Warranty
viii
V6.70 20131017
All new products sold to customers are warranted against defects in design, materials, and
workmanship for the life of their use to the original end user. If it is determined that the new
product defect is covered under thi
s warranty, Advanced Power Technologies, LLC (the
“Company”) will repair, replace, or substitute an identical unit at its own discretion to the customer
at no charge. The Company requires the customer to ship the unit back to the factory for
diagnosis unde
r all circumstances. In such event, the Company may, at its own discretion, decide
to provide the customer with a substitute unit which may be sent to the customer either from the
Company’s factory or from an authorized representative or distributor from t
heir inventory. All
expenses related to the shipment of defective units back to the Company or the provision of a
substitute unit to the customer are the responsibility of the customer. This expense may include,
but is not limited to, freight, insurance, C
ustoms clearance, and duties. All expenses related to the
shipment of repaired units back to customers (or the provision of a new unit to the customer) will
be borne by the Company.
Product Upgrade Policy
From time to time, the Company makes product upgra
des to add or enhance the performance of
the products. Customers of a particular product being issued an upgrade will be notified either by
the Company directly or through its authorized representatives or distributors. Customers who
have purchased an annu
al upgrade policy will receive all upgrades during the calendar year free
of charge. Customers who did not purchase the annual upgrade policy may purchase each unit
upgrade individually. The annual upgrade policy can be purchased at any time. Regardless of
whether the upgrade policy is purchased, the Company will make reasonable efforts to notify all
customers of all available upgrades.
Equipment Repair and Warranty
Repair costs of products not covered under this warranty are paid for by customers. Custome
rs
are responsible for the cost of shipping the products to the Company located at: 215 State Route
10, BLDG 2, Randolph, NJ 07869, USA. All products repaired by the Company will continue to be
warranted against defects in material and workmanship for its
installed life at the original end
user.
Limitations
The Company's warranty does not extend to (A) The Company's products subject to (i) improper
installation, connection, operation, maintenance, or storage; (ii) accident, damage, abuse, or
misuse; (iii)
abnormal or unusual operating conditions or applications outside the specifications
for the product; (iv) a purpose or application in any way different from that for which the products
were designed; (v) repairs conducted by persons other than the Company
employees or an
authorized representative or distributor; or (vi) modifications made to the product by the customer
or end user, (B) Equipment and products not manufactured by the Company. Such equipment
and products may be covered by a warranty issued by
the respective manufacturer. This warranty
is in lieu of any other warranties, express or implied, including without limitation, any warranty of
merchantability or fitness for a particular purpose, and is in lieu of any and all other obligations or

INTROD
UCTION
The TTC
-
1000, 3 Probe Transformer Temperature Controller is a mission
specific programmable controller that measures up to three different probe
temperatures
and
one
calculated winding temperature. The user can program
four (4)
or
s
ix (6) independen
t hardware outputs based on the state of pre
-
programmed temperature set points, time set points, load set points or the
outputs themselves. The controller can measure any of the three probes to an
accuracy of ± 1 ºC and does not require calibration. Calcul
ated winding
temperature is based on the methods of ANSI C57.91 and uses measured top oil
temperature and load current.
The outputs can be used to:

Control cooling fans and pumps.

Provide high temperature, LTC condition, and cooling system performance
ala
rms.

Provide a trip output.

Send temperature, load and status
to a master via DNP3.0
or MODBUS
The TTC
-
1000 is substation hardened and designed to operate over a wide
temperature range of
–
50
to 85 ºC suitable for installation in outdoor cabinets.
The TTC
-
1000 contains many features including:

Measures temperature from
-
35 to 160 ºC.

Does not require calibration.

Up to three optional
0
-
1 or 4
-
20 mA analog outputs.

Up to three temperature probes.

Optional aux CT input for calculated winding temperatures.

P
atented Load Pickup Cooling
™
set points for early activation of cooling
based on sudden increases in load.

Comprehensive Patented Dual Algorithm LTC Condition Monitoring
™
for the
detection of both slowly and quickly evolving problems.

Universal probe kit i
ncludes thermo well fitting adapters and probe sleeves.

Optional magnetic mount temperature probe
(for
when a thermo well is not
available
)
.

Reports Min and
Max Temperatures, time stamped with date and time.

2
V6.70 20131017

Data logging.

Periodic exercise of cooling fans.

Automatic swapping of lead and lag fan banks.

Four independent temperature set points per probe.

Redundant top oil capable. Operates on secondary top oil probe if one fails.

4
or
6
scheme logic programmable form C rel
ay outputs, all trip duty rated.

Dedic
ated form “C” programmable alarm relay.

Remote/Local
C
omm
s
through RS
-
232, no special software required.

Flash memory for convenient firmware upgrades.

Same unit operates from 38 to
290
VDC or 120VAC and is immune to
reversal of battery voltage polarity.

Av
ailable in either compact panel mount or a 304 Stainless Steel NEMA 4X
enclosure.

Optional DNP3.0 Level 1 communications for reading analogs plus status
and remotely commanding cooling via RS
-
485 wired connection or Multi
-
Mode Fiber
Optics. V
-
Pin fiber ava
ilable.
Status available over MODBUS as
well.

Up to 14
optional optically isolated inputs for reporting status from liquid level
or sudden pressure alarms over DNP3.0
or MODBUS
, or for selective
blocking of outputs.

Each TTC
-
1000 is burnt
-
in for a total o
f 48 hours prior to shipping and comes
with a lifetime warranty.

INSTALLATION and CONNECTIONS
The fo
llowing section gives information on hookup of power, temperature probes,
split core CT, outputs, optically isolated inputs, analog outputs along with
connections to RS232 and RS485 or fiber optics for DNP3.0 or MODBUS
communications.
There are two mountin
g configurations available. Panel Mounts are intended for
installation inside the transformer control cabinet and NEMA 4X for mounting
either inside or outside the control cabinet.
