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
The housing and the cover cap of the pressure monitoring device consist of
lightweight, corrosion-resistant metal.
