2 Safety notes
- Setting up and operation of the head-mounted temperature trans-
mitter must be performed with the help of these operating instruc-
tions and the regulations and standards relating to it.
- The head-mounted temperature transmitter may be operated in
equipment group “II” category “1 G” (Zone 0), in “II 2 G” (Zone 1)
and in “II 3 G” (Zone 2).
- If the head-mounted temperature transmitter is operated in
“II 2 G” (Zone 1) or in “II 3 G” (Zone 2), the sensor circuit may
be placed in the “II 1 G” area (Zone 0).
- If the head-mounted temperature transmitter is operated in
“II 1 G” (Zone 0), care must be taken that potentially explosive
air/vapor mixtures only occur in atmosperic conditions. If no
potentially explosive mixtures are present, or if additional measu-
res have been taken according to EN 1127-1, the instruments
may also be operated outside the atmospheric conditions, in
accordance with the manufacturer’s specifications.
If the operating conditions at the head-mounted temperature
transmitter differ from those stated above, it must be noted that
the transmitter (also in the event of a fault) does not warm up
above 20 °C and that the operator is responsible for the safe
operation of the system with regard to pressures / temperatures
of the materials used.
- The configuration of the transmitter using the PC setup program
via HART
®
modem may not be performed inside the hazardous
area.
- The supply circuit must fulfil explosion protection Ex ia IIC. This is
ensured by an Ex-i power supply/input isolating amplifier 707530.
