4.16.1 APT Polarity Option
The APT option provides a 4-20 mA feedback signal proportional to valve position. APT is connected at terminals 17
and 18 for 4-20 mA output. Consult actuator wiring diagram for details.
NOTE: If the second analog out option is turned ON but this option was not purchased, the display will show a hardware
fault. An optional I/O board is required for this option. To purchase, please contact Limitorque service coordinator at
(434) 528-4400.
During position limit calibration (see Section 3.5.4, Setting Position Limits) the APT is automatically calibrated to
default settings: Default = 20 mA OPEN, 4 mA CLOSE.
To Customize the Settings:
1. Select “CHANGE APT?” from the “SETUP” routine. Select “YES.”
2. Select “NO” to select the status if OFF. If ON, select “YES” to enter the “Status Function APT?” display. Select “NO”
to select ATT display.
