7.2 Digital Inputs
The
Humi
Core
™
Pro
transmitter has two digital inputs. Different functions can be performed when the
inputs are connected and activated. The digital inputs have to be connected to a control signal of 0 volts or
10 to 24 volts DC. The following functions are available:
Measurement STOP: This stops the measurement and freezes the value last indicated. That means this
value is retained until continuation of the measurement.
Application e.g. for batch processes, temporarily no product at the sensor and
start-stop controls for collecting devices.
Filter RESET:
This resets the mean value. To form a mean value for the moisture, you have to set
a filter time at the configuration level PRODUCTS. If, however, the instantaneous
value should be indicated, the function Filter RESET is carried out.
Batch Mode:
This results in indication of the mean value of a batch.
Application e.g. for bottling plants.
A receptacle is filled with a product. Moisture measurement is activated at the start
of the filling process and deactivated after the stop. The moisture measuring de-
vice calculates the mean moisture value of the bottled product after the end of the
filling process.
Sel.:
This changes over from one product to another.
Application in the case of product change or product replacement. This also in-
cludes changes in grain size and a fundamental change in material.
IMPORTANT: After every setting in the respective screen the data must be transferred to the
Humi
Core
Pro
system using the ‘Program parameters’ button! Otherwise there is a risk of losing
the settings (see ‘Program parameters’ in Section 6.3)!
