OPERATING INSTRUCTIONS
RM350 GAS CONTROLLERS AUG 15 2 of 13
Please read the following information carefully before installing and using the equipment.
Compressed air and gases can be EXTREMELY dangerous and MUST be treated with extreme
care. This equipment works at pressures up to 620 Bar (8990 psi) and uses single and 3 phase
electrical power (certain models).
REMEMBER: Nitrogen gas is an asphixiant. Never breathe in gas escaping from the system. Nitrogen
gas is not poisonous, but can overcome a person in a confined space. Always stay alert when venting
Nitrogen gas.
REMEMBER: don’t be fooled by the size of the high-pressure receiver. A 50-litre receiver charged to
350 Bar contains the equivalent of 17500 liters of gas at atmospheric pressure.
REMEMBER: unlike hydraulic oil, gas is compressible, and will continue to expand until the pressures
inside and outside the system equalise.
NEVER commence any maintenance or servicing work on the equipment without ensuring that the
system is depressurised.
NEVER adjust a pipefitting that is under pressure.
NEVER adjust a safety valve to achieve a lifting pressure higher than that set at the Maximator factory.
Asafety valve is provided to prevent over pressurisation of the system and overloading of the
compressor. Tampering with a safety valve can cause serious damage or injury.
NEVER run the equipment without the guards it was supplied with.
NEVER re-use damaged fittings, especially if they rely on threads for security (i.e. pipe fittings, nuts,
bolts, etc).
NEVER attempt to straighten badly bent pipes
NEVER allow any part of your body or any person to be in front of an opening that is venting gas.
Particles from inside the system can become embedded in the skin and cause serious injury or death.
ALWAYS take care when opening valves or venting the system, and open the valve
slowly. ALWAYS isolate the electric power supply before commencing work on the system.
ALWAYS entrust electrical work to a qualified electrician.
ALWAYS comply with local, regional and national legislation.
REMEMBER:
COMPRESSED GAS AND ELECTRICITY CAN KILL.
TREAT THEM WITH RESPECT.

The gas controller controls gas each cycle according to settings in the cycle settings panel. The cycle
starts from the gas start signal. A delay is available, followed by 5 phases of pressure control according
to the the model below:

Purge and clean function
4. Clean settings panel
The Clean (purge) function sets an output pressure for a valve. It is normally used to test the flow from a
gin pin, or to provide a short blast to blow accumulated dirt and contamination from the gas pins.
Clean function can be oprated manually by touching the “purge” button, or automatically.
Whether manual or automatic, the pressure is set in the clean settings panel.
Automatic clean periodically operates the clean function after the gas cycle has finished and the mould
closed signal is lost (to allow venting through the gas pins while the mould is open)
1
The number of cycles between automatic clean operations
2
Clean pressure
3
The time from the opening of the mould to the start of the automatic clean operation
4
The time that the pressure is set for the automatic clean operation.
5. Start signal select
There are two signals in each interface that can be used to start a gas cycle. If this function is enabled,
you will be able to select start signal A or B for this valve.
6. Monitoring panel
Cycle counter: displays the number of completed cycles. Touch to reset the counter
Preset and actual pressure settings are shown for the current pressure control phase
7. Select valve and purge controls
OFF
This valve is turned off and will not run
IF1
This valve is connected to interface 1 and will start when the unit is in
automatic mode and a start signal is received at interface 1
IF2
This valve is connected to interface 2 and will start when the unit is in
automatic mode and a start signal is received at interface 2
Purge
Touch to purge from this valve at the set clean pressure.

1
Valve alarm limit - %. When running a cycle, if the machine cannot achieve
the preset pressure to within this percentage, for the time set in [2], then a
“Valve Vx” pressure alarm will be displayed on the status valve for the
affected valve. The affected valve cycle will be ended. The machine will
continue to run, and the machine will continue to attempt to cycle the affected
valve.
