2 PROGRAMMING THE PERISTALTIC PUMP

A short video about programming the LAMBDA Peristaltic Pumps can be found at: www.lambda-instruments.com/peristaltic-pumps/#video

Up to 99 pairs of time and speed settings (flow rates) may be programmed locally on pump display of all LAMBDA peristaltic pumps except PRECIFLOW.

The programming mode is accessed by simultaneously pressing the buttons REMOTE and RUN until the indication “PGM” appears on the display and both directions LEDs (◄|►) are illuminated.

Remark: If you repeat this simultaneous pressing of the REMOTE and RUN buttons, the memory will be cleared and the indication “cLE” will appear on the display. To enter the programming mode again, press the REMOTE and RUN buttons again until “PGM” appears.

Figure 2-1 Press the REMOTE and RUN simultaneously until indication PGM appears.
Figure 2-2 Continuous pressing of REMOTE and RUN button even after the indication of "PGM" ends up with the "cLE" indication.
Figure 2-3 Press the ON/OFF button. The indication “F01” will appear for a short time on the display indicating that you can select the first flow rate (speed setting) value.
Figure 2-4 Set the desired flow rate value for the first program step by pressing the buttons ΛΛΛ below the display (from 0 to 999, corresponding to 0 to 100% of the motor rotation speed).
Figure 2-5 Select the direction of the pump rotation using the direction button ◄|►.
Figure 2-6 Press the ON/OFF button. The indication “t01” will appear for a few seconds on the display indicating that the time period of the first step in minutes, can be programmed.
Figure 2-7 Select the desired time period for the first program step by pressing the buttons ΛΛΛ below the display (from 0 to 999 minutes or 00.0 to 99.9 minutes).
Figure 2-8 By pressing the ◄|► button, the time resolution can be set in minutes or 0.1 minutes. In the 0.1 minute time resolution a dot is displayed, e.g. “00.2”. The time resolution can be set individually for each program step.
Figure 2-9 Press the ON/OFF button. The indication “F02” will briefly appear on the display.
Figure 2-10 Enter the desired flow rate by pressing the buttons Λ Λ Λ below the display, for the second program step.
Figure 2-11 If the ◄|► button is not used to change the direction, the default pump rotation for the set speed is clockwise, ◄| LED ON.
Figure 2-12 Press the ON/OFF button again, the symbol “t02” will briefly appear on the display.
Figure 2-13 Set the time of the second program step.
Figure 2-14 Press ◄|► button, to set the time resolution.

In a similar way up to 99 program steps can be entered.

Remark: It is not possible to end the program after programming the time data.

The direction LEDs indicate if you are programming speed or time:

  • One direction LED is ON: Programming of the flow rate (in the direction indicated by the LED)
  • Both directions LED are OFF: Programming of the time
Figure 2-15 After having entered the time of the last step, press the ON/OFF button.
Figure 2-16 The flow rate (000) of the next step which will not be programmed appears on the display.
Figure 2-17 Press the Remote and Run button simultaneously and you will see the indication “c01” on the display. This indicates that the program will be executed only once and the peristaltic pump will stop afterwards.
Figure 2-18 If you wish to repeat the same program 3 times, increase the cycle number to “c03” by pressing the buttons Λ Λ Λ below the display (from 0 to 99 cycles).
The program can be repeated up to 99 times, indicated by “c99”. If 0 is entered for the cycle number “c00”, the program will run continuously (infinite loop).
Figure 2-19 Press the ON/OFF button until the indication “End” appears on the display to confirm and save the program.
Figure 2-20 To start the program, press the RUN button. The RUN and ON/OFF LEDs are ON.
To stop the running program definitively, press the RUN button. The RUN and ON/OFF LEDs are OFF.

 

Manual intervention during program execution

It is possible to stop the pump by pressing the ON/OFF button, to change the direction and the rotation speed during any running program step. This facilitates urgent replacement of tubing or allows reaction in other emergency situations.

Remark: Do not forget to restore the right direction of the rotation and to switch the pump on again (by pressing the ON/OFF button) after you have finished your intervention.

The time basis in the microprocessor is not stopped during this intervention, so that the total time of the running steps and of the whole program will not be affected. When the program step time has elapsed, the pump will automatically go on with the next program step. Thus, the program is not modified by this emergency intervention.

It is possible to review the program by proceeding in the same way as during programming but without modifying it.
