Basic safety instructions
General hazardous situations.
To prevent injury, ensure:
▶ In the potentially explosion-risk area the positioner Type 8696 may be used only according to the specification on the separate approval sticker. For use observe the additional instructions enclosed with the device together with safety instructions for the explosion-risk area.
▶ Devices without a separate approval sticker may not be used in a potentially explosive area.
▶ Installation and repair work may be carried out by authorized technicians only and with the appropriate tools.
▶ After an interruption in the power supply or pneumatic supply, ensure that the process is restarted in a defined or controlled manner.
▶ The device may be operated only when in perfect condition and in consideration of the operating instructions.
▶ The general rules of technology apply to application planning and operation of the device.
To prevent damage to property of the device, ensure:
▶ Do not feed any aggressive or flammable media into the pilot air port.
▶ Do not feed any liquids into the pilot air port.
▶ When unscrewing and screwing in the body casing or the transparent cap, do not hold the actuator of the process valve but the connection housing of Type 8696.
▶ Do not put any loads on the housing (e.g. by placing objects on it or standing on it).
▶ Do not make any external modifications to the device housings.
NOTE!
Electrostatic sensitive components / modules.
The device contains electronic components which react sensitively to electrostatic discharge (ESD). Contact with electrostatically charged persons or objects is hazardous to these components. In the worst case scenario, they will be destroyed immediately or will fail after start-up.
▶ Observe the requirements in accordance with EN 61340-5-1 to minimise or avoid the possibility of damage caused by sudden electrostatic discharge.
▶ Also ensure that you do not touch electronic components when the power supply voltage is present.

Valve body
Process valve
Fig. 1: Structure 1
Positioner Type 8696 is an electropneumatic position controller for pneumatically actuated control valves with single-acting actuators.
Together with the pneumatic actuator, the positioner forms a functional unit.
The control valve systems can be used for a wide range of control tasks in fluid technology and, depending on the application conditions, different process valves from the Bürkert range can be combined with the positioner. Angle seat valves, straight seat valves or diaphragm valves of the Type 2300, 2301 or 2103 with an actuator size of 50 mm are suitable.

Technical data
“In rest position” means that the pilot valves of the positioner Type 8696 are isolated or not actuated.
If the ambient air is humid, a hose can be connected between pilot air outlet 2 of the positioner and the unconnected pilot air port of the third-party device for control function A or control function B. As a result, the spring chamber of the third-party device is supplied with dry air from the vent duct of the positioner.

Installation
7.2
Installation of the positioner on process valves of series 2103 and 23xx
NOTE!
When mounting on process valves with a welded body, follow the installation instructions in the operating instructions for the process valve.
When the positioner is being installed, the collets of the pilot air ports must not be fitted to the actuator.
NOTE!
Damaged printed circuit board or malfunction.
▶ Ensure that the puck is situated flat on the guide rail.
→ Align the puck and the positioner until
1. the puck can be inserted into the guide rail of the positioner (see
2. the connection pieces of the positioner can be inserted
into the pilot air ports of the actuator (see also “Fig. 7” ).
Connection pieces
Guide rail
→ Push the positioner, without turning it, onto the actuator until no gap is visible on the form seal.
NOTE!
Too high torque when screwing in the fastening screw does not ensure protection class IP65 / IP67.
▶ The fastening screws may be tightened to a maximum torque of 1.5 Nm only.
→ Attach the positioner to the actuator using the two side fastening screws. In doing so, tighten the screws only hand-tight
(max. torque: 1.5 Nm).

Pneumatic installation
8 PNEUMATIC INSTALLATION
DANGER!
Risk of injury from high pressure in the equipment/device.
▶ Before working on equipment or device, switch off the pressure and deaerate/drain lines.
Procedure:
→ Connect the control medium to the pilot air port (1)
(3 – 7 bar; instrument air, free of oil, water and dust).
→ Attach the exhaust airline or a silencer to the exhaust air port
(3)
(see “Fig. 8: Pneumatic connection” ).
Keep the adjacent supply pressure always at least 0.5 –
1 bar above the pressure which is required to move the actuator to its end position. This ensures that the control behavior is not extremely negatively affected in the upper stroke range on account of too little pressure difference.
During operation keep the fluctuations of the pressure supply as low as possible (max. ±10 %). If fluctuations are greater, the control parameters measured with the X.TUNE
function are not optimum.
Important information for the problem-free functioning of the device:
▶ The installation must not cause back pressure to build up.
▶ Select a hose for the connection with an adequate cross-section.
▶ The exhaust air line must be designed in such a way that no water or other liquid can get into the device through the exhaust air port.

10.1 Safety instructions
WARNING!
Risk of injury from improper operation.
Improper operation may result in injuries as well as damage to the device and the area around it.
▶ Before start-up, ensure that the operating personnel are familiar with and completely understand the contents of the operating instructions.
▶ Observe the safety instructions and intended use.
▶ Only adequately trained personnel may operate the equip ment/the device.
10.2 Automatic adjustment X.TUNE
To adjust the positioner to local conditions, the X.TUNE
function must be run following installation.
WARNING!
Danger due to the valve position changing when the X.TUNE
function is running.
When the X.TUNE
is running under operating pressure, there is an acute risk of injury.
▶ Never run X.TUNE
while a process is running.
▶ Take appropriate measures to prevent the equipment from being accidentally actuated.
Type 8696
Start-up
NOTE!
Avoid maladjustment of the controller due to an incorrect pilot pressure or applied operating medium pressure.
▶ Run X.TUNE
whenever the pilot pressure (= pneumatic auxiliary energy) is available during subsequent operation.
• Run the X.TUNE function preferably without operating medium pressure to exclude interference caused by flow forces.
To run X.TUNE
, the positioner must be in the AUTOMATIC operating status (DIP switch 4 = OFF).
NOTE!
Breakage of the pneumatic connection pieces due to rotational impact.
