10 LOGICAL INPUTS
Each input can work individually in either positive or negative logic. A holding time (de-bounced time) attached to all
inputs can be configured.
10.1 Inputs assignment
Inputs can be assigned individually to one of the following functions:
Function Functioning mode
transmitter checkweigher
None ● ●
Tare ● ●
cancel tare ● ●
Zero ● ●
Transmit measurement ●
Measurement window ●
checkweigher start cycle ●
checkweigher stop cycle ●
Clear checkweigher result ●
Dynamic zero ●
Sensor input control ● ●
10.2 Inputs functions description:
10.2.1 None
Inputs have no effect.
10.2.2 Tare
Each input can be assigned to the tare function. Depending on the chosen logic (positive or negative) for the
corresponding input, tare is triggered by a falling or rising edge.
10.2.3 Cancel tare:
Depending on the chosen logic (positive or negative) for the corresponding input, cancel tare is triggered by a falling or
rising edge.
10.2.4 Zero
Each input can be assigned to the zero function. Taking zero is assigned a stability criterion configurable. Depending on
the chosen logic (positive or negative) for the corresponding input, zero acquisition is triggered by a falling or rising
edge.
A new zero is acquired only if its value is within a range

10% of maximum capacity or

2% if eNod4-C is in legal for
trade functioning mode. This new value is the useful zero value, a reset cancels it.
10.2.5 Transmit measurement
This is only possible using standard or fast SCMBus format or CANopen® protocols.
The request can apply to:
•
gross measurement.
•
net measurement.
•
factory calibrated measurements
A single measurement is transmitted per rising or falling edge (depending on the configured logic) on the input signal.
