m³/h.

– Units of measure
If
you use one of these flow and sensor units, you only need to inform the "Sensor Factor" parameter. If none of the units available is required, you
need to calculate the
"User Factor", relating it to the "User Unit" parameter, and fill in the parameter so that
LogBox BLE
can correctly convert the
pulses to the unit required. In this case,
LogBox BLE
will co
nvert the pulses to the user unit as follows:
● User Value
= ((Count)/(Sensor Factor))*(Unit Factor)
○ It is not necessary to consider the log interval for calculations.
Figure 2 –
Digital Input
If
the user wants to visualize the production of pieces in "pieces per minute", for example, and the application has a sensor of the type PNP that,
every 30 pulses in the rising edge, computes the produced piece, the following parameters must be configured on the digital input of the device:
•
Input Type:
Puls
e Count.
•
Sensor Type:
PNP.
•
Counting Edge:
Rising.
•
Application:
Flow Rate.
•
Sensor Factor:
30 (pulses/piece).
It is necessary to select the "Average Flow by Acquisition Interval" option and, after that, fill in the following parameters:
•
Unit:
Custom.
•
Unit Factor:
60 (conversion of pieces per second to pieces per minute).
It is also possible to select the "Volume since Last Reset" opt
ion and, after that, fill in the following parameters:
•
Unit:
Custom.
•
User Factor:
1 (storage the accumulated number of pieces).
Thus,
LogBox BLE
will log, in each log interval, the number of pulses occurring within that period, and every time the data is displayed, it will turn
those pulses into the number of pieces produced per minute (custom unit of the user).
In the same example, let’s say that the log interval is 20 seconds. Thus, if the sensor gives 20 pulses per second, the
LogBox BLE
will register 400
pulses per range, displaying to the user 40 pieces per minute (((20 pulses/s)/(30 pulses/piece)) * 60 (1 min) = 40).
5.2.2 EVENT LOG
If the digital input is configured for Event Log, each selected border will cause a log in the memory, informing the event and the instant the event
occurred. This log will not be synchronized with the periodic logs, but will also respect the logs start and stop mode. Events will be logged after the
configured debounce time expires. Thus, events will be logged with the debounce time delay.
LogBox BLE
can log up to 10 events within 1
second.
5.2.3 LOGS CONTROL
You can use the digital input to start and/or pause the logs of the other input channels. Once configured as Logs Control, each border selected will
start or stop the process of in-memory logs. As in the Event Log mode, detected events will only act after the configured debounce time expires.
Thus, the start/pause of the logs will be performed with the debounce time delay.
