quirements to secure the safety of the whole system.
!
To prevent the loss of the safety function due to a single fault.
Always use two types of control output (OSSD 1 / 2).
!
To prevent the loss of the safety function due to the accumulation of the faults.
Construct the control system that can stop a device if discrepancy between control
outputs (OSSD 1 / 2) is detected.
<The example of the way to detect the discrepancy of control outputs>
(Example 1)
Use the relay unit or the controller for the light curtain.
(Example 2)
Monitor of the control outputs (OSSD 1 / 2) with the safety PLC.
(Example 3)
Monitor of the contact point welding in case the safety relay is used.
If one type of control output (OSSD) is used, the auxiliary output connects to PLC to
monitor the operation of this device, and construct the control system that can stop a
device if discrepancy between the control output (OSSD) and the auxiliary output is de-
tected. It is possible to use another type of control output (OSSD) .
