NOTE:
Hazard during operation in the Ex-zone
Risk of explosion when regulations on explosion protection are not observed during
operation.
▸
Only use the measuring system in the Ex-zone according to the device marking (
).
▸
Only use the measuring system within the temperature limits as specified in these
Operating Instructions as well as on the type plate.
The specified values must not be exceeded even for brief periods.
▸
The use of the measuring system with hybrid mixtures (mixture of combustible gases
or vapors with dust) must be evaluated according to the situation being considered,
e.g. regarding concentration limits or energy and temperature limits.
▸
Do not install any components, apart from the electronics unit of the sender/receiver
unit, in lines, tanks, or other installation areas where explosive gas and/or dust
mixtures may be present.
▸
The measuring system must not be operated with dust deposits thicker than 5 mm
on the electronics housing.
▸
Dust deposits must be removed regularly and properly.
