The ATT option provides a 4-20 mA signal proportional to actuator output torque and is for reference only. The signal
range is from approximately 40% of rated torque to approximately 100% rated torque. This option is connected at
terminals 17 and 18 for 4-20 mA output. Consult the 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

4.17 Remote Mode
Remote mode permits a User to select from multiple remote control permissions, or isolate remote control to a single
control selection:
• Multi Control mode (default): permits up to three discrete remote inputs: There are three modes of remote control for
the QX actuator allowed when the remote mode is configured for multi-control: digital control, analog control, and
network control. Digital and network control operation is based on the last command received. Analog control opera-
tion in initiated by either toggling user input 2 (configured for CSE input) or breaking and reapplying the analog signal.
• Digital Control Only: the unit will operate only upon the last digital input command received.
• Network Control Only: the unit will operate only upon the last network command received.
• Analog Control only: the unit will operate only upon the last analog input command received.
