5.5 Pressure Sensor Calibration
The pressure sensors are offered as optional accessories to measure the material
pressure differential between the two pumps. When the mixing nozzle is restricted
and started to clog, the material will flow upstream, causing cross-contamination.
When this event occurred, the material pressure differential will increase significantly.
The pressure sensors will send the signal to the controller shut down to pump.
Preparation
NOTE:
In order for pressure sensing to be operational, the Max. Pressure Differential
setting must be non-zero. Please refer to Section 5.10.
•
Ensure the Pressure Differential value is set to a non-zero value.
•
External pressure sensors should be attached to the pumps and connected to the
rear panel.
•
The pumps should be prepared to dispense as desired (Rate and Ratio).
•
Purge Mode should be selected.
1.
From the calibration select screen, click on
. You will
see the External Pressure Calibration Screen.
2.
Press the
button to clear any existing calibrations.
3.
Press and hold the Footswitch or close the contact closure on the rear panel or
apply 5-24V on the rear panel input. Do this for approximately 3 seconds. You
should see numbers update on the front panel.
4.
While dispensing, press the
button.
