GB-2
Checking the usage
TC
Tightness control for checking two safety valves be-
fore and after burner run, with adjustable measure-
ment time for adjustment to different test volumes,
leakage rates and inlet pressures. The TC is used in
industrial thermoprocessing equipment, on boilers
and on forced draught burners.
TC 1, TC 2
For gas solenoid valves, quick opening or slow open-
ing with start gas rate.
TC 3
With fitted auxiliary valves for quick or slow opening
gas solenoid valves as well as for motorized valves.
This function is only guaranteed when used within the
specified limits– see page10 (Technical data). Any
other use is considered as non-compliant.
