8.5.7.4. Valve Control
The relay board also hosts two valve driver chips, each of which can drive up four
valves. The main valve assembly in the 9110TH/M is the NO/NO
X
- Auto-zero solenoid
valve assembly mounted right in front of the NO
2
converter housing. These two valves
are actuated with 12 V supplied from the relay board and driven by the CPU through the
I
2 C bus.
A second set of valves may be installed if the zero/span valve is enabled in the analyzer.
Specialty manifold valves may be present in the analyzer.
