6.4.1 The purpose of the control panel is to monitor GASMIZER system operations during a
dive. The front panel layout is shown below.

Schematic of Control Panel
6.4.2 The major components are as follows:
1. Diver supply pressure gauge – indicates supply pressure available to the main
umbilical.
2. Sample flow meter – monitors the sample gas flow to an external gas analyser.
3. Exhaust hose pressure gauge - indicates pressure in the main umbilical exhaust
hose.
4. BPR loader pressure gauge – indicates the pressure set on the (surface) BPR
loader.
5. Hour meter – indicates the elapsed time that the system has been running.
6. No flow sounder – sounds when gas flow stops.
7. Fuse holder – contain 3 amp fuses for protection of the 12 volt DC power system.
8. Power switch/flow light – when depressed, the 12 volt DC system is energised.
When the green light is on, gas is flowing through the system.
9. Mute switch/no flow light – when the alarm switch is in the OUT position the alarm
will sound if the gas flow stops. When the red light is ON, gas is not flowing through the
system.
10.A supply – exhaust cross connect valve – allows gas to flow directly from the supply
to the exhaust side of the system during initial pressurisation or when changing gas
mixes.
