To ensure reliable and safe operation, the measuring amplifier must be operated in compliance with the specifications according to this technical description only. These regulations must also be observed if accessories, which have been ordered from Althen Mess- & Sensortechnik GmbH together with the measuring amplifier, are being used.
1.3.1 ATEX-Accreditation / EU-Type Examination Certificate There’s an EU-type examination certificate for the described amplifier for operating it in accordance with these regulations. EU-type examination certificate name: TÜV 99 ATEX 1469 Under section „ATEX Inspection Certificate” is a copy of the EU-type examination certificate. The specified data are by all means to be followed.
Possible cable-bound disturbances (i.e. noise) must be blocked very near the cable ends (evaluation unit) by suitable measures. Changes of the measuring system of any kind demand for the explicit approval of Althen Mess- Notice: & Sensortechnik GmbH. Changes of any kind done without that approval exclude all possible warranty and/or liability of Althen Mess- &...

4.1 Supply Voltage The supply voltage can be 18 … 28 VDC. But it is to be taken into consideration, that the supply voltage dictates the maximum load resistance. With a supply voltage of: …24 VDC the load resistance can be max. 500 Ohms. …18 VDC the load resistance can be max.
5 Mounting The inclination measuring system is to be mounted according to standard EN6079-14. The system has to be mounted, so that all labels are readable and all connections are within reach. The cable has to be laid effectively protected against damages. By false application and operation of the system there’s danger of explosion on site or surrounding area.
Amplifiers and measurement units manufactured and sold by Althen Mess- & Sensortechnik GmbH serve B2B purposes only. Therefore, those old appliances must not be given to the communal disposer, but must be given back to the seller or disposed of properly.
During operation of the system in an explosion hazardous environment the data of the „EU-Baumusterprüfbescheinigung“ are to be followed.
