2. Safety
2.3 Special hazards
WARNING!
■ Pressure sensors should only be fitted or removed when the system
is free from pressure.
■ Observe the working conditions in accordance with chapter
3 "Specifications".
■ Always operate the ProcessCalibrator within its overload limits.
■ Residual media in a dismounted ProcessCalibrator can result in
a risk to persons, the environment and equipment. Take sufficient
precautionary measures.
■ Do not use this ProcessCalibrator in safety or Emergency Stop
devices. Incorrect use of the ProcessCalibrator can result in injury.
■ Should a failure occur, aggressive media under high pressure or
vacuum may be present at the ProcessCalibrator.
■ Plan the wiring especially carefully when connecting to other
devices. Under certain circumstances, internal connections in
third-party devices (e.g. GND connected to the ground) can lead to
impermissible voltages that could compromise or even destroy the
function of the device itself or a device connected to it.
■ To ensure problem-free operation, only operate the
ProcessCalibrator on battery power. Only use the mains connection
for charging the ProcessCalibrator's batteries.
■ Only use the sensor cable available from WIKA for the
ProcessCalibrator. Do not connect any cable over 3 m long to the
CPH6000.
■ The measurement signal of the reference (or test sample) can be
influenced by large electromagnetic effects and the display of the
signal may be lost completely.
■ The display screen is made from glass. If there is any possibility of
the screen breaking during operation, all personnel in the vicinity of
the instrument must wear eye protection before and during its use.
■ If the CPT6000 reference pressure sensor is used in applications
with oil as a pressure medium, make sure it is not be used with
flammable material or gases directly afterwards, since this can lead
to dangerous explosions and a risk to personnel and machinery.
