4.5 Setting up Scan Codes
The Focus II transmitter and receiver has the possibility of coding selection, to minimize interference when
two transmitters can reach one receiver.
NB! Both transmitter and receiver shall be set to the same code. All LEDs on transmitter / receiver ash
twice when code B is set correct, when powering up. Code A will ash once. Please make sure that the total
length of the cable between the transmitter and receiver (required when coding is used, see 5.6) does not
exceed 100 m.
4.6 Choice of Reset Procedure
Reset of Focus II barrier may be reached in three different ways:
A Automatic reset: The barrier is reset directly after the protection area has become clear. Change-over
switch No. 8 is set in position “On” (see 4.4).
B Manual reset: The barrier is reset when the protection area is clear and the reset button has been
pressed and released. Change-over switch No. 8 is set in position “Off” (see 4.4).
C Pre-reset: The barrier is reset when, f irst, the pre-reset button, which is normally placed inside
hazardous area, has been pressed (the yellow LED 5 in receiver is blinking) and, thereafter, if the
protection area is clear, within 8 seconds the reset button outside the area has been pressed and
released. (See 4.4 and 8)
