The Manual PWM interface board allows accurate manual 
adjustment and monitor of fan with the GE Electric ECM 
Motor. 
The Manual interface board features a 4 digit LED 
numerical display to allow easy reading in dark spaces. 
Watch the display and set the flow index with a screwdriver 
adjust. Twenty seconds later, the display shows the 
motor RPM. Then, the display periodically alternates 
between the flow index and motor RPM. 

 

Operation 

GE ECM™ motors configured for Vspd operation are 
factory configured for external torque or airflow 
adjustment. A numerical flow index accurately adjusts the 
fan to the desired torque or airflow. The flow index is a 
number from 0-100 having a linear relationship to the 
minimum to maximum torque or airflow range specified by 
Titus. Refer to the fan specifications, data and charts to 
convert the flow index to torque or mass airflow. 
The Manual PWM interface board allows local on/off and 
fan airflow adjustment. Rotating a single screwdriver 
adjuster changes the variable output signal to the motor 
from off to full output. While rotating the adjuster, a 
numerical flow index is locked on the illuminated 
numerical display. After adjustment, the display 
shows fan RPM. 

 

 

The remote interface allows industry standard 0-10Vdc 
automation signals to adjust and monitor General Electric’s 
ECM Motor. 
The interface board provides remote adjustment of the 
ECM output from 0% to 100% of the programmed control 
range. A signal lamp on the control continuously flashes 
out the flow index

. Instruments are not required to read 

the flow index. A 0-10Vdc signal connects RPM to the 
automation control. Jumpers allow the Interface to be 
configured for 0-10Vdc automation signal, 2-10Vdc 
automation signal, and manual/override control. The 
interface can also be used for stand-alone manual control. 

 

The green lamp continuously indicates the flow index. After 
a pause, the lamp flashes out the tens digit, then the units 
digit of a number between 1 and 99. Long flashes 
represent the tens digit, and short flashes represent the 
units digit. For example, a flow index of 23 flashes two 
longs, then three shorts. 
Two extra long flashes indicate a flow index of 0. An extra 
long flash and ten short flashes indicates a flow index of 
100. The lamp flashes the signal that was present when 
the flash sequence started. 
Turning Adjust controls the ECM motor to the manually 
adjusted setting. The manual setting has authority for 15 
minutes. Set the unit to full heating (maximum 
induction). Adjust and set remote balancing dampers, if 
present. 
Adjust the speed control to deliver the required CFM by 
measuring air quantity at the room outlets.
