6.18. THE MACHINE DOES NOT READ THE TGS: THE RED LED
ON THE KEY READER IS NOT LIT
This problem occurs when the display does not recognize that a TGS has been inserted in the key
reader, or is unable to access the TGS. This is caused by a problem with the TGS interface
components (TLCBR and key reader and the corresponding connector cables) or by a defective
TGS. It should not concern problems with the CPU, since the initial test checks communication, and
in any case no error message means that the serial communication line between the CPU board and
TLCBR is working properly.
Perform these tests using a TGS known to work properly.
Check whether the BS-TLCBR
cable is intact
Replace the BS-TLCBR
cable
