System Start-Up and Adjustment
MCS-166/MCS-203
Once set, most MCS-166/MCS-203 adjustments
should require no further attention. Exceptions are the
“Dancer Position” and “Gain” controls on the MCS-
203 front panel. The following start-up and adjustment
procedure will provide a stable operating system.
Refer to Figure 13, page 16, for the exact location of
internal adjustment potentiometers.
A. Preliminary Set-Up
❑
1. Set voltage selector switch on MCS-166
for proper input voltage range. This will be
either 120 VAC or 220/240 VAC.
NOTE: An additional switch has been added to the
MCS-166 for selecting 220 or 240 VAC operation. This
switch is labeled Low-High. For older style units with
a single 20/220-240 VAC selector switch, proceed to
step 5 below.
❑
2. Set the Low-High Switch as follows:
❑
a. For 120 VAC, set to High Position.
❑
b. For 240 VAC, set to High Position.
❑
c. For 220 VAC, set to Low Position.
NOTE: The Low-High switch is used primarily for
selecting 220 or 240 VAC operation when the line
selector switch is set for 240 VAC, but it can also be
used if low line input voltage exists.
❑
3. Low line input: For 108 VAC input when set
on 120 VAC or 198 VAC input when set on
240 VAC, set the Low-High switch to the
Low position.
❑
4. High line input: For 132 VAC input when set
on 120 VAC or for 268 VAC input when set
for 240 VAC, set the Low-High switch to
the High Position.
CAUTION: lmproperly setting the120/240VAC
Selector Switch and the High-Low
Selector Switch can damage the power
supply and/or control Module and void
their Warranties.
❑
5. Slide the power module into the housing
and secure with the two captive fasteners
on the faceplate.
CAUTION: (OLD STYLE BACK BOARDS ONLY)
The connectors must mate properly
when inserting the control modules into
the housings. If the module does not
slide in smoothly, gently rock the module
from side to side until the connectors
mate, but do not apply excessive force.
(NEW STYLE UNITS WITH RIBBON
CABLES)
Pull the ribbon cable forward so that the
connector end is in front of the housing
assembly. Fasten the ribbon cable
connector to the pin connector on the
control module. Pin 1 (Red Tracer) on the
ribbon cable must connect to pin 1 on
the control module as shown. This “Red
Tracer” will ALWAYS be toward the top
of the control.
❑
6 Set the “Dancer Position* to its midpoint
range and the “Gain” to “5” on the MCS-
203 faceplate.
❑
7. Set the internal adjustments per Figure 13,
page 16, as follows:
❑
a. Proportional gain, “R32” fully clockwise
(CW).
❑
b. Integrator gain, “R24” at 60% clockwise.
❑
c. Differentiator gain, “R16” at 75%
clockwise.
❑
d. Differentiator response switch 1 “on” and
switches 2 and 3 “off.”
❑
8. Slide the control module into the housing
and secure with the two captive fasteners
on the faceplate.
CAUTION: OLD STYLE BACK BOARDS ONLY)
The connectors must mate properly
when inserting the control modules into
the housings. If the module does not
slide in smoothly, gently rock the module
from side to side until the connectors
mate, but do not apply excessive force.
(NEW STYLE UNITS WITH RIBBON
CABLES) Pull the ribbon cable forward
so that the connector end is in front of
the housing assembly. Fasten the ribbon
cable connector to the pin connector on
the control module. Pin 1 (Red Tracer)
on the ribbon cable must connect to pin
1 on the control module as shown. This
“Red Tracer” will ALWAYS be toward the
top of the control.
B. Static Adjustment and Check Out
❑
1. Apply power to the tension control system
with the machine in a non-running or off
mode. Check that the “power” indicators
on both the MCS-166 and MCS- 203 are
illuminated.
❑
2. Move the dancer arm to the shortest web-
loop position and note that the “brake”
indicator goes “off.” Then move the dancer
to the longest web-loop position and note
that the “brake” indicator illuminates.
NOTE: If the “brake” indicator is the reverse of this,
the Pivot-Point Sensor is wired backwards. Refer to
the MCS-166/MCS-203 wiring section for correct
connections.
