USER MANUAL CODIX 531 Kübler

1 Short description This digital display is an easy-to-use, microprocessor-con-

rolled 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-

ff, 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.

he 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-

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. !12 3 Mounting

3.1 Installation1. The digital display shall not be installed near to contac-tors or motor starters.

. We recommend the use of wire end ferrules in order toavoid short-circuits between adjacent terminals.3. In order to keep the interferences at the measuring inputas low as possible, the signal and power supply wiresmust be routed separately. . Use shieded cables for all signal/probe wirings and avoid2. The display shows the following message.

5.1 Switching to programmingTo switch to the programming mode: 1. switch the power supply of the device off, press simulta-neously both keys on the front side, and then switch thepower supply on again.

Unit Selection in the menu Display in °C Display in °F positive or negative. The input is always made with one de- cimal place.

5.4.6.1 Resetting the maximum value

This allows defining whether the maximum value can be reset during operation or not. However, the maximum value can only be reset if the maximum value display is the active function (see 6.1). If the maximum value is reset, the cur- rent measured value becomes the new maximum value. Selection in the menu The maximum value can be reset using the red key The maximum value cannot be reset

6.1 Switching the display during operation

press the right-hand/grey key to select among the following functions: –current measured value –minimum value –maximum value. Press the key once to display the designation of the active display function for 2 seconds. If, during this time, the right- hand grey key is pressed a second time, the display swit- ches to the following display function. This is confirmed by a 2-second display of the designation of the new function. After these 2 seconds, the display shows, depending on the selection, the maximum value, the minimum value or the current measured value.

6.2 Saving the momentary value (Display-Latch)

In case of a High Signal at the Latch input, the current mea-

ured value is frozen on the display. The minimum and ma- ximum value acquisition continues operating in the background. 7 Troubleshooting and alarm messages
