Reset Type There are two types of reset: “Manual” or “Monitored”. If the “Manual” option is selected, only
the signal transition from “0” to “1” is checked. In the case of the “Monitored” option, the dou-
ble transition from “0” to “1” and back to “0” is checked.

StartUp Test If this option is selected, it activates the test on startup of the electro-sensitive protective
equipment. This test requires the protection zone to be interrupted and cleared in order to
perform a complete function test and to activate the “O
UT” output. This check is only re-
quired on machine startup (when the module is switched on).
Filter (ms) The filter can be configured with a value between 3 and 250 ms and helps suppress contact
chatter. The length of the filter time affects the calculation of the response time of the safety
function.
Simultaneity (ms) Always active (parameter cannot be deselected). Defines the maximum time (in ms) that
may elapse between the commutations of the various incoming signals from the external
contacts.
Enable Error Out When this parameter is selected, an output (“E
RROR”) is made available which signals that
an error has been detected by the function block.
Item Description A 24-character text description of the function or the name can be entered here. The text is
displayed above the function block.
NOTE:
Inputs at a function block must always be used in ascending order.
Example: Input 1 and Input 2 are used for the function block, so Input 3 must be used for
the reset input.
