Hysteresis Settings; Temperature Alarm (Ta); External Input - CARLO GAVAZZI LD30BI10BPIO Serie Manual De Instrucciones

Window mode
The switching information changes, when the measurement value passes the thresholds defined in setpoint
SP1 and setpoint SP2, with rising or falling measurement values, taking into consideration the hysteresis.

2.4.1.3. Hysteresis Settings

Range 5 ... 2000. Hysteresis unit is mm.
Hysteresis can manually be set for Single Point Mode or Window Mode for both SSC1 and SSC2
independently.
However SSC1 has an extra feature, Automatic hysteresis. Automatic hysteresis supports Single Point Mode
and Windows Mode.
Use parameter "SSC1 Hyst Mode" to choose between Manuel/Automatic hysteresis.
Note: When trimmer is selected, hysteresis is always Automatic.
Automatic hysteresis:
Automatic hysteresis will guarantee stable operation for most application.
Hysteresis is calculated with reference to SP1/SP2. Actual values can be read via parameter "SSC1 Auto
hysteresis value".
Manuel hysteresis:
For application that require a hysteresis other than the automatic, the hysteresis can be configured manually.
This features makes the sensor more versatile.
Note: Special attention to the application must be considered when choosing a hysteresis lower than the
automatic hysteresis.

2.4.1.4. Temperature alarm (TA)

The sensor constantly monitors the internal temperature. Using the temperature alarm setting it is possible to
get an alarm from the sensor if temperature thresholds are exceeded. See §2.6.5.
The temperature alarm has two separate values, one for setting maximum temperature and one for setting
minimum temperature.
It is possible to read the temperature of the sensor via the acyclic IO-Link parameter data.
NOTE!
The temperature measured by the sensor will always be higher than the ambient temperature, due to internal
heating.
The difference between ambient temperature and internal temperature is influenced by how the sensor is
installed in the application.

2.4.1.5. External input

The output 2 (SO2) can be configured as an external input allowing external signals to be fed into the
sensor, this can be from a second sensor or from a PLC or directly from machine output.
