System Start-Up and Adjustment
MCS-166/MCS-204
Once set, most MCS-166/MCS-204 adjustments
require no further attention. The exception is the
torque/span adjust which sets the maximum output
limit. Please follow the set-up and adjustment
procedure below for trouble free start-up.
Refer to Figure 14, page 19, for exact location of
adjustments and indicators.
A. Preliminary Set-Up
❑
1. Set voltage selector switch on MCS-166 for
proper input voltage range, 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 120/220-240 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 40 VAC operation when the line
selector switch is set for 240*AC, 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 the 120/240 VAC Selector
Switch and the High-Low Selector Switch
can damage the power supply and/or
control Module and void their Warranties.
❑
5. Slide power module into its 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. Slide the MCS-204 Control Module into its
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 Adjustments and Check Out
❑
1. Apply power to the Tension Control System
with the machine stationary. Check that the
“Power” indicators on both the MCS-166
and MCS-204 are illuminated.
❑
2. Set the front panel ‘Torque/Span Adjust”
potentiometer to its full CCW positioning.
❑
3. Brake-off/brake-on switch checks (optional)
❑
a. Set brake-off switch to off position and
note that the “brake” indicator is off. The
0-100% indicator may be on at this time.
❑
b. Return the brake-off switch to its normal
running position.
❑
c. Place the brake-on switch (if used) in
the brake on position and note that the
“brake” indicator is on. The 0-100%
indicator may also be on at this time.
❑
d. Return the brake-on switch to its normal
running position.
NOTE: If operation of the brake-off and brake-on
is reversed, the wiring is reversed. Refer to MCS-
166/MCS-204 wiring section for proper wiring
connections.
