase to increase fuel.
Reverse-acting actuators require current decrease to increase fuel (reverse-
acting actuators should always incorporate a mechanical ballhead backup
governor, such as the Woodward EGB).
04 SD ACT ON INTERNAL SD
dflt = TRUE (FALSE, TRUE)
Set to TRUE will cause the fuel demand to go to 0% on any internal shutdown
(Forward acting or reverse acting). Set to FALSE will cause the fuel demand to
go to 100% on any internal shutdown. Menu item 03 REVERSE ACTING
ACTUATOR must be set to TRUE and a mechanical ballhead backup governor
must be present before this function will work.
05 PWM FREQUENCY
dflt = 500.00 (300.0
–2000.0)
Sets the Duty Cycle Pulse Width Modulated output frequency of Discrete Output
#1, when 01 ACTUATOR OUT TYPE (1-4) is selected to #4, PWM Output.
06 DUTY CYCLE AT 0%
dflt = 10.00 (-10.00
–110.00)
Sets the minimum Duty Cycle output of Discrete Output #1, when 01
ACTUATOR OUT TYPE (1-4) is selected to #4.
07 DUTY CYCLE AT 100%
dflt = 90.00 (-10.00
–110.00)
Sets the maximum Duty Cycle output of Discrete Output #1, when 01
ACTUATOR OUT TYPE (1-4) is selected to #4.
08 DUTY CYCLE MIN LIMIT
dflt = 10.00 (0.00
–100.00)
Sets the minimum Duty Cycle output limit of Discrete Output #1, when 01
ACTUATOR OUT TYPE (1-4) is selected to #4, PWM Output.
09 DUTY CYCLE MAX LIMIT
dflt = 90.00 (0.0
–100.00)
Sets the maximum Duty Cycle output limit of Discrete Output #1, when 01
ACTUATOR OUT TYPE (1-4) is selected to #4.
