LED 1

MAINS PRESENT

• Green LED is continually illuminated = Mains O.K.(rectifier).
• Green LED flashing BUZZER beeping slowly (approx.

every 2 sec.) = Mains is not O.K.

LED 2

RECTIFIER

• LED off = Rectifier is not supplied
• Green LED is continually illuminated = Mains and rectifier O.K.
• Red LED flashing fast + BUZZER beeping fast (every sec.) =

Rectifier failure

LED 3

BATTERY SWITCH

• Green LED is continually illuminated = Battery switch closed
• Green LED flashing fast + BUZZER beeping fast (every sec.) =

Battery switch open

LED 4

BATTERY DISCHARGING

• Yellow LED is continually illuminated = Battery feeding inverter
• Otherwise LED is off.

LED 5

BATTERY CHARGING

• Green LED is continually illuminated = Battery charging
• Otherwise LED is off.

LED 14

BYPASS POWER SUPPLY

• Green LED is continually illuminated = Mains O.K.(Bypass

supply).

• Green LED flashing BUZZER beeping slowly = Mains

out of order or not present, or IRE open.

LED 15

MAINTENANCE BYPASS SWITCH

• Red LED is continually illuminated = Maintenance bypass

switch closed

Note:

For parallel and hot-standby systems, it may be any

maintenance bypass within the system that is closed.

• Otherwise LED is off.

LED 16

INVERTER

• Green LED is continually illuminated = Inverter O.K.
• Red LED flashing fast + BUZZER beeping fast = Inverter
