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).
Filter (ms)
: This is used to filter the signals coming from the safety light curtain. 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.
Concurrent enable
: If selected this activates the test to verify concurrent switching of the signals
coming from the safety light curtain.
Concurrent (ms)
: This is only active if the previous parameter is enabled. It defines the maximum
time (in msecs) between the switching of two different signals from the safety light curtain.
Object description
: This allows a description of the component's function to be entered. The text is
displayed in the top part of the symbol.
FOOTSWITCH (safety pedal)
The FOOTSWITCH function block verifies the
status of the inputs of a safety pedal device. If the
pedal is not pressed the output is 0 (FALSE).
Otherwise the output is 1 (TRUE).
Parameters
Input type
:
-
Single NC – Allows connection of pedals with
one NC contact
-
Single NO – Allows connection of pedals with
one NO contact.
-
Double NC – Allows connection of pedals with
two NC contacts
-
Double NC/NO – Allows connection of pedals
with one NO contact and one NC.
Enabled reset
: If selected this enables the request to reset each time the mobile guard/safety gate
is activated. 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.
