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 pressing and releasing the footswitch 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).
CERTUS Installation Manual
Manual reset: If selected this enables the request to reset each time the safety pedal 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.
