INTERLOCK
The input status of a moving safety guard or a
safety door is checked by the INTERLOCK func-
tion block. If the moving safety guard or the
safety door is opened, the OUTPUT output is "0"
(FALSE), otherwise the OUTPUT output is "1"
(TRUE).
Parameters
Input Type:
- Double NC – makes it possible to connect
components with two normally closed con-
tacts
- Double NC/NO – makes it possible to connect
components with one normally open contact
and one normally closed contact.
Connect inactive input (OUTPUT output is
"0" (FALSE)) as follows:
- NO contact to terminal that has been as-
signed to the input IN1.
- NC contact to terminal that has been as-
signed to the input IN2.
Manual Reset: If selected, a reset can be requested on every activation of the moving
safety guard or the safety door. Otherwise the activation of the output will correspond di-
rectly to the input conditions.
There are two types of reset: "Manual" and "Monitored". On the selection of the manual
reset, the system only checks the signal transition from 0 to 1. With the monitored reset
the double transition from 0 to 1 and then back to 0 is checked.
WARNING: If Manual Reset is selected, the next Input must be used. Example: If In-
put1 and Input2 are used for the function block, Input3 must be used for the reset
input.
Output Test: Using this option you can select which test output signals are to be sent to
the component contacts. Short circuits between the wires can be detected and rectified by
means of this additional check. For this purpose it is necessary to configure the test out-
put signals (from the test output signals available).
StartUp Test: If selected, the test is undertaken on switching on the external components.
This test is undertaken by opening the moving safety guard or the safety door to carry
