2. Lists of Parameters
* Parameters relating to PV should all be set in real numbers.
For example, use temperature values to define alarm setpoints for
temperature input.

22: FAIL output
Turns off in case of program failure, ROM
failure, RAM failure, or power failure. This
output is on during normal operation. If it
turns off, the retransmission output is set to
0%, the alarm output is set to OFF, and the
indicator stops.

manual for details on how these Alarm Type
parameters behave.
