15 SPEED SS1 FILTER:
[*0.01 (0.0,10)] This menu item is the time constant for the Lag Tau filter used to
filter the speed input #1 signal. When this number is tuned to 0.01, then the filter is basically turned off. It
is recommended that this value remain at 0.01 unless noise problems are present on the speed #1 signal.
16 SPEED SS2 FILTER:
[*0.01 (0.0,10)] This menu item is the time constant for the Lag Tau filter used to
filter the speed input #2 signal. When this number is tuned to 0.01, then the filter is basically turned off. It
is recommended that this value remain at 0.01 unless noise problems are present on the speed #2 signal.
10 GATE POSITION
This menu contains items related to Gate Position control.
01 GATE POSITION:
[MONITOR] This menu item displays current gate position.
02 VALUE @ 4 mA:
[*0,(-200,200)] Defines the value when the current is 4 mA
03 VALUE @ 20 mA:
[*100,(-200,200)] Defines the value when the current is
20 mA
04 USE SML MISMATCH:
[*TRUE or FALSE] This parameter defines if the Small Gate Mismatch alarm
is going to be used.
05 SML MISMATCH WIN
: [*3 (1,10)] This menu item defines the size of the “Small Mismatch” window.
The units are in gate position percent.
06 SML MISMATCH TIM:
[*10 (0,60)] This menu item defines the time, in seconds, the control waits
before issuing a “Small Mismatch” alarm.
07 USE LRG MISMATCH:
[*TRUE or FALSE] This parameter defines if the Large Gate Mismatch alarm
is going to be used.
08 LRG MISMATCH WIN:
[*5 (1,10)] This menu item defines the size of the “Large Mismatch” window.
The units are in gate position percent.
09 LRG MISMATCH TIM:
[*10 (0,60)] This menu item defines the time, in seconds, that the control waits
before issuing a “Large Mismatch” shut down.
10 GATES CLOSED %:
[*2 (0,5)] This menu item defines the gate position at which the 2301E-HT
considers the gates to be closed. It is recommended that this number be above zero to allow for slight
drifting in the gate position transducer.
11 GP SIG FILTER TC:
[*0.01 (0.001,5)] This menu item is the time constant for the Lag Tau filter used to
filter the gate position signal from the transducer. When this number is tuned to 0.01, then the filter is
basically turned off. It is recommended that this value remain at 0.01 unless noise problems are present
on the gate position signal.
11 GATE LIMIT
This menu contains items related to the gate limit function.
01 GATE LIMIT:
[MONITOR] This menu item displays the current gate limit.
02 GATE LIMIT COINC.:
[MONITOR] This menu item displays the condition when gate limit is equal to
the gate position. TRUE means that the gate limit equals the gate position.
03 ANALOG IN LIMIT ALL TIME:
[TRUE or *FALSE] If this value is set to FALSE then the analog gate
limiter will be evaluated only when the unit in online. If this value is set to FALSE then the analog gate
limiter will be evaluated all the time.
04 ANALOG IN @ 4 mA:
[*0 (0, 100)] This value represents gate limiter value (in percentage) if the
analog input is equal to 4 mA.
05 ANALOG IN @ 20 mA:
[*100 (0, 100)] This value represents gate limiter value (in percentage) if the
analog input is equal to 20 mA.
06 BREAKAWAY GL:
[*30 (0,100)] This menu item defines the “Breakaway” gate limit used during
startup of the unit. This value should be set to the gate position it takes to break the unit away from its
stopped position.
07 HOLD@BRKAWY TIME:
[*1 (0.001,30)] This menu item defines the time, in seconds, that the gate
limit stays at the “Breakaway” position before it starts ramping toward the “Speed-No-Load” gate limit.
08 SPEED-NO-LOAD GL:
[*15 (0,100)] This menu item defines the “Speed- No-Load” gate limit used
during startups and load rejections. This value should be set slightly higher than the actual Speed-No-
Load gate position.
09 PREPOS ONLINE GATE LIM:
[*100 (0,100)] This menu item defines the “Maximum On-Line Gate
Position
.” This value will pre-position the gate limit to this valve once the breaker closes. Once on-line, for
example, if the pre-position value is set to 80% and the gate limit is at 75%. If a gate limit raise command
is issued, the gate limit will raise until it reaches 80%.
