1 Short description

This digital display is an easy-to-use, microprocessor-controlled device for the display (and the acquisition) of measured temperature values. The temperatures are measured by means of J, K and N thermoelectric couple sensors. They can display either the current measured value, the maximum 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 intended 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 correctly mounted in a panel, in accordance with the chapter "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 industrial processes and controls, in the branch of the manufacturing 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 processes 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.

3 Mounting

3.1 Installation

1. The digital display shall not be installed near to contactors or motor starters.
2. We recommend the use of wire end ferrules in order to avoid short-circuits between adjacent terminals.
3. In order to keep the interferences at the measuring input as low as possible, the signal and power supply wires must be routed separately.
4. Use shielded cables for all signal/probe wirings and avoid routing the signal/probe wirings parallel to each other.
   The shield shall only be grounded at one point in order to avoid ground loops.

5.1 Switching to programming

To switch to the programming mode:

1. switch the power supply of the device off, press simultaneously both keys on the front side, and then switch the power supply on again.

1. The display shows the following message.

1. release both keys. The first parameter to be set appears on the display. The display switches every second between the following messages

t h.t y P 1 s 3

1. press the left key to stop the display from switching. The last programmed parameter setting is displayed.

5.2 Changing the parameter setting

1. press the right-hand/grey key to change the parameter setting by one value at a time

1. to input numerical values, select first the decade with the left-hand/red key

5.4.2 Reference point compensation

A thermoelectric temperature measurement measures a (thermoelectric) voltage generated by a thermoelectric couple. The value of the thermoelectric voltage depends on the temperature difference between the measured point and the reference point.

In order to define accurately the temperature at the measured point, the temperature of the reference point must be constant and/or known. To do so, the internal and external reference points are differentiated.

For the internal reference point compensation, the device is fitted with an internal temperature sensor that measures the current temperature of the terminal. This temperature is 4. set now the numerical value using the right-hand/grey key

1. to reach the following decade, press the left-hand/red key

1. if negative numerical values are required, set the left decade to “-” or “-1”.

2. and press simultaneously the right/grey key..

used to compensate the measured thermoelectric voltage. This measuring method requires to connect the sensor with the terminal of the display by means of appropriate compensation lines. These terminals are the internal compensation point.

When using the external reference point compensation, the temperature of the reference point is maintained at a constant and known value by means of appropriate measures. The temperature sensor ist connected with the device, which is set to the constant temperature of the reference point, by means of a simple copper wire.
