SP 0.1, SPR 0.1

The procedure is as follows

Press the button

SW1

for about 2 sec (i.e. till the

diode is got on) to set the controller to the

autocalibration

mode. During this process the controller checks the feedback transmitter and the

sense of turning, puts the EA to the positions open and closed, measures inertia mass in the directions
"opening" and "closing", and loads the adjusted parameters into the EEPROM memory. In case that
during the initialisation process an error occurs (e.g. in connection or adjustment) the initialisation
process will be interrupted and the controller with the

diode reports about the type of the error. Else

after finishing the initialisation process the controller is put into the

regulation mode

. If needed to

change adjusted parameters of the controller follow instructions given in the part Adjusting of actuator.

2.2 Dismantling

Before dismantling it is required to disconnect the EA from mains!
Do not connect and disconnect live connectors!

•

Disconnect the EA from mains.

•

Disconnect the leads from the EA terminal boards and loosen the cables from cable glands.

•

Loosen the fixing screws of the EA flange and disconnect the EA from the valve.

•

While sending the EA to be repaired put it into a package solid enough to avoid damages of the EA

during transportation.

3. Adjusting of actuator

Attention!

See chapter 1.2.2 Requirements for professional qualification …

Disconnect the electrical servo-drive from electrical power network!

Observe safety regulations!

The adjustment can be performed at a mechanically and electrically connected EA. This part

describes adjustment of EA to specified parameters in case that any unit of EA is reset. Laying of
adjusters of the control board is shown on Fig.1.

The control parts designed for adjustment are accessible after removing of the actuator upper

cover. Unscrew the four screws fixing the cover to the bottom case, and remove the cover.

After adjustment fix again the cover with the four screws. While placing the cover onto the

actuator have the position unit shaft fitting in the pointer shaft recess. Having the cover on and the
screws tightened adjust the pointer in accordance with the Chapter 4.6.

3.1 Output position changes

In the plant the end positions of the actuators are adjusted in accordance with the dimensional

drawings. If while the mechanical disengagement in accordance with the Chapter 2.1 the adjustment
does not meet the requirements, it is needed to turn the fixed operation angle 60°, 90°, 120° or 360°
by any value (in the limit position "closed"). While output position changing it is needed to adjust the
actuator in accordance with the Chapters 3.2 to 3.7.

If during the adjustment the actuator stops after switching-off the end switch S4 before the

required position, it is needed to turn the cam V4 counter-clockwisely until the required limit position
"closed" is set (Chapter 3.2).
