9.3.2.4 Units
A sub directory of Parameters/Transducer, it has a group to configure the engineering
units used to display the readings of the device's sensors.
Position Unit: Engineering unit for the position, defined in the AO.PV_SCALE
parameter.
Working SP: Process variable from the analog output block after
characterization, FLOP and reverse acting (SIGNAL_ACTION) in
POSITION_UNITS
Working Position: Hall sensor value in engineering unit defined in the
POSITION_UNITS 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.
9.3.2.5 Valve and Actuator Info
A subdirectory of Parameters/Transducer, it contains a group of parameters that allows
the user to configure the type and information of the valve and actuator setup.
