To make it work for us we would need to run a new control cable, install a bipolar supply, and probably install one or two of our spare analog cards to put in analog voltage mode. <br><br>I will draw up a quick schematic and talk with Scot about it. We can keep in our back pocket just in case. <br><br>Best Regards, <br><br>Nick <br><br>----- Original Message ----- <br>From: "Ruben Fair" <rfair@jlab.org> <br>To: "Scot Spiegel" <spiegel@jlab.org>, "Nicholas Sandoval" <sandoval@jlab.org> <br>Sent: Tuesday, August 22, 2017 7:06:02 AM <br>Subject: Hall B Solenoid - Replacement flow controller (temporary) <br><br>Gentlemen, <br><br>If the repair takes too long and/or the new units take too long to get here, is there another flow controller on site that we could borrow as a temporary measure that would suit our needs? <br><br>Regards <br><br>Ruben</div></div><br></div></div></body></html>
