 Threshold inversion option (default =NO)
 Tracking option
By enabling the tracking option when the device exceeds the alarm threshold the control unit activates the
following indications:
- Output modules associated through CBE
- Active Buzzer on LCD-6000T
- Device indication on the LCD-6000T display
When the device returns to its normal status the output modules associated through CBE return idle, while
the following signalling are still active:
- Active Buzzer on LCD-6000T
- Indication of the device on the LCD-6000T display
The Reset procedure must be performed for all signallings on the LCD-6000T
The diagram in the figure shows the operation feature of a
“TEC3” device programmed with threshold inversion
option = NO.
As you can see the operation feature is to increase the
current values.
Therefore the thresholds must satisfy the following
rule:
P1< P2 < AL
It can be used for esplosive gas detection sensors

The diagram in the figure shows the operation feature of a
“TEC3” device programmed with threshold inversion
option = YES.
As you can see the operation feature is to decrease the
current values.
Therefore the thresholds must satisfy the following
