The SMART display is blank System powered off !" Check that the I/O connector is correctly plugged
in and that there is a 24 Vdc power voltage on pins
1-2.
!" Check the protection fuses

!" Press the button. The system will erase the
user settings and will load the default values.
Reload the parameters and custom settings. If the
problem persists, contact your
BTSR reseller.
!" The replacement of the system’s lithium battery
may be required
The SMART system does not

not responding. System halted, probably due to a sudden
over-voltage load.
(e.g. lightning)
!" Power off and on the system. If the problem
persists, contact your

reseller.
The display shows the

Faulty XXX Sensor or incorrectly
numbered. !" Assign again a number to the sensor XXX. If the
problem persists, replace the sensor.
!" If the problem persists, check the connection cable
of the sensor; replace it if necessary.
!" If the problem persists, assign again a number to
all the sensors.

Problems on the communications line !" Check that the sensors are correctly connected.
!" Check for locked sensors (green and red LED
simultaneously ON). Power off and on the system.
If the problem persists, replace the sensor.
!" If the problem persists, connect a set of sensors at
a time trying to isolate the problem.

If the fault is not included in the above table, please contact your local BTSR reseller, giving a
detailed description of the kind of fault and the conditions in which it occurred. In the case where the
BTSR Technical Service intervention would be required, before calling it is suggested to take note of
the code printed on the faulty sensor(s) and/or on the SMART 200 TTS terminal, as this information
will make diagnoses for the BTSR technicians easier.
Example:
Sensor Code:
TS5/D 500DD
Terminal Code: SMART 200 TSS V01S11 0302 10
