EL20
First powering up
• At first powering up, after the columns have been fixed one in front of the other, the beams are automatically synchronized by
the optical signal.
• The Coding of TX coupling with RX is performed automatically
• The receiver Led indicates any malfunctions:
- Led OFF: relay closed, barriers are functioning correctly
- Quick-flashing Led: see section titled “Troubleshooting”

Trouble
Led is lit with fixed light
and the relay contact is
open.
Led is flashing and the
relay contact is open
Led is always OFF and
the relay contact is open.
Led is lit with fixed light
and the relay contact is
closed
Led is always OFF and
the relay contact is closed.
Possible Cause
• Incomplete acquisition of random code
• Power supply to TX column missing
• Barrier is excessively off-center
• Range selection jumper is not set correctly
• RX column fault
• Power supply to RX column missing
• Alarm memory enabled
• TC present
Corrective Measure
• Check that there are no obstacles
between barriers
• Supply TX column
• Re-position barriers
• Check the distance between barriers and
select the correct range
• Check the RX column and replace, if
necessary
• Supply RX column
• Arm the system and disarm, if necessary
(refer to the TC input)
• Arm the system and check connections
