Diagnosis of ASIsafe F adapters for front plate 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 dual LED
●
For the switching state of the inputs with yellow LEDs
The following chapters provide an overview of the LED status displays of the AS-i modules.
Inputs
Each input has a yellow LED with designation "F-INx". For the functions, see the table below:
Table 11- 1 Diagnostics of the inputs via LED
F-IN x
Meaning
Yellow
Signal activated
OFF
Signal deactivated
Status display AS-i / FAULT
All modules have a dual LED (green/red) for the "AS-i / FAULT" status display. For the
functions and remedies, see the table below:
Table 11- 2 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
—
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
yellow/red
Module has slave address "0"
(delivery condition)
Assign an address other than "0"
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. 30 V DC)
