Aligning the sensor
CAUTION
Loss of the safety function due to faulty or incorrect alignment.
Faulty or incorrect alignment can result in failure of the protective function.
Ä
The alignment performed during start-up should only be performed by qualified persons
(Necessary competencies).
Ä
Observe the data sheets and mounting instructions of the individual components.
Prealignment
Fasten the transmitter and receiver in a vertical or horizontal position and at the same height so that
• the front screens are directed at each other.
• the transmitter and receiver connections point in the same direction.
• the transmitter and receiver are arranged parallel to each other, i.e. they are the same distance from
each other at the beginning and end of the device.
Alignment can be performed with a clear protective field by observing the LEDs (see chapter 3.3 "Display
elements").
Ä
Loosen the screws on the mounting brackets or device columns.
NOTICE
Ä
Loosen the screws only enough so that the devices can just be moved.
Ä
Roughly align the transmitter with the receiver.
The receiver of the ELC is equipped with alignment LEDs that detect the optimum state (see chapter 3.3
"Display elements"). The maximum signal level is determined by comparing weaker and stronger levels.
The optimum state can thereby be detected for each distance.
Ä
Before starting the alignment process, briefly disconnect the receiver from the power supply.
Ä
Turn the receiver from left to right until all 4 pairs of the blue alignment LEDs illuminate permanently. As
soon as this optimum point is exceeded, the blue LEDs switch off or flash one after the other.
Ä
Tighten the fastening screws of the receiver.
Ä
Briefly disconnect the receiver from the power supply.
Ä
Now align the transmitter according to the same method, paying attention to the display elements of the
receiver while doing so (see chapter 3.3.2 "Operating indicators on the ELC 110 receiver").
