1 OPERAT ION AND DESCRIP TION

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 transfor mers w ith 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 ty pes of tr ansducers:

• PT100 – Platinum tran sducer with rated resistance is 100 Ohms (0 °C);

• PT1000 – Platinum tr ansducer with rated resistance is 100 0 O hms (0 °C);

• KTY83 – Silicon transducer with rated resistance is 1000 Oh m s (25 ° C);

• KTY84 – Silicon transducer with rated resistance is 1000 Ohms (100 °C);

• PTC (1, 3, 6 cascade) cold r esist ance of transducer is 20-250 Ohms;

2.1 TR-100 START-UP

2.1.1 Safety

Table 3).

All connection must be completed only BEFORE TR-100 gets power supply.

2.1.2 Connection TR-100 mus t be according to picture 2.

Note: All measurement t r ansmission cables from temperature sensors should be corresponded wit h next
requirements:

• Made of shielded twisted-pair cable (triplet);

• Cable cross must be at least 0, 5m m²;

• Hard connection to device clamps;

• Connection route must be separated from high voltage cables a nd from cables make inductive load;

All cables must be in equa l len gt h.

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

• W hen 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 tr ipping t hreshold 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 simu ltaneous 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 carr ied out as follows:

• To changing between channels press buttons;

• To check all LED ind ic ators press

• To entering in view m ode press

• To entering in adjusting of parameter mode press and hold

• 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 param et er s .

To viewing of parameters, press 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 button, to return to previous item, press
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 para m et er s is i m possible.

2.2.1.2 Changing of parameters.

To changing of parameters, press and hold

• If password has set, type it. Changing of current value digit due

by
