probe becomes faulty or gets disconnected.
Out 1 Error is triggered when the analog output 1 goes in error because the set high
or low limits are exceeded.
Out 2 Error is triggered when the analog output 2 goes in error because the set high
or low limits are exceeded.
Out 3 Error is triggered when the analog output 3 goes in error because the set high
or low limits are exceeded.

any of them triggers the alarm and switches the relay RL3.
