Intended use of the device

The gain and displa$ s$stem oltage LYBRA REV.2 was designed so that it is in the interior of the

control cabinet of the machine to the 2%" rail can be integrated.

%t has a displa$ and a #e$board for programming and calibration.The deice receies the signal from the pressure gaugeCn (m/ or mA) feels that it amplifies it (b$

including it in a signal in / or mA is conerted) and uses it to the pressure measuring oltage measured

doses. %t is also eDuipped with two alarms, whose actiation thresholds and distances can be selected.

The deice is not suitable for outside, in corrosie, e7plosie or dust$ rooms to wor#.

The displa$ shows the captured 6ugwert! the #e$board with switches enables the access to the

programming, calibration and control of all parameters.2ispla$ 3assword

AlarmThe alarms are actiated when the registered train within the selected actiation distances. %f the alarms

are enabled, close the internal opto-isolated switch (normall$ open) between terminals 5-0> and 05-00

and the displa$ changes the displa$ of the acDuired train with the te7t GA.5G and GA.0G.
