Installation - Air Disc Tension Brake
For brake installation, refer to the pneumatic
tension brake installation instructions, WC-68.
Installation - Transducer
1. Mount the transducer as described in the
transducer installation manual. The transducer
should be mounted where vibration is minimal
and as close to the brake as possible.
2. Mount the filter on the inlet side of the transducer.
3. A 1/4” teflon air line and the proper fittings will be
required to connect the output of the transducer
to the input of the brake. Install the air line, but do
not make the connection to the output of the
transducer. The connection will be made after the
transducer has been calibrated.
NoTe: If the air line is longer than 6 feet, a volume
booster may be required. Consult factory.
4. Connect the output of the filter to the input of the
transducer.
5. Assemble the proper fillings to connect the air
supply line to the filter. However, do not connect
the air line at this point.
NoTe: Apply a minimum amount of pipe compound to
male threads of the air line. Start with the third thread
back and work away from the end of the line to avoid
getting compound into the air lines.
SYSTeM WIRING
System Wiring Precautions
Contact with the electrical voltages present in the
controls covered in this manual can cause injury or
death. To avoid these consequences, make sure all
power is off during installation.
These wiring precautions will help you properly
install and wire a trouble-free system.
1. Use proper gauge wire for all circuits.
2. If possible, segregate AC and DC power
lines, transducer output lines, signal lines,
and switch wiring.
3. Shielded cable is recommended for sensor
connections and external switching
circuits.
4. Do not operate external accessories from
the MCS-166, MCS-207, or MCS-208
controls.
5. Do not use controls for purposes other
than those intended. Such use could
damage the control and void the warranty.
MCS-166/MCS-207
Refer to connection diagrams, Figure 9, page 10, for
wiring connections.
1. Wire AC input power to terminals 1, 2, and 3 of
the MCS-166 terminal block: Terminal 1 neutral,
Terminal 2 hot, Terminal 3 ground.
2. Wire DC ouptut from MCS-166 Terminal Block to
Input Power Terminals on MCS-207 as follows:
• MCS-166 DC Common Terminal 4 to MCS-207
DC Common Terminal 4
• MCS-166 (+) DC Terminal 5 of MCS-166 to (+)
Terminal 3 of MCS-207
3. Connect wiring from the transducer to Terminals 1
and 2 of the MCS-207 terminal block.
4. Sensor Wiring
Determine the direction of potentiometer shaft
rotation as viewed from the connector end of the
pivot-point sensor.
CW
a. For CW rotation, connect sensor wires as
follows: Black to Terminal 5, green to
Terminal 6, red to Terminal 7. Shield lead
should be connected to Terminal 7.
CCW
b. For CCW rotation, connect sensor wires as
follows: Red to Terminal 5, green to
Terminal 6, black to Terminal 7. Shield lead
should be connected to Terminal 7.
5. External Switch Connections (optional)
a. Anti-Drift or Integrator Switch
Connect switching circuit between
terminals 8 and 9 of MCS-207
terminal strip.
NoTe: The anti-drift input can be a limit switch which
closes based on dancer arm position or it can be a relay
circuit activated by the machine start cycle.
