Safety
The TMS Transformer Meter System is designed for use on transformers where the
voltage is between 100 to 277 VAC. All precautions appropriate for the line voltage
should be taken. For safety purposes, the entire sensor assembly should be considered
to be at the same potential as the conductor. The appropriate Personal Protection
Equipment must be worn.
Theory of Operation
The SensorLink TMS unit gives precise information to quickly identify inefficient
Transformer loading or power theft without the requirement of Advance Metering
Infrastructure.
The drive-by Transformer Meter is designed to capture the following parameters:
- Accumulated kilowatt hours
- Average Volts
- Average Amps
- Interval Kilowatt hours
Using secure radio protocol, the stored data is downloaded while the meters are still
deployed on the Transformer.
The radio in the Transformer Meter communicates to a USB radio transceiver that is
connected to the user’s laptop. This standards based, non-licensed wireless network
solution supports low power consumption, security, and reliability.
The TMS unit quickly installs on the energized, secondary of a pole mounted
Transformer. The meters employ a low voltage, insulation piercing connector that
securely attaches the sensor to the conductor. This voltage connection supplies the
voltage measurement and the power to operate the TMS unit.
Steelhead Software is used for the setup, download, and review of the recorded
data. Data may also be saved to a .csv file for review in other software programs.

Cleaning
Clean the TMS unit by wiping with a small amount of alcohol on a rag.
Transporting
Package contains Lithium ion 2032 coin cell batteries. Handle with care. When package
is damaged it can cause fire. Special procedures should be followed; inspect the
package and arrange repack by qualified persons when required. Contact SensorLink
at: +360-595-1000.
Radio Information
FCC and IC Notices
United States of America and Canada
Contains FCC ID: OUR-XBEEPRO
Contains Model XBee-PRO Radio, IC: 4214A-XBEEPRO
The/XBee-PRO® RF Module has been certified by the FCC for use with other products without
any further certification (as per FCC section 2.1091). Modifications not expressly approved by
Digi could void the user's authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures: Re-orient or relocate the receiving antenna,
Increase the separation between the equipment and receiver, Connect equipment and receiver
to outlets on different circuits, or Consult the dealer or an experienced radio/TV technician for
help.

Battery
Changing the Battery
The TMS Transformer Meter is powered by the line. Two coin cell Lithium Ion batteries
power the clock during momentary power disruptions and outages. The batteries need
to be installed prior to installing a TMS in the field. The batteries will provide clock
backup for up to 14 days of outage.
The battery compartment is under the clamp assembly on the “Line” sensor.
1. Remove the lid and clamp assembly by removing the three screws
2. Insert the two CR2032 batteries with the positive (+) side facing the clip that
holds them in place
3. Attach the lid and clamp assembly back to the sensor.
Incorrect Battery Installation
Steelhead's Battery Status will display "bad battery" when communicating to a unit
with a backward battery. Installing the batteries backwards will result in no battery
backup in the instance of an outage and a loss of the clock synchronization. Already
logged data will be lost. Any new data logged after power is restored will not have
correct time and date stamps.

Steelhead for TMS
Steelhead software allows the user to communicate, download, view, and graph
data from their Installed TMS units. In order for a laptop running Steelhead to
communicate, the TMS Unit must be installed on a powered line. The USB Radio
must be attached to the PC and within 300 feet, line-of-site, to the TMS Meter.
License Key
A License Key is required to operate Steelhead Software. A License Key is issued
once the user's company email address has been validated by SensorLink.
The standard License Key is valid for 365 days after the installation.
Contact SensorLink to issue any new License Keys.
Steelhead System Requirements
Steelhead installs on all computers running Windows XP Service Pack 3 and newer.
The computer has to be connected online to the internet for installation and activation
of the licensing key. Internet access is not necessary for any other use of the Software.
Steelhead Installation
Step 1: Insure the computer is connected to the internet
Step 2: Steelhead Installation Wizard will automatically load when the CD is placed
in the computer; select "NEXT" to proceed with the installation
Step 3: You must select "I Agree" to the licensing agreement to proceed
Step 4: To activate Steelhead, enter the License Key you received with the pre-
validated email address
Step 5: Steelhead can now be opened from the shortcut on your desktop or from
the start menu
Each sensor is individually labeled: 'LINE' and 'LINE/NEUTRAL'. The unit labeled
'LINE' must be installed on the main line, and the unit labeled 'Line/Neutral' must be
installed on the Neutral.
The unit labeled 'LINE' is identified as "A" in Steelhead. The unit labeled 'LINE/
NEUTRAL' is identified as "B" in Steelhead.
The TMS units may be installed anywhere between the transformer and the
customer's meter.
Attaching the TMS Line to Neutral:
Use the following steps to install the TMS Line-to-Neutral on a transformer:
1. Insert fresh batteries before installing the meter onto the line.
2. Place the sensor labelled 'LINE/NEUTRAL' to the neutral.
3. Loosen the clamp bolt so the clamp is open to go on the secondary conductor of
the transformer.
4. Place the sensor of the conductor with the clamp facing up. Center the
conductor on the teeth of the piercing connector.
5. Using a ½ inch socket, ratcheting box wrench, or a power screw gun, tighten the
bolt. Tighten the bolt so the sensor remains on the conductor with the clamp facing
up.
6. The shear head nut will break away at 38 in-lbs of torque. This insures the
insulation is pierced and the clamp assembly is protected from over tightening.
7. Place the 'LINE' sensor on the conductor to be measured and repeat the
processes two through six.
8. Three audible beeps should be heard within 15 seconds of the TMS unit being
installed. This is confirmation the meter is being powered by the line.
9. The installation is complete. Now, setup needs to be completed in Steelhead
Software.
