2301E-HT Hydro (Francis Turbines)
Woodward
50
05 GOTO 95% GATE POS:
[TRUE or *FALSE] This menu item forces the gates to 95% when the 2301E-
HT is in manual control mode.
22 STEP TEST
This menu contains items related to the Step Test function in the 2301E-HT digital control.
01 ENABLE STEP TEST:
[TRUE or *FALSE] This menu item enables/activates the step test. Be aware
that this will induce a step change in the speed reference when this value is tuned from FALSE to TRUE.
This step change steps the gate position demand directly when in manual or maintenance mode.
02 STEP DURATION:
[*30.0 (0.0, 1200.0)] This menu item defines the duration of the step change in the
speed reference (or gate position demand when in manual or maintenance mode). Once this time has
expired, the step test must be disabled and then enabled again to repeat the test.
03 STEP VALUE (%):
[*3.0 (-10.0, 10.0)] This menu item defines the amplitude of the step change. The
units of the step change are in speed reference percent (%) when in speed control, and they are in gate
position percent when in manual or maintenance mode.
04 NEGATIVE STEP?:
[TRUE or *FALSE] This menu item, when tuned to TRUE, makes the step change
negative.
23 BRAKES
This menu is only applicable when the Brake Permissive function is enabled in the FUNCTION SELECT
menu in the Configure mode (only when programming using Hand Held Programmer). This menu
contains items related to the Brake Permissive function.
01 BRAKE PERMS MET:
[MONITOR] This menu item displays TRUE when the brake permissives have
all been met.
02 BRAKE ENABLE SPD:
[*50 (0,100)] This menu item defines the speed at which the brakes can be
enabled.
03 BRAKE ENABLE GPOS:
[*2 (0,100)] This menu item defines the gate position at which the brakes
can be enabled. This value should be set slightly higher than 0 to allow for gate position transducer
drifting.
04 BRAKE ON TIMER
[*60 (0, 10000)] This menu item defines how long the brakes will be applied once
all permissives have been met.
05 BRAKE ON PULSE TIME
[*15 (0,10000)] This menu item defines the on time pulse once the brakes
permissives are met and the brakes are applied.
06 BRAKE OFF PULSE TIME
[10 (0,10000)] This menu item defines the off time pulse once the brakes
permissives are met and the brakes are applied. S
et this value to “ 0 “ for Brakes to be in a steady ON
state.
24 CREEP
This menu contains items related to the Creep Detection function.
01 UNIT CREEPING?:
[MONITOR] This menu item displays TRUE when a unit creep is detected.
02 CREEP SPEED (%):
[*5 (0,10)] This menu item defines the speed at which the control starts the Dead
Stop timer.
03 DEAD STOP (SEC):
[*60 (10,600)] This menu item defines the normal time between the creep speed
(previous menu item) and a dead stop.
04 RESET CREEP (SEC):
[*5 (0,600)] This menu item defines the time, in seconds, the control waits
before it automatically resets the creep detection.
05 LOOK AGAIN (SEC):
[*5 (0,600)] This menu item defines the time, in seconds, the control waits
before it starts looking for creep again.
25 MODBUS
This menu contains items related to the Modbus communication.
01 BAUD RATE:
[*10 (1,12)] This menu item defines the baud rate for the Modbus communications.
1=110 / 2=300 / 3=600 / 4=1200 bps / 5=1800 bps / 6=2400 bps / 7=4800 bps / 8=9600 bps / 9=19200
bps / 10=38400 bps / 11=57600 / 12=115200
02 STOP BITS:
[*1 (1,3)] This menu item defines the stop bits for the Modbus communications. 1=1 Stop
Bit / 2=1.5 Stop Bits / 3=2 Stop Bits
