deadband pressure is subtracted from the head pressure. The deadband value can be
used to provide a more stable reaction of the control system to clipping. As a general
rule, as the deadband value is reduced towards 0, the pumps will run less-smoothly.
Figure 4.5 – Head pressure clipping configuration screen
For example, if the head pressure clip value is set to 10000 mbar (10 bar) and the head
pressure clip deadband is set to 1000 mbar (1 bar); power will be removed from the
pumps if 10 bar is reached in the supply line to the mould. Power will not be re-
supplied to the pumps until the supply line pressure drops to 9 bar.
It is recommended that head pressure clipping is always enabled.
4.6. Calibration
The calibration configuration screen shown in Figure 4.6, allows the user to set the
volume of resin per stroke. This value will directly affect all volume calculations
carried out by the machine and therefore should only be adjusted with caution.
For more information regarding pump calibration, please see the relevant paragraphs
in the commissioning section of this manual.
