The RGA alarm whistle volume can be changed by adjusting the flow controller
that is in line with the whistle.

Guard Interlocks – CE Units only – If the machine is fitted with a slave arm
guard that does not require a tool to open, the guard will be fitted with an
interlock to stop the pump running when it is opened.
In this case, if the guard is open, or not correctly closed, the machine will not
operate in injection, prime or recirculation modes. Opening the guard while the
pump is operating will have the same effect as pressing the stop button.
Catalyst Over-Pressure protection – The machine features catalyst
overpressure protection. In addition to the industry standard inclusion of a
pressure relief valve in the catalyst circuit, the control circuit will detect the over-
pressure condition and stop the pump from running. In injection, prime or
recirculation modes, this is equivalent to pressing the stop button.
For example, if during an injection the catalyst system is over-pressurized, the
injection will stop, the injection gun will close and the TAS signal will exhaust.
A visual indicator is provided on the side of the control box (see figure 8), which
will change from black to red in the event of a catalyst over-pressure condition.
To reset the over-pressure control circuit, the catalyst pressure must be relieved
and the reason for the condition must be remedied before the machine can be
operated in injection or recirculation modes.
