7. If no other indications are present on the

8. If LED indications are present other than

those described above, proceed to the
troubleshooting section on page 17 to
determine cause and appropriate action to
take.

9. Adjust the input voltage from the tension

controller to the Channel “B” 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.

9a. Adjust the input voltage from the tension

controller to the Channel “B” 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.

9b. 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.

9c. Reduce the input on terminals 3 and 4

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
control output to the brake can operate in
the 0 to 24 volt range, but the
overexcitation level from 24 volts to 48
volts is not available as the circuit has not
reset as yet.

9d. Once the overexcitation has reset, the

“GREEN” LED will be “ON” and the
“RED” LED will be flashing as in step 6a
above when the input voltage goes above
5 volts again at terminals 3 and 4 of the
MCS2000-DRV2.

10. If no other indications are present on the

LED’s then the system is functioning properly.
The intensity of the “GREEN” LED does not
change with the amount of output current
being supplied to the brake. This completes
the checkout of the “B” Channel. The system
is now ready for set-up of the controller.
Proceed to the controller manual to set up the
controller properly.

11. If LED indications are present other than

those described above, proceed to the
troubleshooting section on page 17 to
determine cause and appropriate action to
take.

12. This completes the set-up of the

MCS2000-DRV2 Driver.
