Maintenance, Software Upgrades and Run Token
Maintenance
The following items should be checked daily, once during a shift, or as required for the application:
•Air Filter - Check air filter and release any water circuit water trapped in the base of the filter.
•Tanks – Check material levels and refill as necessary. Verify the material reservoirs are vented properly.
•Air Dryer - Check the condition of the desiccant air dryer, and replace if necessary.
•Pump Shafts – Clean both pump shafts with solvent and lubricate with approved lubricant such as mesamoll or Silicon oil.
•Dispense Head – Dismantle, clean thoroughly and
•Ratio Check – If material ratio is critical for the application, implement the ratio check procedure as required.
4.Insert a black programming token into the slot provided. Make sure it snaps into place when inserted.
5.Turn ON the AC power switch.
6.Verify the red LED on the FCM or HMI starts blinking at a fast steady rate, then the red LED stops flashing accordingly. Verify the Green LED is on continuously, and the amber LED blinks every few seconds.
7.Turn OFF the AC power switch.
8.Remove the programming token from the FCM or HMI. If the second electronic component needs updating, insert the token into the other electronic module. If the FCM was
9.If programming a second electronic module, repeat steps 5 through 8.

11.Go to the M4 screen to verify the new software revision(s).
Software Upgrades, Run Token
When software in the HMI or Fluid Control Module (FCM) needs updating, a black Graco update token is used.
Run Token
The PR70 Fluid control module (FCM) contains a blue run token, installed in the socket provided. It has identical appearance to the black programming token, but is blue.
If the token is not installed into the FCM, the machine will not operate, and an E13 error will be generated on the display module. Hence, if the FCM software is updated, it will need to be
Figure 36: Standard Graco Data Token
To transfer an updated software program from the token to the PR70 HMI or FCM:
1.Turn OFF the AC power switch in the back of the machine.
2.If updating the Fluid Control Module (FCM), open the access door to the FCM by loosening the 2 access screws. Remove the Blue Run token from the FCM.
3.If updating the Human Machine Interface (HMI), remove the HMI from the mounting bracket and remove the back cover by removing the 4 screws on the back of the enclosure.
