[. . . ] Remove screw holding access cover on underside of pump and remove plate. Withdraw connector and attach to battery terminals. A lithium U9VL is preferred due to its long shelf life and higher capacity (about twice the operating time as an alkaline) although an alkaline will suffice. Make sure that the removal ribbon is below the battery. [. . . ] Bi-directional control is possible using this mode. Set the SPEED SOURCE to EXTernal and apply the voltage via the center ring of the 3. 5 mm stereo phono jack input at the top of the control panel. 5 EXT speed input GND Set voltage monitor Stereo jack connections for EXTernal speed control The control voltage passes through the speed control potentiometers and can be attenuated via the knob settings. This is a useful feature when operating more than one pump from a common control line since it allows individual speed adjustment for each pump. It is also useful when a digital level is used as a control voltage. The input parameters are as follows: Ensure that maximum MONITOR VOLTAGE (after knob attenuation) does not exceed ±1. 75 volts. An input of +1. 5V will produce a MONITOR voltage of about ­1. 75V when the dials are at 100 and 10. Zero volts = Zero flow rate (actively controlled). CMOS is usually close enough to work directly. Positive Control voltage will cause the rotor to rotate clockwise (outflow will be on the top). Negative control voltage will cause the rotor to rotate counterclockwise (outflow on the bottom). To establish the maximum dial setting (assuming you desire full motor speed at your full peed signal): 1. Apply the maximum control signal that your system will deliver. Increase the dials until the MONITOR voltage reaches a maximum of 1. 75V. You may now perform a calibration of Flow vs. Monitor voltage as detailed below by either varying the incoming sig6 nal or with a constant input and varying the dials. Remember not to exceed the values determined in step 4 above. You may leave the switch in this position and stop the pump by applying zero volts to the control input. Calibration Instech's peristaltic pumps use tube sets of different sizes to cover the range of flow rates from 0. 2 to 180 ml/hr (see chart below). To determine the flow rate at a given rotor speed you will need to calibrate your pump. We have designed our pumps so that the relationship between the rate setting on the controller and the rotor's speed is extremely linear; therefore, in most cases you only need to perform a single-point calibration. For maximum accuracy, we recommend that you calibrate each pump tube that you use, since each tube set may vary slightly. 180 160 140 120 100 80 60 40 20 0 0 10 20 30 40 50 60 70 80 90 . 031" ID . 020" ID . 015" ID . 062" ID . 093" ID 100 110 Dial Setting (INTernal speed control) 1. Attach either the inflow or the outflow tube to a container on a balance, or one whose weight is precisely known. Ensure that all the air has been removed from the lines. [. . . ] For example, LL-020S-22 specifies a single channel . 020" silicone tube with a male Luer lock inlet connector and a 22 gauge hypodermic tubing outlet connector. Note that you can have different inlet and outlet connectors on the same tube set.
