Low Pressure sensor turns off PRESSURIZED INDICATOR Action taken on pressure failure Red = Pressure Low depends upon the user. Actions include:- Alarm and/or Trip Alarm and delayed trip Power turned off automatically without delay "Pressurized" signal absent i.e. "Alarm" ON Yes PRESSURIZED INDICATOR Low Pressure sensor turns on Green = Pressure OK Relief Valve opens Purge flow starts "Pressurized" signal to remote alarm switch No Purge Outlet flow above the minimum? Yes Purge Flow Sensor turns on Purge timer resets "Purging" Indicator Amber = Purge flow OK Black = Purge flow too low Purge timer starts automatically No Outlet flow still above the minimum? Key to functions Yes Purge timer times out Manual operation by the user Purge valve closes; Power Sw. signal ON Automatic operation by the system "Purge Complete" signal to electrical Power Switch Purge flow ceases; Relief Valve closes Optional operation (User decision) Purging Indicator turns Black as Purge flow falls below minimum Leakage Compensation starts THIS DRAWING IS REFERENCED TO EXPO CETIFICATION DRAWING EP99-2-3 Power on - Normal operation REV: 01 1:1 SCALE SURREY KT7 0RH UNITED KINGDOM Expo Technologies Limited MATERIAL 23/06/2010 DRAWN DATE: REV.
