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 without much
resistance. This is best if done at
core diameter.
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.
o
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.
o
5a. Using a digital DC Voltmeter,
connect the positive lead to terminal
3 and the negative lead to terminal
4 of the MCS2000-PSDRV2 for
Channel “B” input.
o
5b. Adjust the Tension controller being
used to give a 0 VDC reading on the
Channel “B” input.
o
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-PSDRV2.
Terminal 7 is positive, and terminal 8
is negative. Note that the “GREEN”
LED for channel “B” is flashing at
this time.
o
5d. Now slowly adjust the anti-residual
potentiometer “B” clockwise while
feeling the reaction on the brake.
When the optimum anti-residual

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

The following LED indications will be present when anti-residual current is applied to the brake.
This is anti-residual mode only.
