Page 4: Safety Instructions
General dangers in the case of non-observance of the safety instruc- tions The ME50S6 complies with the state of the art and is operationally reliable. If the device is used and operated inappropriately by untrained personnel, resid- ual dangers might develop. - Page 5 • When cleaning, please ensure that no liquid finds its way into the device or onto the contacts. Residual dangers The ME50S6 scope of performance and supply covers part of the measuring- technology, only. The plant designer/constructor/operator must in addition de- sign, realise and take responsibility for the measuring-system’s safety such that potential residual dangers are minimized.
- Page 6 ME50S6 If there is any risk of remaining dangers when working with the, it is pointed out in this introduction by means of the following symbols: DANGER Symbol: Meaning: Maximum danger level Warns of a decidedly dangerous situation in which failure to comply with safety requirements can lead to death or serious physical injury.
- Page 7 Do only quit error messages if the reason for the error has been eliminated and there is no more danger. Reconstruction and modifications HBM’s express consent is required for modifications regarding the ME50S6 construction and safety. HBM does not take responsibility for damage result- ing from unauthorized modifications.

Page 14: Individual Settings
ME50S6 Individual Settings Various ex-works settings on the measuring amplifier card can be altered. Adaptations, which are of no problem, can be carried out by means of the DIP switch on the board or also by externally wired switching elements. If re- quested with the order, they can be carried out by the manufacturer. -

Page 16: Calibration Signal
... pin 24c 4.5 Calibration Signal The measuring amplifier ME50S6 operates on a 6-wire technique, i.e. the cal- ibration and zero compensation signals are formed from the bridge supply voltage fed back; thus they are independent of transducer, connecting cable and pin resistances. -
Page 17: Synchronization
ME50S6 4.7 Synchronization When synchronizing several units of the type ME50S6 one of them has to be switched as master; its carrier frequency is used for reference. Pins 12c and 15c of all amplifiers concerned must be joined for synchronization. The master amplifier is selected by switch S28. -

Page 20: General Notes
Certain regulations concerning electrical installation have to be observed in plants with strongly disturbed supply mains systems. The most important points are listed up in the HBM leaflet ” Hints for connection/disturbances”. An extensive summary is given in the installation regulations VDI/VDE 3551. The extent of certain measures to be taken depends on the specific applications. -
