TRBH
SYSTEM
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.
B1 bar motor power supply
After making all the connections of the individual fans, connect the 230Vac 50/60Hz fan lines
to the
MOTORS POWER SUPPLY
input
of both control boxes (B1-B2)
.
Connect the B motor connector of the single fan, with the relative digital cable BH motor signals to the MOTORS
CONTROL LINE output of the control box.
