When the Auto-test status is READY, and
no problems are detected with the
generator, the date and time of the next
automatic test is advanced, so that testing
is held off for at least 24 hours (see
Sensor Auto-test).
NOTE: Auto-test is never
automatically enabled or disabled
without operator intervention.
When the Auto-test status is READY and
a generator is not installed, or has a
problem (Read Error, Wrong Gas Type, or
Under-range), a message is displayed
along with a prompt to disable Auto-test.
If not selected, or if a compatible
generator or sensor is not installed within
5 minutes, a Trouble alarm occurs, at
which time the 4-20mA output is 3.6mA
(default value), and the Trouble alarm
relay is active. The Trouble alarm must
be cleared by selecting “Disable”, or by
replacing the generator.
Selecting “Disable” sets the Auto-test state to
OFF and deactivates the Trouble alarm.
When the Auto-test status is OFF and a
problem is detected with the generator
(Read Error, Wrong Gas Type, or Under-
range), the problem is displayed, but no
Trouble alarm occurs, and no operator
intervention is required. However, an
exception will be displayed when
attempting to start Auto-test, or set Auto-
test to READY.
