Press the ‘LEARN’ key, or wait for the time out to enter the new setting. The tubing diameter will now
be set to the new setting. The new diameter will be used as the current calibration setting and override any
previously entered calibration volumes.
10.14 Set Dispense Mode
When selected, the dispense mode setting is displayed:
n
, where ‘n’ is the
setting: ‘0’ = Disabled, ‘1’ = Enabled.
When enabled, the pump will be in Dispense Mode. Also, “Program Mode Lockout” will also be enabled
or disabled.
10.15 Set Program Mode Lockout
When selected, the “Program Mode Lockout” setting is displayed:
n
, where ‘n’ is
the setting: ‘0’ = Disabled, ‘1’ = Enabled.
When enabled, the user will not be able to enter Pumping Program edit mode unless the pump is already
programmed with a multi-phase pumping program.
10.16 Exit special setup menu
When selected, the special setup menu will be exited.
11. Pumping Program
A Pumping Program is simply a pre-defined sequence of actions, or functions, which guarantees
consistent and precise operation of the pump, automatically, and with or without any user intervention. A
Pumping Program can be as simple as continuous pumping at a fixed dispense rate. Or a Pumping
Programs could consist of a pumping rate and direction of pumping for a specified volume, then switch to
another pumping rate. Also a Program can interact with external devices through the TTL I/O connector,
make decisions, or stop pumping for a period of time.
Programs are broken into individual operations called Phases. Each Phase consists of a function that can
be a control function or pumping function. A pumping function, such as ‘RATE’, consists of a pumping
rate, optional “Volume to be Dispensed”, and the pumping direction.
Complex dispensing systems can be designed, involving multiple liquids, each dispensed from a different
pump, plus other equipment and sensors. Pumping Programs can be designed for each pump which
enables multiple pumps to synchronize with each other, and the other equipment and sensors, using a
cable connected to the TTL I/O connectors of each pump.
When the Pumping Program is started, either from the keypad, TTL I/O connector, or from RS-232, the
Pumping Program will begin with Phase 1 of the Program. After the completion of each Phase, the pump
will immediately start the next consecutive Phase. This linear sequence of Phases can be altered by
certain functions that direct the Pumping Program to continue operation with a different Phase number.
Some functions can change the order of operation conditionally based on external events.
11.1 How to Enter Pumping Programs
Note: Dispense Mode needs to be off to enter a Pumping Program. Start by organizing your pumping
requirements into specific actions and conditions that can then be programmed into Phases. For more
advance programming methods, common groups of Phases can be grouped together and repeated multiple
times using looping and jump functions.
The current values of the pumping rate, optional “Volume to be Dispensed”, and pumping direction, all
refer to the currently selected Phase. To display or change the currently selected Phase, enter “Program
