Intended use
2 INTENDED USE
Use of the 1062 electrical position feedback that does not
comply with the instructions could present risks to people,
nearby installations and the environment.
▶ The 1062 electrical position feedback, fitted to an on/off valve,
is used to detect the status - open or closed - of this valve.
▶ The position feedback can be fitted to an actuator valve with a
diameter of 40 to 125 mm.
▶ Protect this device against electromagnetic interference, ultra-
violet rays.
▶ Protect a device installed outdoors from the effects of climatic
conditions.
▶ Use this device in compliance with the characteristics and
commissioning and use conditions specified in the contractual
documents and in the user manual.
▶ Requirements for safe and proper operation are proper trans-
port, storage and installation, as well as careful operation and
maintenance.
▶ Only use the device as intended.
2.1 Restraints
Observe any existing restraints when the device is exported.
2.2 Ex certification
Ex certification is only valid if modules and components approved by
Bürkert are used as indicated in this user manual.
The electronic modules can only be combined with the types of
pneumatic valves authorised by Bürkert; if this is not the case, Ex
certification is void.
Any modification to the system or to one of the modules or components not authorised beforehand also voids Ex certification.

Basic safety information
3 BASIC SAFETY
INFORMATION
This safety information does not take into account:
• any contingencies or occurences that may arise during assembly,
use and maintenance of the devices.
• the local safety regulations that the operator must ensure the staff
in charge of assembly and/or maintenance observe.
Risk of explosion.
When the 1062 is used in an ATEX 21 or 22 zone, make sure:
• That the cover of the electrical position feedback is always
screwed shut before operating the valve.
• That you check that the device is not subject to a flow of air and
dust that may result in an accumulation of electrostatic charges.
Otherwise, intall the device in a conductive cover.
• "The NAMUR switches on the 1062 must be powered by a voltage
source of a type certified for use in explosive atmospheres in
groups IIB/IIC and their combination must be compatible from the
instrinsic safety point of view."
Danger due to high pressure in the installation.
▶ Shut down the pneumatic power source and depressurise the
pipes before carrying out work on the device.
Risk of injury due to electrical discharge.
▶ Shut down the electrical power source of all the conductors and
isolate it before carrying out work on the system.
▶ Observe all applicable accident protection and safety regula-
tions for electrical equipment.
Various dangerous situations
To avoid injury take care:
▶ to prevent any power supply switch-on.▶ to ensure that installation and maintenance work are carried out
by qualified and skilled staff with the appropriate tools.
▶ to guarantee a set and controlled restarting of the process, after
an electrical and/or pneumatic power supply interruption.
▶ to use the device only if in perfect working order and in compli-
ance with the instructions provided in the user manual.
▶ to observe the general technical rules when locating and using
the device.
• not to use non-Ex certified versions of the 1062 electrical position
feedback in a potentially explosive atmosphere.

Various dangerous situations (cont'd)
To avoid injury take care:
• not to use outdoors a device approved by CSA.
• not to use this device in an environment incompatible with the
materials from which it is made.
• not to subject the device to mechanical loads (e.g. by placing
objects on top of it or by using it as a step).
• not to make any external or internal modifications to the device.
note
Elements / Components sensitive to electrostatic discharges
▶ This device contains electronic components sensitive to electro-
static discharges. They may be damaged if they are touched by
an electrostatically charged person or object. In the worst case
scenario, these components are instantly destroyed or go out of
order as soon as they are activated.
▶ To minimise or even avoid all damage due to an electrostatic
discharge, take all the precautions described in the EN 613405-1 and 5-2 standards.
▶ Also ensure that you do not touch any of the live electrical
components.

Type 1062
Description
5 DESCRIPTION
5.1 Area of application
The electrical position feedback, combined with a pneumatic valve,
is intended to signal the position - open or closed - of this valve.
The position of the valve is given:
• by light(s) and by electrical signal on the mechanical contact
versions, on the inductive 3-wire switch (1 output) or double
inductive 4-wire switch (2 outputs) or double inductive 2-wire
NAMUR switch (2 outputs)
• only by electrical signal on versions with inductive 2-wire switch (1
output).
5.2 General description
5.2.1 Construction
The electrical position feedback is composed of a housing, fitted
with a cable gland, with a transparent cover.
The housing includes:
- a duplication system that adapts to the pneumatic actuator rod
on the valve,
- one or two electronic boards, each fitted with a mechanical
contact limit switch or an inductive switch, with 2 or 3 lights
(except for the 2-wire inductive versions)
- a terminal block for electrical connection.
5.2.2 Principle of operation
The duplication rod fitted with 2 cams moves when the valve opens
or closes: the movement of a cam past the switch associated with it
activates the latter.
When the switch is activated, the light, if there is one, comes on (or
goes off on the NAMUR versions) and an electrical signal is transmitted remotely.
This signal is transmitted in accordance with the NAMUR standard
on one version of the 1062 ATEX.
