sitting rules of digital temperature relay TR-100 (hereinafter TR-100).
1 OPERATION AND DESCRIPTION
1.1 FUNCTION
TR-100 is designed for take measurement and control of temperature of device by 4 sensors which are may
connected by two or three wire connection scheme. Temperatures will be indicated on digital display. It is possible
to use alarm signals when some of parameters come out of user adjusted ranges. TR-100 can be use for protection
of:
Motors and generators;
Tree-phase dry-type transformers with additional thermal sensors of core or environment.
TR-100 equipped for universal adapter and therefore it can use power supply from 24 to 260V without reference
to polarity.
In the capacity of thermal sensors, TR-100 is able to use next types of transducers:
PT100 –Platinum transducer with rated resistance is 100 Ohms (0 °C);
PT1000 –Platinum transducer with rated resistance is 1000 Ohms (0 °C);
KTY83 –Silicon transducer with rated resistance is 1000 Ohms (25 °C);
KTY84 –Silicon transducer with rated resistance is 1000 Ohms (100 °C);
PTC (1, 3, 6 cascade) cold resistance of transducer is 20-250 Ohms;

2 TR-100 OPERATION AND APPLICATION
2.1 TR-100 START-UP
2.1.1 Safety
All connection must be completed only BEFORE TR-100 gets power supply.
2.1.2 Connection TR-100 must be according to picture 2.
Note:All measurement transmission cables from temperature sensors should be corresponded with next
requirements:
Made of shielded twisted-pair cable (triplet);
Cable cross must be at least 0,5mm²;
Hard connection to device clamps;
Connection route must be separated from high voltage cables and from cables make inductive load;
All cables must be in equal length.
2.1.3 Turn the power supply on and adjust, if it necessary, modes of operation in according to Table 3.
2.2 APPLICATION TR-100
When temperature of one of four sensors exceeds the alarm threshold temperature value (parameter ,
see Table 3), then with user defined time the Alarm relay will close its output contact and the appropriate
indication will be shown on the front panel of the device.
The same sequence of events will happen in case tripping threshold temperature value will be detected
( ): tripping relay will close it’s contacts and appropriate indication will appear on the front panel.

Turn Off for Alarm and Tripping detected faults will happen after the temperature detected by all sensors will
become lower than - (for Alarm fault) and - (for tripping Fault). Both these relay will return to
it’s initial cold state with simultaneous front panel indication turn Off.
2.2.1 Control and Operation
In initial state TR-100 indicates temperatures of sensors which are ON, in turns with 4 sec interval (if parameter
is adjusted as 2).
Equipment control is carried out as follows:
To changing between channels press buttons;
To check all LED indicators press
TES
T
button;
To entering in view mode press
MENU
button;
To entering in adjusting of parameter mode press and hold
MENU
button for 7 seconds.
TR-100 display (for 1 sec.) and return to initial state, unless any button has pressed for 20 seconds.
2.2.1.1 Viewing of parameters.
To viewing of parameters, press
MENU
once, LED indicator “FAULT” (pic.1 pt.3) will ON and first parameter
of Table 3 will appear on the digital display.
Use buttons for scrolling. To enter in menu item, press
MENU
button, to return to previous item, press
MENU
once again. If any buttons are in inaction for more than 20 seconds, TR-100 will return to initial mode. In viewing
mode, changing of parameters is impossible.
2.2.1.2 Changing of parameters.
To changing of parameters, press and hold
MENU
button for 7 seconds, and:
If password has set, type it. Changing of current value digit due buttons, changeover to next item
by
MENU
button. To confirm password press
ENTER
button. Cancel of password - if any buttons are inaction for more
than 20 seconds, TR-100 will return to initial mode.

