Note: For angle retransmit versions, refer to section 6.1

2.1.1 Move actuator vane to mid travel position, with its output square as shown in Figure 1. This is advisable to prevent

subsequent error in orientating positioner coupling. (This is not necessary with spring return actuators as there can be no

confusion with square orientation).

2.1.2 Remove positioner cover and undo the two M4 screws retaining the red angle scale plate and remove coupling as

shown in Figure 2.

2.1.3 Bolt the positioner body to the actuator in the orientation shown in Figure 1 taking care that the two O'rings are in

place to seal the ports to the actuator (place a small amount of grease onto the O'rings to keep them in place) and that the

actuator shaft is centred in the body.

2.1.4 Observe the direction that the cam moves with a rising signal and, if correct, place the coupling on the actuator

square with one hand whilst pulling back the mechanism with the other (refer to Figure 2). If the direction is not as required

then refer to section 4.1. If the actuator has been correctly positioned near mid-stroke, the cam follower will contact the

cam at approximately half way. Ensure that the coupling is pushed fully onto the actuator square and tighten the central

fixing screw which will have the effect of centralising the cam follower on cam. Refit the angle scale plate.

2.2 Mounting of Discrete Positioner.

The design and manufacture of the mount kit between the positoner and actuator is outside the scope of this document. It

is essential that the shaft of the actuator is well aligned with the positioner shaft and that the two are coupled together with

a minimum of backlash as this will reduce the performance of the positioner/actuator combination.

It is essential that the 90 degree travel of the actuator moves the positioner coupling through the correct 90 degrees of

travel. This can be achieved by either observing the position of the indicator on the lid or the position of the cam or internal

indicator with the lid removed.

2. INSTALLATION.

Positioners can be supplied direct-mounted, or ready to be direct-mounted, onto Kinetrol rotary actuators, or in stand-

alone (discrete) form for fitting via a mount kit to any 90 degree rotary or linear actuator. If the positioner is supplied

ready mounted on an actuator, sections 2.1 & 2.2 can be bypassed. Positioner-type Kinetrol actuators (ready for direct

mount of positioners) are available in models 050 to 140 inclusive.

retransmit)

2.3.1 Air Supply

Connect main air supply (pressure between 3.5 and 7 bar or 50 and 100psi) to the supply port indicated in figure 3. Also

connect signal air supply (pressure between 0.2 bar and 1 bar or 3 psi and 15 psi) to the inlet of the diaphragm housing.

It is important that the air is clean, dry and oil free. Quality class 6.4.4 (taken from ISO standard 8573.2001) is adequate.

This implies 5 micron max. Particle size, 3 deg. C dew point max. and 5mg per cubic metre max. oil content.

2.3.2 Angle Retransmit Option Supply.

The optional angle retransmit circuit is loop powered, requiring 8 to 30 volts to drive the 4-20mA current through it. The

current which passes is linearly in proportion to the shaft angle.

The cable entry has the option of a cable gland fitting or 4-way DIN plug. With the cable gland entry the wires are directly

connected to the internal Connector Block. An internal earth connection is provided if required. If the DIN plug option is

fitted then the internal connections have already been made as shown in Figure 3. An external earth connection is also

provided if this is required.

2.3.3 External Actuator Ports.

For positioners not fitted directly onto Kinetrol Positioner type Actuators, two external ports are provided for connecting

the positioner outlets to the actuator. The size of the ports is dependant on the positioner ordering code. These ports can

also be used for fitting pressure gauges if desired.

Title: Installation & Maintenance – AP Pneumatic Positioner

The AP Positioner works using the principal of a 'force balance' spool system with mechanical cam feedback. The air

input signal (normally 3-15psi) is applied to a diaphragm which produces a force on the force balance lever which is

proportional to the signal pressure. The resulting torque on the lever is balanced by the force produced from the

feedback spring which is also joined to the lever.

