Type 1062

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 trans-
mitted remotely.
This signal is transmitted in accordance with the NAMUR standard
on one version of the 1062 ATEX.
