Troubleshooting
This chapter describes how errors at theRFH620 can be recognised and eliminated.
8.1 Overview of errors and malfunctions which could occur
8.1.1 Installation error
¾
The RFH620 has been unsuitably aligned to objects with transponders
¾
Reading pulse sensor has been incorrectly positioned (e.g. internal reading gate
opens too late or shuts too early)
¾
Incremental encoder (optional) positioned incorrectly
8.1.2 Electrical installation error
¾
Interfaces of the RFH620 wired incorrectly
8.1.3 Configuration error
¾
Functions have not been adjusted to the local conditions, e.g. parameters for the
data interface set incorrectly
¾
Device-related limits have not been considered, e.g. reading distance, aperture
angle
¾
Selected trigger source for reading pulse incorrect
8.1.4 Malfunctions during operation
¾
Start/Stop operation: External reading pulse is missing, more than one object is in
the reading area
¾
Device error (hardware/software
8.2 Detailed malfunction analysis
8.2.1 LEDs on the RFH620
The following statuses can, among other things, be read from the LEDs on the RFH620s
housing (see chapter LEDs on the RFH620 housing):
