Closing Speed Limit: Used to reduce the speed of the close valve movement.
This parameter will change the value of
TRAVEL_RATE_INC for a value equal to one of the
following options:
-
Slowest
: 20% Dynamic Speed;
-
Slow
: 40% Dynamic Speed;
-
Normal
: 60% Dynamic Speed;
-
Fast
: 80% Dynamic Speed;
-
Fastest
: 100% Dynamic Speed;
-
Custom
: Uses the travel rate defined in the Travel Time CLOSE
filed (TRAVEL_RATE_INC parameter).
Pressure Unit: Engineering unit for the pressure sensor’s value.
Supply Pressure: Pressure sensor value - reserved for future use. (The
current manifold has pressure sensor only on one output
- port A).
Pressure Port A: Pressure of manifold output port A - It is located in the
port A. Its unit is defined in the PRESSURE_UNITS.
The accuracy over the span is ± 2% between 0 - 50ºC.
The offset has a variation of 3.5% for each 1ºC of
variation.
If the unit is %, then 100% is the maximum pressure used
in the calibration.
Pressure Port B: Pressure of manifold output port B - reserved for future
use. (The current manifold has pressure sensor only on
one output - Port A)
Internal Temp Unit: Engineering unit for the electronic board temperature
sensor.
Internal Temperature: Electronic board temperature in units as defined in the
INTERNAL_TEMP_UNIT parameter.
Transducer Command: A selection of calibration procedures, which are executed
by pressing the “Execute” button. The procedures are:
- No reaction of the field device;
- ARM;
- Self-calibration;
- Hall sensor gain calibration;
- Low position calibration;
- High position calibration;
- Transducer calibration;
- Servo PID tuning.
Transducer Command
State:
Current calibration state.
Enable Alert: This parameter can be used to enable the available alerts
separately.
Alert Status: Shows the alerts enable that is ON in the moment.
Reset Counters: This parameter will reset all counters used for alert or
reset each counter separately.
Total Travel Deadband: In units of TRAVEL_COUNT, this parameter will setup a
dead band to assume that the valve is totally open or
