OPERATING MANUAL TMU / UMC3
7.
Operation
Control unit BE4
Introduction
The UMC3 transmitter can be operated using control unit BE2, a desktop or laptop computer in conjunction
with SensorPort software, or via HART
®
Communicator.
In the following, transmitter operation and parameterization using control unit BE2 (normally integrated into
the terminal compartment) are described. The control unit can also be connected to the transmitter using an
intrinsically safe cable that is up to 200 m in length. This allows a point-of-use display to be installed in a
control room so that readings, counter status and settings can be accessed ergonomically.
Control Unit BE2
The BE2 Control unit of the UMC3 has an integrated alphanumeric display with two 16-character lines
(format 16 x 60 mm). Measurement data and settings can be read directly from this display.
The LCD display is designed for operation at temperatures ranging from − 20 °C to + 60 °C (-4° F to 140 °F)
without incurring any damage. However, at freezing or near-freezing temperatures, the display becomes
slow and readability of the measured values is reduced. At temperatures below − 10 C° (14 °F), only static
values (parameter settings) can be displayed. At temperatures exceeding 60 C° (140 °F), contrast decreases
substantially on the LCD and the liquid crystals can dry out.
