This device requires two power supplies 3.3V – 5.5V for the control system 12V – 24V to drive the motor The Atlas Scientific EZO-PMP™ consists of three main components. Cassette 12 volt motor Control system The actual peristaltic pumping is done within the cassette. It has been designed to be easily detached from the motor and disassembled. 12V The 12 volt motor and control system have been soldered together. Both components are designed to operate as one single unit.
Pump speed vs. voltage There is no change in pump speed at different voltages. 12V 24V = 5 RPM 5 RPM 24V Interupt pin 1When the pump is dispensing the 2 interupt pin goes high. 3 45 “D,10” 40 35 35 30 25 45 45 40 9.8 mL 30 25 20 20 “Cal,9.8” 40 15 15 30 10 10 25 5 5 35 INT *Done 20 15 10 5 Removing cassette 9.8 9.8 G G 5.2 G 2% 1% 1 0% 0 100 200 Turn cassette counterclockwise until it stops. 300 2 400 500 Pull cassette off the motor.
1 2 Removing tube assembly The inner workings of the cassette are fragile and must be dismantled by hand. Using tools can damage or break the cassette. Tube holder ck Cli 1 2 3 Tube Rotor Gently push down the tube holder until it clicks, then remove. Inline tubing connector Turn the cassette around, and carefully remove rotor and pump tube. Installing new tube assembly 1 75mm Measure 75mm of pump tubing, and mark both ends with a soft-tip pen or marker.
3 k Clic Push the tube holder along with the greased and marked pump tube into the cassette until it clicks. k Clic 4 Cassette axle Gently pull out the pump tube, and insert the rotor into the pump tube. Align pump tube and rotor with the cassette axle. Cassette Roller Correct X Incorrect Make sure the pump tube is held between the roller and cassette. Once the tubing has been replaced, run the pump for 3 – 5 minutes to break in the new tubing.
Calibration theory Uncalibrated accuracy +/- 5% Calibrated accuracy +/- 1% Before calibration is attempted all the air bubbles should be removed from the tubing. This is done by running the pump while tapping the tubing. If air bubbles are not removed from the tubing they will slowly group together into larger air bubbles. Over time this will lead to accuracy issues.
Calibration procedure Calibration should be done with water and not a chemical Make sure the tubing is full of water and has no bubbles before calibrating. 1. Instruct the pump to dispense a volume of water. 2. Measure the dispensed amount to determine how much water was actually dispensed. 3. Calibrate the pump by sending it the volume of liquid you have measured. Example Calibrate the pump by dispensing 10ml 1 2 3 45 “D,10” 40 35 35 30 25 45 45 40 9.8 mL 30 25 20 20 “Cal,9.

Mounting the EZO-PMP TM There are a many different ways to mount the EZO-PMP™ Embedded Dosing Pump. If you have a 3D printer you can use the dosing pump stand we created, by clicking here. The dosing pump stand has been measured to perfectly fit the EZO-PMP™ and even has screw holes in place for you to help mount the dosing pump to the stand. Feel free to modify this stand design as needed.
Datasheet change log Datasheet V 1.3 Revised art and added pump head information on pg 11. Datasheet V 1.2 Revised Plock pages to show default value. Datasheet V 1.1 Added mounting information on pg 70. EZO-PMP TM firmware changes V1.0 – Initial release (April 28, 2017) 71 Copyright © Atlas Scientific LLC r 0.
Warranty Atlas Scientific™ Warranties the EZO-PMP™ Embedded Dosing Pump to be free of defect during the debugging phase of device implementation, or 30 days after receiving the EZO-PMP™ Embedded Dosing Pump(which ever comes first). The debugging phase The debugging phase as defined by Atlas Scientific™ is the time period when the EZOPMP™ Embedded Dosing Pump is inserted into a bread board, or shield.
Reasoning behind this warranty Because Atlas Scientific™ does not sell consumer electronics; once the device has been embedded into a custom made system, Atlas Scientific™ cannot possibly warranty the EZO-PMP™ Embedded Dosing Pump, against the thousands of possible variables that may cause the EZO-PMP™ Embedded Dosing Pump to no longer function properly. Please keep this in mind: 1.
