Description of indicators (LEDs)
FOSTER RX boards have 6 indicators (LEDs) used for control purposes, which can
be enabled by moving the jumper on the two-pin connector marked as LEDs to
position ON.
It is generally advisable to move the jumper back to position OFF at the end of the
testing phase.
LED S.LOW: low signal (DISQUALIFICATION)
LED S.LOW switches on to indicate the presence of “
intense mist
”. If intense
mist is detected, the barrier does not initially generate an alarm message
signalling a missing signal, but switches the S.LOW LED on, issuing the signal
DISQUALIFICATION on the terminal board (open collector).
LED MASK: Blinding signal
LED MASK switches on and blinks to signal that the infrared signal detected has
a modulated intensity above the one of the signal used.
Note: this LED is generally OFF in ordinary operating conditions. If the LED
continues to be lighted or blink, increase the blinding immunity by adjusting
trimmer MASK (turn it clockwise to increase sensitivity).
LED DETECT: Beam interruption detection
Regardless of the alarm output resulting from the tripping delay, which can be
adjusted with trimmer SPEED, LED DETECT always switches on when the
beams of the barriers are obstructed for a long or short period of time.
Note: this LED is generally OFF in ordinary operating conditions. The LED blinks
if one or more transmitter signals are not detected.
The LED lights permanently if no signals are detected from all the transmitters or
if one or more receivers are blinded or incorrectly aligned.
LED ALM: Alarm acknowledgement
This LED is normally OFF and switches on to signal the presence of an alarm.
The alarms of FOSTER barriers depend on the tripping delay set on trimmer
SPEED, which can range from a minimum of 50 mSec to
500 mSec (turn the trimmer clockwise to increase the delay).
LED HTR: Heating system enabling acknowledgement
FOSTER barriers have an automatic heating system with electronic control that
guarantees a minimum internal temperature of 17°C in all environmental
conditions.
If the LED is on, the heating system is working correctly.
POWER: power supply
LED POWER is the only one that is permanently on in ordinary operating
conditions. It is used to indicate that the board is correctly powered.
