Preliminary remarks

1. Note the serial number for future reference.

2. The positioner is fitted with a powerful magnet: do

not bring close to it a watch or an instrument likely to

deviate under the inﬂuence of a magnetic ﬁeld.

Introduction

This version of the Positioner can be manufactured to

meet the requirements of each standard pertaining to:

— protection against explosion for equipment intended

to be installed in an hazardous atmosphere;

— protection against dust and against water-splash for

tight equipment;

— sometimes a combination of the two preceding

protections.

The instructions pertaining to these standards as well as

to electric characteristics of the positioner are further

explained in a supplementary Instruction sheet No ES

50004-000 E.

Caution

This equipment should not be installed, kept up or put

into operation without having read and fully understood

before-hand the instructions contained in this

instruction sheet and in the supplementary sheet

NoES50004-000E

Moreover, before initiating any operation on this

positioner the following should be read:

a) operating instructions pertaining particularly to

installation.

b) safety rules listed on the instruction plate attached to

the cover of the device in certain cases (positioners

with explosion-proof housing).

Non-compliance with these rules may bring about faulty

operation of the device, interfere with the installation or

damage it seriously. In addition, such negligence might

expose operating personnel present on the site to grave

hazards.

8013 Series Positioners with cam, mounted on

35002 Series CamﬂexII and 30000 Series Varimax

General

The positioner is an electropneumatic force-balance

device which provides an accurate means of obtaining

at any time a valve stem position corresponding to a

theoretical position envisaged for a DC input signal. In

addition, the positioner provides a convenient means of

split-ranging operation for several valves (usually two)

from a single signal emitted by a single controller. The

positioner may have either direct or reverse action on

either direct or reverse actuators.

The feedback device of this positioner is ﬁtted with one

single cam with several lobes permitting the valve to

present the following characteristics: linear, split-ranging

linear, equal percentage. The cam is directly mounted

on the end of the valve shaft (CAMFLEXII) or on the

pivot of actuator case (Varimax); thus avoiding the

drawbacks inherent in the connecting linkage.

Direct action

With direct positioner action, an increase in the output

signal produces a force on the beam moving the ﬂapper

to cover the nozzle. The increase in nozzle back pressure

increases positioner output pressure to the actuator. The

resultant actuator stem motion is transmitted to the

force-balance spring, extending the spring until the force

exerted on the beam balances the opposing force of the

coil. As these two forces equalize, nozzle back pressure

decreases. The system then is balanced and positioner

output pressure is stabilized at an amount necessary to

maintain the control valve stem in the desired position

corresponding to the input signal value.

Reverse action

With reverse positioner action, an increase in the input

signal produces a decrease in output pressure.

Changing of action

a) Reverse the positions of the coil leads on the

terminal board (see Instruction sheet No ES

50004-000 E, page 3).

b) In case of intrinsically safe circuit, replace the coil by

another one corresponding to the new action

(Instruction sheet No ES50004-000 E, page 3).

c) In case of flameproof housing device, the

positioner case must not be opened when the

device is energized.

d) Reverse the force balance spring position in regard to

the beam (see corresponding paragraph of page 5).

e) Calibrate after changing of action.

f) Consult the instruction sheet No ES50004-000 E.

split-range operation

The following instructions apply only when the

positioners are mounted according to the diagrams of

Figure 3.

Therefore, total circuit resistance of positioners installed

for split-range operation must be in accordance with the

total load requirement of the controller. The choice of the

connecting type (in series or parallel) as well as the

positioner characteristics are according to the signal and

to the impedance of the circuits.

Masoneilan supply, in case of need, the data required

for the selection of the equipment or for its modiﬁcation

in the ﬁeld.

2. Be sure that the coil and the terminal board are

correct for the input signal characteristics. Refer to

table on page 4 of the instruction sheet No ES

50004-000 E for identiﬁcation code number of these

items.

Position of the force balance spring

The position of the force balance spring (8) in regard to

the beam depends on the action of the positioner (see

Figure 5). If the positioner action is direct, the force

balance spring is located under the beam. If the

positioner action is reverse, the spring is located over

the beam. To change the spring position follow the

instructions of the paragraph further on.

Changing position of force balance

spring

To change position, remove nuts (11), hooking screw

(12) and force balance spring (8). Reverse the position

of adjusting screw (6) on the beam keeping locknut (7)

on the top side. Replace the force balance spring (8)

with hooking screw (112) in the correct square hole in

the spring lever (10). On half its threaded length, screw

(12) must be blocked with nuts (11).

Caution: The hole located at the end of the square

hooking screw should be perpendicular to the

bottom of the case.

Mounting the case (Figure 4)

Note: If the cam (155) was mounted on the CamflexII

valve shaft or the Varimax pivot, remove it before

installing the positioner.

With two screws H (152) and with the countersunk head

screw, assemble the mounting plate (171) on the

molded bracket of the positioner and on the positioner

(The molded bracket is already integral to the positioner

with the two ﬁllister-head screws). Then, secure the set

on the valve yoke with two countersunk head screws

(172). The orientation of the positioner on the valve is

indicated in Figure 4.