A proportional flow spool valve is the third element attached to the lever. This is positioned at its central closed position

when the lever is at the mid-stroke position which occurs when the actuator is at the desired angle. Several different

versions of this valve are available with different flow capacities designed to give optimum performance when fitted to

the range of Kinetrol actuators.

The feedback cam is retained by a coupling which, in the case of a Kinetrol direct mounted positioner, is held onto the

vane square by a collet. For discrete versions, the coupling is retained in bearings and connected by either a male

square or 'Namur' style connector.

The cam provides positional feedback via a unique four bar linkage which ensures a linear movement of the cam

follower whether the cam is set for clockwise or anticlockwise movement for a rising signal. The lower part of the

linkage is attached to the other end of the feedback spring which stretches the spring as the cam is rotated to produce

the feedback force mentioned earlier. The standard cam produces a linear characteristic, but alternative profiles are

available.

The common adjustments are split into zero and range. Both are achieved without the need for special tools and the

actual adjustments are made using finger pressure only.

Air passages in the main body are provided with the capability of many options with a minimum of changes. External

ports are provided on all models to allow for external connection to the actuator or for the fitting of pressure gauges if

desired. Three main air flow options are available (as detailed in the AP literature). The two lower flow rate options (AP

& MP) are affected by change of valve size and tapping size in the body. The largest flow rate option (HP) not only has

a larger valve but also a different port plate with 3/8 tapping and external combination silencer/snubbers.

The mounting options are accommodated by three different channel plate designs. The channel plate is the plate fitted

to the base of the unit. The smallest is dedicated to direct mounting on an 050 Actuator. The second is used for direct

mounting on Actuators 070 to 140. The third is used for discrete models having a Namur mounting hole pattern.

An optional angle retransmit can be fitted within the positioner body and additional options of I/P controller and limit

switch box can also be fitted allowing a wide range of switch options to be specified.

Title: Installation & Maintenance – AP Pneumatic Positioner

4.1.1 Move the actuator to approximately mid-position to avoid problems in correct orientation later. This is obviously not

possible or necessary with spring return models because the position of the vane will be known. Reduce both main supply

and signal pressures to zero.

4.1.2 Remove positioner cover and undo the two M4 screws retaining the red angle scale plate and remove, as shown in

Figure 5. Loosen the central coupling screw sufficiently to draw the coupling off the actuator square.

4.1.3 Pull the two halves of the coupling apart sufficiently to allow the cam to be withdrawn from its location peg as shown

in Figure 6. Flip the cam over and push it back into the slot between the two coupling halves and locate it back on the peg.

4.1.4 If when the coupling was removed, the collet was left behind on the actuator square, remove the collet from the

square and push it into the lower half of the coupling ensuring that it locates in the semicircular 'pip'. Tighten the clamping

screw by two turns before placing it back on the actuator square such that the cam follower is approximately half way up

the rise of the cam and tighten the clamping screw. Replace the angle scale plate.

4.1.5 Undo the changeover block central screw and rotate it by a quarter turn and replace and tighten screw. For your

convenience, the changeover block is marked 'A' and 'C' which refers to 'anticlockwise' and 'clockwise' respectively.

Ensure the required letter is placed opposite the arrow marked on the top of the valve block.

4. SETTINGS AND ADJUSTMENTS.

The positioner will have been factory set to the requirements given in the ordering code ( i.e. the direction of rotation for

a rising pressure signal and the range and zero settings). However, if these settings need to be changed, the following

section describes the procedure for achieving this.

4.1 Change of Direction for Rising Signal (direct mounting units only).

4.2 Zero and Range Adjustment (refer to Figure 4).

4.2.1 Move the actuator/positioner to the zero end of the stroke (i.e. when the cam follower is at the beginning of its rise).

This can be most easily achieved by pressurising the main air supply without any signal air pressure (spring return models

will already be at this position. Exhaust the supply air and move the internal indicator to indicate just below zero on the

angle scale.

4.2.2 Set the coarse zero by slackening the coupling screw by approximately half of a turn until the top part of the coupling

can be rotated by hand and rotate until the cam follower just starts to rise up the cam profile. Retighten the screw.

