Progress bar and dispense volume
• Progress bar
-
Shot mode: The progress bar displays the
completion of the current target.
- Bead mode: the progress bar always displays
100%.
• Dispense volume: There are two dispense volume
values. The left is the volume for current dispense,
and the right is the current job’s accumulative
volume.
Control mode
Automatic mode includes three control modes: shot
mode, bead mode and sequence mode.
• Shot mode: Per the style selected, the system will
dispense a shot at the volume of flow rate preset in
the style selected.
• Bead mode: The system according to the selected
style will complete the dispensing at the preset flow
rate.
• Sequence mode: When the system works in
automatic status, the Customer Control Box (N) can
send ‘dispense’ signal to initiate the sequence. The
working sequence can only be edited before
dispense starts. (The sequence includes 16 steps
maximum, and the operator can edit step 1 to 14, as
step 0 and 15 are reserved respectively for
pre-charge and depressurization).
-
When ‘Enable Sequence Mode’ option is not
selected and the system is not dispensing, the
operator may choose between ‘Bead’ or ‘Shot’
mode by using the touch screen or customer
signal.
- When ‘Enable Sequence Mode’ option is
selected, control mode will be fixed as
‘Sequence’ mode. ‘Bead’ or ‘Shot’ mode will be
inaccessible.
NOTE: ‘Enable Sequence Mode’ option is in screen 3 of
Advanced setup. See Advanced Setup Screen 3 on
page 39.
