LumaSense Technologies LumaSMART Controller User Manual

Introduction

LumaSMART Quick Start Guide

LumaSMART is a fiber optic temperature sensing and
control system specifically designed for direct winding
temperature measurement and cooling control in high­voltage power transformers.

Unpacking and Inspection

1) Upon receipt, inspect the container in which the
LumaSMART controller is packaged prior to opening
to ensure there is no obvious damage that may have
occurred during shipping.

If there is reason to suspect that the contents were
damaged in shipping, immediately file a claim with
the carrier before contacting LumaSense.

2) Open the shipping container and carefully remove
the LumaSMART controller and related instruments.

3) Check the contents against the enclosed packing list
and inspect for signs of visible damage.

If any items are missing or if there is visible damage
to the instruments, contact:

Customer Care (Santa Clara, CA)

Email: [e-mail]
Phone: [phone] or [phone]

4) If everything is in order, save the packing material for
possible future use.

Controller

The LumaSMART controller can be mounted using one of
three methods: wall, panel, or rack mount. Refer to
section 4.2 of the manual (a copy is available on the
enclosed CD) for mounting instructions.

Connecting Fiber Optic
Extensions

Connect one of the following to the instrument to
ensure that no light enters the unit as it will cause
erroneous readings: fiber optic extensions, phosphor
plugs, or (at a minimum) the black plastic endcaps that
came with the unit. See Section 4.3 of the manual for
details on installing fiber optic extensions. A fiber optic

extension, a black cap or phosphor plug must be installed
in each of the active channels to avoid PE (Probe Error)
appearing. Ambient light will give erroneous readings if
the extensions connectors of the instrument are exposed
to it.

Installing Electrical Wiring

The table below outlines the standard configuration, as
well as the optional infrastructure communication.

Characteristic Specification

Analog Output 4 to 20 mA or 0 to 1 mA

Programmable
Relays

0, 8, or 16 Form-C

Channels (Home)

The Home screen displays a scrolling list of all the avail­able probe channels. This view displays basic informa­tion about each channel, such as temperature (or P.E. for
probe error if a signal is not available) and channel name.
All temperatures are in Celsius. Channel statuses update
every 10 seconds.

Note: The default labels are Channel 1, 2, 3, and 4. To
change these default names, go to the setup menu and
type in the nomenclature for each channel.

Protocols

The LumaSMART controller accepts nominal power of 90
to 264 VAC or 127 to 130 VDC, 47 to 63 Hz. The power
supply is internally short-circuit and overload protected.
No power cord is supplied with the LumaSMART system.
Connect an appropriate cable. The power cable must
be at least 20 AWG and UL 1061 (300V, 80C) approved.
Be sure to wire the ground to the system’s screw (shown
below).

1 Form-C

RS-485/RS-422, RS-232, Ethernet

IEC 61850, Modbus, DNP3 or ASCII

Viewing All Relays

The View All Relays screen contains a scrollable list of all
relays and their current status. A disabled status means
that the probe must be configured via the relay setup
menu. To return to the main menu, click . To return
to the previous screen, click .

Viewing All Temperatures

The View All Temperatures screen contains a condensed
list of all probes. P.E. is shown when probe is not
connected properly or broken.

The LumaSMART system requires a circuit breaker on
the power line that feeds it as a secondary line. This
circuit breaker is used to power the unit ON and OFF.
The LumaSMART system does not include any external
switches or circuit breakers. Consult local building codes
for the appropriate switch or circuit breaker to install.
Externally fuse for 200W.

See Sections 4.4.2, 4.4.3, and 4.4.4 of the technical
manual for analog output wiring, relay output wiring,
and optional communication wiring.

Starting up the Instrument

When powering up the instrument, let the instrument
run until the LumaSMART software is running.

Note: During the first minute of starting up, some relays
will be active. All relays should return to normally closed
once the software starts. During this time, please make
sure all of the fans and trips are turned off. After the
software starts, it is safe to turn the fans, trips, and
pumps on.

Viewing Signal Strength

The Sensor Channel Diagnostics screen contains a scrol­lable list of all channels and their current signal strength.

Warning: Ensure that all unused channels (channels with
no probes connected) have caps in place at all times. If an
unused channel is not capped, ambient light may affect
the temperature reading of other channels.
