Rechner Sensors KAS-70 Notice D'utilisation page 11

Description
The power supply units generally have to be mounted outside the hazardous endangered areas. The
sensor has an LED visible from outside, which displays the operating state.
For KAS only: The sensitivity adjustment is made by means of a potentiometer or EasyTeach wire ac-
cessible from outside.

Potential compensation:
Sensors with a metal housing have a cable connection with a protective conductor (yellow-green). This is
an internal galvanic connection to the metal housing. The protective wire must be connected.
Please note: The conditions of the EN 60079-26:2007 e. g. relating to dust-coating and temperatures
must be met.
The sensor must not be powered when making the initial connection! Wrong connection can
destroy the sensor!
+ = Brown
Output 1 = Black
The sensor has an internal high-speed fuse of 200 mA. It is not possible to replace the
fuse. An external back-up high-speed fuse of 100 mA can be connected for protection of
the sensor.
