The following list provides an overview of the required installation steps:
•
Connect the LD-MRS to the supply voltage
•
Connect the PC temporarily (configuration)
•
Measuring mode: Turn on the data interface for operation (depending on the use)
- or -
•
Field monitoring: Wiring of the external switching inputs and outputs
Connect the module to the power supply
After finishing the electrical installation, commission and configure the LD-MRS, see
Chapter 6 Commissioning and configuration, Page 81

Planning the electrical installation
In general, observe the following requirements for electrical installation:
•
A supply voltage of 9 to 27 V DC, typical 12/24 V DC (function extra-low voltage in ac-
cordance with IEC 60364-4-41).
The voltage supply must provide at least 36 W power output. The device can be con-
nected to a supply by solar energy.
•
Electrical isolation of RS232 and sync:
•
If cables are long or the sensor and evaluation computer are far apart from one anoth-
er, potential differences can occur. To prevent damage, please use an RS232 isolator
on the sync inputs and outputs for electrical isolation.
•
Measuring mode:
Host computer (such as a vehicle computer) with an Ethernet interface for processing
the measurements from the LD-MRS
•
Field monitoring:
External control required for
– processing the output switching signals from the LD-MRS
– optional arming of specific evaluation instances using the switching inputs of the
LD-MRS
•
PC/laptop with Ethernet interface for temporary connection for configuration/visualiza-
tion of the measured data
•
Connection lines: see the order information in the product information "Product family
of the laser measurement sensor LD-MRS" or
.
NOTICE
Damage hazard!
The sensor must not be operated without supply voltage ground or a potential differ-
ence between data ground and supply voltage ground.
