Shot/Flow Setup 2

Icon Description
Mixed Material Pump Pressure Setpoints (psi): For RTM applications, this box displays the current
pressure of the mixed material. The user can enter a high limit and low limit. When the machine is set
to pressure mode, the pumps cycle until the high pressure limit is reached, then the pumps stop and
the mixed material pressure drifts down below the low limit and the pumps begin to cycle again.
Current Pressure: This displays the current A and B pressure of the pump.
Low Limit Warning: This is a user settable pressure for the A and B pumps. If during pumping the low
limit pressure is not reached (due to a bad piston or leak), the low limit trips and the audible alarm
sounds. The pumps can still run during this warning. The silence alarm button turns off the alarm.
High Limit Warning: This is a user settable pressure for the A and B pumps. If during pumping the
high limit pressure is exceeded, the high limit trips and the audible alarm sounds. The pumps can still
run during this warning. The silence alarm button turns off the alarm.
