LED signals
Power LED:
• BLUE = device is powered and in operation
Bus A/Bus B:
• BLUE = Bus status is ok
• Blinking BLUE = communication on the Bus
• RED = Bus error (short)
• Blinking RED = More device than allowed on the Bus
• Blinking PURPLE = Bus test in progress
• Continuous PURPLE = PB1/2 push is active
Status:
• Continuously blinking BLUE = status OK
• Blinking blue quickly = Controller is booting or busy
• Blinking purple slowly = Controller is searching for
endpoints
• Continuous BLUE or OFF = Controller is frozen, perform
a reset
• Blinking red quickly = TLS handshake / Authentication
TEST of connected devices
• PB1 (pushbutton 1) short press: start testing Bus A bus:
lamps start dimming up and down on the bus until
another short press is performed or 5-minute timer is
expired. Meanwhile ‘Bus A’ LED is blinking purple.
• PB2 (pushbutton 2) short press: start testing Bus B bus:
lamps start dimming up and down on the bus until
another short press is performed or 5-minute timer is
expired. Meanwhile ‘Bus B’ LED is blinking purple.
RESET functionalities
• (reset button) short press: restart controller (HW reset,
no software configuration impact)
• PB1 long press (min 10 seconds): reset all Digital devices,
control gears + other devices to reset value on Bus A
• PB2 long press (min 10 seconds): reset all Digital devices,
control gears + other devices to reset value on Bus B
• PB1 + PB2 Long press (min 10 seconds) = reset controller
to factory defaults: empty flash configuration database,
reset passwords and run self-test. All indicator LEDs blink
4 times when device reset.
Real Time Clock
In case of power outage controller can keep the set internal clock. Retention time: 1 week.
