LMS5xx Laser Measurement Sensors
Chapter 2
Risk of injury/risk of damage via electrical current!
Potential equalization currents between the LMS5xx and the peripheral devices can have
the following effects:
Dangerous voltages on the metal housing, e.g. of the LMS5xx
Incorrect function or irreparable damage to the devices
Damage/irreparable damage of the cable shield due to heating and cable fires
Where local conditions are unfavorable and thus do not meet conditions for a safe
earthing method (same ground potential at all grounding points), take measures
according to chapter 6.2 “Conditions for safe operation of the LMS5xx in an
installation” on page 63.
2.9 Quick stop and restart
2.9.1 Switching off the LMS5xx
LMS500:
Switch off the voltage supply (power supply).
LMS511/ LMS531/LMS581:
Switch off the voltage supply (power supply) or disconnect the M12 supply cable on the
device.
The LMS5xx retains configurations parameters stored in the internal, non-volatile memory.
Measured values on the data interface are lost.
2.9.2 Switching back on the LMS5xx
LMS500:
Switch on the voltage supply (power supply).
LMS511/LMS531/LMS581:
Switch on the voltage supply (power supply) or re-connect the M12 supply cable on the
device.
The LMS5xx re-commences operation with the parameters last saved.
2.10 Environmental protection
The LMS5xx has been designed to minimize environmental impact. It uses only a minimum
of power.
2.10.1 Power consumption
While working, always act in an environmentally responsible manner.
LMS5xx variant Max. power consumption during operation
LMS500 Sensor: Max. 25 W (without load on the outputs)
LMS511/LMS531/LMS581 Sensor: Max. 25 W (without load on the outputs)
Heating: Additionally max. 65 W
