NSTALLATION
- Fix the photocell using the supplied drilling template (fig. 2).
- Make connections as indicated in the previous paragraphs and select
the transmitter power supply with the specific jumper (J1, Fig. 1B):
- Select the same operating frequency on the receiver and on the
transmitter with the specific jumpers (J2, fig 1A & 1B):
Frequency 1: Jumper disabled
Frequency 2: Jumper enabled
- Connect to the specific terminal strip (terminals 3 & 4, Fig. 1B) the safety
edge or external safety device contact to the transmitter. If this option
is not used, jump terminals 3 and 4.
- Connect to the specific terminal strip (terminals 5 & 6, Fig. 1B) the
contacts of the 8K2 resistive edge external to the transmitter. If this
option is not used, do NOT jump terminals 5 and 6.
- Select on the receiver the logic of the NO or nc output contact with
jumper J3.
- Position on the transmitter the probe in the position from the three
possibilities most suitable to the alignment.
- Align the beam to the receiver by adjusting the specific fixing screws "A"
(fig. 2) supplied, both on the receiver and the transmitter.
- With a voltmeter, measure the tension value on the receiver test-point.
(Fig. 2). This value varies according to various parameters, among
which the distance between the photocells. The higher the tension value
on the test-point the better is the alignment. The ideal measure should
be between 0.5 and 0.6 VDC.
- Check that the interruption of the infra-red beam causes the opening of
the normally closed contact of the relay on the receiver and the lighting
up of the red LED.
F
LAT BATTERY SIGNAL
The flat battery situation is signalled optically by the transmitter to the
receiver.
The receiver closes the free LOW BAT contact available in the terminal
strip and activates an intermittent buzzer.
The flat battery indication is given one week before the battery is
completely flat.
Once the batteries have been replaced, switch the receiver OFF then
back ON to deactivate the LOWBAT contact and the buzzer.
However, this will happen automatically after 15 minutes.
