The general operating instructions of all devices as used must be
abided by.
Measures must be taken preventing personal injuries and damage to
property from occurring in case of a defective condition of the bypass
level indicators.
The bypass level indicator must not be operated in the direct vicinity of
ferromagnetic environments (min. distance 50 mm) or strong electroma-
gnetic fields (min. distance 1 m).
The bypass level indicator must not be exposed to heavy mechanical
strain.
The maximum power and voltage values for the intrinsically safe opera-
tion as specified in the assembling and operating instructions should be
adhered to.
The safe operation of the system with a view to
pressure and temperature of the materials as emplo-
yed shall be the operator’s responsibility.
The medium to be monitored must not be heavily soiled
or contain coarse particles. It must not tend to stick or
crystallise, as otherwise the perfect function cannot be
guaranteed.
The bypass level indicators may only be used in accordance
with the maximum values for pressure and temperature as
stated on the product label. Exceeding these parameters
can lead to malfunctions or to the destruction of the bypass
level indicator and may cause personal injury or damage to
property. All materials of the bypass tube and the float must
be resistant to the medium to be monitored.
