Menu Description
AL1
■
Yes : the level-1 alarm is used. The following menus are used to
define the settings for this alarm.
■
No : the level-1 alarm is not used.
AL1
■
Increasing : increasing alarm (e.g., for combustible or toxic gases,
etc.). A reading above the threshold will trigger the alarm.
■
Decreasing : decreasing alarm (e.g., for oxygen levels). A reading
below the threshold will trigger the alarm.
Thresh AL1 Define the threshold value to trigger the alarm (from 0-9900, in
increments that depend on the value).
Acq
■
Auto : the alarm (relay and indicator light) will be acknowledged
automatically once the measured value is less than (increasing
threshold) or greater than (decreasing threshold) the defined
threshold (
AL1 threshold ).
■
Manual : the alarm (relay and indicator light) must be
acknowledged manually once the measured value is less than
(increasing threshold) or greater than (decreasing threshold) the
defined threshold (
AL1 threshold ). The alarm will be
acknowledged using the remote control of via remote
acknowledgment (see
Reading under ANA1 configuration on
page 28).
Rel Define the relay(s) to be activated if a certain threshold is exceeded
(
AL1 threshold ):
■
None : no relay activated.
■
R1 : relay R1 activated.
■
R2 : relay R2 activated.
■
R1 & R21 : relays R1 and R2 activated.
