Confirmation Of Packed Contents - Panasonic SF4B-H12C Instruction Manual

Introduction
Before the use of this device, construct the control system that satisfies the following requirements
to secure the safety of the whole system.
To use for Category 4 or 3
● 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.
To use for Category 2
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 detected. It is possible to use an-
other type of control output (OSSD) .
