1 Safety Instructions
10 Series 275 Convectron Module with DeviceNet
Instruction Manual - 275502
Using the N
2
calibration to pressurize a vacuum system above about 1
Torr with certain other gases can cause dangerously high pressures which
may cause explosion of the system. See Chapter 6, Calibration, before
using with other gases.
Warning − If used improperly, Mini−Convectron Gauges can supply
misleading pressure indications that can result in dangerous
overpressure conditions within the system.
Do not operate in an explosive atmosphere.
Do not operate the product in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment
constitutes a definite safety hazard.
Do not use the product to measure the pressure of explosive or
combustible gases or gas mixtures. The sensor wire of the
Mini−Convectron Gauge normally operates at only 125 ˚C, but it is
possible that Controller malfunction can raise the sensor temperature
above the ignition temperature of combustible mixtures.
Danger of explosion or inadvertent venting to atmosphere exists on all
vacuum systems which incorporate gas sources or involve processes
capable of pressurizing the system above safe limits.
Vacuum gauges with compression fittings may be forcefully ejected if the vacuum system is
pressurized.
It is the installer's responsibility to ensure that the automatic signals provided by the product are
always used in a safe manner. Carefully check manual operation of the system and the set point
programming before switching to automatic operation.
Where an equipment malfunction could cause a hazardous situation, always provide for fail-safe
operation. As an example, in an automatic backfill operation where a malfunction might cause high
internal pressures, provide an appropriate pressure relief device.
