2.5.2 Pneumatic Lockout
Pneumatic lockout of the printer is achieved by applying a padlock, or any other suitable locking
device to the pneumatic air switch. This can only be achieved when the switch is in the EXH
(Off)
position.
The pneumatic lockout switch is connected to the main air regulator at the front right hand side of
the machine, behind the front panel.
The switch positions are:
●
SUP (Supply) - On, air supply is fed to the printer
●
EXH (Exhaust) - Off, air supply is disconnected from the printer and the remaining pressure,
after the switch, is exhausted relieving the air pressure
To pneumatically lockout the printer, carry out the following procedure:
1. Ensure that electrical lockout has been completed.
2. Open the front cover.
3. Remove the front panel.
4. Turn the pneumatic switch (2) to the EXH position.
