TESTABLE SAFETY DEVICE
The TESTABLE SAFETY DEVICE functional block
checks the status of the Inx inputs of a single or
double safety sensor, both NO and NC. Refer to the
tables below to check type of sensor and behavior.
Parameters
Input Type:
- Refer to the tables below to check type of sensor
and behaviour
Manual Reset:
If selected, enables the reset request after each acti-
vation of the device. Otherwise, enabling of the output
follows directly the conditions of the inputs.
There are two types of reset:
Manual and Monitored.
Selecting the Manual option, only transition of the signal from 0 to 1 is checked. If Monitored is selected, double
transition from 0 to 1 and return to 0 is checked.
