24 Volt System
o
1.
Prior to applying power, double check all
wiring between Tension Control and Driver,
Driver and Brake or Brakes, and 24 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
accordingly. 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.
Terminal 5 is positive, and terminal
6 is negative. Note that the
“GREEN” LED for Channel “A” is
flashing at this time.
o
4d. Now slowly adjust the anti-residual
potentiometer “A” clockwise while
feeling the reaction on the brake.
When the optimum anti-residual
output is obtained, the brake will be
very free to rotate or the armatures,
in the case of the TB’s, will feel like
they are floating away from the
magnet assembly.
Note:
Using a meter across the brake “A”
terminals 5 and 6 as noted in 4c above,
the voltage observed should be negative at
this time.
o
4e. Once this point is found, do not
adjust this potentiometer further or
the brake can re-engage.
o
4f. If a second brake is used on
Channel “B”, then proceed to step
5 otherwise this completes the
anti-residual adjustment for the “A”
Channel. Continue to step 6.
The following LED indications will be present
AR “A”

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