Output diagrams

  • Fan controls - Q 1 Q 2 Q 3 - in Auto Fan Mode. Applicable to TA692FC-L-1, TA692FC-L-5 Except when Power Off, TA692FC-L is always running at low-fan (Q 1 On).

    ../../_images/output-diagrams-1.png
  • Cooling Valve (Y 1)

    PI control of Cooling Valve (Y 1) in Cool Mode.

    Applicable to TA692FC-L-3, TA692FC-L-4, TA692FC-L-5.

    TA692FC-L employs proportional-integrative modulating control (PI).

    Diagram shows changing in temperature difference versus Y1 voltage level over time.

    Ion icon-valve blinks when output power is under 70%; persistently on at 100%; disppears at 0%.

    Refer to subsequent sections for K-Factor, P-band and I-time settings.

    ../../_images/output-diagrams-2.png
  • Cooling Valve (Y1) in Fan-Only Mode

    Applicable to TA692FC-L-3, TA692FC-L-4, TA692FC-L-5.

    If Fan-Only Mode is selected, Y1 simply shuts off. icon-valve disappears.
