The Over Tem per a ture Sta tus or OT sta tus is "1" in case of an over tem per a ture,
the OT LED will be on and the out put shuts down. As a pre-warning the OT LED
starts to blink when the unit runs hot but the sit u a tion of over tem per a ture is not
reached yet. The sta tus will still be low when the LED is blink ing.
The Cur rent Con trol Sta tus or CC-status out put is "1" when the unit is in
CC-mode.
The Power Sink Over Load Sta tus or PSOL-status out put is "1" when the op tional
Power Sink is over loaded or over heated.
The AC-Fail Sta tus or ACF-sta tus out put is "1" when the in put volt age is be low
115V (peak, not rms) for more than 10 ms. Note that if you want the ACF-sta tus to
switch be fore the DCF-sta tus, the hold-up time has to be > 10 ms. This can be
achieved by re duc ing the load, see para graph 25) of this chapter.
The DC-Fail Sta tus or DCF-status out put is "1" when the out put volt age is ei ther
5% be low or above the set point.
When the unit is in CC-mode, DCF will al ways be "1", see pre vi ous para graph 7).
15) STATUS RE LAY OUT PUTS
The power sup ply has 2 sta tus re lay out puts, with each a change-over con tact.
They are con nected to con nec tor CON D. The pins 1, 2, 3 are con nected to the
DCF-re lay and pins 4, 5, 6 to the ACF-re lay (see fig. 3 - 10). Pin 1 is the up per
out put, clos est to SW1.
