The pressure monitoring device responds to large pressure increases faster
than the protective relay. The protective relay is part of the standard MR pro-
tection system and comes as standard.
Additional use of a pressure monitoring device also requires installation of
the provided protective relay.
The features and characteristics of the pressure monitoring device comply
with the respective applicable version of IEC publication 60214-1.
Diverter switch operations at the rated switching capacity or permitted over-
load do not cause the pressure-operated relay to trip.
The pressure-operated relay responds to a pressure change and not to gas
accumulation under the pressure-operated relay. Gas accumulation under
the pressure-operated relay is normal.
3.1.4.2.2 Design/versions
There are two variants of the pressure monitoring device:
▪ DW 2000 for vertical installation
▪ DW 2000 for horizontal installation
