Output test
: This is used to select which test output signals are to be sent to the emergency stop
pushbutton. This additional test makes it possible to detect and manage any short-circuits between
the lines. There is a choice of 4 possible test output signals, Test Output 1 ÷ Test Output 4.
Test at start-up
: If selected this enables the test at start-up of the external component (emergency
stop). This test is performed by pressing and releasing the pushbutton 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 emergency stop. 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 emergency stop.
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 emergency stop.
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.
E-GATE (safety gate device)
E-GATE function block verifies a mobile guard or
safety gate device input status. If the mobile guard or
safety gate is open, the output is 0 (FALSE).
Otherwise the output is 1 (TRUE).
Parameters
Input type
:
-
Double NC – Allows connection of components
with two NC contacts
-
Double NC/NO – Allows connection of
components with one NO contact and one NC.
Enable 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.
