Specifi cations/Defi nitions
Service Parameter Variables Description
Displays
Identifi cation
Serial Number Displays the actuators internal serial number.
Actuator Type / Software Version Displays the actuator nomenclature (AFX24-MFT US) and MFT software version.
Assembly Location Displays the where the actuator was assembled.
Setpoint Displays the actual control input position as a percentage. As signal input
changes you will see the setpoint percentage change accordingly.
Actual Values
Actual Position Displays the actual position as a percentage. As the setpoint changes the
actual position percentage will increase or decrease accordingly. If the
actuator is capable of rotating the damper or valve, this can be of benefi t
when troubleshooting an application.
Function
Control Type & Setting Displays the actual control type and operating range.
Feedback Type & Setting Displays the actual feedback signal type and operating range.
Torque % Setting Displays the actual torque setting, as a percentage of minimum torque.
Running Time Displays the actual running time as programmed in seconds.
Direction of Rotation Displays the status of the direction of rotation option (Normal or Reversed).
Min, Mid, Max Position Displays the actual position setting of the Intermediate position control.
Adaptation Displays the actual setting of the adaptation function (OFF, ON-Manual, ON-
Automatic).
Sensitivity / Hysteresis Displays the actual setting of the sensitivity (Normal or Reduced).
Synchronization Displays the actual setting of the synchronization function (Normal, Sync at
0%, Sync at 100%).
Data Log
Total Time / Operating Time Total number of hours the actuator is connected to a power supply.
Active Time Total number of hours the actuator is in motion.
Stop / Go Ratio (Hunting %) Displays a percentage the total number of hours the actuator has spent in
mechanical motion, comparing the total time to the active time.
Sensitivity
Normal, Reduced Displays the setting of the sensitivity function.
Functions
Messages
Displays all messages present. Messages can be deleted as well.
Function Test
This function enables you to check for complete opening and closing of the
actuator.
The test report contains:
• Information on the Project
• Identifi cation on the Actuator
• A list of fault messages pending before the start of the test
• The test steps and results
• The current actuator settings
This is of benefi t when troubleshooting an application, as the actuator
will drive the damper or valve. This gives an opportunity to observe the
installation to identify any possible problems.
Adaptation See Adaptation on page 13.
Initiates the adaptation feature of the MFT actuator. The actuators working
range (input, feedback, and running time) will be adapted to the actual angle
of rotation.
This is of benefi t when troubleshooting an application, as the actuator will
drive the damper or valve. This gives you an opportunity to observe the
installation to identify any possible problems.
Synchronization
Normal At initial commissioning, when the manual override button is pressed, the
actuator runs to a default position defi ned by the position of the CW/CCW
direction of rotation switch.
Sync at 0% At each power-up (includes power failures), the actuator runs to a default
position defi ned by the position of the CW/CCW direction of rotation switch.
Sync at 100% At each power-up (includes power failures), the actuator runs to a default
position of the CW/CCW direction of rotation switch.
