when anti-residual current is applied to the brake.
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
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.
o 5e. Once this point is found, do not
adjust this potentiometer further or
the brake can re-engage.
o 5f. This completes the adjustment for
the Channel “B” anti-residual.
Proceed to step 6.
