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.
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.
LOCK FEEDBACK
The function block LOCK FEEDBACK verifies the
lock status of the guard lock device for mobile
guard or safety gate. In the case where the
inputs indicate that the guard is locked the
Output will be 1 (TRUE). Otherwise the output
is 0 (FALSE).
Parameters
Input type
- Single NC – Allows connection of
components with one NC contact;
- Double NC – Allows connection of
components with two NC contacts.
- Double NC/NO – Allows connection of components with one NO contact and one NC.

With inactive input (guard unlocked), connect:
- Contact NO to terminal corresponding to IN1
- Contact NC to terminal corresponding to IN2.

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_NC or Double NC/NO Input type): If selected this
activates the test to verify concurrent switching of the signals coming from the external
contacts.
