15.2 Main menu entry
The MENU key displays the main menu. It operates at any point in the pump’s activ-
ity except where error screens are displayed, or screens where UP and DOWN keys
are used to enter values.
The main menu offers five options: Calibrate, Setup, Pin out details, MemoDose
and Exit. Use the UP and DOWN keys to make a choice. Press the ENTER key to
confirm your decision.
Calibrate
Calibrate allows the user to calibrate the pump with default figures for a range of
pumpheads and tubes, as well as to refine the flowrate figures with a calibration
dose facility.
Setup
Setup allows the user to set the pump’s operating parameters under 20 headings:
Trim, Analogue, Display, Pump number, Baud, Stop bits, Xon/Xoff, Flow
units, Run time, Outputs, Remote stop, Auto-restart, Set max speed,
Backlight, ROM, Language, Defaults, Beep, Security and Exit.
Pin out details
Selecting Pin out details causes the pump to display a warning screen and then its
preset pin and voltage details under 18 headings: Analogue input 1, Analogue
input 2, Analogue output, Tacho output, Direction enable, Direction input,
Run/Stop input, Leak input, Auto/Man toggle, Dose input, Output 1, Output
2, Output 3, Output 4, Supply, 0 volts, Earth and Others.
MemoDose
The MemoDose facility is used to remember the number of revolutions needed to
dispense a set volume of fluid, and cause the pump to dispense that volume repeat-
edly.
Exit
If Exit is selected, the pump returns to its last manual state with the pump stopped.
