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.
o
6d. 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 1 and 2 of the
MCS2000-PSDRV2.
o
7.
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 “A” Channel.
Proceed to step 9.
o
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.
o
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.
o
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
flashng 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
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.
o
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 is not available as the
circuit has not reset as yet.
o
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-PSDRV2.
o
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.
o
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.
o
12. This completes the set up of the
MCS2000-DRV2 Driver.
