Open Dispense Valve (ODV) Setting (C3)

The next step in the calibration process is to determine the proper position to open the Dispense Valve (DV) during the shot.

Advancing or increasing the opening position (in millimeters) will build more pressure in the material hoses prior to the dispense valve opening. If the Dispense Valve opens too late in the shot, a surge of material can occur or the piston could stall. If the Dispense Valve opens to early in the shot, material “drooling” at the beginning of the dispense cycle could occur.

Hibernate and Demo Modes

Miscellaneous Machine Features

HMI Hibernate Mode

To help preserve the life of the HMI backlight, the HMI will enter a Hibernate mode after the machine has remained idle for an extended period of time. To exit Hibernate mode, the user simply needs to activate a HMI key or the machine footswitch.

When in Hibernate mode, the HMI LCD backlight

will be turned OFF, and the enter LED will blink at a slow duty cycle (1 part ON, 8 parts OFF).

If the machine performs a purge shot when the HMI is hibernating, the HMI will remain in Hibernate mode.

HMI Startup Animation Sequence

When power is applied to the machine, the

electronics need time to initialize communication. An “Hour Glass” animation sequence is generated

(

, , , , , ….). Attempts to use the

machine during the startup period will be rejected.

HMI Demo Mode Operation

The machine HMI is equipped with a demonstration mode. When in “Demo Mode”, the HMI will not send any requests to the Fluid Control Module and the machine will not operate. The HMI will simulate normal operation and provide audio feedback to the user. All Demo Mode Maintenance and Calibration screens are identical to screens provided in normal mode operation.

Demo Mode can be used as a training tool for the

user. The user simply has to connect the HMI unit to a separate power supply module, and the HMI will operate normally without the machine attached.

Any calibration, passwords, shot sizes, purge timer

settings, or other miscellaneous settings entered while operating in Demo mode WILL NOT alter any normal mode settings. Also, the first time Demo mode is entered, all the calibration & maintenance screen setups previously described will need to be repeated.

If the press and hold does not start immediately after the animation sequence, or the press and hold is interrupted, the previous and this step may need to be repeated.

4. After 6 seconds, the HMI will generate a single tone and the Demo Mode ON or OFF state will be changed.

5. When in Demo Mode, a “D” will remain on the bottom left-hand corner of the Run screen, as indicated in the following figure.

Figure 33: Typical Run Screen in Demo Mode

6. To switch the HMI out of Demo Mode, repeat the previous steps.

Limitations of Demo Mode Simulation

Even though Demo Mode provides a good training simulation for the user, it does have limitations when compared to the HMI operating in normal mode.

• On the Run screen, all the shot mode shots are simulated as single piston stroke shots regardless of the shot size and calibration numbers entered.

• The run screen animation sequence of the piston movement is not as gradual as in real operation.

• On the Run screen, during Operator mode operation, a stalled piston condition is not simulated.

• The piston cycle counter is not stored for use after power interruption, so if power is cycled to the HMI, the cycle count will be reset.

• The piston position numbers provided on the C1 screen are simulated.

To configure the HMI into and out of Demo Mode:

1. Temporarily remove power to the HMI.

2. Re-apply power to the HMI.

3. Immediately after the completion of the startup

sequence ( hold the first soft key for at least 6 seconds.

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.

E12 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.

E13 The Run Token in the FCM is missing (not installed), or does not have the

correct data.

E21 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.

E23 User has requested a shot < the minimum allowable size entered during

calibration. (< 15% of stoke, N/A in Operator Mode).

E24 The calibration done on the machine is invalid, so the requested shot cannot

be executed. For instance, a Large Stroke Calibration Shot mass which is less than the Short Stroke Calibration Shot mass (C4 screen) will create this error code. If the wiring to the linear position transducer is reversed this error will appear. If invalid piston positions are calibrated into the machine (C1 screen) this error will appear.

E25 The piston velocity is slower than the calibration velocity measured, by the

percentage amount selected by the user (20%, 40% or 60%). If the user selects 0%, this monitoring or alarm feature is disabled.

Delta Velocity (“V”) Plus Error

Low Material Level, Tank A Alarm or Error

Low Material Level, Tank B Alarm or Error

If generated, shot size accuracy may be degraded. Typically the problem is created when the machine pressure regulator is adjusted to different value from when the machine was calibrated. Another less likely cause could be a mechanical failure with dispensing (worn piston, etc.). This error will not be generated for a purge shot or when the machine is in Operator mode.

E26 The piston velocity is faster than the calibration velocity measured, by the

percentage amount selected by the user (20%, 40% or 60%). If the user selects 0%, this monitoring or alarm feature is disabled.

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 re-assemble. Lubricate all parts with a thin coat of approved lubricant, or silicon oil.

• 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 re-programmed, re-insert the blue run token in the slot provided.

9. If programming a second electronic module, repeat steps 5 through 8.

10. Re-apply machine power.

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.

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.

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 re-installed at the end of the re-programming procedure.

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.
