## **S ecifications p** 

## **Diagnostic** 

If a fault occurs on either the emitter or receiver the Alarm LED and output will turn ON. 

## **Receiver fault** 

During normal operation the receiver is monitored for faults. 

If the wires are short-circuited the “Code A, Yellow LED” flashes at a rate of 2 Hz. 

If the wires are broken the “Code A, Yellow LED” flashes at a rate of 4 Hz. 

## **Emitter fault** 

During normal operation the emitter is monitored for faults. 

If the wires are short-circuited the “Code B, Green LED” 

flashes at a rate of 2 Hz. 

If the wires are broken the “Code B, Green LED” flashes at a rate of 4 Hz. 

## **Alignment** 

If the alignment DIP switch is set the Yellow Signal LED Flashes according to the signal quality. 

Low frequency means weak signal. 

Steady indication means maximum signal. On long distance it is not possible to get a steady signal but the alignment is optimal when the led flashes with the highest frequency. On short distance the sensitivity can be reduced using the potentiometer and then 

get better readings in the alignment LED. 

The ALARM output will follow the Signal LED in alignment mode, so a Sensor tester (optional) can be connected to serve as a remote indication during alignment of the sensors. **NB!** In alignment mode the output is off. 

## **Code A or B** 

When two sensor pairs are mounted close to each other it is recommended to select one set to Code A and the other to Code B to minimize crosstalk. 

## **Dirt reserve** 

For optimal detection excess gain settings can be selected using the Level Low/High DIP switch: • High: Allows high dirt build-up. 

• Low: Allows detection of semi-transparent objects. 

## **Power settings** 

To avoid a too strong emitter the power can be reduced to 50% reducing the max distance to 25%

## **Mode of O eration p** 

A multiplexed system consists ger signal out) to pin 11 (trigof 1 master amplifier which ger signal in). The multiplex ini tial is es the multiplex cycle cycle is re initialized au to mat i- with a trigger signal, and up cal ly by the master each 350 to 10 slave amplifiers conms or, immediately after the nect ed to geth er in a loop via last slave amplifier in the loop the trigger signal. Pin 9 (trighas been activated, if the trig- 

ger output of the last slave amplifier is connected to the trigger input of the master. Each photoelec tric switch has its own amplifier with a relay output. A multiplexed system allows the use of up to 

11 long range photoelectric switch es mount ed near one another, without having false out put sig nals due to optical cross talk.
