The various controls and operational modes are described in the following sub-sections.
Emergency Stop
When the E-Stop has been activated, the machine will enter a safe state. If the machine is injecting, recirculating or
flushing, the E-Stop is equivalent to pressing the stop button.
To de-activate the E-Stop, twist and pull to release.
Catalyst over-pressure protection
The machine features catalyst over-pressure 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 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 TAS/Pro gun will
close and the system will shut down.
A visual indicator (fig 4.10) is provided on the face of the control box, 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.
