Filter change (menu)
Function
The “Filter change” menu function assists you during maintenance work on the sample gas
filter in two steps:
a) Safeguarding before starting maintenance:
– The supply of instrument air to the ejector pump is stopped. As a result the ejector
pump is deactivated; the supply of sample gas to the measuring system is stopped.
– The supply of fuel gas is stopped, the FID flame is extinguished.
–
On devices with the “flow barrier” option:
The external solenoid valve is activated;
as a result the sample gas in the sample gas filter is displaced by instrument air.
b) Safe restart:
– The sample gas filter is heated to operating temperature; this prevents
condensation.
– The FID flame ignites again.
–
On devices with the “flow barrier” option:
The external solenoid valve is deactivated.
– The sample gas supply is activated again.
