Type 8635, Remote-Positioner

2 REMOTE OPERATION

In the case of remote operation, the positioner has no position

sensor in the form of a rotary position sensor, but is connected to

an external position sensor. The 2.5 m long connection cable is

pre-assembled on the positioner.

SENSOR

DANGER!

Risk of injury from high pressure and discharge of medium.

▶Before working on the device or system, switch o the pres-

sure. Vent or drain lines.

Risk of injury from electric shock.

▶Before working on the device or system, switch o the power

supply. Secure against reactivation.

WARNING!

Risk of injury due to incorrect assembly.

▶Assembly may be carried out only by authorized specialist

personnel and using the appropriate tools.

Risk of injury due to unintentional switching on of the plant

and uncontrolled start-up.

▶Secure system against unintentional activation.

▶Following assembly, ensure a controlled restart.

CAUTION!

Risk of injury due to heavy device.

A heavy device can fall down and cause injury during transport

or assembly work.

▶Do not transport, install or remove a heavy device without the

aid of a second person.

▶Use suitable auxiliary tools.

3.1 Installing attachment kit on the

actuator

NOTE!

To install process valves with welded body, follow the

installation instructions in the operating instructions for the

process valve.

1. Assembling switch spindle

Transparent cap

Actuator

Pilot air ports

(push-in connectors with

collets or threaded bushings)

Fig. 3: Assembling switch spindle

→Unscrew the transparent cap on the actuator and the position

indicator (yellow cap) on the spindle extension (if present).

→For version with push-in connector, remove the collets (white

nozzles) from both pilot air ports (if present).

Assembling the position sensor

Type 8635, Remote-Positioner

NOTE!

Improper assembly may damage the lip seal in the guide

element.

The lip seal is pre-mounted in the guide element and must be

"locked into position" in the undercut.

▶When assembling the switch spindle, do not damage the lip

seal.

→Slide switch spindle through guide element.

→To secure the switch spindle, apply a little screw locking paint

(Loctite 290) to the thread of the switch spindle.

→Screw guide element into the actuator cover. Ensure that the

O-ring is positioned in the actuator cover.

→Tighten guide element to 5Nm.

→Tighten switch spindle using a at-tip screwdriver, maximum

torque 1Nm.

2. Install sealing rings

→Pull the form seal onto the actuator cover (smaller diameter

points upwards).

→Check that the O-rings are correctly positioned in the pilot air

ports.

When the remote sensor is being installed, the collets of

the pilot air ports must not be tted to the actuator.

→Insert slide sideways into the switch cam; in doing so,

connect the housing of the position sensor to the actuator

and align.

NOTE!

▶The potentiometer slide must be hooked into the switch

cam.

▶Align the connection pieces of the position sensor with the

pilot air ports.

→Push position sensor without turning it onto the actuator until

no gap is visible on the form seal.

Fig. 9: Attachment of the position sensor

NOTE!

Observe tightening torque when attaching the position

sensor.

If the fastening screws are tightened too tightly, the degree of

protection IP65 and IP 67 is no longer guaranteed.

▶Tighten the fastening screws to a maximum tightening

torque of 1.5 Nm.

→Attach position sensor to the actuator using the two side

fastening screws. Observe maximum tightening torque

of 1.5 Nm.

3.3 Pneumatic connection of the position

sensor

DANGER!

Risk of injury from high pressure and discharge of medium.

▶Before working on the device or system, switch o the pres-

sure. Vent or drain lines.

Assembling the position sensor

Length of the pilot air line:

The length of the pilot air line should be adjusted to the

actuator size. The dead space volume which occurs

due to the pilot air line may negatively aect the control

characteristics.

In principle, the following applies: the smaller the actuator,

the more sensitively the control system reacts to the

length of the pilot air line.

Procedure for single-actuating actuators, control function A

and B:

→Connect working port 2 of the positioner Type 8635 via a

hose to port 1.

Working port 2, see "Fig. 1".

→Fit exhaust air line or a silencer to port 31.

The applied supply pressure must be 0.5 to 1 bar greater than

the minimum control pressure specied on the control valve. This

ensures that the control behavior is not very negatively aected in

the upper stroke range due to too little pressure dierence.

During operation keep the uctuations of the supply pressure low

(max. ±10 %). If uctuations are greater, the control parameters

measured with the X.TUNE function are not optimal.

3.4 Electrical connection of the position

sensor

DANGER!

Danger due to electrical shock.

▶Switch o the power supply and secure it against reactivation.

→Feed the cable of the positioner (with at plug tted) through

the cable gland of the position sensor.

→Connect the 3-pin at plug of the positioner to the coun-

terpart of the potentiometer.

Start-up

Type 8635, Remote-Positioner

→When tightening the cable gland, note the position of the

plug-in connection. See marked area in the following "Fig. 12".

NOTE!

The cable in the housing must have a minimum length, but

must not be under tension.

Plug-in

connection must

be within the

marked area.

troller and position sensor

→Attach body casing and screw in clockwise all the way.

4 START-UP

WARNING!

Risk of injury due to incorrect operation.

▶Prior to start-up, make sure operating personnel are familiar

with the operating instructions and have understood them.

▶The device or system should be started up by fully trained

personnel only.

Risk of injury due to unintentional switching on of the plant

and uncontrolled start-up.

▶Secure system against unintentional activation.

▶Following assembly, ensure a controlled restart.

→Connect compressed air to the positioner.

→Connect positioner pneumatically to the position sensor.

→Switch on the operating voltage of Type 8635.

→Run the X.TUNE function.

5 REMOVAL

DANGER!

Risk of injury from high pressure and discharge of medium.

▶Before working on the device or system, switch o the pres-

sure. Vent or drain lines.

Risk of injury from electric shock.

▶Before working on the device or system, switch o the power

supply. Secure against reactivation.

▶Observe applicable accident prevention and safety regula-

tions for electrical equipment.

WARNING!

Risk of injury due to improper disassembly.

▶Removal should be performed only by trained personnel

using suitable tools.

Risk of injury from hazardous media.

▶Before loosening lines or valves, ush out hazardous media,

depressurize and drain the lines.

CAUTION!

Risk of injury due to heavy device.

A heavy device can fall down and cause injury during transport

or assembly work.

▶Do not transport, install or remove a heavy device without the

aid of a second person.

▶Use suitable auxiliary tools.

5.1 Removing the position sensor

→Disconnect the pneumatic connections.
