SAFETY REQUIREMENTS

Read the manual carefully before starting to use the control unit. Keep the instructions for future reference.

Do not open the device, touching any internal components can cause electric shock. Contact with voltage over
50 Volts can be fatal. To reduce the risk of electric shock, do not dismantle the back of the device for any reason.
Moreover its opening would void the warranty.
Before connecting the device to the power supply, make sure that all the connections are correct. Always
disconnect the unit from the supply before any cabling modification.

Any intervention on the equipment must be entrusted to a qualified repair engineer
Failure to comply with these instructions can cause damages, fires or electric shock, and possible serious

injuries!
POWER SUPPLY

The NT210 K series has UNIVERSAL power supply, i.e. it can be supplied by 24 to 240 Vac-Vdc, irrespectively of polarity
in Vdc.
Before using it, make sure the power cable is not damaged, kinked or pinched. Do not tamper with the power cable.
Never disconnect the unit by pulling the cable, avoid touching the pins. Do not carry out any connecting/disconnecting
with wet hands. To disconnect the device, do not use objects such as levers. Immediately disconnect the device if you
smell burning or see any smoke: contact technical service.

LIQUIDS
Do not expose the equipment to splashes or drops, do not position it in places with humidity exceeding 90% and never

touch with wet or humid hands during storms. If any liquid penetrates the control unit, disconnect it immediately and
contact technical service.

CLEANING
Disconnect the power cable before cleaning the control unit, use a dry cloth to dust it, without any solvent or detergents,

and compressed air.

OBJECTS

Never insert any objects into the cracks of the control unit. If this happens, disconnect the control unit and
contact an engineer.

USE RESERVED TO QUALIFIED PERSONNEL

The purchased goods are a sophisticated electronic device that is totally unsuitable to be used by non-qualified
personnel. Any intervention must be carried out by a specialist engineer.

ACCESSORIES
The use of non-original accessories or spare parts might damage the unit and endanger users' safety. In the event of

faults, contact technical service.

LOCATION

Install the control unit indoors, in a place protected from water splashes and sun rays. Do not place near heat sources
exceeding the parameters stated in this manual. Position on a stable surface, far from any possible vibrations. Position
the unit as far as possible from any intense magnetic fields.

REPAIRS
Do not open the control unit. For any fault, always use qualified personnel. The opening of the control unit and/or the

NOTE: The sensor stem is inserted 10cm inside of the transformer, the TPL503 must not interfere with other internal
elements; In addition w e suggest always to respect the safety distance between the sensor and the live parts of the
monitored machine .

INTRODUCTION
The TPL503 sensor is fitted on the transformer cover in oil sealed box with integral filling.

The installation method is described below just for information purposes; the installer is fully responsible for the
installation.

INSTALLATION PRECAUTIONS
The transformer must be disconnected.

The transformer dielectric fluid must be at ambient temperature (about 20°C).
The level of dielectric fluid must be slightly below the transformer cover.
The TPL503 hole on the transformer must be open .
The installing area of the sensor must be free from welding or painting residue and perfectly clean.
The cork- rubber gasket, TPL base, must adhere fully to the support surface (note: replace the gasket every time it is
removed to the TPL base)

NECESSARY TOOLS
A 13x13mm spanner

A 5mm Allen wrench (inbus)

NT210 K

STEP BY STEP DESCRIPTION pictures on page 8.

NOTE: Bolts and washers for securing the sensor are not supplied by Tecsystem.

1) Following the suitably sized hole centering on the transformer fixing pins: insert the cork rubber (1) and mounting the
TPL503 base (2) into the appropriate hole in the transformer cover.

2) Insert the 4 washers (3) in the fixing pins.

3) Insert the bolts (3) onto the fixing pins and screw them in, use the 13x13 spanner, tighten but without straining

(strength recommended 8 Nm).

4) Check that the air release tap (5) is OFF.

5) Filling/Finish to fill the transformer.

6) Insert OR ring on the TPL503 base and tightening the TPL503 sensor (4) immediately over the base to its end.

7) Remove the plug on the air release tap (6), use the 5mm Allen wrench (tighten but without straining).

8) Remove the protection cap on the data / supply connector.

9) Connect the data / supply cable (7), tighten the connector manually (TPL503 connection on page 15).

10) Open the release tap (6), position ON, until the oil shows no air bubbles (sensor air bleeding), turn the tap to the OFF

position. Repeat the operation until all the air is released.
Attention: bleeding must be carried out taking into consideration the transformer operating conditions, with the

transformer switched off and a temperature of about 20°C (or ambient); the installer or maintenance engineer takes full
responsibility for this operation.

11) Insert the tap plug (6) and screw fully in, using the 5mm Allen wrench.

12) Zero the pressure sensor, see page 16.

13) With the transformer switched off, checking the values displayed by the control unit:

Temperature (ambient) - Pressure (000) - Level (full)

14) Mark the closing TPL503 sensor (4) with a label.

NOTES ON THE ASSEMBLY
The installation of the sensor must be carried out by a specialized engineer following the above procedure carefully.
For a correctly working of the system, the oil level must be in line with the release tap (6).
The end of the stem (temperature measurement) is placed 10cm below the transformer cover.
Before starting the transformer, always check the bolts are tightened and bleed the air.
The bolts loosening or the presence of air in the system might cause malfunctioning.
The presence of air bubbles might affect the level reading, therefore it is necessary to check there is no air in the system.
Filling or topping up the oil must be done with the transformer switched off and cold (ambient temperature about 20°C).
