❑ g. After set-up has been completed,
the “torque/span” knob should be
removed and the hole plugged with
the insert provided.
❑ 4. Voltage source adjust
❑ a. Insure that system power is on.
❑ b. Set the external voltage source for
maximum input level.
WARNING: The maximum input level must not exceed
14.5 VDC or damage may occur to control
logic circuits.
*Applies only to “older style” units without ribbon cable
assemblies.
❑ c. Adjust the “torque/span”
potentiometer for maximum output
(24VDC) as indicated by the 0-100%
indicator illumination.
❑ d. Adjust the external voltage source
for the minimum input level to be
used.
❑ e. Set the “zero adjust” potentiometer
or zero output until the 0-100%
indicator illuminates.
❑ f. Repeat steps b through e until no
Interaction is seen between the two
adjustments.
❑ g. After set up adjustments have been
completed, the “torque/span” knob
should be removed and the hole
plugged with the insert provided.
❑ 5. Roll follower adjustment
❑ a. Insure that system power is on.
❑ b. Connect a DC voltmeter between
the wiper and DC common on the
follower potentiometer.
❑ c. Adjust the roll follower arm for a true
zero position which corresponds
to the exact center of the roll shaft.
Adjust the roll follower potentiometer
to provide a DC input reading of 0.5
VDC ±0.1 VDC.
❑ d. Remove the meter from the follower
potentiometer and connect across
the brake magnet.
❑ e. Set the roll follower arm to
correspond to the maximum roll
diameter.
❑ f. Adjust the “torque/span”
potentiometer to provide the desired
output level to the brake as indicated
by the voltmeter.
❑ g. Set the roll follower arm back to its
true zero position.
❑ h. Set the “zero adjust” potentiometer
for a zero output as indicated by the
0-100% indicator illumination.
❑ i. Repeat steps e through h until no
interaction is evident between the
two adjustments.
NOTE: At maximum roll diameter, the output of the
MCS-204 should be set for the required tension. This
may not correspond to the full output level of the
control, depending on tension, speed, and torque
available.
D. Dynamic Adjustments
❑ 1. Remove any meter connections, etc., that
were made during set-up adjustments.
❑ 2. Start system and draw web through the
machine.
❑ 3. Make any adjustment necessary to provide
the required tensions based on the type of
input used.
This completes the start-up and adjustment of the
MCS-166/MCS-204 Remote/Analog Control System.
If any difficulties are encountered that cannot be
resolved through this manual, contact your local
Warner Electric Representative or the factory.
