11.12 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 Possible cause
(green / red)
Green Normal operation,
AS-i communication OK
Green No AS-i communication:
Red
Master is switched off or offline
•
Slave is not configured in the master
•
Incorrect slave type connected
•
Slave has the wrong address
•
Flashing green Module has slave address "0"
Red (delivery condition)
Flashing Overload of the outputs
alternately
green/red
1
OFF No AS-i voltage
AS-i voltage has been connected with reverse
polarity

Possible remedial measures
—
Ensure AS-i communication:
Switch on the master or switch it to online
•
mode
Reconfigure the master
•
Connect the correct module
•
Check/correct the slave address
•
Assign an address other than "0"
Disconnect actuator cables
Check actuators and cables
Switch on AS-i voltage
Connect it correctly
Measure the AS-i voltage (approx. 24 V DC or
30 V DC)
