TRBH SYSTEM
TRBH SYSTEM PRESENTATION
The TRBH SYSTEM, installed on the resin transformers, will allow thermoregulation of the single phase U-V-W of the
transformer. Activation of the ventilation system and the regulation of the air flow of the fans will be managed by the
thermometric control unit models: NT935BH-D and NT935BH-ETH.
The activation and shutdown of the ventilation system, programmable on the thermometric devices, they will be anticipated
by 10° C with respect to the FAN1 ON threshold (programmed on CH1-CH2-CH3): ON speed S1 and OFF speed S0,
maximum speed S10 will reach at the threshold value of FAN1 ON.
E.g. threshold programming FAN1 ON 70°C
•Activation of ventilation system TRBH ON 61°C, speed (rpm) fan S1.
•Switch off ventilation system TRBH ON 60°C, speed (rpm) fan S0
The speed regulation (rpm) on the fans is divided into 10 steps in relation to the temperature detected on the CHF channel
and to the FAN 1 ON value.
E.g. programming of the threshold FAN1 ON 70°C, the fan speed will progressively increase in relation to the temperature
detected on the individual channel, see table example speed CH1.

NOTE: The speed regulation on the installed fans, with reference CH2 and CH3, will be managed in relation to the
temperature increase on the relative channel (selections B2-M3 and B1-M3).
The TRBH system will introduce the following advantages into your system:
•Containment of thermal and mechanical shock
•Stress reduction of the ventilation system
•Reduction in ventilation system consumption
•Reduction of noise emitted by the fans on average
•Motor fault identification and signalling
•Fan speed regulation
•Custom configuration of the ventilation system
•Fan protection for ambient overheating
In relation to the number of fans installed, the TRBH system provides for the possibility of programming the number of
connected bars (B1 - B2) and the number of fans on the single bar using the thermometric control unit.

TRBH SYSTEM CONFIGURATION SELECTION
The customised configuration of the ventilation system provides for the possibility of programming, by means of the
NT935BH temperature control unit, the number of bars connected (B1 - B2) and the number of fans on the single bar. The
following configurations BARS - FANS can be selected:
1) B1-M1/1 bar (B1) 1 fan (M1) connected
HOT speed regulation reference channel (the hottest channel of CH1-CH2-CH3)
2) B1-M2/1 bar (B1) 2 fans connected (M1-M2)
Reference channel for HOT speed regulation (the hottest channel of CH1-CH2-CH3)
3) B1-M3/1 bar (B1) 3 fans connected (M1-M2-M3)
Single speed regulation reference channel CH1 (M1) CH2 (M2) CH3 (M3)
4) B2-M1/2 bars (B1-B2) 2 fans connected (M1-M6)
Reference channel for HOT speed regulation (the hottest channel of CH1-CH2-CH3)
5) B2-M2/2 bars (B1-B2) 4 connected fans (M1-M2-M5-M6)
Reference channel for HOT speed regulation (the hottest channel of CH1-CH2-CH3)
6) B2-M3/2 bars (B1-B2) 6 fans connected (M1-M2-M3-M4-M5-M6)
Reference channel for single speed regulation CH1 (M1-M6) CH2 (M2-M5) CH3 (M3-M6)
NOTE: the fan speed adjustment (rpm), with sections other than B1-M3 and B2-M3, is managed with HOT reference
channel or the hottest channel of CH1-CH2-CH3.
In order to avoid malfunction signals, it is advisable to make the TRBH system connections respecting the selected
configuration, see control box - fans connections from page 15.
E.g. B1-1 = 1 bar B1 (only control box B1) and 1 fan connected M1 (only fan M1 connected).
Make the connections between the control unit and box (B1) and between the box (B1) and the M1 fan.
ASSEMBLY NOTES
Fix the fans on the bar using the dedicated holes on the back. Do not modify the fan fixing holes.
During fan movement, avoid deforming the impeller fins. Never change the position of the motor.
If the fan/bar is mounted on a transformer the fan's working position must
respect the safety distance indicated in the manual of the transformer on which you are installing the fan. The fan must be
positioned in a horizontal plane; always check, with the help of a spirit level, that the fan is positioned correctly.
The maximum level of vibration permitted is 60Hz.
ENVIRONMENTAL CONDITIONS OF USE
Absence of fine dust.
Absence of flammable or corrosive gases.
Relative humidity: 90% non-condensing (for short periods).
NB: maximum temperature as prescribed by the IEC 60076-11 standard.
Avoid installing it in a marine environment, except after specific treatment of the metal parts.
NOTE: failure to comply with the assembly notes and any use in critical environmental conditions
such as: long periods of standstill, high humidity, high temperatures, excessive dust and excessive vibration,
can hasten deterioration of the mechanical parts of the fans.
MAINTENANCE
In order to maintain the efficiency of the fans, periodically perform (every 6 months) a cleaning intervention on them, using
only compressed air. Do not use lubricants or greases of any kind.
Prolonged shutdown of the fan could be the cause of faults. The installation of the fans combined with the Tecsystem
thermometric control units avoids any prolonged stops. Enabling the HFN function present in the Tecsystem control units
it is possible to program activation cycles of the fans from 1 to 200 hours, recommended setting every 24 hours (for further
information on the HFN function, check the manual of the control unit purchased).
NOTE: Periodic maintenance and activation of the HFN will contribute to extending the efficiency of the fans.
Maintenance work on the fans must be programmed according to the environmental conditions in which they
operate.

NOTES: DIGITAL SIGNAL CONNECTIONS
All signal transport cables, components of the TRBH system (connections between: temperature control unit, control box
(B1), control Box (B2) and fans), must strictly respect the following rules:
• be separated from those of power
• be created with shielded and cable with twisted conductors
• have a section of at least 0.25 mm²
• be firmly fixed in the terminal blocks
• have the conductors tinned or silvered
NOTE: the use of cables not complying with the above could cause possible reading anomalies. It is very
important to always bear in mind that any disturbance on the signal lines could be the cause of anomalies.
FANS TEST
Pressing the test button of the single control box, it is possible to start the fan
test.
During the fan test the control box will activate in sequence, for approximately
10 seconds on a fan, the M1 - M2 - M3 fans connected to the single bar.
The function test of the fans has the purpose of verifying the correct positioning
and wiring of the installed fans.
Connect the motor connector A, of the single fan, with the relative motor power
cable to the MOTORS POWER LINE output of the control box.
