HMI Display Operation and Identification
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 at the preset volume and flow rate. For
the preset style, see Setup Screen 2 - Shot,
page 29.
• Bead mode: Per the style selected, the system will
dispense at the preset flow rate. For the preset
style, see Setup Screen 3 - Bead, page 29.
• Sequence mode: When the system works in
automatic status, the Customer Control Box (N) can
send 'dispense' signal to initiate t he sequence. The
working sequence can only be edited before
dispense starts. The sequence includes 14 steps
maximum.
- 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: For enabling sequence mode, see 'Enabling
sequence mode' in Advanced Setup Screen - 2,
page 35. For preset sequence style, see Setup Screen
4 - Sequence, page 30.
