Fault diagnosis
SD card is removed while output is activated
If the SD card is not inserted, RFID Access Management cannot run on the RFID
interrogator.
If the SD card is removed while the output is activated, the output retains the same status
it had when the card was removed.
If the door is not triggered by a signal edge, this can result in the access point remaining
open.
Tag is not read by the configuration device
If the tag cannot be read by the configuration device, this may be because the tag is being
held too close to the reading range or has been placed directly on the device.
Hold the tag at an appropriate distance within the reading range.
