1 .1 .3 TC 116W with two-stage combination control
CG . .Z
Tightness control TC 1 checks gas solenoid valves V1 and
V2 in combination control CG..Z for tightness.
Once the tightness test has been carried out successfully,
the tightness control forwards the OK enable signal to the
automatic burner control unit GFA. The pilot valve output
of the automatic burner control unit GFA opens valves V1
and V2 in the combination control simultaneously. The
burner starts. The main valve output opens the two-stage
valve VZ, independently of TC 116W.
V1 and V2: quick opening valves.
