Page 6: General
3. General 3. GENERAL Congratulations on your purchase of this new and innovative ALMEMO ® mea- suring instrument. Thanks to the patented ALMEMO ® connector the device configures itself automatically; its operation should be fairly straightforward. The device can, however, be used with a wide range of sensors and peri- pherals and offers many different special functions. -
Page 7: Waste Disposal
Waste disposal 3.3 Waste disposal This symbol means that the product is subject to the European Union’s segregated waste disposal regulations. This applies both to the product itself and to any accessories marked with the same symbol. Disposal of any such item as unsorted dome- stic waste is strictly forbidden. -
Page 8: Introduction
5. Introduction 5. INTRODUCTION Panel meter ALMEMO ® 4390-2 is a new member in our family of unique mea- suring devices - all equipped with Ahlborn's patented ALMEMO ® connector system. The intelligent ALMEMO ® connector offers decisive advantages when connecting sensors and peripherals because all parameters are stored in an EEPROM located on the connector itself;... -
Page 9: Sensor Programming
Functions 5.1.1 Sensor programming The measuring channels are programmed, completely and automatically, via the ALMEMO connectors on the sensors. However, the user can easily sup- ® plement or modify this programming via the keypad or via the interface. Measuring ranges Appropriate measuring ranges are available for all sensors with a non-linear characteristic, e.g. -
Page 10: Measuring Operation
5. Introduction Limit values and alarm Per measuring channel two limit values can be set (1 maximum and 1 mini- mum). In the event of one of these limit values being exceeded an alarm con- tact is actuated by the internal relays; these can be allocated individually to specific limit values. -
Page 11: Process Control
Functions Maximum and minimum values For each measuring operation the maximum value and minimum value are ac- quired and saved to memory. These values can then be displayed, output, or deleted from memory. 5.1.3 Process control To record the measured values from the connected sensors in digital form measuring point scanning is performed continuously with measured value out- put according to a time-based process control. - Page 12 5. Introduction connector (available as an accessory) files can be read out very quickly via any standard card reader. Output All data logs, measured values, and programming parameters can be output to any peripheral equipment. Using the appropriate interface cables RS232, RS422, USB, and Ethernet interfaces are available.
