ENABLE (enable key)
ENABLE function block verifies a manual key device
Input status. If the key is not turned the output is 0
(FALSE). Otherwise the output is 1 (TRUE).
Parameters
Input type
-
Single NO – Allows connection of components
with two NO contacts
-
Double NO – Allows connection of components
with two NO contacts.
Enable reset
: If selected this enables the request to
reset each time the command 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.
Î
WARNING: If the Enabled Reset is active, a consecutive Input has to be used. Example:
Input 1 and Input 2 are used for the functional block, then Input 3 has to be used for the
Reset Input.
Input test
: This is used to select which test output signals are to be sent to the component
contacts. 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. 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).
