7) MEASURE SIGNALS TRANSPORT
All the transport cables of the Pt100 measure signals must absolutely:
be divided from the power ones
be realized with shielded cable with twisted conductors
have a section of min 0.5 mm²
be twisted if you have no shield
be firmly fixed in the terminal board
have tinned or silvered conductors
All the “T” series units have the sensors linearization with a max error of 1% v.f.s..
8) THERMOMETRIC SENSORS DIAGNOSTIC
In the event one of the thermometric sensors installed on the machine to protect is dam-
aged, the FAULT relay energizes immediately, the ALARM and TRIP LED’s of the dam-
aged channel lighten and the FAULT LED is lightening.
The screen will automatically display a message showing the fault condition:
Fcc sensor is short circuited
Foc sensor is open
9) FCD FUNCTION - DEFECTIVE SENSORS
During the unit normal operation, if the Fcd-YES function has been selected, the display will
show Fcd indicating that a sensor is damaged and the LED corresponding to the affected
channel will lighten.
The FAULT relay will energize giving a signal to the operator.
After the replacement of the damaged sensor, you can reset the alarm pushing RESET until
the display shows the message rSt.
10) TEMPERATURES DIAGNOSTIC
When one of the thermometric sensors surveys a temperature exceeding by 1°C the alarm
limit, after 4 seconds the ALARM relay will energize and the ALARM LED of the affected
channel will switch on.
The same occurs when the TRIP temperature limit is detected: the TRIP relay energizes
and the TRIP LED corresponding to the affected channel is lightening.
When the surveyed temperature declines of 1°C below the prefixed limit for the ALARM and
TRIP switching , the relays de-energize and the respective LED’s switch off.
TECSYSTEM srl has realised a special cable for the measure signal transport
with all the protection requirements according to CEI Norms: mod. CT-ES
