Woodward 85
09 ACTUATOR CURRENT (mA) (monitor)
The calculated actuator output current in milliamps. This calculation is based on
the percent fuel demand and the actuator type/range selected. External wiring
may affect the accuracy of the actual current.
10 ANALOG OUT 1 (%) (monitor)
The output at terminals 16 and 17. 0% is 4 mA, 100% is 20 mA.
11 LOAD SIGNAL (Vdc) (monitor)
The generator kW converted to load gain volts.
G**SPEED SETTINGS**
Speed settings are the parameters that affect the prime mover speed reference.
01 START SPEED (RPM) dflt = 400.00 (1.00
–2100)
The initial speed reference for the speed control before starting. Start speed must
be set above cranking speed and below the speed achieved with the start fuel
limit setting (light-off speed). A ramp from start speed to idle or rated, whichever
is selected, begins when the engine accelerates to start speed. The ramp time is
the accel ramp time setting, when going to the rated speed setpoint. The ramp
time is the decel ramp time setting, when going to the idle speed setpoint.
02 RAISE SPEED LIMIT (RPM) dflt = 1000.00 (0.00
–4000.00)
The maximum speed reference setting when the raise switch is closed. It is
normally set at the speed at which the engine operates at full load if the Droop
mode is used, or at the high limit of the speed trim function.
03 LOWER SPEED LIMIT (RPM) dflt = 800.00 (0.00
–4000.00)
The minimum speed reference setting when the lower switch is closed. It is
normally set at the minimum operating speed of the engine, or at the minimum
limit of the speed trim function.
04 IDLE SPEED (60 HZ) (RPM) dflt = 600.00 (0.00
–4000.00)
This is the speed that the speed reference ramp goes to when the close for rated
discrete input is OPEN. It is normally the speed at which the engine is operated
at start-up. It is also used during cool down. The idle speed is limited to 90% of
Rated Speed
05 IDLE SPEED (50 HZ) (RPM) dflt = 450.00 (0.00
–4000.00)
This is the speed that the speed reference ramp goes to when the close for rated
discrete input is OPEN and a Discrete Input is configured for 50/60 Hertz
Operation. It is normally the speed at which the engine is operated at start-up. It
is also used during cool down. The idle speed is limited to 90% of Rated Speed
Idle Speed is limited to a value between synchronous speed entered
in configure and 20% of synchronous speed (a 5 to 1 speed range).
Avoid critical speeds when setting idle speed.
06 ACCEL RAMP TIME (SEC) dflt = 20.00 (1.00
–300.00)
The time required for the control to ramp the engine speed from idle speed to
rated speed. The ramp is started whenever the Idle/Rated contact is closed.
