2. Calibrate HFR
The HFR calibration procedure is a two step process.
The first step, Learn Mode, must be performed when-
ever the pump line is rebuilt or if any other maintenance
is performed that may affect the mechanical tolerances
in the pump line. If the machine does not appear to be
utilizing the full extent of the pump stroke, or if the
machine appears to be contacting the end of the
hydraulic cylinder, follow the Learn Mode procedure.
The Learn Mode procedure will teach the system the
mechanical limits of travel.
Learn Mode Procedure:
a. Navigate to the Calibration screen.
b. Press the Learn Mode Calibration button
and set the mode to run as the dispense appli-
cator that is installed on the system.
NOTE: For circulation systems, set the mode as either
EP or MD2 valves. These settings will not dispense
material.
c. Place a waste container below the dispense
valve. The next steps will cause the machine to
dispense material for all other settings.
d. Press the go right button and then the dis-
pense button . The pump will travel to the
right most extreme position.
e. After the pump stops moving, press the go left
button and then press the dispense
button . The pump will travel to the left most
extreme position.
f. After the pump stops moving, press the con-
tinue button to go on to the next step in the
calibration process or the page back button
to return to the main Calibration screen.
NOTE: During this process, the system learned the
mechanical limits of travel. If the pump did not reach
both the left and right extreme limits for any reason,
repeat the procedure.
If the system is to be used in a Time or Volume Dis-
pense Mode, system calibration is complete after the
Learn Mode procedure described above. However, if the
system is to be used in Weight Dispense mode and the
application requires that the dispense amount be accu-
rate and consistent then the weight calibration proce-
dure below must be followed.
