[Dsg-halla_magnets] CLEO Controls wiring

[Steven Lassiter]

Hello,

 The following CLEO control rack wiring needs to be addressed.

 1. HX PT thermometers.  Cable 507-01 and 507-02 have crossed wires at the terminal strip HX-TS-01 in relationship to drawing A00000-16-03-0212 sht 2/2.
    I can not tell which probe was the He gas vs the LN2 temperature probe. I made a guess on the calibration data for now, but the wiring needs to be addressed or the drawing updated.

 2. Liquid level signals - are they mA or V signals?  Drawing A00000-16-03-0220 shows pin 4 and 8 being used to feed directly into the I/O card #8.
    a. the cables 220-01 and 220-02 are wired just for pins 4 and 8. Pin 8 is not the ground for 4-20mA Pins 8 and 9 are the pins for the Loop power for using 4-20mA signals and pin 5 is the signal ground. Pin 3 (+) is the 0-10V signal option.
    b. The A-B 1756-IF16 module is shown on drawing A00000-16-03-0308 as being configured just for single ended voltage, not current.
    c. Choose a signal type - voltage or mA.
        i. if Voltage is chosen, then rewire the cable connector for 220-01 and 220-02  using pins 3 (+) and 5 (gnd) and add a Dataforth signal conditioners (10V in = 10V out) to the rack, along with cables.
       ii. if mA is chosen, then rewire 220-01 and 220-02 using pins 4 and 5 and adding pins 8 and 9 to have power to energize the mA circuit. Then re-configure the 1756-IF16 module to accept mA signals for the Liquid level channels.
  d. update drawings to match the option chosen.


I will look into the problems with the radial strain gauges J, N an F later today, hopefully.

Thanks
Steven
