Airflow-IQ Start-up & Commissioning Guide
Ruskin Air Measurement Actuator (VAFB24-BAC) factory installed on TDP05K050/060
MODE OF OPERATION
The air measurement actuator is the BACNET interface and setup port for the air measurement station . The air
measurement actuator accepts an analog 0-10V signal via S2 input or a network driven CFM SETPOINT and will
modulate the damper based on measured CFM to get to desired air flow . Air flow measurement sensor is connect-
ed to Input 1 of the actuator and can represent velocity pressure or a velocity air flow measurement . Air measure-
ment is calculated based on actuator configuration and reported via the BACNET interface or analog output from the
air measurement sensor to the building automation system . Air Measurement actuator includes WEBSERVER and
can be configured using any web browser such as Internet Explorer . Analog input signal is required for stand-alone
air measurement control and monitoring when the network interface is not used . Direct Position Control is possible
via BACNET or Analog Input corresponding to Percent input .
FEATURES
Setup via integrated Web Server and Ethernet IP connection, directly to actuator .
BACNet MS/TP or IP
Fail Safe Signal Interlock T12, drives damper closed on loss of signal .
Spring open or spring close on loss of power as required for application .
Controls multiple Belimo MFT actuators – Use for Large multi-section air measurement stations or to control
return air damper or hot-deck cold-deck or face & bypass applications, equal or equal and opposite position .