-5 -
NOVATEK-ELECTRO TR-100
If entered password is correct, then LED indicator “ALARM” (pic.1 pt.2) will ON and first parameter of Table 3
will appear on the digital display.
If entered password is NOT correct, then TR-100 will return to initial mode.
If is set as “000”, then password checking will NOT affected, LED indicator “ALARM” (pic.1 pt.2) will
ON and first parameter of Table 3 will appear on digital display.
Scrolling of parameters due buttons, to enter in menu item, press
MENU
button, to change value use
button, to confirm adjusted parameters and to return to menu press
ENTER
button. Exit from menu without sa-
ving due
MENU
button. If any buttons are in inaction for more than 20 seconds, TR-100 will return to initial mode.
2.2.2 Restore factory defaults.
There are two ways to restore factory defaults:
Set parameter as 1 when device is in change parameters mode, and press
ENTER
button whereupon
TR-100 will be restarted with factory defaults. In this case, password WON’T be restored.
Hold both buttons as pressed and Turn the supply power ON. Keep button holding for more than 2 s,
whereupon will appear on the digital display, release buttons. Cut off power. Factory defaults will be restored
as well as password (password disable).
2.2.3 Testing ТR-100.
2.2.3.1 Testing of LED indication.
Press
TES
T
button, all LED indicators will ON for 2 sec. If at least one of them does NOT light, TR-100 is
considered faulty and requires under repair. During test of LED indication TR-100 continue normal operation.
2.2.3.2 Testing of output relays.
In TR-100 testing all relays together is provided and each relay separately, for this it is necessary:
In change parameters mode, set value of parameter according with Table 3 and press
ENTER
button,
thus on the digital display will be showed (it means testing relay stays in normally open (OFF) conditional)
and all LED indicators will be OFF.
Condition of testing relay change due single press
ENTER
button:
- Relay stays in normally open (OFF) condition;
- Relay stays in normally close (ON) condition.
Press
MENU
button to return in menu. If any buttons are in inaction for more than 20 seconds, TR-100 will return
to initial mode.
2.2.4 Usage ventilation.
TR-100 is able to control of switching on and cutting off of cooling fan, for this it is necessary to set value of
parameter as different from 0 (see Table 3):
Mode 1 –In this mode, temperature is detected due THREE sensors 1, 2 and 3. As soon as temperature of
one of sensors exceed of temperature of adjusted threshold of switching on of ventilation , ventilation relay
will ON with corresponding indication (flashing of LED indicator 4 pic.1). Cutting off of ventilation relay will occur, if
temperatures of all sensors drop below than - .
Mode 2 –The same as Mode 1, but temperature is detected due FOUR sensors 1, 2, 3 and 4.
Mode 3 –If channel 4 is ON ( = 1, see Table 3). In this mode temperature is detected due 4th sensor.
As soon as temperature of sensor exceeds temperature of adjusted threshold of switching on of ventilation ,
relay will ON with corresponding indication (flashing of LED indication 4 pic.1). Cutting off of ventilation relay will
occur, if temperature of sensor drops below than - .
NOTE: LED 4 (pic.1) is ON, when control of ventilation is ON and LED 4 is flashing, when temperature of one
of sensors exceeds temperature of adjusted threshold (see Table 3).
2.2.5 Viewing of maximal reached temperature.
In TR-100 storage of maximal reached temperature of channel is provided. To display of maximal temperature it
is necessary:

- 6 -
TR-100 NOVATEK-ELECTRO
Come into menu of viewing or changing of parameters (pt.2.2.1.1 or pt.2.2.1.2), scroll to desired parameter
( / / / , channels 1 to 4 accordingly) due buttons, press
MENU
button (enter in
parameter), to restore maximal temperature press
ENTER
button. Return to menu -
MENU
button. To restore
temperature device should stays in change parameter mode.
NOTICE: in case there is sensor malfunction than the parameter may contain not valid values.
2.2.6 System of alert conditionals
Alert and tripping relays are ON only if threshold of adjusted temperatures is reached.
Fault relay operates in normally close conditional. It is ON, when device is turned ON, and it is OFF when there
are faults of sensors or power is cut off, indication of faults is ON if there are faults of TR-100 or sensors. In case
damage of one of connected thermal sensors indicators “TRIPPING”, “ALARM”,” FAULT” (1, 2, 3 pic.1) will be fla-
shing, code of fault ( / ) will be showed on the digital display and subsequent operation depends on
adjustted parameter (see Table 3).
Kinds of faults are given in Table 2.
