THE ROTORK IQT RANGE – THE FIRST 1/4TURN VALVE ACTUATOR THAT YOU CAN COMMISSION AND INTERROGATE WITHOUT REMOVING ELECTRICAL COVERS.
Using the supplied infra-red Setting Tool to access the actuator set up procedures, “point and shoot” setting of torque levels, position limits and all other control and indication functions can be made safely, quickly and conveniently, even in hazardous locations. The IQT allows commissioning and adjustment to be carried out with the main power supply to the actuator switched on or off.
Standard diagnostics access information about the control system, valve and actuator status in the form of display icons and help screens.
Instantaneous valve torque and position can be monitored on the actuator with a single key press of the Setting Tool.
The on board Datalogger captures operational and valve torque data enabling informed maintenance choices to be made. IQ Insight software for PC allows the Datalogger to be interrogated, as well as the complete actuator set up to be configured and recorded.
The actuator containing the Setting Tool will be identified with a yellow label on the terminal cover.

This manual is produced to enable a competent user to install, operate, adjust and inspect Rotork IQT range valve actuators.
The electrical installation, maintenance and use of these actuators should be carried out in accordance with the National Legislation and Statutory Provisions relating to the safe use of this equipment, applicable to the site of installation.
For the UK: Electricity at Work Regulations 1989 and the guidance given in the applicable edition of the “IEE Wiring Regulations’’ should be applied. Also the user should be fully aware of his duties under the Health and Safety Act 1974.
For the USA: NFPA70, National Electrical Code ® is applicable.
The mechanical installation should be carried out as outlined in the manual and also in accordance with relevant standards such as British Standard Codes of Practice. If the actuator has nameplates indicating that it is suitable for installation in Hazardous Gas Areas then the actuator is suitable for use in Zone 1 and Zone 2 (or Div 1 and Div 2) explosive atmospheres only. It should
not be installed in atmospheres where gases are present with an ignition temperature less than 135°C, unless suitability for lower ignition temperatures has been indicated on the actuator nameplate.
Any test instruments applied to the actuator should be of equivalent certification. The electrical installation, maintenance and the use of the actuator should be carried out in accordance with the code of practice relevant for that particular Hazardous Gas Area certification.
No inspection or repair should be undertaken unless it conforms to the specific Hazardous Gas Area certification requirements. Under no circumstances should any modification or alteration be carried out on the actuator as this could invalidate the conditions under which its certification was granted.
Access to live electrical conductors is forbidden in the hazardous area unless this is done under a special permit to work, otherwise all power should be isolated and the actuator moved to a non-hazardous area for repair or attention.
Only persons competent by virtue of their training or experience should be allowed to install, maintain and repair Rotork actuators. Work undertaken must be carried out in accordance with instructions in the manual. The user and those persons working on this equipment should be familiar with their responsibilities under any statutory provisions relating to the Health and Safety of their workplace.
Thermostat Bypass
If the actuator is configured to bypass the thermostat, when using the ESD function, the hazardous area certification will be invalidated.
Control and Indication
Where the actuator build allows remote control and indication supplies higher than 150V a.c. but below 300V a.c. (refer to actuator wiring diagram) the remote control and indication supplies must be derived from a supply which is designated as installation category (overvoltage category) ll as defined in BSEN 61010 (Safety Requirements For Electrical Equipment for measurement, control and laboratory use).
Enclosure Materials
IQT actuators are manufactured from aluminium alloy with stainless steel fasteners.
The user must ensure that the operating environment and any materials surrounding the actuator cannot lead to a reduction in the safe use of, or the protection afforded by, the actuator. Where appropriate the user must ensure the actuator is suitably protected against it’s operating environment.
Should further information and guidance relating to the safe use of the Rotork IQT range of actuators be required, it will be provided on request.
WARNING: Operating by Hand
With respect to handwheel operation of Rotork electric actuators, see warning on p3.

Health and Safety
1
If your actuator cannot be installed immediately store it in a dry place until you are ready to connect incoming cables.
