WARNING
Improper use of the safety sensor may result in serious injury!
Ä Make certain that the entire device and the integration of the optoelectronic protective de-
vice were inspected by qualified and instructed persons (see chapter 2.2 "Necessary com-
petencies").
Ä Make certain that a dangerous process can only be started while the safety sensor is
switched on.
Prerequisites:
• Safety sensor mounted (see chapter 6 "Mounting") and connected (see chapter 7 "Electrical connec-
tion") correctly
• Operating personnel were instructed in proper use
• Dangerous process is switched off, outputs of the safety sensor are disconnected, and the system is
protected against being switched back on
Ä After start-up, check the function of the safety sensor (see chapter 9.1 "Before commissioning and fol-
lowing modifications").
8.1 Switching on
Requirements for the supply voltage (power supply unit):
• Reliable mains separation is ensured.
• Current reserve of at least 2A is available.
Ä Switch on the safety sensor.
ð The safety sensor performs a self test.
Check operational readiness of sensor
Ä Check whether LED1 is permanently lit green or red (see chapter 3.3.2 "Operating indicators on the
MLC510 receiver").
ð The safety sensor is ready for use.
8.2 Aligning the sensor
NOTICE
Faulty or incorrect alignment may result in an operating fault!
Ä The alignment performed during start-up should only be performed by qualified persons (see
chapter 2.2 "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
Loosen the screws only enough so that the devices can just be moved.
