Span Your Valves
Chapter 9
9-9
Span your clamp close pressure valve(s) for optimum performance. Do
this in four parts:
Confirm critical values
Span your clamp close pressure valve(s)
Test valve linearity
Set pressure alarm setpoints
Important: You may omit the next three parts of this section if you have
the right information on valve spanning. Many injection molding machine
OEMs and hydraulic valve manufacturers provide data on spanning the
working range of valves used on their machines. If this information is
available from your OEM for your machine’s clamp close pressure
valve(s), enter the values into pressure control limits FCC41-44,
SCC41-44, and TCC41-44 and proceed to Set Profile Pressure Alarms.
Confirm Critical Values
Important: Confirm that your entries for configuration values (chapter 7)
and profile values (chapter 8) for clamp close profiles are as follows:
