Troubleshooting
Should the pump fail to operate, make the following checks to determine whether or not
servicing is required.
Check that the power switch is on.
Check the mains supply is available at the pump.
Check the voltage selector switch is in the correct position.
Check the fuse in the mains socket.
Check that the pump is not stalled by incorrect fitting of tubing.
User interfacing
When powering-up the pump the user will be taken into the main menu.
Use the Step key to move between menu options. Use the Enter key to confirm settings.
Use the number keys to enter in settings. Use the Up or Down key to increase or decrease
set values in the pump software i.e. ramp settings, date, rpm etc.
Dose permits the set-up of dose programs for dispensing. A dose can be initiated by using
the Start button or external switching. The pump will allow up to 26 dosing programs to be
stored and recalled at any time. A printer can be connected to the pump for recording of
dispense runs. Batch and operator codes must be entered when using a printer.
Cal allows the pump to be calibrated for accurate dosing.
Manual allows continuous transfer/fluid metering via keypad control.
Auto enables analogue or RS232 control.
Setup displays and controls the user and factory settings for the correct operation of the
pump.
The speed/volume flow rate of the drive is governed by the pumphead and tubing selected.
Dosing procedure
The Dosing program is outlined in the technical data section of the operating instruction in
a flow chart format. Each step in the procedure is described to provide full understanding of
the procedure.
Within the technical data section are mean values for dose time guidelines and accuracy
figures recorded using Silicone tubing at zero suction and pressure. For the highest
accuracy use small-bore tubing and maximum roller passes. Always use a calibration dose
to ensure the highest accuracy possible.
