A1: Transponder is not being detected
A few transponders are not being detected.
If this is the case, the problem is most likely related to the individual transponder
or the positioning of the transponder.
- Check the mounting position of the transponder, for more information
check your transponder manual.
None of the transponders are being detected.
If this is the case, the problem is most likely related to the detection loop,
decoder, timing computer or cabling. Please take the following steps:
- Check if the loop in the display changes to black during a transponder
passing. If this is working, but nothing appears on the computer screen,
check the cabling between the decoder and the computer.
- Check the coaxial cable by measuring the resistance (with multimeter)
between the center pin and the outside of the BNC connector. The reading
should be approximately 100 kOhm after 30 seconds. If not, the coaxial
must be replaced.
- Check the loop wire by cutting the loop wires from the connection box
and measuring the resistance between the loop wires in the track. The
reading should be approximately 470 Ohm. If this is not the case, the loop
must be replaced. When (re)connecting the loopwires to the connection
box please solder with proper connections (for more information please
check your system installation manual).
Error messages
- Activator overload: This means that the overcurrent protection of the
activation circuit is working. A possible cause is a short circuit in the
coaxial cable, or the use of an incorrect loop or connection box.
- Activator hot: This means that the temperature of the activator circuit
is too high. The decoder must be used at ambient temperatures below
50C/122F, otherwise problems with the loop may occur.
