Info

The external components required for automatic / manual purging are:• A mains voltage (240 or 110 VAC) purge solenoid valve• A purge pressure switch, 0 to 35 kPa (0 to 5 psi), to test for filter blockage.The user should supply:• Span gas cylinder(s), typically 2% oxygen in nitrogen or a similar percentage of O2 close to the normal level in thegas stream being measured, to ensure fast recovery.• A 100 kPa (15 psi) clean and dry instrument air supply when filter purging is required.1.4 FILTER PURGE PRESSURE SWITCHTo automatically sense a blocked probe filter, a pressure sensor should be connected to the ‘purge’ line to the probe‘cal’ port. It should be adjusted so that it energises just above the purge pressure with a new or clean filter installed.The switch contacts should be connected to terminals 12 & 13 (PURGE FL SWITCH).If the filter is still blocked or partly blocked after an auto purge cycle, the pressure switch will energise and cause a‘Probe Filter Blocked’ alarm. The contacts must be normally closed.The pressure switch should have an adjustable range of 0 to 100 kPa (0 to 15 psi).August 200912 1633 Combustion Controller
