  • Page 18: Screen Identification

    Screen Identification Screen Identification Main Screen This is the default screen that shows up when the machine is powered on. It shows the current state of the machine and navigates to all screens related to setup and running. Icon Description Shows the current mode of the machine.
  • Page 19 Screen Identification Icon Description Navigates to a screen allowing calibration of: • Pressure Transducers • Cylinder Linear Position Sensor Navigates to a screen allowing the user to select if a condition is either a Warning (keeps the machine running) or a Fault (stops dispensing). Navigates to a screen showing the history of alarms that have occurred.
  • Page 20 Screen Identification Mode Select Screen The Mode Select Screen is used for the following: • Select the mode to operate the machine in. • Turn color injectors on or off. • Enable/Disable Frequency Fault Alarms. Icon Description This mode allows the machine to operate in a fully automatic mode. It waits for a signal from the press to begin dispensing material.
  • Page 21 Screen Identification Icon Description “Outlets Closed” is the default state. It allows the button to open during a “Manual Feed”. Toggling the button to “Outlets Open” keeps the outlet valve open at all times - even during a refill. The unit will refill the pump cylinders while this button is pressed. Letting go of the button mid-refill will cause the machine to stop refilling.
  • Page 22 Screen Identification Monitor Screen The Monitor Screen shows the vitals of the system at a glance. It indicates how much material remains in the pump and what pressures are in the system. If color injection is enabled, it shows the injection interval and when the next injection will occur.
  • Page 23 Screen Identification Alarm History Screen Shows a history of the alarms generated by the unit. System IO Screen Shows what inputs and outputs are active on the unit. 332078C...
  • Page 24 Screen Identification Calibration Screen The calibration screen allows the user to adjust any sensor on the system that appears to be out of calibration. The top half of the screen is for pressure transducers and the bottom half is for the position sensor of the pump. Icon Description Configuring pressure transducers on the unit.
  • Page 25 Screen Identification Presets Screen Screen 1 Icon Description The total shot volume of the 633 machine is 150 cc’s. The value in this field indicates how much material is required to fill the mold in the press. If there is not enough material left in the cylinders to fill the mold, the machine will trigger a refill.
  • Page 26 Screen Identification Screen 2 Icon Description Minimum pressure must be present on both the A and B cylinders during refill. The cylinders will stop refilling until the pressure rises above this set point. Amount of pressure that is supplied to the pump to assist in refill. It may cause the material to dip below the “A - B Min Refill Pressure”...
  • Page 27 Screen Identification Screen 4 Icon Description Both material pressures are being monitored during the refill and dispense cycles of the machine. If the one component material pressure drops below the other component material pressure by X amount, the machine will alert the user. This is the amount of time before the alarm is checked after the refill done bit activates.
  • Page 28 Screen Identification Alarm Setting Screen Icon Description Conditions listed above can be configured as a “Warning” or a “Fault” condition by User #4 (Refer to Select User Level Screen, page 29). Touching the “Warning”/”Fault” text will tog- gle the condition. A “Warning”...

  • Page 31 Screen Identification Warning and Alarms Screens Refer to the Calibration section of the manual for details on calibrating the pressure transducers and the position sen- sor of the pump. If equipped with a material level sensor on the color reservoir, the warning will indicate that the material level is low. If the warning has never been generated before the machine runs out of colorant, the low level sensor may need to be recalibrated.
  • Page 32 Screen Identification These screens indicate that the machine was not able to refill its plungers properly. The likely cause for this is the feed system was not able to provide material. It is detected by monitoring the pressure in each cylinder during a refill. If installed, refer to the SR657-1M-LR Meter-Mix Dispense Systems-Operation manual for additional details.
  • Page 33 Screen Identification This indicates that the unit could not fill its plungers completely. Verify the following: • Verify the feed system is functioning and providing enough pressure. If installed, refer to the SR657-1M-LR Meter-Mix Dispense Systems-Operation manual for additional details. •...
  • Page 34 Screen Identification The feed station has indicated that it requires attention. This indicates that it may no longer be able to supply material to the metering unit. Refer to the feed station manual and check if there is sufficient material in it. These warnings indicate that the combination of the shot size and the injection percent will result in inconsistent mix- ture in the material.

    * Flow rates and viscosities are general estimates. Flow rates drop as viscosity increases. Fluids are expected to shear under pressure. New applications or fluids should always be tested to determine proper line sizes and equipment selections. See your Graco authorized distributor for other capabilities.
