The procedure is as follows
Press the button SW1 for about 2 sec (i.e. till the D3 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
D4 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 on professional competence…
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.
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.
3.1 Adjustment of position switches (Fig.4)
In the plant the actuators are adjusted to the fixed angle (90
°
, 120
°
or 160
°
) in accordance with the
name plate. While adjusting follow these steps:
• Set the actuator to the end position "closed" and turn the cam (13) clockwisely until the switch S4
(18) will switch. Adjust also the additional position switch S6 (20) turning the cam (15) in the same
direction as the cam (13) for the switch S4.
• Set the actuator to the position „open“ and turn the cam (12) counterclockwisely until the switch S3
(17) will switch. Adjust also the additional position switch S5 (19) turning the cam (14) in the same
direction as the cam (12) for the switch S3.
Legend
12 ..... cam of switch S3
13 ..... cam of switch S4
14 ..... cam of switch S5
15 ..... cam of switch S6
17 ..... position switch “open”
18 ..... position switch “closed”
19 ..... additional position switch “open”
20 ..... additional position switch “closed”
Note:
The position switches of the actuator with the position transmitter can be set in connection with the
range possibilities of the transmitter.
