Safety Regulations:
Read these instructions before commis-
sioning the equipment!
The bar switchcontrol is designed for ope-
ration as an optical display for intermediary
and end positions from position indicators,
on industrial fittings. Just before reaching
the end position, an electrical signal is ge-
nerated, e.g. for feedback to the process
control point.
All of these units are to be installed only
by suitably qualified skilled personnel. The
hereby quoted regulations are to be strictly
adhered to.
Incorrect handling or non-adherence to the
designated usage can lead to the loss of
function of the unit described in this docu-
ment!
• Work on the bar switchcontrol must be
always s carried out without connection
to the voltage supply and under accep-
tance and adherence to the current na-
tional and international Safety Regulati-
ons. Also disconnect the compressed air
supply to the actuator!
• Before installing, i.e. commissioning the
unit described in this document, check
the technical parameters, especially the
electrical connection values of the ap-
plied sensors.
• Take note of the diagram on the inside
of the housing.
• A change in the actuator pivoting angle
requires renewed adjustment of the unit
described in this documentation.
• Do not mount the unit described in this
document with the cable glands pointing
upwards.
• The unit may only be operated when it is
correctly closed according to this docu-
mentation.
• In Ex-areas, adjustment work on the ope-
ned unities only to be carried out under
the following conditions:
•
You fulfil the authorised regulations
(informing the fire brigade etc.)
•
You follow exactly the local necessa-
ry protective measures! (Continuous
measurement of combustible at-
mosphere etc.)
•
You avoid electrostatic charges,
even the metallic housing on the
sensors.
• When laying cables in Ex-areas, make
sure you adhere to DIN EN 60079-14.
• In explosion-protected areas, it may be
necessary to provide direct sunlight
pro tec tion, to shield the surface of the
