Power Source
The TCS-200-1 series Tension Controls operates from a power source of 115 or 230 VAC, 50/60 Hz input. Primary voltage is determined by the customer's input voltage source. The control is factory set to accept 115 VAC input. Refer to the wiring section for 230 VAC input connections.
Control
The TCS-200-1 series controls are selectable voltage or current controlled power supply designed to power up to a 16 magnet Electro Disc tension brake system, Electromagnetic Particle Brakes, TB series brakes or Advanced Technology tension brakes. This control can be operated manually from the front panel or remotely via an analog voltage input, a current input, a remote pot, or a roll follower. External inputs are also provided for remote brake "off", "run", and "stop" functions, as well as front panel control of these functions.

Introduction
The Warner Electric Tension Control system is comprised of a tension brake, control module, and optional external sensor input.
This manual has been designed to cover installation, start-up, adjustment, and maintenance of your tension control system and covers the control system only. Further information on brake sizing and selection can be found in catalogs P-1234 or P-771.
The analog voltage and current inputs are electrically isolated from the main power circuitry of the control when 15-35 VDC supply is provided to maintain full isolation. If isolation is not needed, an on board 15 VDC supply is jumpered to act as a default.
Sensors
When the TCS-200-1 series controls are operated in a remote torque adjust mode, a 1,000 ohm potentiometer is required. This should be a linear type potentiometer with a rating of .5 watts, 10 percent tolerance, and a .5 percent linearity.
For roll follower input applications, a 1,000 ohm potentiometer with a rating of .5 watts, 10 percent tolerance, and .5 percent linearity is required for best performance.
Brakes
All 24 VDC tension brakes that Warner Electric offers, to a maximum of 4.25 amps, can be used with the TCS-200-1 tension control. For all 24 VDC tension brakes that require greater current capability from the control (not to exceed 5.8 amps), use a TCS-200-1H. The brake converts electrical current supplied by the control into torque, which retards material flow, maintaining the desired web tension.

Theory of Operation
When in operation, the control is powered by a standard 115/230 VAC line. The control has a transformer that converts that voltage to a level suitable for any 24 VDC brake system. The signal is rectified to DC and pulse width modulated (PWM) to the desired brake current via the TENSION ADJUST knob.
The front panel TENSION ADJUST feeds a small voltage to a comparator, which compares this signal to a triangular wave. This is where the PWM pulse is generated. This pulse is then inverted and used to drive a power circuit. The main brakes and a sense brake are then energized by the power circuit at regular intervals. From the sense brake, a growth and decay signal is converted to a voltage that can be added to the signal by setting a jumper on the inside of the cover. This signal, when selected, is used to maintain constant current to the brake. The signal must not be selected when no sense brake is connected.
The control has several options that allow for external/remote tension adjust in addition to the tension adjust pot on the front of the panel. Two such options are the remote pot or a roll follower. Another is the option for an analog input of voltage or current from a PLC or ultrasonic sensor. A special feature of the analog inputs is that they are optically isolated from the rest of the control circuitry if an external power source is used to power the isolated circuits. The isolation is needed when using a PLC or an external power supply for the ultrasonic sensor. An internal power source is also available and jumpered in as default if isolation is not necessary. The tension adjust pot on the front of the panel becomes a span adjust when any of the external control options are connected.
The control also has the capability to duplicate the front panel selector switch at a remote location. Brake "off" mode overrides the tension adjustment and provides for resetting the short circuit indicator. In the "run" mode, output operation is normal and is controlled by any of the front panel or remote tension adjust features discussed above. The brake "stop" mode provides for full output current to the brake.
The two indicators on the front of the panel are green for "power on" and red to indicate a short circuit. When a short occurs in the brake, the control disables the power circuits to prevent damage. Turn the switch to "off" to reset the short circuit indicator.
Because this is a basic tension control, no anti­residual circuits, zero adjust circuits, or other complex control circuits (found in other Warner Electric tension control systems) are included in the TCS-200-1 series controls.

o 4. Attach conduit or seal tight connectors.
The control is now ready to be wired. Refer to the wiring section of this manual for proper system wiring.
Note: If angular rotation is not adequate, insufficient output from the control is possible. In this case, a timing belt drive between the roll follower pivot-point and the sensor potentiometer may be necessary to obtain adequate angular rotation.
Brake Installation
Refer to the brake manual that is appropriate for the brake selected for its installation procedures.
External Sensor Mounting (Optional)
Options for four types of external sensor inputs are available. These consist of either an external torque adjust, roll follower input that provides a signal directly proportional to the diameter of the roll to be processed, analog voltage, or analog current input. Determine which type of external sensor will be used and proceed to the appropriate section of this manual.
Remote Torque Adjust Potentiometer (Optional)
o 1. Select an appropriate mounting location for
the external torque-adjust potentiometer.
Note: In determining this mounting location, take into consideration the routing of the wires necessary to connect the control, access for the operator, and space required by the physical size of the potentiometer.
o 2. Drill a mounting hole based on the bushing
diameter of the potentiometer selected.
o 3. Mount and secure the potentiometer.
o 2. Secure the roll follower potentiometer. This
completes the mounting for a roll follower potentiometer. Refer to the wiring section of this manual for proper control wiring.
Analog Input (Optional)
o 1. Select an appropriate mounting location for
the PLC or ultrasonic sensor.
o 2. Mount and secure the PLC or ultrasonic
sensor according to the specifications for those products.
This completes the mounting. Refer to the wiring section of this manual for proper control wiring.
System Wiring
System Wiring Precautions
The following wiring precautions will help you properly wire and install a trouble free system.
o 1. Use a proper gauge wire for all wiring.
o 2. Insure that wires are cut and stripped so that
no excess bare wire is exposed.
o 3. Segregate AC input power from control
switching and external sensor wiring (if used).
This completes the mounting for an external remote torque adjust potentiometer. Refer to the wiring section of this manual for proper control wiring.
o 4. Do not run AC power lines with DC power,
input sensor wiring, or switching wiring. Noise transients can be easily transferred, causing erratic control operation.
