Tree structure
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.
