1 Short description
This digital display is an easy-to-use, microprocessor-con-
trolled device for the display (and the acquisition) of measu-
red temperature values. The temperatures are measured by
means of Pt100 or Ni100 resistance thermometers. They
can display either the current measured value, the maxi-
mum value or the minimum value. In case of power switch-
off, the maximum and minimum values are stored in an
EEPROM. The values are restored as soon as the display
is powered again. The Latch input is isolated electrically
from the signal input by means of an optocoupler. It allows
storing the current measured value.
The supply voltage (10 .. 30 V DC) is isolated electrically
from the signal input by means of a DC/DC converter.
2 Safety instructions and warnings
Only use this display
– in a way according to its intended purpose
!
– if its technical condition is perfect
– adhering to the operating instructions and
the general safety instructions.
1. Before carrying out any installation or maintenance
work, make sure that the power supply of the digital display
is switched off.
2. Only use this digital display in a way according to its in-
tended purpose.
3. If its technical condition is perfect.
4. Adhering to the operating instructions and the general
safety instructions.
5. Adhere to country or user specific regulations.
6. The digital display is not intended for use in areas with
risks of explosion and in the branches excluded by the
standard EN 61010 Part 1.
7. The digital display shall only operate if it has been cor-
rectly mounted in a panel, in accordance with the chap-
ter "Main technical features".
2.1 Use according to the intended purpose
The digital display only may be used as a panel-mounted
device. Applications of this product may be found in indu-
strial processes and controls, in the branch of the manufac-
turing lines for the metal, wood, plastics, paper, glass,
textile, etc., processing industries.
Overvoltages at the terminals of the digital display must be
limited to the values of overvoltage category II.
If the digital display is used to monitor machines or proces-
ses in which, in case of a failure of the device or an error
made by the operator, there might be risks of damaging the
machine or causing accidents to the operators, it is up to
you to take appropriate safety measures.
