Changing a Container
NOTES:
• The level of material in a container is shown only on the PICO controller display.
• Container size and limit values are entered via SD card or fieldbus.
• The PICO controller calculates the amount of material remaining in the container by using the container size and
the amount of material dispensed. Because the dispensing amount is identified empirically per line, this calculated
value may deviate from the actual amount of material remaining in the container.
• Frequently shutting off the PICO controller can lead to a false remaining amount indication. This is because the
remaining amount is continually calculated according to the parameterized amount per line in real-time and the
calculated remaining amount in the EEPROM is only secured cyclically in intervals of 10 minutes.
To replace a container at any time with an equally sized full container:
1. From the Main Menu, select Process Data > Level Control > Valve X > Container > Change Container.
2. Press the Enter key to confirm container changeout (the dispensing process stops, but the current line will be
completed).
3. Change the container.
4. Press the Enter key to confirm (execute) container changeout.
The PICO controller assumes the full amount in the container as the remaining amount and updates the values
shown on the Level Control screen. If the size of the new container is different, enter the new container size via SD
card or fieldbus).
5. Restart the dispensing process in accordance with the production line specifications.
To replace a container when a Limit Reached or Container Empty screen appears:
1. Check the actual amount of material remaining in the container.
2. Based on the amount remaining, choose one of the following options:
• To change the container—Perform the steps under “To replace a container at any
time with an equally sized full container:” on page 46. The controller resets the
Remaining amount to the value of the full container size.
• To continue dispensing without changing the container—press ESC and continue
dispensing until the container is actually empty. If the calculated residual value =
zero, the Container Empty screen appears.
NOTES:
• The dispensing process is not automatically interrupted. A new signal is not sent to
the PLC. Make sure to check the remaining amount of material and replace the container in a timely manner.
• When a Limit Reach or Container Empty screen appears, the dispensing process is not interrupted. The
controlling PLC receives the OUT_FAULT_PLC status signal from the PICO controller.
