5. If there is a full voltage signal,

and if the ground wire is

properly connected, check the

voltage at the Fan Card. Be

sure that you have 18-28.5

VAC at the 24 VAC terminals. If

you do not have voltage at this

point, check the transformer

and/or 24 VAC control voltage.

7. Check between "COM" and

"PWM" (0-100% duty cycle).

Depending on the input signal, it

should be a modulating voltage

between 0 and 24 VDC. (A 0

PWM signal will turn the motor

off). Turn the potentiometer to

check this. If you do not have

the proper voltage at this point,

change the Fan Card.

8. If all the voltages check out, it is

possible that the pins may not

be connecting properly and it

may be a good idea to recheck

them at the plug near the motor.

If there is a voltage discrepancy

anywhere else, each source

should be verified for proper

voltage readings. Plug both

cables back into the motor, turn

on the power and wait for the

motor to start.

TROUBLESHOOTING IN AUTO/

DYNAMIC "0-10VDC" MODE

1. Confirm the jumper on the

Fan Card is in the "0-10VDC"

position for dynamic fan speed

control via the unit controller

signal (BAS).

2. Check to verify that the unit

controller leads are properly

connected to the Auto Input

Signal terminal "+" & "-" at the

2 or 4 pin terminal dependent

on model. Ensure that an

analog signal from "0-10

VDC" is present at the "+" &

"-" terminals at the Fan Card.

Correct connections or verify

operation of controller, correct

where needed. If "0-10VDC"

signal is present at Fan Card

move to step 3.

Check steps 2 – 8 in