If the actuator has to be installed but cannot be cabled it is recommended that the plastic transit cable entry plugs are replaced with metal plugs which are sealed with PTFE tape.
The Rotork double-sealed construction will preserve internal electrical components perfectly if left undisturbed.
It is not necessary to remove any electrical compartment covers in order to commission the IQT actuator.
Rotork cannot accept responsibility for deterioration caused on-site once the covers are removed.
Every Rotork actuator has been fully tested before leaving the factory to give years of trouble free operation, providing it is correctly commissioned, installed and sealed.
3.1 Operating by Hand
WARNING
With respect to handwheel operation of Rotork electric actuators, under no circumstances should any additional lever device such as a wheel-key or wrench be applied to the handwheel in order to develop more force when closing or opening the valve as this may cause damage to the valve and/or actuator or may cause the valve to become stuck in the seated/backseated position.
Fig. 3
To engage handwheel drive, turn the Hand/Auto lever clockwise whilst turning the handwheel, see Fig 3. The lever can now be released upon which it will return to its original position. The handwheel will remain engaged until the actuator is operated electrically when it will automatically disengage and return to motor drive. If required the Hand/Auto lever can be locked in either position using a padlock with a
6.5mm hasp.
3.2 Operating Electrically
Check that power supply voltage agrees with that stamped on the actuator nameplate. Switch on power supply. It is not necessary to check phase rotation.
Do not operate the actuator electrically without first checking, using the infra-red Setting Tool, that at least the Primary Settings have been made
(refer to Section 8
page 15).
Selecting Local/Stop/Remote Operation
The red selector enables either Local or Remote control, lockable in each position using a padlock with a 6.5mm hasp.
When the selector is locked in the Local or Remote positions the Stop facility is still available. The selector can also be locked in the Stop position to prevent electrical operation by Local or Remote control.
Fig. 3.1
Local Control
With the red selector positioned at Local (anti-clockwise) the adjacent black knob can be turned to select Open or Close. To Stop, turn red knob clockwise.
Remote Control
Rotate the red selector to the Remote position (clockwise), this gives remote

3.3 Display–Local Indication
Fig. 3.2 The Actuator Display
The display consists of:
1. Red – position indication lamp
2. Yellow – position indication lamp
3. Green – position indication lamp
4. Liquid crystal display screen (LCD)
5. Infra-red sensors
6. Infra-red signal confirmation indicator (Red)
The liquid crystal display screen has 2 modes of position indication:
1. Valve position – power on
2. Valve position – power off
On power up the actuator’s liquid crystal display screen is back-lit with a “soft amber” light and one of the indicator lamps will be on, dependent on position. The display screen will show percentage open or an end of travel symbol. (See Figs 3.3, 3.4 and
3.5)
As standard, red lamp signifies valve open, yellow intermediate, and green lamp signifies valve closed. Open and closed colour functions can be reversed on request.

3.4 Display–Alarm Indication
The IQT display incorporates valve, control system, actuator and battery alarm indication in the form of four display icons. Located in the top portion of the display, each icon represents certain alarm conditions. Standard help screens are also available to assist in determining the actuator operational and alarm status (refer to Help Screens
page 64).
Valve Alarm
Fig. 3.6
The valve alarm icon, Fig 3.6, is displayed when a valve problem causes the actuator to “trip-off’’ due to the configured torque value being developed (refer to [tC]/[tO] pages 20/21).The possible causes are:
Valve tight or obstructed in mid travel.
• Valve stuck or jammed
• Valve process conditions changed (increase in pressure, flow etc.)
Once the actuator has tripped off on torque, electrical operation in the same direction is inhibited. The icon will remain displayed until movement in the opposite direction takes place.
The valve alarm icon will not be displayed when stopping at end of travel for valves configured to torque seat or torque back seat at end of travel (refer to [C2]/[C3] pages 18/19).
