Important information for the installed REGARD
system!
Dräger recommends that the Dräger RVP 5000 is only
used in conjunction with a REGARD system consisting
of ATEX channel cards (software revision 3.0). Using a
REGARD 8-channel card software revision 2.5 will
have following effect:
If the 8 channel card is set to latch when full scale
deflection (FSD) is reached this will not be shown on
the RVP 5000 after the input signal falls back into the
normal measuring range. The Dräger RVP 5000 will
show the measuring range instead of the FSD status
that's still displayed on the REGARD system.
