UPS CONTROL LOGIC

1.0 UPS Control Logic

The UPS Control logic is situated in the centre of the front part of
the UPS. It consists of one rack with 7-8 PCBs (depending on the
system configuration). On the covers of the rack, the various
potentiometers, test points and LEDs are briefly labelled.

A more detailed explanation is given in this chapter.

1.1 Legend of symbols used

 LED (light emitting diode)

- GREEN: normal condition

- RED: alarm condition.

- YELLOW: warning

Potentiometer

- For adjustment
  (only for qualified personnel)

Test Point

- Requires a pin 2mm for
  measurement.

Test point/switch

- Insertion of a 2mm Pin disables
  the described function