Tr y handwheel operation of the valve to ‘‘feel’’ for stiffness (refer to page 3).
Control Alarm
Fig. 3.7
The control system alarm icon, Fig 3.7, is displayed when the remote control system maintains an active ESD or interlock signal (the ESD, interlock function or conditional control having been enabled.)
Local and Remote operation will be inhibited while an active ESD or interlock signal is present (refer to [A1]
ESD Action page 30, [A8] External Interlocks page 32 and Conditional Control [A9] page 32.)
Investigate the operational conditions of the actuator remote control system.
5
Actuator Alarm
Fig. 3.8
The actuator alarm icon, Fig. 3.8, is displayed when an active actuator alarm is present.
Electrical operation will be inhibited while an alarm is present. The possible causes are:
• Transformer thermostat tripped
• Battery low on power up*
• Power supply fault
*see Battery Alarm
(To identify the specific cause of the alarm refer to Help Screens).
Battery Alarm
Fig. 3.9
The battery alarm icon, Fig. 3.9, is displayed when the actuator detects its battery as being low, discharged or missing.
If, on power up, the actuator detects a discharged battery and actuator power loss inhibit feature [OS] is enabled (refer to page 58), both battery and actuator alarm icons (Fig.3.8 and 3.9) will be displayed. Electrical operation will be inhibited.
When the battery alarm icon is displayed, the battery should be replaced immediately (refer to page 62).
The actuator checks the battery status at approximately 10 minute intervals. After replacing a battery the alarm icon will continue to be displayed until the next check indicates the battery is healthy. This may take up to 10 minutes.

4.1 Bases F05 to F07 and FA05 to FA07
The base adaptor must be removed to give access to the drive bush. Remove the four capscrews and base adaptor as shown in figure 4.
Fig. 4
Clear access to the drive bush is now available as shown in figure 4. Using the a 3mm allen key, unscrew the two capscrews retaining the drive bush and remove the drive bush from the actuator.
Fig. 4.1
4.2 Bases F10 to F14 and FA10 to FA14
Removal of the drive bush does not require the removal of the actuator base. Using a 3mm allen key, unscrew the two capscrews retaining the drive bush.
Capscrews can be used to remove the drive bush by screwing into the drive bush as shown in figure 4.2.
Fig. 4.2
The range of IQT drive bushes is shown in figure 4.3. Please refer to publication E110E for maximum stem acceptance details.
Fig. 4.3
4.3 Machining the Drive Bush
Once removed, the drive bush can be machined to suit the valve stem. Ensure machined position allows correct orientation of actuator-to valve flange and correct direction to close the valve.
4.4 Fitting the Drive Bush
Note: The drive bush can be fitted in two possible positions, 180º apart. Fit the drive bush into the centre column ensuring that the stem orientation, actuator position and direction of operation are correct for valve operation. Secure the drive bush with the capscrews. For F05, FA05, F07 and FA07 bases, refit the base adaptor and secure with the four capscrews.

5.1 IQT Actuators
The IQT range of actuators are suitable for part turn applications requiring up to 60 starts per hour.
5.2 IQTM Actuators
The IQTM range of actuators are suitable for modulating control duty of up to 1200 starts per hour in accordance with IEC 34-1 to S4 50%. Commissioning of IQTM range actuators is identical to the standard IQT (refer to Sections 7, 8 and 9).
5.3 IQTF Actuators
The IQTF range of actuators are suitable for part-turn and multi-turn, non-thrust applications requiring low speed and low operating turns. Commissioning of IQTF range actuators is similar to the standard IQT (refer to Sections 7, 8 and 9).
5.4 Lifting the Actuator
(Refer to Weights and Measures page 71 for actuator weight.)
Ensure the valve is secure before fitting the actuator, as the combination may be top heavy and therefore unstable.
If it is necessary to lift the actuator using mechanical lifting equipment certified slings should be attached as indicated in Figure 5. At all times trained and experienced personnel should ensure safe lifting, particularly when mounting actuators.
