SP1600/1800 Programmable Syringe Pump

When the Pumping Program is started, with the ‘Start / Stop’ key, TTL I/O input, or RS-232 command,
the Pumping Program will begin operating from Phase 1.
Very complex dispensing Programs can be created with the Program functions available. Section 8.3
contains a detailed description of all the functions.
8.1.1 Pumping Program Phase Number
To set the current Program Phase number, enter “Program Entry Mode” and display the current Program
Phase number.
Using the right-most 2 arrow keys, change the selected Program Phase number. The displayed Program
Phase number now becomes the currently selected Program Phase number. All function and pumping rate
data will now refer to the currently selected Program Phase number.
If the maximum Program Phase number, 41, is exceeded while changing the Phase number, the displayed
Phase number will automatically be set to the maximum Program Phase number.
8.2 Pumping Program Edit Functions
When developing or updating a large Pumping Program, occasionally one or more Program Phases needs
to be added or removed from the Pumping Program. Having to re-enter the entire Program could certainly
be a tedious task.
Two Program entry functions are available to simplify the Program development process. These are the
‘Insert’ and ‘Delete’ functions. They allow a Program Phase to be removed from any point in the
Pumping Program or a Phase to be inserted at any point.
To access these functions, enter “Program Entry Mode” to display the Program Phase number [PH:nn].
Select the Program Phase number that is to be deleted or the Phase number where a new Phase is to be
inserted in the Pumping Program.
For example, if a Phase is to be inserted between Phases 24 and 25, select Phase 25. The inserted Phase
will be at Phase 25, and all the Phases starting with the old Phase 25 will be shifted 1 Phase higher.
Using either of the 2 left-most arrow keys, under ‘PH’ in the display, select the editing function. The
arrow keys will scroll through the selection of editing functions:
Editing Function Description
PH Phase select
In Insert Phase
dE Delete Phase
When the required editing function is displayed, press the ‘Rate’/’Program Phase #’ key before the 2
second time out. After the time out, or with any other key press, the function will be canceled.
If ‘Insert’ or ‘Delete’ was selected, the Pumping Program will be edited. While the Program is being
edited, the display will show [BUSY].
If ‘Insert’ was selected, all Phases from the selected Phase to the maximum Phase will be moved to the
next higher Phase, with the original maximum Phase being deleted. The inserted Phase will default to a
‘RATE’ function, if it is the first Phase, or a ‘STOP’ function otherwise.
If ‘Delete’ was selected, the selected Phase will be removed, and all Phases higher then the selected Phase,
up to the maximum Phase, will be moved to the next lower Phase.
All Phases that reference the Phase number of another Phase, such as a ‘jump’ function or an ‘event’
function, will be automatically updated. The referenced Phase numbers will be automatically adjusted to
compensate for the section of the Pumping Program that was shifted during the operation of the edit
function.
Ultimately, the easiest method to maintain and develop Pumping Programs is to download the Pumping
Program to the pump from an attached computer. This would allow a single Pumping Program to be
quickly programmed into multiple pumps. The computer would only need to be attached during the
download since the Pumping Program is stored in the pump’s non-volatile memory.
