We will use two blocks, Block 1 and Block 2.

The blocks should be the same in position and size.
For the COMP LIMIT in Block 1, select Upper.
For the COMP LIMIT in Block 2, select Lower.
Set COMP COND's NGOUT to ON (if even one block is NG, it will fail).

For OUTPUTRELAY's JUDGE OUT, select either NG output or OK output.

With the MEMORY OUT setting of OUTPUT RELAY
OUT1 is BLOCK 1 (Block 1)
OUT2 is BLOCK 2 (Block 2)
I'll leave it as is.

The BLOCK OUT terminal on the rear panel will short-circuit (create continuity with COM) when it is deemed OK.
If the limit is exceeded, BLOCK OUTPUT 1 will be OFF and BLOCK OUTPUT 2 will be ON (short).
When the value falls below the lower limit, BLOCK OUTPUT 1 turns ON (short) and BLOCK OUTPUT 2 turns OFF.

Check STATUS OUT, and if it's judged as NG, check BLOCK OUT 1 and 2.
I will check which one is causing the problem.
