Interface Feedback
The Centronik display interface includes various features that
provide feedback to the operator. This ensures that changes to
the configuration of the actuator can be confirmed and validated
during the commissioning process.
Arrow Identification
During general menu navigation, each submenu/setting will have
a set of behaviour arrows associated with it. This lets the operator
know what can be achieved on the current screen.
Solid blocks on the setting/menu indicate navigation is not
possible. The function is read only.
Arrows on the menu/setting indicate navigation is possible – both
directions. The function is in edit mode.
An inverse arrow on the left indicates you are viewing the first
menu/setting or the lowest value.
An inverse arrow on the right indicates you are viewing the last
menu/setting or the highest value.
Confirmation Feedback
Whilst modifying settings or navigating through the various
Centronik interface menus, it is important to recognise that a
change has been accepted or saved.
A small confirmation dot will be shown in the top right corner of
the display if a valid input command has been recognised by the
Centronik interface.
For each movement, the confirmation dot will only be shown
once the Open/Close selector returns to the default rest
position.

Entering Configuration mode
To access configuration mode with the local selectors, input the
following sequence:
Each command input must be completed within 1 second of
the last and the selector knob must return to its default rest
position between each input.
Entering the User Password
The password entry process involves the same basic steps as any
other setting within the Centronik configuration.
First you will be presented with the current setting value as a read
only item (see Fig. 1). This is indicated with a solid block either side
of the value.
Fig. 1 Default password shown as read only.
By default, all Centronik Control modules will be configured with
the user level password: ROTORK
Press to confirm this entry or use to enter a
different password. For instruction on changing the user password,
refer to PUB111-005.
The arrow behaviour will indicate the setting value is in edit mode
and blank spaces will also be filled (see Fig. 2).
Fig. 2 Default password shown in edit mode.
Confirm ROTORK as the password by inputting .
Once the correct password has been entered, a confirmation
message will appear to indicate the current access level (see Fig. 3).
Fig. 3 Default password entered and access level confirmed as User.
Exit to the main menu by inputting .
There is a symbol assigned to each access level for Centronik
configuration changes. This will be displayed to the left of the
position value for the duration of the session. Each confirmation
message provides a visual prompt to correlate the symbol to an
access level.
The symbol shown to the left side of the display will reference the
following permission levels:
User level permission to provide basic access to settings
for commissioning and configuration purposes.
Super User level permission to provide access to more
advanced setting features.
Service level permission to access Centork Engineer
settings.

Limits > Torque Limit Bypass [TRQ.LIM.B.P.]
Occasionally applications will require a break to open or break to
close torque that exceeds the standard torque limit. Setting the
torque limit bypass will ignore existing torque limit settings and
apply maximum torque (up to approximately 150% or rated) across
a predetermined portion of travel.
CAUTION: The valvemaker / integrator should be
consulted to confirm the valve structure and interface
components can withstand the additional torque/thrust .
Torque Limit Bypass

direction.
Press to edit, adjust shown value using and and press
to save selection. E.g. setting at 5% will bypass the torque limit
between 0% and 5%.
The [CL.BP.POSI.] value dictates the travel away from the open
position limit that the torque limit will be bypassed in the close

Test Feedback Switches
1) Confirm the torque or limit switches are functional by
monitoring feedback on the Centronik display during switch
testing.
The main power supply must be maintained during this
test procedure to ensure feedback via the Centronik
display.
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 screwdriver
to turn LS TEST (CW for open, ACW for close). Feedback that the
switch state has changed will be seen on the Centronik display
interface.
The status text (top line) will show CLOSE.LIM. or OPEN LIM. and
the status LEDs will change from yellow (mid travel) to red or
green depending on user settings.
To confirm the normally closed control switch statuses, navigate
to the following menu within the Centronik software.
The end character displays the current status of the switch.
CLS.LIMI.X. indicates the switch has been made. As the control
switches are normally closed contact form, CLS.LIMI.X. should be
the status throughout travel until the closed limit has been reached.
CLS.LIMI.0. will then be displayed.

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

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 16 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 symbol is shown on the Centronik display.
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.
This must be done or the limit will be lost when the
actuator is moved.

For CKCor CKRC actuators fitted with a Mechanical Switch
Mechanism, the required end of travel action (torque or position)
is determined by the [ACTION] setting within the Centronik
configuration. All other limit functions will not be available as they
need to be intrusively set on the mechanism.

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 Centork.
CAUTION: The actuator position limits must be configured
prior to setting the Local Position Disc.
CAUTION: The AID cover orientation can be adjusted
through 360⁰ in 90⁰ 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
