3.5.1.2. EB-FLOW2 MODELS
Default: 2-10V (voltage)
Optional Settings: 0-5V, 0-10V, 1-5V (voltage)
Output signals are not isolated from the power supply. Provide an individual power transformer,
secondary not grounded, if isolation is required.
The 1-5 VDC and 2-10 VDC outputs can drive a 250 ohm and 500 ohm, respectively, 4-20 mA input
circuit.
3.5.2. Analog Output on Total System Failure [ON FAIL]
The analog output set if a total system failure is detected.
[Menu path: SETTINGS > ANALOG OUT >↓ ON FAIL]
Default: HI (set analog outputs to 100%)
Optional Settings: LO (set analog outputs to 0%)
ONFAIL=LO. The output of AO1 is set to 0%. The output of AO2, if assigned to temperature, is set to 0%.
The output of AO3 on GTx116e transmitters is set to 0%.
ONFAIL=HI. The output of AO1 is set to 100%. The output of AO2, if assigned to temperature, is set to
100%. The output of AO3 on GTx116e transmitters is set to 100%.
3.5.3. AO1 Assignment [AO1 ASGN]
The object assigned to analog output AO1.
[Menu path: SETTINGS >↓ ANALOG OUT >↓ AO1 ASGN]
3.5.3.1. SINGLE LOCATION ALL PROBE TYPES
Default: AF (average airflow of all sensor nodes)
Optional Settings: None
3.5.3.2. DUAL LOCATION ALL PROBE TYPES
Default: AF1 (average airflow of all sensor nodes connected to Location 1)
Optional Settings: F1-2 (Location - Location 2), F2-1 (Location 2 - Location 1)
Dual location transmitters with two connections use the leftmost connector when viewed from the
display side as “Location 1”. Dual location transmitters with four connectors use the leftmost two
connectors as “Location 1”. Transmitters with 8 connectors use the top four connectors relative to the
cover as “Location 1”.
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.
