WIKA operating instructions model T32.xS 9
WARNING!
To ensure safe working on the instrument, the operator
must ensure
■ that suitable first-aid equipment is available and aid is
provided whenever required.
■ that the operating personnel are regularly instructed
in all topics regarding work safety, first aid and
environmental protection and know the operating
instructions and, in particular, the safety instructions
contained therein.
WARNING!
When working during a running process operation,
measures to prevent electrostatic discharge from the
connecting terminals should be taken, as a discharge
could lead to temporary corruption of the measured
value.
The model T32.1S temperature transmitter should only
be used with grounded thermometers! The connection
of a resistance thermometer (e.g. Pt100) to the T32.3S
must be made with shielded cable. The shield must be
electrically connected with the housing of the grounded
thermometer. (drawings see chapter 6.1 “Grounding”)
The connection of a thermocouple sensor to the T32.3S
must be made with a screened cable. The shield must be
electrically connected with the housing of the grounded
thermometer and, additionally, grounded to the side of the
T32.3S. It should be ensured that there is equipotential
bonding on installation, so that no balancing current can
flow via the shield. Here, in particular, the installation
regulations for hazardous areas should be followed!
The enclosure is constructed from plastic. To prevent the
risk of electrostatic sparking the plastic surface should be
cleaned only with a damp cloth.
