Alarm output R (PRO: pin 4 and pin 6, Lite: pin 3 and pin 4) can not be configured as it serves
as a reference output. PRO: pin 4 and pin 6 respectively Lite: pin 3 and pin 4 are internally
connected (0
). See also section 6.5.5 “Wiring of inputs and outputs on the LMS5xx” on
page 82).
3.11.5 Synchronisation of several LMS5xx
Optical interference between two or more LMS5xx can occur if they have to be installed
within the same scanning plane (see section “LMS5xx with Weather protection hood (part
no. 2063050)” on page 60).
Several LMS5xx can be synchronized to avoid this type of interference. Through the SOPAS
software an LMS5xx can type-dependently be set and sychronized with other LMS5xx via
assigned outputs and inputs:
Using the Synchronisation Phase value (range: –180 … +180°) in the SOPAS software each
Master-Slave link can be differentiated.
The synchronisation feature can also be used to increase the scanning frequency of an area
by placing several units over the same area and adjusting the phases to alternate scanning.
