The driving force of motor control & electronics cooling. SmartFan TachScan-9 Fan Speed Alarm P/N 030M920-F P/N 042M920-F FEATURES SmartFan TachScan-9 is a P/N 030M920-F accepts any supply voltage from 6 to 60 VDC and distributes digital fan speed alarm that power to DC fans through the same header used to sense tach pulses. monitors the tach pulses from up to P/N 042M920-F accepts any supply voltage from 10 to 75 VDC for telecom nine DC or AC fans or blowers and applications and distributes power to DC fans through the same header used to provides both individual and ORd sense tach pulses. P/N 030M92010-F accepts any supply voltage from 6 to 60 VDC and power pass/fail signals. TachScan-9 is the DC tach circuits built into AC fans compatible with any fan that Nine inputs monitor fans with any open collector or voltage sources tach pulses. provides open collector or voltage The setting of a dip switch allows fan headers to be disabled when fewer than source tach pulses. Three trigger nine fans are connected. speeds are selectable by jumper. If P/Ns 030M920-F and 030M92010-F provide an ORd alarm output plus individual outputs for each fan, which can drive logic, LEDs or remote optical the speed of any air mover falls isolators. below the trigger speed, alarm P/N 042M920-F provides and ORd output to drive two single LEDs or one bi- signals are generated. Alarm colored LED signals can drive LEDs, logic, Provides simultaneous NO and NC isolated outputs from a Dual-Pole MOS Relay which can sink up to 100 mA to drive heavy loads. optical isolators or MOS Relays. Jumper sets trigger speed to 1,000, 2,000 or 4,000 PPM. Compatible with any SmartFan speed controller. RoHS (6/6) compliant Small size of 5 X 1.5 permits mounting in small spaces within fan trays, etc. Optional fan fusing is available.

For applications requiring less than 4.0 OR (3 Wire) (5 Wire) Amps, a single pair of power and return wires should be connected to a single pair of + and pins, respectively. For applications requiring between 4.0 and 8.0 Amps, AC connect two pairs of supply power and return leads to Power both pairs of + and pins on J11 to handle the higher current. J13 Fan Connections For three wire DC fans, TachScan-9 distributes power to the fans in addition to accepting tachometer pulses from the fans. Connect the fan wires to headers J1 through J9. Fan wires are usually color coded with red for +, J11 - + black for - and white or yellow for A (alarm). Fan current at each header must not exceed 4.0 Amps. Total fan - + current through J11 must not exceed 8.0 Amps. Vs, SUPPLY VOLTAGE 030M920 AC Fan Alarm Monitoring (P/N 030M92010-F) 042M920 + OR TachScan-9 cannot distribute AC power to AC fans.

Standard TachScan-9 Using TachScan-9 with a SmartFan Speed Controller boards are shipped with the switches in the OFF position Because of the wide range of power supply voltages that may be connected to J11, TachScan-9 may be used with any DC SmartFan speed controller. The power output of Table 1: SW1 Settings the speed controller that would otherwise be connected directly to the fan load is instead connected to J11 (see To Disable Fan Header Turn On Switch Figure 2). TachScan-9 in turn distributes this power to the fans. 9 1 8 2 7 3 Supply Variable Tach SmartFan 6 4 Scan 9 Voltage Controller Voltage 5 5 Figure 2 multi-board configurations for variable fan speed control and tachometer alarm monitoring.
