INSTALLATION AND OPERATION
SmartFan Omni SD Digital Fan Speed Control and AlarmOperation/Installation Manual
INSTALLATION
Mounting: To minimize EMI, mount the unit on a grounded surface using a metal spacer at the mounting hole that is surrounded by a conductive pad
Sensor Selection: Choose a compatible SmartFan Sensor shown in the SmartFan catalog or at www.controlres.com/sensors.php.
OPERATION
Fan Speed vs. Sensor Temperature
The relationship between fan speed, as a percentage of full speed, and sensed temperature is shown in Figure 2. Full speed occurs at the Control Temperature (TC).
Settings
Control Temperature (J2): Use this jumper to set Control Temperature to 35°, 40°, or 45°C. Factory setting is 40°C. If the P3 sensor is used, Control Temperature settings are 74°, 80°, and 86°C.
Temperature Alarm Output (J3): An over-temperature alarm output is provided at header J3 to drive a logic circuit. Pins J3:C and J3:E are internally connected to the collector and emitter of a phototransistor, respectively. This output is intended for connection to a logic circuit.
Alarm Type: Optically Isolated Phototransistor
Trigger: 10°C above control temperature
Alarm States: Conducting (Closed), Below Trigger
Cut-Off (Open), Above Trigger
Cut-Off (Open), Un-powered State
Max. Voltage: 30 VDC
Max. Current: 1 mADC
