■ Orientation of the Display Module
The display can be rotated in 90-degree, thus guaranteeing easy readability even in unusual install 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 on the back, be sure to check the O-rings and sealing surfaces on the housing for damage and replace them if necessary.
• Then, screw the cover by hand, and make sure that the housing is tightly sealed again.
07
NOTE. Make sure that no moisture can penetrate into the device! The seals and sealing surfaces must not get dirty;
This is because any contamination may, depending on the particular application or location, lead to a reduction in the level of

■2-Wire (Current) HART System
1. Where the cabling is laid in a fixed position, a minimum bend radius
of 10 times the diameter must be observed. For flexible use,
the limit is 20 times the diameter.
2. In order to electrically connect the device with connector terminals,
the cover must be unscrewed. If the device has a display and
control unit, this unit must be carefully pulled out. Place it next to the
housing during installation so that there is no strain on any
connections. Afterwards, carefully plug it back in and make sure that
the connecting wires are not twisted or pinched. 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.
3. Use a shielded and twisted multi-core cable for the electrical connection.
An additional signal complying with the HART specification is superposed
on the analogue output signal. Configuration of the device can be carried
out with the aid of a HART communication device. WISE CONTROL Inc.
recommends a communicator by licensed HART for this purpose.
In order to ensure trouble-free operation, the following specifications should
be taken into account:
Maximum length of cable between measuring instrument and supply unit:
Where Lmax : Maximum length of the cable in [m]
Where U : Supply in [VDC] The Resistance must be at least 250 Ω.
Resistance R :
Rv
Cv
: Resistance of the cable together with the load
resistance in [Ω]
: Capacitance of the cable in [pF/m]

■Electrical Grounding
Power Connection
WARNING
Danger of Death from Electric Shock
Switch off the power supply before installing the device!
Connection Assignment Table:
Electrically connect the device in accordance with the specifications
given on the type plate. Refer to following connection table and the
connection diagram:
It is an internal grounding and external grounding as well as the right
terminal configuration. The recommended cable grounding wire is
AWG24 or higher.
When using the extension cable, it is necessary to use thicker
standard than the specified grounding wire. Use a washer to prevent
loosening during terminal operation and use a plated terminal lug to
prevent corrosion and the grounding point must be connected to a
building ground connection, floor ground, or groud bus bar. (Grounding
points must comply with national and local industrial safety and
electrical codes.)
NOTE. When using devices with connector terminals, implement connections
such that the separation distances are in compliance with standards and
connecting lines cannot become disconnected.

■ Display and Control Unit
A bar graph is included on the display; This shows the acting pressure as a percentage of the measuring range. The display indicates the
measured value, and allows configuration of the individual parameters using menus. The individual functions can be set using two
push buttons (accessible from the top). The device can be configured in site without opening the display and control module. In order to do so, the
metal plate (on top of the device) must be rotated to the rear after undoing the left screw.
From left to right, the two buttons are assigned to: Mark Left(Z), Mark Right(S)
Measured values on the displayed with up to Max.7-digit character string comprising letters and numbers.
Operation
The menu system is self-contained. It allows you to "browse" both forwards and backwards through the individual settings menus in order to reach the
desired setting item. All settings are permanently saved in a flash EP ROM, therefore, retained even after the supply voltage has been
disconnected.
