  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.
