ISCO PUMP LABVIEW DRIVER

All D-Series pumps have mechanical and electrical fail-safes, in addition to the factory default or user-set limits. The 30D High Pressure Syringe Pump takes traditional syringe pumps to the next level of deep well core analysis. Dispense Mode Tech Bulletin. As RavensFan wrote, check your values. Is this an option? Can you provide measurement data for such a reaction? Actually the Initial pressure minimum is and you use

Message 10 of Message 6 of 8. I’m unsure what else you require? When cold starting the VI in automatic control mode with true for reinitialize, the PID controller sets the pressure to the minimum and then slowly brings it back up to the setpoint value.

Extension Cables Tech Bulletin. How fast does your system react?

All ISCO Lagview pumps use the same controller that can operate any four pump modules, either independently or together. When you purchase instruments from Teledyne ISCO, you not only receive innovative, high quality products, you also receive excellent customer service and product support. Why do you use the Autotuning version of PID? Not only does it handle exceptional low-flow stability with ease, but it gives you the ability to reach pressures of 2, bar 30, psi.

Should have looked a few pages farther in then manual. Message 1 of 8. Message 1 of Message 9 of Without any derivative action, I tried a variety of values for both P and I ranging from 0 to 10 and I cannot seem to find one that allows for the system to stabilize. However caused and on any theory of liability, whether in contract, strict liability, or tort including sico or otherwise arising in any way out of the use of the provided driver or software, even if advised of the possibility of albview damage.

Chemyx does not provide technical support for the driver and software described here. This occurs even if the original process value is close to the setpoint feeding the process value into the PID controller before running also does not help. Actually the Initial pressure minimum is and ieco use Message 3 of 8. I did find another forum thread with a similar issue, but none of the solutions posted there seemed to have helped me. The amount of pressure applied is related to vertical displacement through jsco equation that is shown in the attached VI.

Oddly, the system appears to be the most stable with the PID parameters that I previously used in the screenshot before. Install the driver according to the installation instructions in the manual provided. Here is the link to that forum thread:. I am not sure whether or not this is a result of poor PID tuning, but after the initial bump during transition from manual to automatic, the PID controller seems to be able to maintain the correct pressure nicely.

I did this twice to show what happens when I transition back and forth.

I tried finding better PID gains using the trial and error method as described in the following link, but I still have not managed to get the system to stabilize. Overview Specifications Documents Support.

And your loop is set to iterate at ms loop rate in your VI – a really bad combination….

Oabview I said, I think it’s a formatting issue rather than a coding one, and I’ve not seen the error code I’m recieving before.
