of the inlet valve. Ensure that connections p
u
and p
z
on the TC and the gas solenoid valve
are not reversed.
▷ TC and bypass/pilot gas valve cannot be fitted
together on the same side of the double block

▷ When using a valve/pressure regulator combi-
nation VCG/VCV/VCH, the pressure regulator
must be activated with air during the entire test
periodt
