nameplate for plug or cable assignment and, if applicable the installation guidelines of
the cable, are to be observed.
WARNING!
An incorrect or incomplete electrical connection impairs or prevents
measurement.
e) Functional test: After the mechanical (see c) and electrical (see d) installations are com-
pleted, the sensor is to be moved over the entire designated measuring range; the out-
put measurement signals are to be subjected to a plausibility check.
WARNING!
If, due to unusual observations (e.g. deformation or unusual noise),
measurement results are considered implausible or there is suspicion that the sensor is
malfunctioning for any other reason, it may not be put into operation.
2.2.2 Additional information for Type 0813 operation in areas subject to explo-
sion hazards
Only those sensors with the corresponding labels are approved for use in areas subject to explo-
sion hazards.
If the open cable end is connected inside an area subject to explosion hazards, the connec-
tion must be inside a terminal box/switching cabinet certified in accordance with directive
94/9 EC. If it is connected outside an area subject to explosion hazards, it must be in line
with the general requirements for electrical equipment.
Close attention must be paid to the connection of the potential equalisation.
Cables supplied by BROSA are approved for use if they are fastened (strain-relieved) in are-
as subject to explosion hazards.
2.3 Operation and maintenance
2.3.1 Operation
BROSA angle sensors operate automatically; the attaching of tools is not necessary for op-
eration. Direct manual intervention by the operator is not necessary; there are therefore no
requirements for the operator to wear protective equipment during operation. However, the
relevant requirements for the device in which the angle sensor is implemented must be ob-
served.
BROSA angle sensors emit neither airborne acoustic noise nor non-ionising radiation.
BROSA angle sensors may not be opened during operation.
Operation of BROSA angle sensors is permitted only within the framework of the parameters
and properties given in the technical data sheets and on the nameplate. These are, among
others:
-
Measuring range
-
Temperature range
-
Permissible supply voltage
-
Electrical protection class
-
Material
Tilting away from the measuring plane leads to falsification of the measurement results and
is therefore to be avoided.