4.2.3 Turn on the main air supply and carefully increase the signal supply pressure to 3psi (0.2Bar). Slacken the fine zero

adjustment clamp screw and rotate zero adjuster using thumb pressure so that the actuator moves to indicate zero on the

internal indicator. Tighten clamp screw.

4.2.4 Increase the signal pressure to 15psi (1 Bar). Slacken the range adjuster clamp screw and rotate the adjuster knob

between thumb and forefinger until the actuator moves to the desired end stroke position (normally 90 degrees) as

indicated on the internal indicator. Re-tighten the clamp screw.

4.2.5 Reduce the signal air pressure again to 3 psi and check that the zero position has not changed.

4.3 Speed Control.

Maximum actuator speed can be regulated by the two following methods:

a.) Changing the valve spool/liner size. The valve size is normally specified at the point of ordering by the letters 'AP', 'MP'

or 'HP'. This method, however, not only effects the actuator speed but also effects the 'gain' and therefore control stability

of the unit and care must be taken not to specify a too high flow valve for a given size of actuator. Kinetrol Ltd has

recommendations (shown in the AP literature) for each size of the actuator

or

b.) adjustment of the built in flow restrictors (shown in Figure 4) is achieved using a screwdriver. There are two restrictors,

one for each direction of travel. Clockwise rotation, this will reduce the actuator speed. 'AP' and 'MP' size units with 1/8 or

1/4 ports are controlled in this way but 'HP' size units having 3/8 ports are fitted with external silencer/restrictors which are

adjusted using an allen key fitted down the centre of the adjuster.

4.4 Change of Direction for Rising Signal (discrete units).

4.4.1 Move actuator as in Section 4.1.1.

4.4.2 Remove positioner cover and undo the three M4 screws retaining the red retransmit plate, as shown in Figure 7.

Loosen the central coupling screw sufficiently to pull the coupling complete with the retransmit assembly off the actuator

connection.

4.4.3 Remove the internal indicator from the coupling and withdraw the coupling from the retransmit plate.

4.4.4 Pull the two halves of the coupling apart sufficiently to allow the cam to be withdrawn from its location peg. Flip the

cam over and push it back into the slot between the two coupling halves and locate it back on the peg.

4.4.5 Refit the coupling to the retransmit plate and slide the internal indicator over the top of the coupling.

4.4.6 If when the coupling was removed, the collet was left behind on the actuator connection, remove the collet from the

connection and push it into the lower half of the coupling ensuring that it locates in the semicircular 'pip' and tighten the

clamping screw by two turns. Place the coupling and retransmit plate back on the actuator connection such that the cam

follower is approximately half way up the rise of the cam and pull back the spring lever with the other hand and tighten the

coupling clamping screw. Re-tighten the retransmit plate retaining screws.

4.4.7 The internal changeover block is not effective with a discrete positioner. The changeover of the airflow path is

achieved by swapping over the external connections. It may also be preferred to turn the positioner through 180 degrees

to simplify the external pipe runs.

4.4.8 The adjustment of zero and range is completed as in section 4.2.

TABLE 1. Troubleshooting Guide

Failure to move when signal air and mains air is applied

- Check mains air pressure is sufficient to produce enough torque from actuator

- Check signal pressure using pressure gauge in gauge port or check that the force balance lever is being pushed by

the input diaphragm with the lid removed

- Has the coupling been positioned at the correct angular position on the actuator?

- Has the changeover block been set correctly for the direction of rotation (direct mounted units) or the external port

connections been fitted the correct way around (discrete units)?

- Is the air quality poor, causing the spool to jam? This can be checked by manually moving the spool carefully by

hand with the lid removed.

- Is the actuator or whatever it is connected to jammed? This can be checked by again moving the force balance lever

manually to check if the actuator responds (air will normally be heard hissing into the actuator when this is done).

Actuator moves too slowly upscale or down scale:

- Is the mains air pressure too low for the load being moved or the actuator too small?

