Badger Meter SRD/SRI Valve Positioners - Manual (Page 45)

5.7 Setting Lower Alarm
- 1 1 - - LED 1 and LED 2 lights up
When falling below the set value underneath the entered alarm limit, an
alarm is activated. Message 12 is generated.
To switch off the alarm setting, enter the value –10%.
5.8 Setting Upper Alarm
- - 1 - 1 LED 2 and LED 4 lights up
When surpassing the set value above the entered alarm limit, an alarm is
activated. Message 13 is generated.
To switch off the alarm setting, enter the value +110%.
By pressing of keys ( +) or (–), the value is adjusted and with key ( ) confirmed.
The keys have Autorepeat: By pressing and holding of a key (+) or (–) , the value is counted
upward, after some time in larger steps.
Example: Upper Alarm set to 91.3 %.
5.9 Valve Limits (Not with versions FF/PB/FoxCom with LED display)
At Autostart the SRD determines the real limits of the actuator (which
generally are a little larger then specified on the specification sheet). An
actuator with 30 mm stroke, could display a real stroke of 33 mm. In order
to produce a precise relationship between the input signal and the stroke,
the tolerances of the actuator can be compensated with menus 5.9 and
5.10. At unchanged 0 %, the actuator could be moved until exactly 30 mm
are reached. Through execution of function 5.10, the current position can
be declared as 100 % and at a setpoint value of 50 %, the actuator will run
on exactly 15 mm.
For new configuration of the strokes at 0% or 100%, the valve must be run
in the corresponding position and then must be confirmed.
5.9 Setting Valve 0 %
- 1 1 - 1 LED 1, LED 2 and LED 4 lights up
The actual position of the actuator is declared as 0 %.
5.10 Setting Valve 100 %
- - 1 1 1 LED 2, LED 3 and LED 4 lights up
The actual position of the actuator is declared as 100 %.
By pressing of keys ( +) or (–), the value is adjusted and with key ( ) confirmed.
The keys have Autorepeat: By pressing and holding of a key (+) or (–) , the value is counted
upward, after some time in larger steps.
Example: The actual valve position 98.4 % is to be counted as 100 %.
5.11 Setting Stroke with stroke actuators (only with LCD)
- - 1 1 - (LED 2 and LED 3 lights up
The SRD measures with its feedback lever always only an angle and by
means of its tangent function, a linear stroke of 0 to 100 % is calculated
therefrom. In order to indicate as well a real stroke in mm, the full stroke at
100 % can be entered in this menu. The LCD display will then indicate the
actual position in mm/inch.
(Changing of display to “inch” via communication.)
By pressing of keys ( +) or (–), the value is adjusted and with key ( ) confirmed.
The keys have Autorepeat: By pressing and holding of a key (+) or (–) , the value is counted
upward, after some time in larger steps.
Example: Stroke range of valve is to be 30 mm.
