Item Description
Switch Point (if in Auto Mode only)
Switch Point is set at a percentage of line speed. In the example shown above, 10%L equals
10% of line speed. Below the Switch Point speed, the system runs in pressure control mode
4 (PID control, in order to maintain the pressure set point). Above the Switch Point speed, the
system runs in normal line speed following mode (utilizing the auto min and auto max
parameters).
The switch point value is displayed as programmed. Press the input field to edit the value.
Manual Setpoint (if in Manual Mode only)
5 The manual setpoint RPM of the pump is displayed as programmed.
Press the input field to edit the value.
6 Press the arrow icon to go to the previous pump screen (ie, Pump 1, etc.).
Set the pump to the desired mode by pressing either MANUAL, OFF (STOP) or AUTO.
• MANUAL: The pump speed is adjusted manually by the operator. If MANUAL is selected
the icon is highlighted green.
• OFF (STOP): The pump is stopped, until AUTO or MANUAL is selected. If OFF is selected
the icon is highlighted red.
• AUTO: The pump speed is controlled via a 0–10VDC signal that is provided by an external
device (pattern control equipment or parent machine input). If AUTO is selected the icon is
highlighted green.

A minimum speed is necessary to keep the pump turning in order to maintain a minimum
amount of adhesive pressure through the hose and applicator head.
For instance, if the input signal is 10VDC at 100 meters per minute and the pump
percentage of full speed is 100% (maximum speed), but the system is putting out too much
adhesive, adjusting the MAX pump percentage to 50 will cause the pump to slow down over
the parent machine's entire speed range and adhesive output will be decreased.
Settings Button
Press this button to go to the Extended Pump Mode Settings screen where you can select the
8
Current Pump Mode "Linear Line Speed" or "Pressure Control" and you can go to the
"Automatic Ramp Compensation" screen.
9 Press the arrow icon to go to the next pump screen (ie, Pump 3, etc.).
BACK Button
10
Press to return to the previous screen.
LINE SPEED: The actual (or calculated) line speed is displayed.
11
PRESSURE: The actual pressures are displayed.
The primary pressure input can be controlled via the Pressure Set Point (point 3) set on this
12 screen.
The secondary pressure input is just a readout function.
See explanation under Main Screen point 4.
SPEED: The actual (or calculated) pump speed is displayed.
