3.5.6.4.3. AO1 UM = inWG [Pa]
Default: 1.50 (iWG) [300 (Pa)]
Optional Settings: 0.05 to 5.00 (iWG) [10 to 1250 (Pa)]
3.5.6.5. ALL PROBE TYPES
Some B.A.S. application controllers use “span” rather than minimum- and full-scales. The span is
equal to the full-scale – minimum scale and the offset is equal to the minimum scale.
EBTRON airflow measurement accuracy is percent of reading. Decreasing the full scale does not
improve measurement accuracy. Today’s application controllers generally have sufficient accuracy
and input resolution to use the default output scaling of the transmitters.
3.5.7. AO2 Assignment [AO2 ASGN]
The object assigned to analog output AO2.

3.5.7.1. SINGLE LOCATION -P, -T, -U AND ALL -B PROBE TYPES
Default: TEMP (temperature)
Optional Settings: ALRM (airflow alarm) or TRBL (system trouble alarm)
See “Alarm Settings” for more information on configuring built-in notification alarms.
3.5.7.2. SINGLE LOCATION -F PROBE TYPE
Default: TEMP (temperature)
Optional Settings: ALRM (airflow alarm), FA (fan alarm, FAN TYPE=ARRAY) or TRBL (system trouble alarm)
See “Alarm Settings” for more information on configuring built-in notification alarms.
FAN TYPE is selected using the ARRAY WIZARD. See “Fan Alarm Settings” for more information on
configuring the fan alarm.
3.5.7.3. DUAL LOCATION -P, -T, -U AND -F PROBE TYPES
Default: AF2 (Location 2)
Optional Settings: F1-2 (Location 1 - Location 2), F2-1 (Location 2 - Location 1)
Dual location transmitters with two connections use the rightmost connector when viewed from the
display side as “Location 2”. Dual location transmitters with four connectors use the rightmost two
connectors as “Location 2”. Transmitters with 8 connectors use the bottom four connectors as
“Location 2”.
Differential airflow is generally used in volumetric airflow units (i.e. ∆CFM [L/s]). Set the units of
measure for AO1 UM and AO2 UM to CFM [L/s] to output the differential airflow as volumetric airflow.
