SECTION 1 DESCRIPTION
1.0 GENERAL DESCRIPTION
The SteadyWeb tension controller automatically maintains tension of any continuous material at the
value selected by the machine operator. It consists of three basic functions:
The first function is performed by the tension amplifier. It supports all of Dover Flexo Electronics
tension transducers. (The transducers measure the actual tension in the web). It includes a regulated
power supply to excite the transducers, an amplifier to boost the transducer output signal, and a
calibration circuit to adjust the tension readout to display actual tension.
The second function is the tension regulator. It compares the output signal from the transducers with
the signal from the AUTO Set potentiometer on the front of the SteadyWeb enclosure. If there is a
difference, the regulator will either increase or decrease tension to equalize them. The tension
amplifier and the tension regulator are both located on the Control board. (See Figure 1)
The third function is performed by the output module. It accepts the output from the tension regulator
and actuates a brake, clutch, or variable speed drive system which actually creates the tension in the
web.
1.1 OUTPUT MODULES, VERSION OF CONTROLLER
Three output modules are available for the SteadyWeb controller.
A) Pneumatic output module. This is used to actuate any air operated brake or clutch. It includes a
servo valve, a pressure regulator, and an air filter. These items are fitted together into a compact
assembly which is normally installed inside the controller enclosure or optionally located remotely.
The output range is .5 to 75 psi. SteadyWeb controllers having this module are designated
"Version 12P".
B) High Voltage output module. This module uses SCR's to produce a variable voltage of up to 90
volts DC to operate any electric brake or clutch, including eddy current clutches. 45 volt and 24 volt
outputs are optional. This module is also known as the VOUT Card. SteadyWeb controllers having
this output module are designated "Version 12V".
C)0 to 10 Volt DC compensated output module. This module is in the form of a 16 pin DIP Integrated
Circuit that plugs into the Power board near the top center. It is designated U203. See Figure 17.
This output is used to control DC drives or other variable speed drive systems, usually in
intermediate tension zones. This output is isolated from ground to make it compatible with all
drives. SteadyWeb controllers having this output are designated "Version 12D".
All SteadyWeb controllers may be easily converted from one output to another if desired. There are
five locations for plug-in cards for optional features, three on the Control board and two on the
Power board. See Figures 16, 17.