A suitable mounting flange conforming to ISO 5210 or USA Standard MSS SP101 must be fitted to the valve. Actuator to valve fixing must conform to; Material Specification ISO Class 8.8, yield strength 628 N/sq mm.
WARNING:
Do not lift the actuator and valve combination via the actuator. Always lift the valve/actuator assembly via the valve.
Fig. 5
WARNING:
The actuator should be fully supported until full valve stem engagement is achieved and the actuator is secured to the valve flange.
Fig. 5.1
5.5 Securing Actuator to Valve
Before engagement ensure that the actuator and valve are in the same position (i.e. closed) and the drive bush­machining matches the stem position. Actuator position can be determined using the display (refer to section 3.3 page 4) and if necessary can be moved using the handwheel (refer to section
3.1 page 3). It may be necessary to adjust the stop bolts to enable sufficient travel. Refer to section 5.6 page 9.
8
Mounting the Actuator
5
Secure actuator to valve with four fixing bolts. Check that the cast groove in actuator base is not obstructed see Fig
5.1. Its purpose is to protect the actuator in the event of a product leak from the valve stem/gland packing. Check base fixing bolts are tight.
5.6 Stop Bolts
It is recommended that stop bolt adjustment be carried out by the valvemaker/supplier before the valve is fitted into pipework. Once installed, the valve maker/supplier should be consulted before stop bolt re­adjustment is carried out. Stop bolts can be wired to prevent tampering. After setting or adjustment of stop bolts the actuator limits must be reset, refer to Limits LC, LO page 22.
The IQT stop bolts are located below the terminal compartment. Stop bolt adjustment allows +/- 5º variation of travel at each end position. Screwing bolts in reduces movement, out increases movement. For clockwise closing valves the right hand bolt is the closed stop as shown with spanner in fig 5.2. The left is the open stop. Stop bolts are factory set to give a nominal 90º travel.
Fig. 5.2
Stop Bolt sizes.
IQT 125 to 500: M12 bolt requiring 19mm AF spanner.
IQT1000 & 2000: M20 bolt requiring 30mm AF spanner.
Adjustment for non seating valves types
For closed and open stop position adjustment:
Undo stop bolt lock-nut. Move actuator and valve to the required stopping position (it may be necessary to unscrew stop bolt to allow more travel). Screw stop bolt in until a stop is felt. Tighten stop bolt lock nut.
Adjustment for seating valves types
For closed and open stop position adjustment:
Undo stop bolt lock-nut. Move actuator and valve to the required seating position of the valve (it may be necessary to unscrew stop bolt to allow more travel). Screw stop bolt in until a stop is felt and then back off by 3 turns. Tighten stop bolt lock-nut.
Reset actuator limits
Refer to Limits LC, LO page 22.
9
Ensure all power supplies are isolated before removing actuator covers.
Check that the supply voltage agrees with that stamped on actuator nameplate.
A switch or circuit breaker must be included in the wiring installation of the actuator. The switch or circuit breaker shall be mounted as close to the actuator as possible and shall be marked to indicate that it is the disconnecting device for that particular actuator. The actuator must be protected with overcurrent protection devices rated in accordance with Rotork publication No. E135E Electric motor performance data for IQT range actuators.
WARNING: Actuators for use on phase to
phase voltages greater than 600V a.c.must not be used on supply systems such as floating, or earth-phase systems, where phase to earth voltages in excess of 600V a.c. could exist.
6.1 Earth/Ground Connections
A lug with a 6mm diameter hole is cast adjacent to the conduit entries for attachment of an external protective earthing strap by a nut and bolt. An internal earth terminal is also provided, however it must not be used alone as the protective Earth Connection.
6.2 Removing Terminal Cover
Using a 6mm Allen key loosen the four captive screws evenly. Do not attempt to lever off the cover with a screwdriver as this will damage the “O” ring seal and may damage the flamepath on a certified unit.
