WARNING: If the Manual Reset is active, a consecutive Input have to be used.
Example: Input 1 and Input 2 are used for the fuctional block, then Input 3 have to be used for the
Reset Input.
Output test: This is used to select which test output signals are to be sent to the component
contacts. This additional control permits detection and management of any short-circuits
between the lines. To enable this control, the test output signals must be configured
(amongst those available).
Test at start-up: If selected this enables the test at start-up of the external component. This
test is performed by opening the mobile guard or safety gate 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 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: If selected this activates the test to verify concurrent switching of the
signals coming from the external contacts.
Simultaneity (ms): 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.
SINGLE E-GATE (safety gate device)
SINGLE 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
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.
