10 AUTO RAISE DELAY:
[*120 (0,600)] When the unit is started, the gate limit goes to the “Breakaway”
gate limit and is held there for a specified time. Then the gate limit ramps to the “Speed-No-Load” gate
limit, and stays there until the generat
or breaker is closed. If the “Speed-No-Load” gate limit is set too low,
the unit will not be able to synchronize. If the “AUTO RAISE DELAY” timer expires, the 2301E-HT will
automatically start ramping the gate limit up. This timer set point is in seconds.
11 AUTO RAISE RATE:
[*0.5 (0,100)] This menu item defines the rate at which the “AUTO RAISE”
function raises the gate limit. See previous menu item.
12 MAN R/L RAMP RATE:
[*2 (0.01,100)] This menu item defines the rate at which a manual gate limit
“RAISE” and “LOWER” adjust the gate limit.
12 VALVE DRIVER (I)
This menu contains items related to the integrating valve driver. It shall be used only if an integrating
valve driver controls the hydraulic turbine.
01 ACTUATOR DEMAND:
[MONITOR] This menu item displays 2301E-HT digital c
ontrol’s actuator/ gate
“demand.” The units of this menu item are in percent (%) gate position.
02 VALVE OFFSET:
[*0 (-100,100)] This menu item defines the valve offset for the integrating actuator. It
is used to adjust the null current of the actuator.
03 OFFLINE VALVE GAIN:
[*1 (0,50)] This menu item defines the valve gain for the integrating actuator
when the generator breaker is opened. It is used to tune the response of the actuator.
04 ONLINE VALVE GAIN:
[*1 (0,50)] This menu item defines the valve gain for the integrating actuator
when the generator breaker is closed. It is used to tune the response of the actuator.
05 DITHER FREQUENCY:
[*2 (1,5)] This menu item defines the dither amplitude frequency.
06 DITHER FREQUENCY:
[MONITOR] This menu item displays the dither frequency that is being used.
07 DITHER AMPLITUDE:
[*0 (0,100)] This menu item defines the dither amplitude, in %.
13 GATE VALVE DRIVER (P)
This menu contains items related to the proportional valve driver.
01 ACTUATOR DEMAND:
[MONITOR] This menu item displays the 2301E-HT digital c
ontrol’s actuator/
gate “demand.” The units of this menu item are in percent (%) gate position.
14 MANUAL AND MAINT
This menu contains items related to the gate Manual and Maintenance modes available in the 2301E-HT.
01 MANUAL MODE ENABLED:
[MONITOR]
02 ENABLE MAINT MODE:
[TRUE or *FALSE] This menu item activates/ enables MAINTENANCE
mode in the 2301E-HT when the value is tuned to TRUE.
03 PRESET VALUE:
[*0 (-10,110)] This menu item defi
nes a “preset” gate position. The units of this
value are in gate position percent (%).
04 GOTO PRESET VALUE:
[TRUE or *FALSE] This menu item forces the demand to the preset value
(the previous menu item).
15 OFFLIN/ISOCH CTRL
This menu contains items related to off-line and isochronous control.
01 OFFLINE/ISOCH REF:
[MONITOR] This menu item displays the off-line or isochronous speed
reference.
02 I'M IN CONTROL:
[MONITOR] This menu item displays a TRUE when the off-line or isochronous
algorithms are in control of the unit.
03 PID OUTPUT:
[MONITOR] This is the actuator demand from the off-line/ isochronous PID algorithm.
04 RAISE/LOWER RATE:
[*0.01 (0.001,100)] This menu item defines the rate at which the off-
line/isochronous RAISE and LOWER commands adjust the speed reference.
05 SPEED-NO-LOAD REF:
[*100.05 (75,125)] This menu item defines the speed reference that the
2301E-HT uses when it initially starts the unit. It should be tuned as close to the synchronous speed
reference for normal conditions.
06 UPPER LIMIT - REF:
[*110 (75,250)] This menu item defines the upper limit of the off-line/isochronous
speed reference.
