15 - FRONTAL LEDS OPERATION
15.1 - the frontal leds of the RX during the normal operation of
the detector, give out the following indications (see fig.9):
• normal operation: the blue led flashes every 10 seconds
• alarm: the red led is constantly ON
• limit of compensation, interrupted beam, fault: the blue Led
flashes every second
16 - MAINTENANCE
16.1 - the instrument requires an easy and periodic maintenance.
It can be programmed or made automatic using remote signaling
of the detector.
During the normal operation and after a certain time from
installation, if maintenance is not performed, the detector, because
of the dirt and dust deposited on the front of the covers, gives out
a fault output signal, because of the decrease of the signal below
the limit of compensation.
Then it will be time to proceed to cleaning in order to reestablish
the initial optical conditions.
16.2 - The operations to be done are the following :
• remove power supply
• verify the inside terminal board tightening the terminals in the
case they are loose
• verify the optical alignment in case some changes of the structure
on which the detector is installed. In this case repeat the operations
of chap.8
• perform the cleaning of the front covers of TX and RX.
We suggest to use a wet cloth with water with some trace of soap.
Chemical products like alcohol, ammonia and similar must not be
used. The cleaning of the frontcover is fundamental for the good
operation of the device
• power up the devioce
17 - SENSITIVITY SELECTION
17.1- Afer the installation and after some working time, if you
want to modify the sensitivity of the detector, read what follow:
• remove the cover of the receiver (it is not necessary to power
off the detector)
• modify the sensitivity acting on the SW2 selector
• close the cover
