Requirements on the personnel's qualification
Designated users
The FLSE100-XT sender/receiver units may only be installed and operated by skilled
technicians who, based on their technical training and knowledge as well as knowledge of
the relevant regulations, can assess the tasks given and recognize the hazards involved.
Skilled persons are persons according to DIN VDE 0105, DIN VDE 1000-10 or IEC 60050-
826 or directly comparable standards.
The named persons must have exact knowledge of operational hazards caused, e.g., by low
voltage, hot, toxic, explosive gases or gases under pressure, gas-liquid mixtures or other
media as well as adequate knowledge of the measuring system gained through training.
Specific requirements for use of devices in hazardous areas
NOTICE:
Observe the ambient temperature
Be aware that the ambient air around the pipeline might heat up.
● The ambient temperature around the electronic housing may not exceed
+70 °C for the sender/receiver unit marked with T4.
● The ambient temperature around the electronic housing may not exceed
+55 °C for the sender/receiver unit marked with T6.
The compliance with these requirements is the sole responsibility of the user.
A temperature fuse protects the transmitter/receiver unit electronics against
impermissible high temperatures. The temperature fuse interrupts the function
of the electronics should such high temperatures occur. The switch-off
reaction of the temperature fuse is permanent and can only be reset by the
manufacturer through repair.
