Tension Control System Installation and Operating Instructions
MCS-166/MCS-203/MCS-204
Introduction
All Warrior Electric Tension Control Systems are
comprised of an electric tension brake, a power supply
module, an electronic control module, and a sensor or
input control device.
This manual has been designed to cover the full range
of installation, start-up, operation, and maintenance
of your tension control system. System selection and
brake information can be found in Warner Electric’s
Tension Control Systems Catalog, P-771.
Power Supply
The MCS-166 Power Supply Module is designed to
operate either the MCS-203 Dancer Control or the
MCS-204 Remote/Analog Control. The MCS-166
accepts either 120 VAC or 220/240 VAC input power
and provides 26-28 VDC output power for operation of
the control modules and a brake.
Controls
The MCS-203 Dancer Control Module is a solid state
electronic control that receives a signal from a dancer
pivot-point sensor and transmits the appropriate
current to the brake to maintain a stable dancer
position. The MCS-203 is a closed loop control.
The MCS-204 Remote/Analog Control Module is
a solid state electronic control that will accept a
variety of input signals and provide an output current
proportional to the input. This system is open loop and
any change in output to the brake must be input to
the control from the signal source. The MCS-204 can
be operated by the local torque knob on its face or
remotely by external potentiometer, voltage input, or
current loop input.
The MCS-605-1 or TCS-605-5 Pivot Point Sensors
provide the dancer position signal to the MCS-
203 Dancer Control. The MCS-605-1 is coupled to
the dancer pivot when rotation is no more than 60
degrees, while the TCS-605-5 covers rotation up to
300 degrees.
