1 Model Name SuffixSpeed-StableFree-RunningFansFans Description-01-51 No optional features: Color-coded power leads (red +, black -) with stripped Open-collector tachometer circuit, two square wave pulses per revolution, 50 per-cent duty cycle, terminated in a third lead wire. Standard lead wire color is Open-collector, non-latching, low-pass/high-fail locked rotor alarm circuit terminatedin a third lead wire. Standard lead wire color is Open-collector, low-pass/high-fail, trip-point alarm circuit terminated in a third leadwire; non-latching alarm is activated at specified low-speed threshold (70 percentof fan s nominal operating speed, standard). Standard lead wire color is Open-collector tachometer and non-latching, low-pass/high-fail locked rotor alarmcircuit terminated in a third lead wire;two square wave pulses per revolution, 50percent duty cycle, under no-fault conditions.

2 Standard lead wire color is Pulse-width modulated speed control circuit terminated in a third lead lead wire color is PWM speed control circuit (option -06 or -56) terminated in a third lead wire (stan-dard = blue) and an open-collector, tachometer (option -02 or -52) terminated in afourth lead wire (standard = yellow).-08-58 PWM speed control circuit (option -06 or -56) terminated in a third lead wire (stan-dard = blue) and an open-collector, non-latching, low-pass/high-fail locked rotoralarm circuit (option -03 or -53) terminated in a fourth lead wire (standard = yellow).-09-59 PWM speed control circuit (option -06 or -56) terminated in a third lead wire (stan-dard = blue) and an open-collector, non-latching, low-pass/high-fail, trip-point alarmcircuit (option -04 or -54) terminated in a fourth lead wire (standard = yellow).

3 -10-60 Thermal speed control circuit employs an NTC thermistor mounted on the housingof the fan;the speed control profile requires specification of low-temperature oper-ating speed (rpm), low-speed threshold ( C) and high-speed threshold ( C).-11-61 Thermal speed control circuit (option -10 or -60) and an open-collector tachometercircuit (option -02 or -52) terminated in a third lead wire (standard = yellow).-12-62 Thermal speed control circuit (option -10 or -60) and an open-collector, non-latch-ing, low-pass/high-fail locked rotor alarm circuit (option -03 or -53) terminated in athird lead wire (standard = yellow).-13-63 Thermal speed control circuit with pulse-width modulated speed control: Thermalcontrol profile, using an NTC thermistor mounted on the housing of the fan, can betuned to application requirements by PWMinput terminated in a third lead wire(standard = blue).

4 -14-64 Thermal speed control with PWM control (option -13 or -63) terminated in a thirdlead wire (standard = blue), and an open-collector, tachometer (option -02 or -52)terminated in a fourth lead wire (standard = yellow).-15-65 PWM speed control circuit (option -06 or -56) terminated in a third lead wire (stan-dard = blue) and an open-collector, non-latching, inverse (high-pass/low-fail) lockedrotor alarm circuit terminated in a fourth lead wire (standard = yellow).
