5 LSI System Planning
5.1
General planning information
Sensors:
You can connect up to four sensors to the LSI. All connected
sensors must be of the same type (e.g. four PLS 101-312).
These are currently types PLS 1XX-3XX, or any type for which
this is expressly permitted in the technical description.
Monitoring areas:
You can define up to eight monitoring areas. Each monitoring
area consists of a protective field and a warning field.
To define the size of the monitoring area, follow the instructions
given in the technical description of the PLS. It gives
dimensioned examples for static and dynamic applications.
For the PLS system with LSI, the minimum response time is 190
ms (except if you combine the LSI with PLS type 101-316 for
vehicle protection, in which case note that the response time of
the LSI is not programmable, but is fixed at 270 ms).
Monitoring cases:
To view the monitoring areas on the connected sensors, you can
set up to 15 monitoring cases.
At each time point a maximum of two monitoring cases may be
active at any one time (simultaneous monitoring cases).
Safety and signaling outputs:
The LSI has two independent safety output pairs OSSD (output
load per OSSD channel max. 250 mA
≤
100 nF; restart effective
from 0.2 to 5 seconds).
If necessary, you can perform contactor monitoring on any of the
safety outputs (EDM, permitted tolerance max. 200 ms).
The warning field and signalling output load is 100 mA.
Inputs:
The LSI has the following inputs:
– Four binary inputs (A to D) with a maximum of 80 ms time
difference (antivalent)
– Two incremental encoder inputs (inputs C and D)
– Two restart inputs
– Two EDM inputs (contactor monitoring)
