Claims under the warranty rendered void!
The housing of the LMS5xx is sealed. Type-dependent, the devices have a diffent quantity
of sealing stickers across their components (LMS500 Lite/PRO, LMS511 Lite/PRO,
LMS531 Lite/PRO, LMS581 PRO: two stickers, LMS511 Heavy Duty: three stickers).
Claims under the warranty against SICK AG will be rendered void if the screwed housing is
opened and/or the seals are damaged. The housing is only allowed to be opened by SICK
authorized service personnel.
The only exception in this case is the process of replacing an LMS500 Lite/Pro Indoor or
LMS511 Heavy Duty Outdoor with an appropriate replacement device. Here, the system
connector is transferred from the existing device to the replacement device for automatic
configuration purposes. See section 8.2 “Exchanging an LMS5xx” on page 91.
8.1 Maintenance during operation
8.1.1 Cleaning the front screen
The LMS5xx laser measurement sensor is largely maintenance-free. The front screen on the
LMS5xx should however be regularly cleaned and also if contaminated.
Do not use aggressive detergents.
Do not use abrasive cleaning agents.
Important Static charges cause dust particles to be attracted to the front screen.
You reduce this effect by using the antistatic plastic cleaner (SICK part no. 5600006) and
the SICK lens cloth (part no. 4003353). See section 11.1 “Ordering information” on
page 115.
How to clean the front screen:
1. Use a clean and soft brush to remove dust from the front screen.
2. Wipe the front screen with a clean and damp cloth (antistatic plastic cleaner).
8.2 Exchanging an LMS5xx
Incorrect or damaged LMS5xx have to removed and reclaped with either new or repaired
LMS5xx of the same type.
Important Do not make any repairs to the device!

components of the LMS5xx.
The following parts can be replaced by the user:
Sensor with all components as complete replacement device unit
Only possible with LMS500 PRO/Lite (Indoor) and LMS511 Heavy Duty (Outdoor):
Sensor as replacement device using the former system connector (with cloning
parameter memory).