Actuators containing a Setting Tool fitted to the inside of the terminal compartment cover are identified with a self-adhesive yellow label on the outside of the terminal compartment cover.
The wiring code card fixed in the cover is particular to each actuator and must not be interchanged with any other actuator. If in doubt check the serial number on the code card with that of the actuator.
Fig. 6
A plastic bag in the terminal compartment contains: Terminal screws and washers, spare cover “O” ring seal,wiring diagram and instruction book.
6.3 Cable Entry
Only appropriate certified Explosion­Proof entry reducers, glands or conduit may be used in hazardous locations.
Remove red plastic transit plugs. Make cable entries appropriate to the cable type and size. Ensure that threaded adaptors, cable glands or conduit are tight and fully waterproof. Seal unused cable entries with a steel or brass threaded plug. In hazardous areas an appropriately certified threaded blanking plug must be used.
6.4 Connecting to Terminals
On EExde enclosure units connections to the power and control terminals must be made using AMP type 160292 ring tabs for power and earth terminals and AMP type 34148 ring tabs for the control terminals.
Refer to the wiring diagram inside the terminal cover to identify functions of terminals. Check that supply voltage is the same as that marked on the actuator nameplate.
Remove power terminal screen.
Begin by connecting these cables and replace screen.
When all connections are made ensure wiring diagram is replaced in the terminal compartment.
6.5 Replacing Terminal Cover
Ensure cover “O” ring seal and spigot joint are in good condition and lightly greased before re-fitting cover.

7.1 The Setting Procedure
The Rotork IQ range of actuators is the first that enables commissioning to be carried out without removing covers.
Setting torque, limit and other functions is achieved by using the Infra­Red Setting Tool. The Setting Tool is certified Intrinsically Safe to allow commissioning in hazardous areas.
All the commissioning functions are stored in non-volatile memory in the actuator. The Setting Tool enables the user to view all the functions in turn via the actuator display window. As each function is viewed its setting can be checked and, if required, changed within the bounds of that function.
Commissioning may be carried out with main power switched on or off. Refer to page 15 for Power Off Setting.
The setting procedure is divided into two stages:
1. Primary Functions
Settings for end of travel limit actions, torque values, limit positions etc.
2. Secondary Functions
Settings covering the control, indication and optional equipment functions.
All IQT actuator functions are configured before dispatch to Rotork standard default settings unless alternatives have been specified with the order. Should difficulty be encountered during commissioning the default settings can be reinstated, returning the actuator configuration to its original manufactured state. Site commissioning can then begin again
(refer to Section 9.17).
The default function should be used with caution as settings selected after manufacture may be essential for the safe operation of the valve and/or plant.

The actuator’s Primary Function settings affect the correct operation of the valve by the actuator. If the actuator has been supplied with the valve, the valve maker or supplier may have already made these settings.
ELECTRICAL OPERATION MUST NOT TAKE PLACE UNTIL THE PRIMARY SETTINGS HAVE BEEN MADE AND CHECKED.
This instruction assumes setting mode has been entered (refer to section 7.4 page 13).
Viewing the Primary Function Settings
With the actuator mounted on the valve, the power supply on and Local or Stop control selected, point the Setting Tool at the actuator indicator window from a distance of no more than
0.75m. By pressing the Q key and, when appropriate, the Okey, it is possible to move through the procedure, displaying the various functions and their settings as shown in Fig. 8.1 (refer to page 16).The right­hand side of Fig.8.1 explains the function of each LCD display.
Power Off Setting
IQT allows settings to be viewed and set without main power. To enable this function, engage handwheel drive and rotate until the output drive moves (refer to page 3). The Setting Tool can now be used. As long as a Setting Tool key press takes place within the 30 seconds timeout period, Power Off Setting will remain enabled. If no infra­red Setting Tool communication takes place the display will return to indicating position. The actuator must then be operated by handwheel to re-enable Power Off Setting.
Settings and operation must be verified by electric operation and function test of the actuator to ensure correct operation.
