Pressure Relief and Shutdown Procedures, Error Codes
312393G 23 of 50
Pressure Relief Procedure
With the machine in an idle state:
1. If the machine pistons are not fully retracted,
retract the pistons by pressing
in the M1
screen. See Figure 17.
2. Manually open the dispense valve by pressing
the third M1 soft key until the “
” ICON is
shown in the Current DV field. See Figure 17.
3. Remove the incoming air pressure by closing the
air inlet valve (item 13 in Figure 54).
Standby/Shutdown Procedure
If the machine is to remain idle for an extended
period of time, implement the following:
1. Remove any static mixer installed at the end of
the dispense valve.
2. Place a container below the valve, and activate a
small shot to flush material away from the end of
the valve.
3. To prevent accidental pump movement, press
(red).
4. With a clean rag, clean the end of the dispense
valve to remove excess material.
5. Install a nightcap at the end of the valve.
Error Codes
When the machine is operating and a fault is
detected, it will report the condition by generating an
error code. Error codes are typically generated
when the machine is idle after dispensing a shot.
When error codes are generated, a screen will be
displayed which contains an animation sequence, the
error code number and an ICON symbol representing
the condition detected. The HMI will also output an
error code tone sequence. The tone sequence
cannot be disabled.
When errors are generated, the machine will
automatically be disabled and remain in an idle state
until the user acknowledges the condition. Any active
purge timer present prior to error code generation will
be suspended, and will need re-started by requesting
a shot after the error is acknowledged.
The following typical screen is generated when an
error code is generated:

Key:
A Error Code Animation Field
B Error Code Number Field
D Error Code ICON
E Error Code Acknowledgement ICON
When an error code is generated, the user will need
to acknowledge the condition by pressing the soft key
under the
ICON.
After the user activates the
key, the error number
generated in the Figure 34 example, will be displayed
on the bottom left hand corner of the Run screen,
while the condition is still present.

Error Code Condition
The example E12 number on the main run screen will
remain on the run screen as long as the error
condition exists. If the problem is corrected the
example E12 number will be removed.
If more than 1 error code condition exists for the
machine, the corresponding “EXX” numbers will be
listed on the bottom left corner, separated by
commas.
