Short Circuit - Tecsis EGS08 Betriebsanleitung

Betriebsanleitung/Operating manual
EGS08
When using tecsis force transducer with test relay (4... 20mA – 2 wire for SIL3-
application), by the connection of the contact clamp 3 at the connection port X2
(activation test relay for signal leap) is released by the factory with the mass
(GND), that at the force receiver after customer's request stopped signal leap.
The standard settings of the force transducer with current exit 4... 20 mA for
overload detection e.g. is:
4
3,8
cable break
With a firmly stopped signal deviation of 8 mA in each operating condition on
activation of the test relay the point of overload is then exceeded. The upper
measuring range border of 20 mA is not reached however and thus the
examination of the signal deviation is made possible (see in addition for further
information also the data sheets of the appropriate tecsis force transducers).
