Duo System setup & initial settings

Please reference the following information for basic Duo System setup. For more information, consult the Duo System User Manual.

Priming the system

To prime the system, set the count to 1 and the duration to 0.25 for each roller. To dispense fluid to the rollers by rotating the rollers with scrap material or cardboard allowing the fluid to saturate the roller around the whole circumference. If the rollers become over saturated, fluid will pool up on the stock material and can cause issues downstream.

Fluid settings

It is best to adjust the duration (DuR) rather than the count (cnt). A small change in the count can have a substantial effect on the output. For example, if the count was originally set at 2, increasing it to 3 will decrease the dispensed volume by 33%. Decreasing count to 1 will result in doubling the dispensed volume. By adjusting duration in proportion to the desired change in dispense volume, it is possible to make small changes. It is always better to make small adjustments to roller outputs and allow time to see the effect rather than making large changes right away.

Changes to fluid settings

These fluid settings should be a good starting point for your job. In order to get the desired amount of lubrication, these values may need to be changed. When changing these values do small incremental changes to the settings and allow time to see the affect on the applied lubrication.
