Diagnosis of AS-Interface modules for base mounting
Status display
The status of a module is indicated by LEDs with continuous or flashing light. This enables
diagnostics at a glance:
●
For AS-i communication via a red and green LED.
The following chapters provide an overview of the LED status displays of the AS-i modules.
Status display AS-i / FAULT
All modules have green and red LEDs for the "AS-i / FAULT" status display. For the
functions and remedies, see the table below:
Table 11- 3 Diagnostics of the AS-i status via LEDs
AS-i / FAULT
(green / red)
Possible cause
Possible remedial measures
Green
Normal operation,
AS-i communication OK

Green
Red
No AS-i communication:
•
Master is switched off or offline
Ensure AS-i communication:
•
Switch on the master or switch it to online
mode
•
Slave is not configured in the master
•
Reconfigure the master
•
Incorrect slave type connected
•
Connect the correct module
•
Slave has the wrong address
•
Check/correct the slave address
Flashing green
Red
Module has slave address "0"
(delivery condition)
Assign an address other than "0"
Flashing

Overload of the outputs
Disconnect actuator cables
Check actuators and cables
OFF
No AS-i voltage
Switch on AS-i voltage
AS-i voltage has been connected with reverse
polarity
Connect it correctly
AS-i voltage too low
Measure the AS-i voltage (approx. 24 V DC or
30 V DC)
