2 Safety notes
- The head-mounted temperature transmitter must be set up and
operated in accordance with these Operating Instructions and the
relevant regulations and standards.
- The transmitter can be operated in device group II category 1 G
(zone 0), in II 2 G (zone 1) and in II 3 G (zone 2).
- If the transmitter is operated in II 2 G (zone 1) or in II 3 G (zone 2),
the sensor current circuit may be present in II 1 G (zone 0).
- If the transmitter is operated in II 1 G (zone 0), care must be taken
that inflammable vapor-air mixtures only occur within the atmo-
spheric conditions. If no inflammable mixtures are present, or ad-
ditional measures according to EN 1127-1 have been taken, the
devices may also be operated outside the atmospheric condi-
tions, in accordance with the manufacturer’s specifications.
- The transmitter must not be configured within the hazardous area
using the PC setup program.
- When configuring with the aid of a standard PC, the maximum
safe voltage (U
m
= 30V) must not be exceeded. The use of a bat-
tery-operated PC (notebook) is ideal.
For safety reasons (protection of Ex-relevant components), the
connection must only be made briefly, for configuration.
- The supply circuit must conform to the explosion protection
Ex ia IIC.
- For transmitters (case material PC, encapsulated material PUR) or
mounting heads, it must be ensured that the device materials are
compatible with the measured media.
