General Installation Instructions - BD Sensors LPT 200 Betriebsanleitung

Take care that the pressure connector is not subjected to any mechanical stresses
higher than those permitted during installation, since this could cause the
characteristic 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
properly.
- Then proceed as described in the following installation instructions.
It should be noted here that (DPT 200):
- The higher pressure must be connected to the "+" input.
- The lower pressure must be connected to the "-" input.
4.3 Installation steps for DIN 3852
DO NOT USE ANY ADDITIONAL SEALING MATERIALS, LIKE YARN, HEMP OR
TEFLON TAPE!
- Check to ensure the proper groove fitting of the o-ring and additionally to ensure no
damage to the o-ring.
- Ensure that the sealing surface of the taking part is perfectly smooth and clean.
(RZ 3.2)
- Screw the device into the corresponding thread by hand.
- Devices with a spanner flat have to be tightened with an open-end wrench (wrench
size of steel: G1/2": approx. 10 Nm).
- The indicated tightening torques must not be exceeded!
4.4 for NPT connectors
- Additional seal materials, e.g. PTFE tape, may be used to provide sealing.
- Screw the device into the mounting thread by hand.
- Then tighten it with the open-end wrench (for 1/4" NPT: approx. 30 Nm; for 1/2"
NPT: approx. 70 Nm).
- The specified tightening torques must not be exceeded!
4.5 Orientation of the display module
The display can be rotated in 90-degree steps, thus guaranteeing easy readability even in
unusual installation locations. In order to change its position, proceed as follows:
- Unscrew the housing cover by hand.
- Completely unscrew the two cross-head screws on the front side of the display
module. Pull the display module forwards and off, rotate it through 90°, 180° or
270°, and carefully plug it back on again. Reattach the display module with the two
screws.
- Before screwing the cover back on, be sure to check the O-rings and sealing
surfaces on the housing for damage and replace them if necessary!
- Then screw the cover on by hand, and make certain that the housing is tightly
sealed again.
