KDS Programmable Pumps General Information KEYPAD PROGRAMMABLE PUMPS The "program mode " is available on all Series 200 models and permits multistep dispenses without the need for computer control.
KDS Programmable Pumps Features PARAMETERS WHICH CAN BE PROGRAMMED IN EACH STEP Time duration Infuse or withdraw Start flowrate End flowrate TTL output settings Pause, wait for TTL input actuation Loops to repeat previous steps To simplify the programming, previously programmed settings are stored in non-volatile memory and are displayed when Program Mode is selected. Whenever possible, options are displayed with the "active" option flashing. If flashing, this parameter can be selected or changed.
KDS Programmable Pumps Menu Operation After selecting MODE and then PROGRAM the display will show STEP which leads into editing the program. 1) Number of STEPS Menu prompts " NUM of Steps". Enter total number of program steps using numerical keypad and press SELECT or ENTER to save a maximum of 8. 2) Edit STEP # The menu automatically increments the step number, however, it is possible to enter a different number.
KDS Programmable Pumps Menu Operation (Continued) 5) 6) Rate (Continued) c) Options: 1) if R1=R2=0 The pump is stopped, no flowrate. 2) if R1R2 Flowrate decreases LINEARLY from R1 to R2 over the step time. PIN OUT TTL Output pins can be controlled to set the levels high (H) or low (L) during the step. This change in status of an output pin can be used to trigger another external event.
KDS Programmable Pumps Menu Operation (Continued) 8) Loop (Continued) b) LOOP COUNT After setting the initial step number of the loop, the menu will prompt for the "loop count", the number of times the loop will be repeated. Maximum repeat number is 100. Display reads: # Loop Count: x The number of loops to be executed, x is entered from the numerical keypad followed by ENTER. Note: a) 9) Maximum number of loops is two. Once both loops are entered the loop option will NOT be displayed in menu.
KDS Programmable Pumps Running The Program Run The Run key starts the program; the displayed time counts down and the direction arrow flashes. Hold/Continue If the Run/Stop key is pressed while running a program, the pump is stopped but gives an option to end the program, or restart the pump and continue the program to its end. Program changes when operating Once a step has commenced no changes are possible in that step. However, while dispensing changes are permitted to steps still to be executed.
KDS Programmable Pumps RS232 Commands and Responses All commands and responses in standard pumps remain the same, however, the program mode does have additional commands and responses. Each pump can be controlled either from the keypad or via RS232 at all times, but the pump can only respond to one command at a time. When under RS232 control the display reads "REMOTE". All settings made via RS232 are stored in non-volatile memory. To move the pump from Remote (RS232) to keypad control press select.
