• Measurement window
Only available in SCMBus/fast SCMBus protocols. Measurements are continuously transmitted at a rate defined by the
‘sampling period’ while the input is maintained at the chosen level.
• Start/Stop (batch/system)
If all the starting conditions are respected, a rising or a falling edge (according to the configured logic) on this input
causes a new totalization cycle to be started.
In batch mode and when cleared totalization at starting new cycle option is enabled, the totalization result is set to
zero at each start cycle.
If dosing cycle is running, the second edge of this command will stop the process.
• Belt running motion detection
If speed sensor is broken or if no speed sensor is connected to eNod4 device, this logical input might be assigned to
motion detection function to enable totalization function.
• Clear/Reset totalization and errors counter
Cleared totalization function can be assigned to logical input. You may clear total amount dosed and dosing errors
counter at any time. At this input activation on rising or falling edge (according to the configured logic), the main total
in weight unit x1000 and the complementary weight value are reset to zero.
Also, dosing errors counter parameter is set to zero.
• Dynamic zero
When the belt is running empty, this input activation will cause eNod4 to perform conveyor zero function by
measuring rate of flow of material.
Run the conveyor for several minutes to ensure the belt is empty and supple. The conveyor should be operating at
normal speed throughout the calibration. Dynamic zero function duration will depend upon the number of revolution
chosen, and belt length and speed. The procedure can be left to complete its cycles or send exit calibration command
to interrupt.
• Sensor input control
A rising (positive logic) or a falling edge (negative logic) triggers a test routine of the sensor input and produces a test
result.
• Belt fault
Belt Fault function should be assigned to logical input. At this input activation on rising or falling edge (according to
the configured logic), Belt fault alarm is activated.
13.1.2 Analog output (IO+ version)
An optional analog board in current and voltage might be used with eNod4 to provide IO+ version. This must be asked
when ordering eNod4 product.
Voltage output might be set either 0-5V or 0-10V, and the current output to 4-20mA, 0-24mA , 0-20mA or 4-20mA
with alarm at 3.6mA. Both output (current and voltage) might separately be enable. Settings are effective after eNod4
reset.
Analog output affectation function is common to both current and voltage output and might be assigned to
followings:
