The power and status LEDs at the EXCEL WEB II controller indicate the controller´s
statuses and allows troubleshooting. Please refer to the following tables that
describe the behavior, meaning and necessary action to check status and solve
errors and/problems.
Power LED (green)
Meaning
Normal operation
Power supply not OK
Status / Alarm LED (red)

The application has a fault or
The controller has been powered up without an
application or
The operator has manually stopped the
application, e.g., using XW-Online. In this case,
the LED will light up 13 minutes after power-up
without application
Sensor failure of analog input
Communications failure on Panel Bus
RS485-1 Send (Tx) / Receive (Rx) LED (yellow)
Meaning
Normal operation, RS485-1 is functioning
properly
No RS485-1 communication
RS485-1 communication is switched off but
controller is receiving data from other controllers
Controller is trying to establish a RS485-1
connection but there is no answer
,
Application LEDs (yellow)
NOTE:
The LED can be used to display application-dependent status information
like "Cooling Mode", "Heating Mode", "Service Interval" etc.
