•Falling parts (bolting, floats etc.) can create impact sparks and cause explosions in an
explosion-prone atmosphere. Make sure that an explosion-prone atmosphere does not exist
and no parts fall down when working on the magnetic level indicator.
•When working on the magnetic level indicator, use only equipment and tools which were
approved for the explosion-prone area.
•Polycarbonate indicator rails can be electrostatically charged, e.g. during cleaning. When
discharging, sparks can cause explosions in an explosion-prone atmosphere. Please clean the
parts only with anti-static cleaning agents and auxiliary tools.
3. Intended use
•The transmitters may only be used in connection with original WEKA magnetic level indicators
and their individual parts, e.g. floats.
•The transmitters may only be used for the intended use indicated on the type plate. The data
recorded on the type plate and the data sheet must correspond to the maximum operation
parameters occurring within the plant.
•Intended use, rebuilding measures and alterations of the transmitters not provided by the
manufacturer are carried out at one’s own risk and are potentially dangerous (exclusion of
warranty).
•The transmitters may only be installed, commissioned and maintained by trained specialist
staff.
•The manufacturer is not liable for damages which are caused by improper use or incorrect
operation.
•The transmitters are classified according EN 61140 to protection level II and will be high
voltage tested for 100% each.
•The transmitters may only be used for the intended use indicated on the type plate and the
labelling according to Directive 2014/34/EU and/or IECEx.
•The transmitters may only be installed, commissioned and maintained by trained specialist
staff with knowledge on EX protection.
•The transmitters may only be repaired and modified by the manufacturer (where required in
