General Installation Instructions - BD Sensors AX18-DPT200 Betriebsanleitung

Fit the protective cap back over the diaphragm immediately after dismounting the
device.
Treat the unprotected diaphragm with extreme care; it can be damaged very easily.
Do not apply any force to install the device so as to avoid damaging the device and
the system!
When installing outdoors or in humid environments, the following points should be
noted:
- The device should be electrically connected immediately after installation to ensure
that no moisture is able to penetrate into the plug connector, If this is not possible,
the ingress of moisture must be prevented by using a suitable protective cap. (The
protection class specified in the data sheet applies to the connected device.)
- Select an installation position that allows splashed water and condensation to drain
away. Ensure that sealing surfaces are not exposed to standing liquid!
- When using devices with a cable outlet, the outgoing cable should be routed down-
wards. If the line must be routed upwards, this is to be achieved by bending it
through a downward-pointing arc.
- Install the device such that it is protected from direct sunlight. Direct exposure to
sunlight may, in the worst case, cause the maximum permissible operating tem-
perature to be exceeded. The possibility of this happening must be eliminated when
the device is used in Ex areas!
When the device is connected to the pressure chamber, the user much ensure
proper sealing.
Check that the envisaged or, if applicable, supplied seals are compatible with the
medium used. If it is not possible to guarantee compatibility, other suitable seals
must be employed.
Take care that the pressure connector is not subjected to any mechanical stresses
higher than those permitted during installation, since this could cause the character-
istic to shift or result in damage. This applies particularly to very small pressure
ranges.
In the case of hydraulic systems, orient the device such that the pressure connector
faces upwards (for venting).
Provide a cooling section when using the device in steam lines.

4.2 General installation instructions

- Carefully remove the device from its packaging and dispose of the packaging prop-
erly.
- Then proceed as described in the following installation instructions.
It should be noted here that (for DPT 200):
- The higher pressure must be connected to the "+" input.
- The lower pressure must be connected to the "-" input.
