Transducer Block Parameters Description
Subparameter POSITION Predetermined user-configured emergency shutdown target
position. Range 0 to 100%.
Subparameter ACTIVE_SIGNAL Active emergency shutdown signal. Value 1=Network ESD,
2=Local ESD and 3=Both ESD.
PST Record supports implementation of partial stroke test for the
device.
Subparameter COMMAND This parameter is used to pass the PST commands to the
device. Value 1=Start PST and 2=Stop PST.
Subparameter
TARGET_POSITION
PST target position value scaled to 100. Range 0 to 1000.
Subparameter STATUS PST staus, value 0=Not started, 1=In progress, 2=Completed,
4=Stopped.
Subparameter RESULT PST result, value 0=Not started, 1=Awaited, 2=Passed, 4=Failed.
Subparameter
MAXIMUM_TORQUE
Maximum torque recorded during PST execution, value range
0 to 100%.
TORQUE Record provides support for actuator torque configuration.
Subparameter CLOSE_SETTING The torque limits in the close direction are configured from 40
to 100% of the rated torque in the increments of 1%.
Subparameter OPEN_SETTING The torque limits in the open direction are configured from 40
to 100% of the rated torque in the increments of 1%.
Subparameter BOOST Torque boost is to prevent torque trip during initial valve
unseating and in cold climates. Value 1=On, 2=Off and 4=Auto.
Subparameter OUTPUT Torque sensor derives output from motor speed, temperature
and voltage. Range: 0 to 100%.
ACT_TYPE Actuator type. Value 16=MX, 96=QX, 144=MXa, 160=UEX and
176=QXM.
ACT_SERIAL_NUMBER Actuator serial number.
QA_STAMP QA stamp.
CONTROL_MODE The actuator can be configured for continuous position control
or Open/Close operations.
Subparameter TARGET In Position control mode, the actuator moves the valve to the
setpoint value. In Open/Close control mode, the actuator moves
the valve to 100% position if setpoint is greater than or equal
to 50% and moves to 0% if setpoint is less than 50%. Value
1=Close/open and 2=Position.
Subparameter ACTUAL Actual control mode in which actuator is functioning. Value
1=Close/open and 2=Position.
DTM_HEART_BEAT DTM writes hear beat every 30 seconds. The actuator moves
the DTM_OPERATION to DTM_READ_ONLY if it does not
receive hear beat for 120 second.