- Have one or both flow adjuster screws been screwed in too far?

- Is the air contaminated causing the spool movement to become sluggish?

- Is the actuator volume too large for the spool flow rate chosen?

Lack of sensitivity:

- Is the spool sticky, caused by a contaminated air supply?

- Does the actuator exhibit poor stick slip qualities? This may be especially true if it is not Kinetrol and will normally be

seen also as a jerky movement.

Excessive Hysteresis:

- Has the inside of the positioner box become contaminated causing the force balance mechanism bearings to

become sticky?

- Is the actuator load excessive causing it to struggle to achieve position?

Overshoot/Instability:

- Is the spool valve chosen too large for the size of the actuator?

- Is the inertia loading too great for the size of actuator chosen? Refer to Kinetrol for allowable limits.

- Have the snubbers been used to slow the load down?

5. MAINTENANCE AND TROUBLESHOOTING.

The AP positioner is designed for a long life with very little maintenance required if it is supplied with clean, dry oil free air,

as recommended in section 2.3.

When the positioner lid is removed, take care not to remove all grease from the lid/coupling seal. If it does need

replenishing then ensure that a synthetic grease is used as a mineral oil grease will adversely affect this seal.

If, however, any of the parts do need replacement because of adverse conditions, then refer to Kinetrol Ltd for spare parts

together with any instructions for replacing and resetting.

The following trouble shooting guide should help in the unlikely event of a problem with the performance of the unit. If

problems persist, contact your local Kinetrol distributor or Kinetrol Ltd for further advice.

6.1.1 Move actuator vane to mid travel position, with its output square as shown in Figure 1. This is advisable to prevent

subsequent error in orientating positioner coupling. (This is not necessary with spring return actuators as there can be no

confusion with square orientation).

6.1.2 Remove positioner cover and unscrew the three M4 screws retaining the red retransmit plate, release the two wires

on the terminal block connected to the DIN plug (if fitted), as shown in Figure 7, and carefully remove coupling and

retransmit assembly as one unit.

6.1.3 Bolt the positioner body to the actuator in the orientation shown in Figure 1 taking care that the two O'rings are in

place to seal the ports to the actuator (place a small amount of grease on to the O'rings to keep them in place) and that

the actuator shaft is centred in the hole in the body.

6.1.4 Observe the direction that the cam moves with a rising signal and that the retransmit strap is fitted to the correct slot

in the lower coupling as marked (C & A for clockwise and anticlockwise respectively). If the direction is not as required

then refer to section 6.2. If correct, place the coupling and retransmit assembly on the actuator square with one hand

whilst pulling back the mechanism and two DIN plug wires with the other (refer to Figure 6). If the actuator has been

correctly positioned near mid-stroke, the cam follower will contact the cam as approximately half way.

6.1.5 Ensure that the coupling is pushed fully on to the actuator square and tighten the central fixing screw which will

have the effect of centralising the cam follower on the cam track. Retighten the three angle retransmit retaining screws

and refit the two DIN plug wires (if fitted).

6.2 Change of Direction for Rising Signal (direct mounting units only).

6.2.1 Move the actuator to approximately mid-position to avoid problems in correct orientation later. This is obviously not

possible or necessary with spring return models because the position of the vane will be known. Reduce both main

supply and signal pressures to zero.

6.2.2 Remove positioner cover and undo the three M4 screws retaining the red retransmit plate, release the two wires on

the terminal block connected to the DIN plug (if fitted), as shown in figure 7. Loosen the central coupling screw sufficiently

to carefully pull the coupling complete with the retransmit assembly off the actuator square.

6.2.3 Release the potentiometer strap from the slot in the lower coupling, as shown in figure 8, remove the internal

indicator from the coupling and withdraw the coupling from the retransmit plate.

6.2.4 Pull the two halves of the coupling apart sufficiently to allow the cam to be withdrawn from its location peg. Flip the

cam over and push it back into the slot between the two coupling halves and locate it back on the peg.

