Calibration Instructions

WARNING

To avoid personal injury or property damage, be aware that the valve will open fully and then close fully during the

calibration cycle.

It is not necessary to calibrate y our easyDrive electric actuator prior to use from a factory shipment.

If any of the following are true, recalibration will be required (see next section)

D The actuator has been remounted o n a different valve since shipment

D Disassembly of the valve for trim or packing changes

D A new version of firmware has been loaded on the controller

The following scenarios do not require recalibrations

D New unit from the box

D Power dips or interruptions

D Changi ng of control method (i.e. from 420mA to Modbus control)

D Extended periods of storage

Calibration with the use of Modbus

1. After the unit has been properly wired and fused per instructions in the Wiring section of this instruction manual,

turn power to the unit on.

2. Calibrate using Modbus:

a. Send position command of 0% to actuator to prevent unexpected motion. Valve will move to commanded

position following the calibration procedure.

b. Send a value of 1 to register 40003. Valve plug will move 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
