Figure 9: Display messages

LCD Display

An LCD display, capable of showing two rows of 40 characters, is used to indicate the UPS operating parameters, warnings and alarms.

A DIP switch fitted to the display microprocessor board enables the displayed language to be easily selected to English, French, Italian, Spanish or German.

The lower row of characters are used to display metered parameters; which include output (or bypass) voltage, frequency, or current together with battery current & voltage and autonomy time for SMF batteries only.

Warning and alarm messages are displayed on the upper row of characters. The ALARM led and audible warning accompany all alarm messages but are not activated by

warning messages. In all cases, the message automatically resets when the alarmed (or warning ) condition reverts to normal.

When two (or more) alarm or warning conditions are active simultaneously, the appropriate messages are displayed in a cyclic fashion, with each message appearing on the display for approximately for 10 seconds.

1.2.9Battery Circuit Breaker

1.2.10Battery Cabinet / Rack

For all kVA Models battery circuit breaker can be provided either in auxiliary cubicle or in a separate box. This box is designed to be wall mounted and is connected between the UPS and battery bank.

The batteries associated with the UPS are generally housed in a purpose built cabinet / rack located alongside, but not attached to the main UPS equipment.

It is possible to install batteries of various types and capacities in the cabinet / rack to obtain required autonomy characteristics.
