1.2 Connecting to the actuator
The Rotork Bluetooth® Setting Tool Pro incorporating Bluetooth
wireless technology is shown below. It is identified by the key
symbols and a clear band between the top and bottom casings
being transparent.
The Rotork Infrared Setting Tool Pro is identified by solid yellow
keys and a yellow band between casings:
Yellow: Rotork Infrared Setting Tool Pro
Clear: Rotork Blueto oth® Setting Tool Pro
Connecting to the actuator using Bluetooth
The actuator must be powered up to connect using Bluetooth. The
default security set in the actuator for Bluetooth connection is by
initiation using an infrared command. This means that the user must
be in close proximity and in direct line of sight of the actuator.
Point the Setting Tool at the infrared sensor located at the lower
right of actuator display window within a range of 0.25 m (10 in)
and press until the key flashes blue.
The screen will change to the Main Menu screen.
Open Limit
The Setting Tool will automatically connect using
Bluetooth which takes up to 5 seconds.
Connection is indicated by a blue light on the tool and in the
actuator display window. Once connected, the tool can be used
without pointing it at the actuator display window.
Bluetooth connection will be maintained while Setting Tool key
commands are made. After a period of 6 minutes with no key
commands, Bluetooth connection will be turned off and the
Setting Tool and display blue lights will go out. To manually
disconnect Bluetooth at any time, press and together.
Connecting to the actuator using Infrared
Infrared communication is used when:
• Bluetooth communication has been disabled
(refer to 2.5).
• configuration is required without power being applied to
the actuator.
• legacy infrared only Rotork Setting Tool is used
(yellow banded tool).
The Infrared only tool has solid yellow keys and a yellow band
between casings.
Communication is by direct line of site infrared commands within
a range of 0.25 m (10 in). Keys have the same function as shown
in this manual. Each key press sends a discreet infrared command
and therefore the tool must be in range.

3/15 Close Torque
The value of torque available to close the valve can be limited
between 40% and 100% of its nameplate rated torque. If the
actuator experiences the set torque when closing between the
limits, it will stop and must then be reversed before it will move
closed again. Operational torque can be monitored using the
data log (refer to 4) and using the torque-position home screen
(refer to 2.2.2).
The default setting for closed torque limit is 40%. If a
value of torque was specified at time of order, the %
value equating to the specified torque will have been set
by Rotork.
If the actuator was delivered complete with valve, the
valvemaker may have set the closed torque limit based on
testing and/or design requirements.
In the absence of valvemaker instruction, set the minimum
value required to close the valve under process conditions.
To change,

Hardwired Control is a standard feature. The default
settings are shown above.
Hardwired Control is a standard remote control form
available on all actuators. It allows settings for hardwired
2-wire priority control and interlocks.
1/3 2-Wire Priority
Sets the action the actuator perform when a close and open
signal are applied simultaneously. Hardwired remote control
form C uses the priority action (open or closed) to set the
actuator response when 2 signals are applied. Refer to the
wiring diagram and its referenced RWS control diagram.
On applying hardwired close and open signals together, the
actuator will:
Open – The actuator will move open.
Stop (default)
–
The actuator will not move, or will stop if running.
Close – The actuator will move closed.
To change,
the selected 2-wire control mode will be indicated.
. The drop down list will close and
Conditional – Close and open interlock inputs are enabled,
interlocking is available and will be active in remote control
only. The actuator will not run under remote control unless
interlock signals are applied to the closed control and closed
interlock input or the open control and open interlock input.
Remote control is conditional on 2 signals being applied
simultaneously and therefore integrity of operation due to
spurious control signals is increased. Local control is available
without interlock inputs.
Partial Stroke – Partial stroke testing demonstrates the
operational integrity of the valve and actuator by moving them
for a set portion of stroke. A remote "partial stroke" hardwired
signal applied to the open interlock input is used to initiate a
partial stroke test. For setting the partial stroke test parameters,
refer to 2.3.2-3. When set to partial stroke, the closed interlock
is disabled. Partial stroke initiated via a network command (with
a network option fitted), does not require the interlocks to be
configured for partial stroke.
To change the settings use
list will close and the selected interlock mode will be
. The drop down
indicated.
3/3 Motor Enable
Sets the remote control maintain function when the motor
enable feature is used. When using motor enable, the maintain
line on terminal 34 becomes the permissive input.
Disabled (default) – Maintain function is controlled by applying
a signal to terminal 34.
Push to Run – Remote controls are push to run. On removal of
the remote open or close command, movement will stop.
Maintained – Remote controls are self maintained so only a
pulse is required. Removal of the remote open or close signal will
not stop operations. To stop movement, you must remove the
motor enabled signal.
2/3 Interlocks
Sets the mode for the interlock inputs, refer to wiring diagram.
External interlocks can be used to prevent operation of the
actuator until a certain process condition is met. An example is a
main and bypass valve system. The main valve is interlocked with
the bypass valve such that it cannot be opened until the bypass
valve is fully open.
Disabled (default) – The interlock inputs are disabled,
interlocking is not available.
Enabled – Close and open interlock inputs are enabled,
interlocking is available and will be active in both local and
remote control. The actuator will not run in local or remote
control unless interlock signals are applied to the closed or the
open interlock input. If only one interlock is required, for example
an interlock to prevent closed operation, the open interlock must
be linked out.

Refer to wiring diagram for options fitted.
Introduction
In addition to standard hardwired control, the actuator can have
up to two remote control options fitted. For most remote control
systems employed by end-users, only one control option is used.
For control systems using Analogue control only or where
Analogue and Network (such as Modbus) control is used,
control (Hardwired/Analogue or Analogue/ Network) can be
switched by the user using the Manual/Auto input available with
the analogue option and the settings made in Control Source.
When Analogue and Network options are fitted and Analogue
is switched to control, the Network option cannot control the
actuator but will continue to report actuator status.
The control source will be set by Rotork to the defaults
required for the option(s) fitted. Refer to Table: Control
Source Settings.
For analogue control, if both Manual (hardwired control
inputs) and Auto (analogue control) is to be used, the
control selection will require re-setting. If only analogue
control is required, the default settings for Control Source
will be correct. Refer also to 2.3.2-6.
The control source is used to:
• Control Source 1/Source 2 - Associate fitted control option(s)
to a source of control (source 1 or source 2).
• Control Selection - Set which control source (1 or 2) has
priority when Manual/Auto input is used to switch between
Analogue and Network option sources.
• Lost Signal - Determines the actuator response to a lost
analogue signal or network communication.

Partial Stroke is a standard feature. The default settings
are shown above.
Partial stroke testing is used to demonstrate the operational
integrity of the valve and actuator by moving over a set portion
of valve stroke. In addition, partial stroking may be used
to exercise infrequently operated valves to help keep them
mechanically free. Partial stroke test can only be initiated when
the actuator is at the set From Limit position.
A partial stroke test may be initiated by a remote partial stroke
signal applied to the open interlock*, a network command
(network option fitted) or using the test control on the partial
stroke page.
*Interlocks must be set to partial stroke, refer to 2.3.2-1.
Partial stroke test results (torque and pass/ failure status) are
captured by the data log.
Partial stroke operation, pass and failure can be indicated by the
