3.1 Mechanical Switch Mechanism

Test Feedback Switches

1) Confirm the torque or limit switches are functional by

monitoring feedback on the Atronik status indicators

during switch testing.

The main power supply must be maintained

during this test procedure to ensure feedback

viatheAtronik.

It is not possible to test a switch that is already actuated

by the mechanism (for instance, at the end of travel

limits). To ensure that all switches can be tested correctly,

move the actuator to a mid-travel position and confirm

that none of the switches are active before beginning the

test procedure.

2) Test position switches in both directions using a flat

screw-driver to turn LS TEST. Clockwise (CW) for open

and anti-clockwise (ACW) for close.

The applicable status indicator will illuminate when the

switch is active. Verify that mid-travel is illuminated prior

to testing the switch status.

3. Commissioning

Test Feedback Switches

3) Test torque switches in both directions using a flat

screwdriver to turn TS TEST (ACW for open, CW for

close).

Torque switch status is shown via the fault indicator. Fault

should illuminate when the torque switch is engaged in

either direction.

A 5 mm Allen (Hex.) key and 0.8 x 4 mm flat screwdriver are

required to perform commissioning of the CK Mechanical

Switch Mechanism.

Set torque limits

A Indicator/Adjustment Point

B Torque Cam Clutch Screw

1) Move the valve to a mid-travel position and loosen the

Torque Cam Clutch 1.5 turns using a flat screwdriver.

2) Adjust each Torque Cam to the desired value (between

min. & max.) by moving the cam using a screwdriver on the

adjustment point.

CAUTION: Ensure the screwdriver remains

perpendicular to the switch mechanism faceplate

when adjusting the torque trip limits to avoid

introducing an offset to the set value.

3. Commissioning

COpen Torque Adjustment Point

DClose Torque Adjustment Point

3) Tighten the Torque Cam Clutch Screw once both torque

trip limits have been set.

CAUTION: Ensure the Torque Cam Clutch Screw is

tightened enough to fully deform the spring washer

underneath the screw head.

EFactory Calibration Fixings

WARNING: Do not adjust the fixings or position

of the yellow torque indicator plates. These are

factory configured for 40-100% adjustment of the

actuator torque and under no circumstances should

be moved.

1) Move actuator to the valve CLOSED position using

handwheel operation.

2) Using a flat screwdriver, depress the Drive Clutch Shaft

and rotate to “SET” position as shown on the switch

mechanism faceplate.

3) The CLS Adjustment Screw must now be rotated to

make the closed limit switch inside the switch mechanism.

The CLS Indicator Window will show one of four

possible symbols. Please refer to Figure 1 on page 7

fordirectioninput.

4) Depending on where the mechanism is in the cycle, it

is possible that the switch will be approached from the

wrong direction, in which case it is necessary to move

through the limit and approach it from the correct

direction. This is done to avoid the need to wind through

the whole mechanism to reach the limit position. The

correct direction to approach the limit is shown by the

arrow next to the Adjustment Screw input.

5) Perform two checks to confirm the CLOSED limit position

switch has been made correctly.

a. The feel of the Adjustment Screw will noticeably

change providing more mechanical resistance at the

switching point of the contact.

b. Confirm the switch has been made by checking the

CLOSED limit indicator is illuminated on the Atronik.

6) Using a flat screwdriver, depress the Drive Clutch Shaft

and rotate to “RUN” position as shown on the switch

mechanism faceplate.

7) Rotate the CLS and OLS Adjustment Screws a small

amount in both directions to re-engage the mechanism

drive. A click will be heard as the drive drops back into

engagement and the adjustment screws will no longer

move in either direction.

Step 7 must be done or the limit will be lost when the

actuator is moved.

Test Feedback Switches

3) Test torque switches in both directions using the TS TEST

lever shown on the left side of the unit between the AID

module and Mechanical Switch Mechanism (move DOWN

for open, UP for close).

Torque switch status is shown via the fault indicator. Fault

should illuminate when the torque switch is engaged in

either direction.

3.2 Additional Indication Drive

The Additional Indication Drive (AID) supplements the

mechanical switch mechanism to increase functionality.

Test Feedback Switches

1) Confirm the torque or limit switches are functional by

monitoring feedback on the Atronik status indicators

during switch testing.

The main power supply must be maintained

during this test procedure to ensure feedback

2) Test position switches in both directions using the LS TEST

lever shown on the right side of the unit between the AID

module and Mechanical Switch Mechanism (move DOWN

for open, UP for close).

The applicable status indicator will illuminate when the

switch is active. Verify that mid-travel is illuminated prior to

testing the switch status.

Setting Local Position Disc

The AID module includes a Local Position Disc that should be

configured to show Open and Close limit positions. A series

of reduction gears ensure a suitable range of travel can be

accommodated. If more turns are required please contact

Rotork.

CAUTION: The actuator position limits must be

configured prior to setting the Local Position Disc.

CAUTION: The AID cover orientation can be

adjusted through 360º in 90º increments. If this is a

requirement then the following instructions must

be adjusted by the same increment in the same

direction.

1) Move the actuator to the CLOSED limit using electrical

operation or the handwheel.

2) Loosen off the Position Disc Retaining Screw by 1 turn.

3) Rotate the Position Disc so that CLOSE reads horizontally

and hold the disc in place.

4) Tighten the Position Disc Retaining Screw until the Position

Disc is firmly locked in place.

5) Confirm the CLOSE label is aligned correctly with the cover

indication arrow.

7) Loosen off the Position Disc Retaining Screw by 1 turn

whilst holding the CLOSE portion of the Position Disc.

8) Rotate only the red OPEN portion of the disc so that OPEN

reads horizontally and then hold both portions in place.

9) Tighten the retaining screw until the Position Disc is firmly

locked in place.
