Features & Controls: Front Panel (continued)
Deposit Volume / Forward
In PROGRAMMED DISPENSE mode, press the Forward button to activate the Deposit Volume screen. Use the
(+) or (-) buttons to change the deposit volume as needed.
Deposit volume, measured in cc’s, is automatically linked to Forward steps in the Ultimus IV stepper motor. When
you increase the cc setting, it automatically increases the number of Forward steps. The maximum number of
Forward steps is 65,534.
Deposit Volume is displayed when you press the F3 / Shot Volume button.
In MANUAL mode, pressing and holding the Forward button will extend the plunger from the cable assembly.
Pause
The Pause function “pauses” the action of the plunger during a dispense cycle, acts as a settling period, and
allows the relief of back pressure between Forward and Pullback steps. Pause is helpful when you are dispensing a
large amount of material with a very small tip. In most cases you will not need to use the Pause function.
In PROGRAMMED DISPENSE mode, press the Pause button to insert an end-of-cycle pause. Use the (+) or (-)
buttons to set the Pause time.
In MANUAL mode, the Pause button is not active.
• Pause is measured in milliseconds. The maximum Pause is 60,000 ms (one minute).
• The default setting for Pause is 0 ms.
