User’s Manual

general

The control panel on Galaxy PW™ UPSs comprises the basic controls and indica- tions required to check the general status of the system (see figure 14).

Located in the upper right part of the cabi- net front, the control panel is designed to provide an easy and rapid overview of system status (see figure 14). Interpretation of symbols is very simple and requires no particular training. The information concerns only the cabinet on which the panel is located.

The panel indicates:

■normal operation (load protected);

■operation with load on battery power;

■abnormal situations (operating problem);

■dangerous situations (load not protect- ed).

indications

See figure 14.

"Rectifier/charger" light 1

■light off: rectifier/charger OFF;

■light shines green: rectifier/charger ON;

■light shines red: rectifier/charger fault, the stored alarm indicates one or several of the following faults:

❏ input circuit breaker Q1 open,

❏ protection fuse at the rectifier/charger input (FUE) blown,

❏ abnormally high internal rectifier/charger temperature,

❏ abnormally high battery charge current, ❏ abnormally high battery voltage,

❏ fault, non-calibration or non-personaliza- tion of the electronic control board for the rectifier/charger,

❏ fault on the electronic power-supply board,

❏ abnormally high temperature in the har- monic filter inductor.

"Static-bypass" light 3

■light off: bypass AC source within speci- fied tolerances and static bypass open;

■light shines green: static bypass closed;

■light shines red: the stored alarm indi- cates one or several of the following faults:

❏ bypass AC source voltage or frequency outside specified tolerances,

❏ static-bypass fault,

❏ abnormally high internal static-bypass temperature,

❏ static-bypass ventilation fault,

❏ power-supply fault for the static-bypass control function,

❏ fault on the electronic board controlling the transfer function,

❏ non-calibration or non-personalization of the electronic control board for the invert- er,

❏ fault on the electronic power-supply board,

❏ fault on monitoring the "inverter ready" response channels (parallel UPS system).

"Battery light" 2

■ light off: battery float charging;

■ light flashing green: battery recharging;

■ light shines green: load on battery power;

■ light flashing red: low-battery shutdown warning;

■ light shines red: battery at end of back- up time and circuit breaker QF1 open, or battery fault.

"Inverter" light 4

■light off: inverter OFF;

■light flashing green: inverter starting, inverter ON but not connected to the load;

■light shines green: normal inverter oper- ation;

■light shines red: inverter fault, the stored alarm indicates one or several of the fol- lowing faults:

❏ inverter shutdown due to inverter output voltage outside specified tolerances,

❏ protection fuse at the inverter output (FUS) blown,

❏ abnormally high inverter-output trans- former temperature,

❏ abnormally high inverter temperature,

❏ output-voltage fault (amplitude or phase) (parallel UPSs),

❏ fault, non-calibration or non-personaliza- tion of the electronic control board for the inverter,

❏ fault on the electronic power-supply board.
