General Warnings Concerning Pressure Measurement - BEAMEX MC5-IS User Manual

Safety
been possible without affecting the accuracy. The circuits are
designed so, that you can connect a voltage source 30VDC/
215mA or max. 1 W between any terminals without damaging
the device. However, long exposure to this kind of stress may
affect the accuracy.
Although there is a galvanic isolation between MC5-IS' ET and
E modules, it is for functional purposes only. The max. 30 V
restriction applies between these modules too.
Maximum output voltage from MC5-IS' terminals is below 16 V.
If you, however, connect together voltages from the ET and E
sections or if you connect external voltages to MC5-IS, the re-
sulting voltage may be high enough to be hazardous.

General Warnings Concerning Pressure Measurement

The accessory polyurethane hose supplied with an MC5-IS with
pressure modules is rated to the maximum pressure of 20 bar
at 21°C (290 psi at 70°F). Applying higher pressure can be haz-
ardous.
To avoid damaging the calibrator, use hand tightening only
when connecting the pressure measurement hoses (max.
torque 5 Nm). If the use of tools is required to secure the connec-
tion (typically pressure modules with a pressure range of 20
bar or more), apply the counterforce with a spanner on the con-
nector body's hexagonal part.
Always depressurize the system before opening or connecting
any pressure fittings or connectors. Use proper valves for vent-
ing the system. Ensure that all connections are made correctly
and that the hose and the connectors are intact.
Always use the pressure media stated in the module's sticker.
Using unsuitable pressure media may destroy the pressure
module. The internal module's sticker is located at the rear of
MC5-IS. External modules have the sticker on the module it-
self.
Never exceed the maximum pressure of a pressure module, be
it internal or external. The pressure module's maximum pres-
sure is stated on the module's sticker. The maximum pressure
of external modules is also mentioned in the Instruction Leaf-
let that is provided with the external module.
Never plug a hose with your hands or put the hands in front of
a gas spray coming from a leakage. A gas bubble in the blood
circulation can cause death.
