CK Mechanical Switch Mechanism – Switch Testing
Before following any of the setting instructions included in this
document it is important to pay attention to the warnings and
safety instructions included in PUB111-007 provided with the
actuator.
A 5mm Allen (Hex.) key and 1.0 x 5.5mm flat screwdriver are
required to perform testing of the CK Mechanical
Switch Mechanism.
Test feedback switches
WARNING: Isolate the main power supply and all control
and indication wiring before removing the Plug & Socket
cover.
1) Undo the four retaining cap screws on the switch mechanism
cover and remove the cover to show the switch mechanism.
2) Confirm the torque or limit switches are functional by
measuring the relevant feedback terminals on the plug
assembly (see below).
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.
3) Test position switches in both directions using a flat screwdriver
to turn LS TEST (CW for open, ACW for close).
4) Link a continuity meter across the following pairs of terminals to
test each individual function.
N/C CLS – Normally Closed (break when active) Close Limit contact
for motor control
N/O CLS – Normally Open (make when active) Close Limit contact
for feedback indication
N/C OLS – Normally Closed (break when active) Open Limit contact
for motor control
N/O OLS –Normally Open (make when active) Open Limit contact
for feedback indication
INFO: It is important to recognise the rotation of the
exposed plug when performing actuator function
diagnostics. The central “U” locating point provides an
orientation reference for this testing procedure.

CK Mechanical Switch Mechanism – Basic Settings
A 5mm Allen (Hex.) key and 0.8 x 4mm flat screwdriver are
required to perform commissioning of the CK Mechanical Switch
Mechanism.
INFO: For CK Standard and CKRactuators, the required end
of travel action (torque or position) is determined by the
set of switches cabled to the controlling switch gear - refer
to actuator terminal plan and site field wiring.

EFactory Calibration Fixings
WARNING: Do not adjust the fixings or position of
the yellow torque indicator plates. These are factory
configured and should not be removed under any
circumstance.
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.
(40%) & max. (100%) - by moving the cam using a screwdriver
on the adjustment point.
CAUTION: To avoid introducing an offset to the set
value when adjusting the torque trip limits. Ensure
the screwdriver remains perpendicular to the switch
mechanism faceplate.
3) Tighten the Torque Cam Clutch Screw once both torque trip
limits have been set.
CAUTION: Tighten the Torque Cam Clutch Screw until the
spring washer is fully deformed under the screw head.

1) Move the actuator to the valve CLOSED position using the
handwheel.
2) Using a flat screwdriver, depress the Drive Clutch Shaft and
rotate to the “Set” position as shown on the switch mechanism
faceplate.
3) The CLS Adjustment Screw must now be rotated to engage
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 this case it is necessary to move through the limit
and approach it from the correct direction. This avoids 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 engaged correctly.
a. The feel of the Adjustment Screw will noticeably change
providing more mechanical resistance at the switching
point of the contact.
b. Use a continuity meter on the appropriate terminals –
12 & 13 for motor control and 14 & 15 for indication
feedback to check the switch is engaged.
6) Using a flat screwdriver, depress the Drive Clutch Shaft and
rotate to the “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.
CAUTION: This must be done or the limit will be lost when
the actuator is moved.

Rotate the OLS/CLS Adjustment Shaft Clockwise. Rotate the OLS/CLS Adjustment Shaft Anti-Clockwise.
Rotate the OLS/CLS Adjustment Shaft in the direction shown next to the

CK Additional Indication Drive – Basic Settings
A 5mm Allen (Hex.) key and 0.8 x 4mm flat screwdriver with at least
120mm shaft length are required to perform commissioning of the
CK Mechanical Switch Mechanism. A small torch may be required in
environments with low level lighting.
Set Torque Limits
The torque limits can be set using the same method previously
described in this manual at the beginning of the Basic Settings
section. Access to the torque setting inputs is maintained whilst the
AID module is fitted.
Set Position Limits
The position limits can still be set with the CK AID module in place.
The OLS/CLS Indicator windows and adjustment screws can be
accessed through the labelled holes in the AID chassis.
CAUTION: It is important to remove the POT drive
assembly (if fitted) from the drive gearing prior to setting
the position limits. Refer to Setting the POT section, steps
1 and 2 for instructions on adjusting this component.
1) Move the actuator to the valve CLOSED position using the
handwheel.
2) Using a flat screwdriver, depress the Drive Clutch Shaft and
rotate to the “Set” position as shown on the AID faceplate.
3) The CLS Adjustment Screw must now be rotated to engage
the closed limit switch inside the switch mechanism. The CLS
Indicator Window will show one of four possible symbols.
Please refer to Figure 2 on page 11 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 this case it is necessary to move through the limit
and approach it from the correct direction. This avoids 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. Use a continuity meter on the appropriate terminals –
12 & 13 for motor control and 14 & 15 for indication feedback
to check the switch is engaged.
6) Using a flat screwdriver, depress the Drive Clutch Shaft and
rotate to the “Run” position as shown on the AID 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.
CAUTION: This must be done or the limit will be lost
when the actuator is moved.
