Pressure Relief and Shutdown Procedures, Error Codes
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
The following typical screen is generated when an error code is generated:

Key:
AError Code Animation Field
BError Code Number Field
DError Code ICON
EError 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.
Figure 35: Typical Run Screen with an Active 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.
