MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC

Filter (ms): This is used to filter the signals coming from the external contacts. The filter
can be configured to between 3 and 250 ms and eliminates any bouncing on the contacts.
The length of the filter affects the calculation of the unit's total response time.
With Simultaneity (only with Double NO Input type): If selected this activates the test to
verify concurrent switching of the signals coming from the external contacts.
Simultaneity (ms) (only with Double NO Input type): This is only active if the previous
parameter is enabled. It defines the maximum time (in ms) between the switching of two
different signals from the external contacts.
Enable Error Out: If selected reports a fault detected by the function block.
Item description: This allows a description of the component's function to be entered. The
text is displayed in the top part of the symbol.
ESPE (optoelectronic safety light curtain / laser scanner)
ESPE function block verifies an optoelectronic
safety light curtain (or laser scanner) inputs
state. If the area protected by the light curtain is
occupied, (light curtain outputs FALSE) the
output is 0 (FALSE). Otherwise, with the area
clear and outputs to 1 (TRUE) the output is 1
(TRUE).
Parameters
Enable reset: If selected this enables the request
to reset each time the area protected by the
safety light curtain is occupied. Otherwise,
enabling of the output directly follows the input
conditions.
There are two types of reset: Manual and Monitored. When Manual is selected the system
only verifies the signal's transition from 0 to 1. If Monitored is selected the double transition
from 0 to 1 and then back to 0 is verified.

WARNING: If the Manual Reset is active, a consecutive Input have to be used. Example:
Input 1 and Input 2 are used for the functional block, then Input 3 have to be used for
the Reset Input.
OUT TEST signals cannot be used in case of safety static output ESPE because the control
is carried out from the ESPE.
Test at start-up: If selected this enables the test at start-up of the safety light curtain. This
test is performed by occupying and clearing the area protected by the safety light curtain
to run a complete function test and enable the output. This test is only requested at
machine start-up (when the unit is switched on).
