• If more than the minimum clearances are available, proportionally adjust the upstream and downstream distances. • Avoid locating the ELECTRA-flo/SD where it will be subjected to condensing moisture from a coil. • Contact Air Monitor’s Applications Engineering Department to discuss any sub-minimal installation. .75X .5X 1.5X .75X... -
Page 8: Mounting
3.4 MOUNTING 1. Determine the measurement location based upon the engineer’s plans and the ELECTRA-flo/SD’s minimum placement guidelines. 2. Note: It may be necessary to remove a portion of external duct insulation to allow the ELECTRA-flo/ SD to be securely mounted to the exterior of the duct wall. 3. -
Page 9: Power/Signal Connections
3.5 POWER/SIGNAL CONNECTIONS The ELECTRA-flo/SD provides dual analog outputs of airflow velocity (or equivalent velocity pressure) and temperature. The temperature output has a fixed full scale range of -20º F to 120º F. The velocity output can be scaled at one of four user selectable ranges. Power wiring is done at terminal strip J1 and signal wiring is done at terminal strip J2. -
Page 10: Configuration
3.6 CONFIGURATION All device configuration is done using an 8-switch DIP package labeled S1 that can be accessed by removing the enclosure cover. The protective shield over the circuit board also has a reference guide for setting all device configurations. See Figure 4. Configuration settings can be changed while the device is powered.
