6.3.- FAULT FINDING

The transmitter and receiver both have status monitoring LED’s, which help to identify

irregularities. The most common signals are contained in the tables below:

TRANSMITTER

LED MEANS

Solid green Transmitter transmitting normally. OPERATION mode.

Green pulses. Transmitter ready for start-up. STAND BY mode.

Red slow flashing Battery level low

Red fast flashing Probably, EEPROM module is not plugged in.

Red double flashing Transmitter cannot start up because a manoeuvre

command is present.

Solid red Transmitter failure

RECEIVER

In OPERATION mode the 5 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:

LED LIT ON OFF

SIGNAL RF signal OK RF signal detection in

SCANNING mode

The receiver is not

receiving RF signals

POWER Power Supply OK Power Supply not OK

HARDOK

Board OK

Slow: fault in the board

Fast: error in EEPROM

Fault in the board

ID ID Code OK (1) ID not recognised

DATA Is receiving the correct

data from a TM70 (1)

Signal received is not

correct

(1): DATA and ID LED’s show a weak flashing when data and ID code are received

correctly, but Start command has not yet been received. Once Start button is pushed

ON; then, DATA and ID LED’s will show the standard strong flashing.
