The driving force of motor control & electronics cooling. SmartFan TachScan-3 Fan Speed Alarm SmartFan TachScan-3 is a FEATURES digital fan speed alarm that P/Ns 030M320-F and 030M320R-F accept any supply voltage from 6 to 60 monitors the tach pulses from up to VDC and distribute power to DC fans through the same header used to sense tach pulses. three DC or AC fans or blowers P/Ns 030M3205-F and 030M320R4-F accept any supply voltage from 6 to 60 and provides ORd pass/fail VDC and power the DC tach circuits built into AC fans signals. TachScan-3 is compatible Three inputs monitor fans with any open collector or voltage source tach pulses with any fan that provides open P/Ns 030M320-F and 030M3205-F provide simultaneous NO and NC open collector or voltage source tach collector outputs from optical isolators which can sink up to 1.0 mA to drive logic circuits pulses. Three trigger speeds are P/Ns 030M320R-F and 030M320R4-F provide simultaneous NO and NC selectable by jumper. If the speed isolated outputs from a Dual-Pole MOS Relay which can sink up to 100 mA to of any air mover falls below the drive heavy loads trigger speed, alarm signals are Jumper sets trigger speed to 1,000, 2,000 or 4,000 PPM generated. Alarm signals can drive Can drive two single LEDs or one bi-colored LED LEDs, logic, optical isolators or Compatible with any SmartFan speed controller MOS Relays. RoHS (6/6) compliant Small size of 3.5 X 1.5 permits mounting in small spaces within fan trays, etc. SPECIFICATIONS Isolated Alarm Supply Voltage Maximum Maximum Output Part Number Fan Type Sinking Current Range Input Current Current to Any Fan 030M320-F DC 1 mA 4.0 Amps 030M320R-F DC 100 mA 4.0 Amps 4.0 Amps 6 to 60 VDC 030M3205-F AC 1 mA N/A 030M320R4-F AC 100 mA N/A H115-F Hardware Pack Note: Maximum operating temperature is 65C CONTROL RESOURCES INCORPORATED www.controlres.com 2012 (09), Page 1 of 3 AlarmsTachScan-3 - Installation & Operation INSTALLATION DC Fans AC Fan Vs + - OR (3 Wire) SUPPLY (5 Wire) J7 VOLTAGE Fan Connections For three wire DC fans operating at supply voltages between 6.0 and 60.0 VDC, TachScan-3 distributes power V2 AC Power to the fans in addition to accepting tachometer pulses from R2 Sense VB the fans. Connect the fan wires to J1, J2 and J3 using the suggested hardware, or equivalent. For applications using V1 R1 less than three fans, any of the three connectors (J1, J2, Sense VA J3) can be used to monitor tachometer signals. The fan Green wires are usually color coded with red for +, black for - and (N.C.) Red H white or yellow for A (alarm). Input current must not (N.O.) M L exceed 4.0 Amps.

AC Figure 1.0 Typical wiring diagram. Sense VB = V2 VDC fans usually have 5 wires, 2 for po wer and 3 for the tachometer pulse circuit. Connect the AC fan power leads to the rated source of por. weConnect the tachometer pulse leads (+, -, tach pulse) to J1, J2, and J3. TachScan- Tach Supply Variable SmartFan 3 distributes power to run the tachometer pulse circuits Voltage Voltage Scan 3 Controller within the fans. Apply a DC voltage as specified by the fan manufacturer for the tachometer pulse circuits at J7. Figure 2.0 Multi-board configuration for variable fan speed control and Use with a SmartFan Speed Controller tachometer alarm monitoring. Because of the wide range of power supply voltages that may be connected to J7, TachScan-3 may be used with any DC SmartFan speed controller. The power output of the speed controller that would otherwise be connected directly to the fan load is instead connected to J7. TachScan-3 in turn distributes this power to the fans.
