The Nexen TM310T/TM340 Tension Meters are designed
for web tension systems that utilize load cell based tension
sensors to measure tension and provide amplified signals
for control with auxiliary equipment and recording.

The TM310T/TM340 Tension Meter series provides
measurement display and amplification for low output
voltage tension sensors used in web processing equipment
for materials such as paper, film, textile, and rubber. The
Tension Meter features an internal calibration system to
simplify the calibration procedure and does not require the
adjustment of potentiometers or use of a multimeter in the
calibration procedure.

The TM310T/TM340 Tension Meters display the measured
tension on a five digit display. In addition to the front panel
reading, the Tension Meter provides a selectable voltage
or current control output for use with external equipment,
independent and summed tension signals for monitoring,
DC relay contacts for tension alarms, and RS-485 serial

output for monitoring.

TM310T

The TM310T Tension Meter is the DIN Rail mount version
of the Tension Meter family.

TM340

The TM340 Tension Meter is the Panel Mount version of
the Tension Meter family.

3.3 WIRING INSTALLATION GUIDELINES

This product is designed to minimize the effects of ElectroMagnetic Interference (EMI) on its operation, but as
with any electronic device, proper installation and wiring methods are necessary to ensure proper operation. By
doing so, the interference from external effects such as electrical line spikes, electrical noise, static electricity, etc.
will be minimized. The following methods outline wiring installation guidelines to protect your system:

• All input and output signal and sensor cables must be

shielded with the shields tied to earth ground at one end.
In case of very high frequency (MHz range) electrical
noise, both ends of the shield need to be tied to earth
ground.

Relay

• Keep cable length and unshielded leads as short as

possible. Think of them as antennae for noise.

R

• Use power line lters to suppress interference on the

AC voltage lines that power the unit.

Snubber

C

• Place a resistor-capacitor network (snubber) across

inductive coils such as relays and solenoids in order to
stop electrical interference at the source (See Figure

2).

• Isolate signal and sensor cables from cables carrying

AC voltages, power for high current loads or relays
and solenoids. Either relocate the signal and sensor
cables away from other cables or use grounded metal
conduits to shield them. This will reduce the potential
for noise interference between the signal and sensor
cables and the other noisy cables.

For environments that experience high levels of static electricity follow these additional guidelines:

• Remove the static charge from material carrying it. In

the case of webs that carry static charges, there are
static charge removal products available such as static
bars and ionized blowers.

Figure 3.9

Snubber applied across relay coil

• Ensure that sensors and machine frames are grounded

to earth through a low impedance path.

• Wrap grounding tinsel around sensors and cables that

are close to the source of the static electricity and
ground the tinsel to earth.

• Tie all signal and sensor cable shields directly to earth

ground without passing through the electronic device.
This will help prevent high voltage interference from
coupling into other circuits within the device.

1. Set the parameter to No. B.

2. With the sensing roller mounted on the sensor(s), ensure
that the web or any additional loading is not resting on
the roller or sensors.

3. Check and confirm that the display is not blinking. If
the display is blinking, the range of tare adjustment has
been exceeded, indicating either that the sensing roller
is not mounted correctly, or that the sensing roller is
too heavy. Verify the correct sensor type is selected
in Parameter No. 0 and verify sensor mounting.

4. Press the 8 button to begin the automatic tare
adjustment.

5. The tension display will fluctuate for several seconds
while the tare adjustment is performed, and when
complete, the indicated parameter code will change

to blink the code digit “B”, the difference between
the left and right sensor voltages exceeds the
limit for the selected sensor type. It is advisable
to inspect the sensor mounting if this sensor
imbalance is unexpected. Refer to section 6.4
to disable the warning if desired.

1. Set the parameter to No. C.

2. Thread a cord through the center of the sensing roller
using the same path as the web to be measured, and hang
a known weight as shown in Figure 5.1.

3. Enter the known weight with the use of the r/s buttons,
and then press 8 .

4. The tension indicator will fluctuate for several seconds
while the automatic span adjustment is made. The
indicated parameter code will change to No D. once

6.4 SENSOR MEASUREMENT DIAGNOSTICS

For use with troubleshooting, diagnostic parameters are available to measure sensor voltage and to review the results of the
automatic tare and span adjustments. The diagnostic parameters are a special function accessed via the Sensor Selection
(Parameter No. 0), and are read only and will not make settings changes. To operate the diagnostic options listed below,
hold P to enter setup mode, and enter the code value into parameter No. 0. The available diagnostics are listed in the table
below, followed by a detailed description of the operation of each available diagnostic.

Measuring Sensor Voltage with tare compensation during sensor operation:

The following procedure is used for diagnostic purposes to display the measured sensor voltage while the unit is
operating, and is not operated via setup mode. This voltage measurement is tare compensated, meaning OV will be
displayed when the tare weight is applied to the sensors. This function will only measure sensor voltage within the
calibrated measurement range. This voltage measurement function is for convenience, and is not suitable when an
accurate voltage measurement is required.

1. Press the S button to select the sensor to measure, indicated by the respective No. 1 or No. 2 indicator light.

2. Press the 8 button to display the sensor span voltage in millivolts. The selected sensor LED light will blink during
this time.
