5. Adjust the anti-residual output for Channel
“B” as follows if a brake is used on this
output. If no brake is used, then disregard
this portion of the start-up. Proceed to step
6.
5a. Using a digital DC Voltmeter, connect the
positive lead to terminal 3 and the
negative lead to terminal 4 of the
MCS2000-DRV2 for Channel “B” input.
5b. Adjust the Tension controller being used
to give a 0 VDC reading on the Channel
“B” input.
5c. Using a small screwdriver, rotate the
anti-residual potentiometer “B” fully
counter-clockwise so the output voltage
to the brake is zero level. Voltage can be
measured to the Channel “B” brake on
terminals 7 and 8 of the MCS2000-DRV2.
Terminal 7 is positive, and terminal 8 is
negative. Note that the “GREEN” LED for
Channel “B” is flashing at this time.
5d. Now slowly adjust the anti-residual
potentiometer “B” 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 “B”
terminals 7 and 8 as noted in 5c above, the
voltage observed should be negative at this time.
5e. Once this point is found, do not adjust
this potentiometer further or the brake can
re-engage.
5f. This completes the adjustment for the
Channel “B” anti-residual. Proceed to
step 6.
The following LED indications will be present when
anti-residual current is applied to the brake.
AR “B”

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