Error Codes (Standard Display Module) - Graco PR70 Repair And Parts Manual

Error Codes
(Standard Display Module)
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 dis-
played 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 dis-
abled.
When errors are generated, the machine will automati-
cally 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 sus-
pended, 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:

Cause, Details
A key on membrane has been active (pressed) for > 30 seconds
continuously. Replace the HMI. This error code does not require user
acknowledgment and will clear itself automatically if the condition is
removed.
The Display module has lost communication with the Fluid Control Module.
Material dispensing will be disabled if this condition exists. Check
communication cables between the 2 electronic components, or check the
HMI and/or the Fluid Control Module.
This error will be regenerated continuously while the condition exists.
The Run Token in the FCM is missing (not installed), or does not have the
correct data.
A piston stroke action has taken > 55 seconds. Typically caused by no/too
little air pressure to the machine or a mechanical interference with the
piston has occurred. Check machine input line pressure.

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

hand corner of the Run screen, while the condition is still
present.
F . 2: Typical Run Screen with Active Error Code
IG
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 num-
ber 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.
