WIKA operating instructions model T32.xS 8
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.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
■
The instrument may only be installed and mounted by skilled personnel.
■
Operation using a defective power supply unit (e.g. short circuit from the
mains voltage to the output voltage) can result in life-threatening voltages
at the instrument!
WARNING!
Only instruments as described in chapter 4.2 “Operation in safety-related
applications” are qualified for use in safety-related applications. Do not use
other instruments in safety or Emergency Stop devices.
Incorrect use of the instrument can result in injury.
