SOLA 4000 - Operating Panel
LED 18 LOAD FED BY BYPASS POWER SUPPLY
• Yellow LED is continually illuminated = Load fed by static
bypass
• Otherwise LED is off.
LED 19 LOAD IS SUPPLIED
• Green LED is continually illuminated = Load fed either by
inverter or by static bypass and IUG is closed
• Otherwise LED is off.
LED 27 BATTERY TEST
This test is only performed if the batteries are fully charged. Other-
wise the test is skipped and performed in the following month.
• LED off = BATTERY TEST function not active
• Green LED is continually illuminated = BATTERY TEST func-
tion activated, but UPS is not performing the test
• Green LED flashing slowly = BATTERY TEST running
• Red LED flashing fast + BUZZER beeping fast = BATTERY
TEST failed. Test battery capacity.
LED 28 E.P.O.
• Red LED is continually illuminated = E.P.O. has been activated
Note: For parallel and hot-standby systems, EPO may be have
been activated at any unit.
LED 26 STATIC SWITCH
• Green LED continually illuminated = Bypass available
• Green LED flashing = Bypass not synchronised but the mains
is OK
• LED off = Mains not OK
LEDs BATTERY INDICATOR
a) During the charging phase (green LED L5 ON)
• Green LEDs continuously illuminated indicate the actual battery
autonomy as a percentage of the nominal battery autonomy,
depending on the actual load and battery charging status.
b) During the discharging phase (yellow LED 4 ON)
• If, during the discharging phase, the actual battery autonomy
goes below 20% autonomy, the system signals the alarm "Low
Battery ".
- The BUZZER beeps continually.
- The colour of the "battery indicator" LEDs changes from green to
red.
• The actual autonomy is signalled by the flashing of the corre-
sponding LED.
• When the LED corresponding to 0% autonomy starts flashing:
- The buzzer beeps continually and cannot be muted.
- The inverter will cease to operate soon.
