b. Send a value of 1 to register 40043. Valve plug will move to fully open position and then to fully closed. The valve
plug will then return to the commanded position.
If a Modbus connection is not available, and recalibration is desired, use the appropriate calibration method as
determined by the control method of your valve.
Calibration without the use of Modbus
1. Turn power to the actuator off.
2. Wait for 10 seconds to ensure all circuits have discharged.
3. Return power to the actuator and use the appropriate calibration method for your control signal. Calibration
sequence must be done within 15 seconds of power being switched on.
4. For On/Off operation using L2e dual­input dry contact:
a. Close the contact to create a short between pins COMMON and OPEN – valve plug will not move at this time.
b. Close the contact to create a short between pins COMMON and CLOSE – valve plug will move to the upper, open
position and then to the lower, closed position.
5. For On/Off operation using single dry contact:
a. Close the contact to create a short between pins COMMON and OPEN – valve plug will not move at this time.
b. Open the contact to create an open circuit between pins COMMON and OPEN – valve plug will move to the
upper, open position and then to the lower, closed position.
6. For positioning operation using 4­20mA:
a. Apply a 20mA signal between pins 4-20mA - and 4-20mA + – valve plug will not move at this time.
b. Apply a 4mA signal between pins 4-20mA - and 4-20mA + – valve plug will move to the upper stop, immediately
followed by moving to the lower, closed position.
c. If calibration of the analog input is desired to improve positional accuracy, an optional operation is listed in the
next section titled Analog Input Calibration.
7. The uint is now calibrated.

The Gen 2 easy-Drive actuator has two differing modes of operation: On/Off and Positioning. The On/Off mode is
intended for snap-acting applications where the valve is either fully open or fully closed. In this mode, the valve plug
cannot remain at any intermediate position; it will move to a fully closed or fully open position only. For applications
that require the actuator to control over the full range of motion, it is necessary to have a Positioning license installed.
A positioning license will allow access to 4-20mA positioning, 4-20mA level control and Modbus positioning.
Positioning licenses can be purchased with the actuator and installed at the factory or can be installed at a later date by
use of a license key on a USB license dongle. Installation of the license can be completed using the configuration
software.
1. Insert the USB license dongle into the computer connected to the Gen 2 easy-Drive actuator.
