TROUBLESHOOTING
The transmitter and receiver have status monitoring LED’s, which help to identify irregularities.
The most common signals are contained in the tables below:
TRANSMITTER
Transmitter transmitting normally. OPERATION mode.
Transmitter ready for start-up. STAND BY mode.
Probably, EEPROM module is not plugged in.
Transmitter cannot start up because a manoeuvre command is
present.
RECEIVER
In OPERATION mode the 7 LED’s must be lit as has been previously described in section 4.3
Starting. If this is so, press the transmitter manoeuvre buttons and observe the response of the
output relays. If the response is normal, the problem is not related to the remote control
equipment and the installation must be checked. If any of the relays is not activated, the problem
is associated with the remote control equipment. If this happens, observe the appearance of the
LED’s:
Slow: fault in the board
Fast: error in EEPROM
RF signal detection in
SCANNING mode
The receiver is not receiving
RF signals
Is receiving the correct data
from a TM70
Signal received is not correct
There are also two LEDs in the receiver (only available in LR72 electronic card) which informa
about the status of the CAN-BUS. If the CAN connection is not working, check the status of the
LEDs:
