The following LED indications will be present
when anti-residual current is applied to the brake.
o 6. Adjust the input voltage from the tension
controller to the Channel “A” input
observing the “RED” and “GREEN” LED’s.
If a 24 volt system is being commissioned,
then only the “GREEN” LED should be
functional unless there is a problem with
the controller, brake, or wiring.
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.
o 8. If other LED indications are present,
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 if a
brake is connected to the Channel “B”
output observing the “RED” and “GREEN”
LED’s. If a 24 volt system is being
commissioned, then only the “GREEN”
LED should be functional unless there is a
problem with the controller, brake, or
wiring.
o 10. If no other indications are present on the
LED’s then the system is functioning
properly. The intensity of the “GREEN”
LED will not change with the amount of
output current being supplied to the brake.
o 11. If other LED indications are present,
proceed to the troubleshooting section on
page 17 to determine cause and
appropriate action to take.
48 Volt System
o 1. Prior to applying power double check all
wiring between Tension Control and Driver,
Driver and Brake or Brakes, and 48 Volt
Power Source and Driver.
o 2. Once connections are checked and
confirmed that all wiring is correct, turn
power on to the Power Supply and
Controller and observe “RED” and
“GREEN” LED Indicators on the Driver.
o 3. If everything is normal, then the
“GREEN” LED will be on and “RED”
LED’s will be off. Any other indication of
the “RED” and “GREEN” LED’s, refer to
the troubleshooting section, page 17 of
the manual for troubleshooting and
diagnostics
o 4. If drive is functional and no problems are
noted, then the anti-residual output to the
brake or brakes needs to be adjusted
according. Adjust the anti-residual output
for Channel “A” as follows.
o 4a. Using a digital DC Voltmeter,
connect the positive lead to
terminal 1 and the negative lead to
terminal 2 of the MCS2000-
PSDRV2 for Channel “A” input.
o 4b. Adjust the Tension controller being
used to give a 0 VDC reading on
the Channel “A” input.
o 4c. Using a small screwdriver, rotate
the anti-residual potentiometer “A”
fully counter-clockwise so the
output voltage to the brake is zero
level. Voltage can be measured to
the Channel “A” brake on terminals
5 and 6 of the MCS2000-PSDRV2.
