11Control Panel
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.
"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.
"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).
"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.