6.2.5 Refit the coupling to the retransmit plate, slide the internal indicator over the top of the coupling and refit the

potentiometer strap into one of the two marked slots of the lower coupling (marked 'A' and 'C' for anticlockwise and

clockwise movement respectively).

6.2.6 If when the coupling was removed, the collet was left behind on the actuator square, remove the collet from the

square and push it into the lower half of the coupling ensuring that it locates in the semicircular 'pip' and tighten the

clamping screw by two turns. Place the coupling and retransmit assembly back on the actuator square so that the cam

follower is approximately half way up the rise of the cam whilst holding back the two retransmit wires and pull back the

spring lever with the other hand and tighten the coupling clamping screw. Re-tighten the retransmit plate retaining screws

and refit the retransmit wires to the terminal block.

6.2.7 To ensure a rise in retransmit signal with rising input pressure signal, the top and bottom wires on the feedback

potentiometer must be reversed in the connector located on the circuit. The central wire does not change.

6.2.8 Undo the changeover block central screw and rotate it by a quarter turn and replace and tighten screw. The

changeover block is marked 'A' and 'C' which refers to 'anti-clockwise' and 'clockwise' respectively. Ensure the required

letter is placed opposite the arrow marked on the top of the valve block.

6.3 Zero and Range Adjustment (refer to Figure 7).

Setting of the mechanical zero and range for the positioner with an angle retransmit is the same as described in section

4.2. The retransmit circuit must also be set for zero and range which is described below.

6.3.1 Set the circuit zero adjustment to the central position and connect a 4-20ma electrical source via the DIN plug or

terminal block.

6.3.2 Set the positioner to zero degrees or the input pressure to 3 psi (0.2 Bar)

6.3.3 Slacken the two screws which clamp the potentiometer to the retransmit plate but do not remove. Rotate the

potentiometer slowly using finger pressure until the electrical display shows 4ma.

6.3.4 Increase the air signal pressure to 15 psi (1 Bar) to set the positioner at 90 degrees. Adjust the Span potentiometer

to read 20ma.

6.3.5 Repeat steps 6.3.2 to 6.3.4 until the desired readings are obtained at both ends of the stroke. The fine zero

potentiometer can be used to obtain a more precise reading at the zero position.

6.3.6 Tighten the two potentiometer clamp screws.

6.4 Change of Direction for Rising Signal (discrete units).

6.4.1 Move actuator as in Section 6.2.1.

6.4.2 Remove positioner cover and undo the three M4 screws retaining the red retransmit plate, release the two wires on

the terminal block connected to the DIN plug (if fitted), as shown in figure 7. Loosen the central coupling screw sufficiently

to pull the coupling complete with the retransmit assembly off the actuator connection.

6.4.3 Release the potentiometer strap from the slot in the lower coupling, as shown in Figure 8, remove the internal

indicator from the coupling and withdraw the coupling from the retransmit plate.

6.4.4 Pull the two halves of the coupling apart sufficiently to allow the cam to be withdrawn from its location peg. Flip the

cam over and push it back into the slot between the two coupling halves and locate it back on the peg.

6.4.5 Refit the coupling to the retransmit plate and slide the internal indicator over the top of the coupling and refit the

potentiometer strap into one of the two marked slots of the lower coupling (marked 'A' and 'C' for anticlockwise and

clockwise movement respectively).

6.5 Change of Angle Retransmit Direction Without Changing Positioner Direction

If a non-standard rise in retransmit signal is required without a change in positioner direction, then this can be

achieved by the following procedure.

6.5.1 Swap the top and bottom wires on the angle retransmit circuit which connect to the potentiometer.

6.5.2 Repeat the zero and range set-up procedure described in section 6.3.

6.6 Angle Retransmit for angles of less than 0º to 90º

If the positioner is fitted with a non-standard cam with a special characteristic, it may be necessary to move the

jumper (located under the angle retransmit circuit cover) to link the pins in order to achieve the correct feedback

signal range.
