output is obtained, the brake will be
very free to rotate without much
resistance. This is best if done at
core diameter.
Note: Using a meter across the brake “B”
terminals 7 and 8 as noted in 5c above, the
voltage observed should be negative at this
time.
o 5e. Once this point is found, do not
adjust this potentiometer further or
the brake can re-engage.
o 5f. This completes the adjustment for
the Channel “B” anti-residual.
Proceed to step 6.
o 6. Adjust the input voltage from the tension
controller to the Channel “A” input
observing the “RED” and “GREEN” LED’s.
If a 48 volt system is being commissioned,
then only the “GREEN” LED should be
functional with the input voltage between
the 0 to 5 volt level, unless there is a
problem with the controller, brake, or wiring.
o 6a. Adjust the input voltage from the
tension controller to the Channel “A”
input above 5 volts while observing
the “GREEN” and “RED” LED’s. The
“GREEN” LED should be on steady
and the “RED” LED should be
flashing at a rate of approximately
30 hertz frequency with the LED on
for typically 0.5 second and off for
1.5 seconds. This indicates the
brake is operating in the overcurrent
mode and will be limited to 60
seconds.
o 6b. Allow the control to operate in this
mode for 60 seconds or more and
observe the LED’s. After the
Overexcitation circuit times out,
the “RED” LED will be flashing at a
frequency of approximately 30
hertz with the LED being “ON”
approximately 1 second and “OFF”
approximately 1 second. Measuring
the output to the brake on Terminals
5 and 6 should indicate the brake is
at 24 volts DC.
o 6c. Reduce the input on Terminals 1 and
2 to less than 5 volts DC and
observe the LED’s at this time. The
“GREEN” LED will be “ON”, and the
“RED” LED will be flashing at a
frequency of approximately 20 hertz,
with the “ON” time of approximately
0.5 second and the “OFF” time of
approximately 2.5 seconds. The

The Channel “B” is operating in the
anti-residual mode with the following indication.

The following LED indications will be present when anti-residual current is applied to the brake.
This is anti-residual mode only.
