5.3. Resin gel alarm (RGA) – Flush machine!
If during an injection, the pumps do not move a complete stroke in the time specified
in resin alarms configuration screen (see section 4.4), this alarm is generated. This
alarm is designed to prevent the user accidentally allowing resin to gel in the mixing
head, and indicates the pumps have stalled during an injection.
To clear the alarm either flush the machine or adjust machine settings to make the
pumps start pumping once again.
5.4. Autosprue 1 position error
This alarm is produced if a sprue is enabled with limit switch monitoring, but fails to
report the correct position during an injection. To clear the alarm the fault must be
corrected. See Table 5.0 for a list of possible problems and suggested actions to
provide a solution.
This alarm will prevent the operator from starting the machine and stops the machine.
Problem Suggested solution
Sprue mechanically prevented from
moving between open/closed states Service auto sprue
Sprue does not change position Ensure air line is correctly connected
Sprue moves correctly Are electrical connections connected
correctly/wiring fault
No limit switches in use Disable limit switch monitoring

5.8. Motor comms error
This alarm is displayed if the motors fail to respond to a communications request from
the PLC. If this error occurs, it implies that an equipment failure has occurred and a
suitably trained maintenance technician should be informed.
Acknowledge the fault to clear it.
5.9. Motor fault
This is a general motor fault condition. Ensure the e-stop button is not activated and
safety circuit has been reset. Powering the machine down and then restarting after
waiting for 60 seconds can be tried, if the alarm persists.
