2 Main Air "On/Off" Valve/Pressure Regulator/
Pressure Gauge/Filter
Figure 3-3
This set of pneumatic components controls,
regulates and filters plant air supply to the
pneumatic circuit of the case sealer.
"On/Off" Valve
"On" turn to "SUP" "Off"
turn to "EXH".
Note Turning air supply
"Off" automatically bleeds air pressure from
the case sealer air circuits.
Always turn the air "Off" when machine is not in
use, when servicing the machine, or when
connecting or disconnecting air supply line.
Note
The air valve has provisions for lockout/
tagout according to plant regulations.
Pressure Regulator
regulates main air
pressure to the machine. To adjust pressure,
pull knob up and turn. Push down to lock
setting.
Pressure Gauge
indicates main air regulator
pressure setting. Air regulator should be
adjusted so gauge reads 6.2 bar [90 psig].
Filter
removes dirt and moisture from plant air
before it enters the case sealer pneumatic
circuits. If water collects in bottom of bowl, lift
up on the valve on the bottom of bowl to drain.
