SECTION 1 DESCRIPTION
1.1 GENERAL DESCRIPTION
The TI-11 dual tension indicator is a device to output and display tension measurements. It can be used
with any type of DFE tension transducer to display actual web tension on an analog or digital meter for
reference by the machine operator. It also has voltage and current outputs that are proportional to tension,
and which can be connected to tension recorders, variable speed drive systems, computers, and other
devices for tension control or display purposes. The TI-11 contains two independent tension indicator
circuits on one card. Each has its own calibration adjustments and outputs. The card is an
IEC/ANSI/IEEE type 2 plug-in unit for installation in a standard size 3U 19 inch rack.
1.2 OUTPUTS
Each tension indicator circuit has three outputs.
A. 0 to 1mA (standard) or 0 to 100mV, selectable. Usually used for a tension indicating meter.
B. 4 to 20 mA
C. 0 to +10 Vdc (standard) or 0 to -10 Vdc, selectable and adjustable for 3.5 to 12 Vdc

1.5 STANDARD FEATURES
SOME OF THESE FUNCTIONS REQUIRE CONFIGURING OR EXTERNAL WIRING. REFER TO
SECTION 3 FOR CONFIGURING AND SECTION 2 FOR WIRING.
•0 to +10 Volt dc Tension Output. Proportional to web tension. Used as an input to other control
systems, computers or data collection devices. Adjustable.
•Meter Damping. Minimizes vibration of the optional analog tension meter needle.
•Power Voltage Selection. The TI-11 Indicator is designed to operate on two ranges of AC power;
115 Volts 60/50 Hz, and 230 Volts 60/50 Hz. A switch on the circuit board selects between the two.
•4-20mA Tension Output. Used as an input to control systems, computers, or data collection devices.
•0-1mA Tension Output.Typically used for an input to a tension readout meter.
•Status Lights. Shows status of power supplies.
•Diagnostic Connector. Located on front panel. Permits inputs and outputs to be checked easily.
1.6 OPTIONS (The option code is shown in parentheses)
SOME OF THESE OPTIONAL FUNCTIONS REQUIRE CONFIGURING OR EXTERNAL WIRING.
REFER TO SECTION 3 FOR CONFIGURING AND SECTION 2 FOR WIRING.
•230 Volt Power (230V). 230 volt 50/60 Hz power input.
•Extended Range (XRE). 10Vdc excitation for transducers. Allows measurement of much lower
tension than usual. Transducers must also have the XR option. WARNING! If one tension indicator
circuit requires XR, then the other must use it too. Both circuits must use the same transducer voltage.
Both sets of transducers must have the XR option even if only one requires it for tension range.
•0-100 mV Tension Output (100MV). Alternate to the standard 0-1mA meter output.
•0 to 10 Vdc Tension Output (10V).Alternate to the standard 0-1mA meter output.
•0 to -10 Vdc Tension Output (-10V). Replaces the standard 0 to +10 Volt dc output.

•Isolation From Earth Ground (IFEG). Removal of a jumper allows the TI-11 to float at a variable
electrical potential above earth ground. The jumper disconnects the circuit- common pc board trace
from the earth-grounded pin on the electrical connector. This can eliminate ground-loop problems or
output polarity contentions between the TI-11 and devices connected to its outputs. However, if the
jumper is removed, one of the devices connected to the TI-11 outputs MUST be grounded. This will
prevent the TI-11 from floating far enough above ground potential to cause problems. If no ground
connection exists, it is possible that the transducers may short-circuit to ground at the strain gages. The
result being electrical failure of the transducers. Must apply to both indicator circuits.
1.7 ACCESSORIES
•Analog Tension Meter (AM). 1mA, 48 Ohm movement. Must be remotely installed. A separate
meter is required for each tension circuit. DFE part #722-1385.
•Nonstandard Meter Scale (NMS). Any nonstandard analog meter scale. See Specifications, page 2,
for standard scales.
•Type 5 Plug-in Adapter. Plug the TI-11 into this adapter instead of a 19 inch rack. Terminal strips for
hard-wired connections. Install the unit in your own enclosure.

2.2 INSTALLING THE CIRCUIT CARD
The TI-11 is plugged into a standard 19 inch rack having an opening 3U high by 14HP wide. The
optional plug-in adapter may also be used.
Note: The TI-11 has been tested to meet the EMC directive, and for that compliance, the unit must be
installed in a shielded enclosure and used with shielded cables (Dover cables are shielded).
