If the green led of the button panel lights up and the unit does not work we will check the

state of the Led diodes, green, of the receiver.

1. With the transmitter turned off check the power led. If it does not turn on, check the

voltage, feed connection and the fuse. If these are not the cause, substitute the card.

2. If the Power led lights up, check the Hard led, if the Hard led does not light up, substitute

the eeprom of the receiver with the eeprom of the transmitter. If it lights up with the led of the

transmitter, copy the eeprom of the transmitter to the receiver and if it still does not light up with the

eeprom of the transmitter, substitute the LR70 card.

3. If the Power and Hard leds light up, with the button panel turned off, check if the

signal led lights up occasionally. This led lights up whenever it receives a radio signal. If it never

lights up check the state and the connection of the antenna and if it is not corrected, substitute

the LR70. If it lights up very often, this may mean interferences; check whether there is any button

panel with the same frequency.

4. If we have made sure that the Power and Hard led light up and the Signal led lights up

occasionally. Turn on the button panel and keeping the start button pressed, check that the

signal led is always lit up and the data leds (correct signal) and ID (code OK) blink very rapidly. If

they do not, substitute the LR70 and carry out operation tests; if it continues to fail, replace the

LR70 and substitute the transmitting logic

1.Unscrew the four screws to open the

cabinet.

2. Disconnect the EEPROM of the receiving

logic card.

3. Release the feed terminals and and relay

outputs which are connected to the receiving

logic.

5. Unscrew the five screws of the receiving

logic.

4. Unplug the antenna connector.

6. Remove the receiving logic taking caution

with the antenna patch cable and substitute

with a new one. Repeat the steps for

assembling the receiver in reverse.
