Operation
Operating temperature range is: 14°F to 104°F (–10°C to 40°C)
The EBSM motor offers various control options. Follow the correct
wiring diagram based on the control option desired.
1. Energize motor and check for proper rotation. Rotation
should match wheel rotation as noted in fans instruction
manual and rotation arrow located on fan.
2. Adjust motor speed to verify the proper motor speed
controller functionality.
Troubleshooting
Mounted Speed Control Dial
1. Check voltage to ensure the motor is receiving the correct
control input.
2. Check voltage at the remote dial. 24VAC should be present
across the 24V and COM terminals. 0-10VDC should be
present across the 0-10V and COM terminals.
3. Verify all of the connections inside the fan and make certain
that they are secure.
Fault Indication
A red LED on the control board provides fault indication. During a
fault, this LED will blink a specific number of times to identify the
fault that has occurred.
Table 2 describes these fault indications.

Maintenance
EBSM motors use brushless technology with sealed bearings so
no maintenance is required other than keeping any accumulated
debris from collecting on the motor.
