•
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.
•
Check that the keypad lock is not switched on.
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
Ù or Ú key to increase or decrease set values in the pump software i.e. ramp settings, date, rpm
etc.
Dose permits the set-up of doses 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.
Network enables RS232 control
Set-up 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. Factory default is for a 501RL
using 8.0mm bore tubing which means the max rpm/volume flow rate of the pump is 300 rpm/3000ml/min.
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.
Print audit routines
If a printer is connected, the completion of a dose run will automatically call the print routine. The first request will be to
enter the operator ID.
Up to 16 characters can be entered. Digits and the decimal point are entered directly from the keypad. Alpha characters
are entered by pressing
Ù or Ú which call A to Z and Z to A respectively in circular rotation.
An alpha character is embedded by pressing Step. A numeric character is entered by pressing Step , any other numeric
character, the decimal point or
Ù or Ú.
On pressing Enter, the pump will request the input of a batch number.
Again, up to 16 characters can be entered as for the operator identity. When Enter is again pressed, the following
information is printed out: date, time, dose size, specific gravity, dose interval, number of doses, initial ml/rev,
recalibration data, operator identity, batch number and number of doses delivered.
Following the print out a repeat dose option will be given.
Single dose command
Single doses can be dispensed on demand, with a count of the number of doses being kept.
Set the interval time to 0 SECONDS and the number of doses to 1.
To start single dosing, press Start or use an external start dose switch. The display will indicate the total number of
completed doses up to a maximum of 99,999 after which the counter will restart at 0, so that dose 100,001 would be
shown as 1.
Calibration procedure
Calibration of the 505Di is based on informing the pump under Cal of the pumphead and tubing which are to be used.
Alternatively a calibration dose can be used. The calibration dose will run for a maximum of 4 minutes, but can be
stopped at any time up to 4 minutes. The longer the calibration dose the more accurate the calibration. Entering into the
pump the physical volume (ml) or mass (sg) to complete the procedure and will allow the pump to take into account
ambient conditions and also the viscosity of the fluid.
Manual operation
•
Switch power on (drive rear panel).
•
Change the set speed by pressing the Ù or Ú key. The minimum speeds of the 220rpm and 350rpm drives are 1rpm
and 2 rpm respectively.
