2.4 Pneumatic Connection
The machine requires a compressed air supply of 5-6 Bar, which should be connected to the inlet
port of the air service set situated on the side of the machine.
2.5 Gas Connection
When the machine is operating in gas flush mode the modified atmosphere packaging gas should
be connected to the inlet port situated under the machine frame. Adjust the GTR pressure regulator
to give a gauge reading of 1 to 1.5 Bar. The gas pressure is monitored via a pressure switch. If the
value falls below a set level the guard lamp will flash and a beep sound will be heard.
2.6 Electrical Connection
The machine must be electrically connected as indicated in the machine Electrical Wiring Diagram
(Appendix A) and sized to match the requirements outlined in the Technical Specifications (Section
8).
2.7 Guarding
There is a legal obligation upon the installer to ensure the machine is in safe condition before
attempting to run.
The guard circuit is a dual channel monitoring circuit and complies with a category 3-guard circuit.
WARNING: -
On no account must Proseal machines be operated without the guarding supplied, or with any
safety device or circuit disabled or bypassed.
Before commencing operation, ensure all guarding is correctly fitted, and all guard safety interlock
switches and emergency stop switches are inspected and checked for correct operation.
All guard switches are secured using anti-tamper fasteners. Only competent qualified engineering
personnel should remove and replace guard switches using the correct tool.
