Device Status Indicators
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
Test & Reset Installation
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.
Real Time Clock
In case of power outage controller can keep the set internal clock. Retention time: 1 week.
Failure Modes & Quick Repair
# Statement
1 Controller do not react on buttons and status LED is continuous
BLUE or OFF.
2 If Bus A/B indicator LED is continuously RED, then Bus error.
3 If Bus A/B indicator LED is Blinking RED, then controller has more
Digital device on the bus than allowed
4 If two lamps work together than the same short address was set.
5 If the power indicator LEDs flashing up blue for a few second and
then all indicator LEDs are dark.
6 If all indicator LEDs are dark.
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
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.
Take action
Push reset button or power off and
on device
Check Digital bus wiring voltage drop,
wiring short circuit or endpoint limitation
Check Digital device limitation
Reprogram driver or reset Bus A or B by
long-press on PB 1 or 2
The controller cannot be repaired locally.
Contact GE support.
