Purchase Includes

  • SLICE-QT Temperature Control Unit
  • AC power cord with appropriate wall plug for you location (if known)
  • Four single-ended 6-ft control cables1)

List of Symbols

Warning. Pay special attention to procedures and notes.
Potential for electrical hazard.

Getting Started

  • When presented with a given view, it is possible to select the functionality or change the values in any field bordered in blue. When a particular field is actively being edited, its border will be yellow.
  1. Using table 1, make connections from the SLICE-QT to your thermal plant via the cables supplied by Vescent. Ensure the shield of the cable is well connected to the metal sleeve on the cable connector.
  2. Use the supplied AC power cord to provide power to the SLICE-QT. The power converter inside the unit will accept any line voltage within the range in table 2.
  3. Turn on the SLICE-QT with the power switch on the back of the unit located on the power entry module.
  4. Touch a Channel Label icon to enter the Channel Details screen.
  5. Touch the Setpoint Temperature Icon to enter in the desired set point temperature.
  6. Touch Settings > Limits
    1. Set the absolute minimum and absolute maximum temperature allowed for your plant.
    2. Set the lock range. This range determines over what value of ∆T = Tact - Tset the system is considered to be locked. If ∆T is outside of this range, the Error field will change from green to yellow. This range will appear as yellow dashed lines on the plot of ∆T vs. time on the Channel Detail screen.
  7. Touch Settings > PID
    1. Set the PID parameters for your plant
      1. Touch each window to set the given parameter
      2. We recommend the Ziegler-Nichols method of setting your PID parameters2)
  8. Touch the OFF icon to engage the temperature servo
  9. Monitor on the performance screen to ensure system settles