Cam mounting and orientation (Figures

6 and 7)

Select the proper cam lobe for the desired ﬂow control

characteristics. (See Figure 6). Place the cam (155) on

the bushing (159) in order that the identiﬁcation number

of the cam lobe should be facing away from the bushing

once the cam is assembled (See Figure 7).

CAUTION : If the cam bushing hex protrudes

through the hex hole on the front side of the cam it

means that the cam is on the wrong end of the cam

bushing.

Place the disk spring (156) on the cam screw (160).

Place cam with cam bushing on cam screw (160) (with

cam engaged against the outside diameter of the disk

spring). Place lock washer (158) on the cam screw (160)

and assemble on the shaft of Camflex II or on the

Varimax pivot. Turn the cam to line-up the original mark

of the lobe with the center of the bearing as indicated in

Figure 7.

CAUTION: Lift cam follower bearing so as to allow

the lobe to align with the follower bearing. Tighten

cap screw (160).

Pneumatic circuit

The positioner output and supply connections are

screwed 1/4”NPT. They are located on the relay and

marked with arrows. The diameter of the connecting

piping between the air ﬁlter-regulator, the positioner and

the actuator is 4x6mm (1/4” O.D.).

Supply circuit

The utilization of an air filter-regulator model 77-4 is

recommended on the supply circuit. Be sure that its

assembly position is correct. (drain-cock and dripwell

downward).

For the supply of the air filter-regulator use 1/4” O.D.

tubing (4x6mm Dia.). If air line exceeds approx. 7m.

length (23 feet), preferably utilize 3/8” O.D. tubing

(6x8mm Dia.).

the positioner are in accordance with the valve and the

actuator on which it is mounted. For CamflexII valves

these maximum pressures are indicated in the

Instruction No EF 50004 E. For Varimax valves, they are

indicated in Instruction No EN3000 E

Output circuit

The pneumatic output connection to the actuator should

be particularly tight.

Electrical circuit

See Instruction sheet No ES50004-000 E.

General

1. The Model 8013 Positioner, when factory mounted,

has been calibrated for the proper valve and

positioner actions. If for any reason the cam and

cam bushing (159) setting has been destroyed (for

example, a change of positioner action or cam lobe,

for ﬁeld installation or for maintenance, etc...) then it

is necessary to follow all steps of calibration

instructions, according to the desired actuator and

positioner actions.

2. Connect air lines to positioner and actuator. Connect

the leads of the input electric signal respecting

polarities stamped on the terminal board.

3. Check force balance spring position according to the

direction of the positioner action (see Figure 5)

4. Turn the force balance adjusting screw (6) on the

beam (41) in order that the spring should be

approximately parallel to the joint plane of the case.

(see Figure 5).

1. Proper cam mounting.

2. Proper fastening of positioner on valve yoke.

3. Correct positioning of the force balance spring (8).

4. Proper positioning of coil lead connections and

signal leads to terminal board.

5. Correct pneumatic connections.

6. Supply pressure required by valve operating

conditions and size. Refer to valve catalogs,

instructions or serial plate.

7. Proper control signal and input impedance for

utilized controller. Consider line resistance (see

table of Figure 4 of Instruction sheet No ES50004-

000 E.

8. Coil stop adjusted to allow approximately (0.8mm)

(1/32”) ﬂapper travel in front of nozzle.

9. All mechanism components fastened firmly as

required.

10. Proper nozzle size selected. Number of nozzle

stamped on body of nozzle. The table below

indicates nozzle number for each utilization case.

Pneumatic circuit

In the event of faulty operation of the positioner, where

the cause is not readily apparent, check air system as

follows:

1. Exert sufficient force on the flapper to cover the

nozzle. Valve stem should travel its full stroke.

2. If response is other than indicated in the above

steps, push cleanout plunger of metering oriﬁce,

Inspect for plugged nozzle. Check to see if metering

oriﬁce body is properly seated in the relay. If difficulty still

persists, disassemble and clean relay.

Electrical circuit

After checking pneumatic circuit, the electrical circuit

should be checked with an ohmmeter as follows:

1. Disconnect signal leads from terminal board S/A.

2. Connect ohmmeter leads to positioner terminal

board leads and check positioner circuit resistance

with nominal resistance indicated on identification

plate. Table of Figure 4 of the Instruction sheet No

ES50004-000 E shows the nominal resistance of

main circuits.

3. Disconnect coil lead from positive terminal and

connect to one of the ohmmeter leads. Connect

other ohmmeter lead to negative terminal. Force coil

resistance value should approximate value indicated

in table of Figure 4 of Instruction sheet No

ES50004-000 E.

4. If force coil resistance is approximately correct but

positioner circuit resistance is not, repair or replace

terminal board. If force coil resistance is not correct

replace force coil.

5. Remove ohmmeter lead from negative terminal and

connect it to coil stop screw. Check for short in force

coil.

Replace the coil if ohmmeter indicates a value other

than very high resistance (practically inﬁnite).
