Protection beams (optional, but recommended)
An infrared beam, or underground loop across the gate entrance may be connected
to the controller as an additional safety feature. When a motor vehicle activates the
loop or beam the following occurs:
!
If the gate is closing, it will immediately stop and reopen
!
If the transmitter or intercom gate release pushbutton is pressed while the beam
is broken, or the loop activated, the gate will remain open. The Autoclose time will
restart its countdown
Origin sensor fail (A10 only)
Lightning protection
The A10 operator uses an origin switch to ensure it stops in the correct open and
closed positions. If this switch fails for any reason, the operator will shut down. To
provide indication to the user that there has been an origin sensor failure, the
status LED will flash three times every two seconds.
This condition is treated as serious and the unit cannot be activated again until the
gate has been moved manually either fully-open or fully-closed, ensuring that the
gate magnet has passed the sensor. If the sensor registers correctly, the unit will
reset, and can be operated again. If the sensor does not re-register, the unit will
remain in the locked state.
If the system cannot be reset by following the procedure above, it is a clear
indication that the SENSOR is faulty or not switching reliably. It is important that
the operation of the SENSOR is checked by a qualified technician.
All CENTSYS controllers have onboard lightning protection. The protection circuitry
was designed in conjunction with the CSIR. Provided that the system has been
properly earthed the protection will significantly improve the resistance of the
system against lightning strikes.
