SCAIME Manual : NU-eNod4C-E-0418-196712-F.docx
eNod4* is an analog data processing unit evaluated as a part of a non-automatic weighing instrument (NAWI) with
applicative software -T or an automatic weighing instrument (AWI) like an automatic gravimetric filling instrument with
applicative software -D or a catchweigher with applicative software -C. This instrument is not intended for direct sales
to the public. It is suitable for conditioning OIML R60 certified strain gauges load cell(s) with analog output.
Legal for trade mode has to be activated internally in order to respect metrological requirements. All the functionalities
will be conformed to the essential requirements for certified weighing instruments.
Sealing will be material on the eNod4 housing and load cell connections. If a junction box is used it will have to be sealed
too. eNod4 is fitted with a software sealing for metrological parameters and once activated, is composed of an event
counter and a CRC value of specific and adjustment parameters. These values shall be marked on the terminal device
connected after the last official verification when putting in service the instrument. Any mismatch between the
displayed values on the terminal and those marked will signify a broken sealing.
eNod4 is fitted with a data storage device (DSD) so called alibi memory. Any weighing result (or checkweigher result
with applicative software -C, or dosing result with applicative software -D) is stored internally and can be recalled on
demand. 130816 records can be stored permanently at maximum. Any record is identified by a unique 32-bit long
number. This identifier is incremented each time a weighing result is stored and transmitted.
The minimum time between two DSD recording operations is 50ms.
* legal for trade use does not apply to software applicative for beltweigher (-B) and weigh feeder (-F)

4.1 Cabling basic rules
4.1.1 Prevent Electrostatic Discharges
For ESD protection, cabling for the analog load cell must include a ferrite and a silicone protection sleeve, not included
with the transmitter.
Install the ferrite by passing the analog cell connection through the ferrite and wrapping it around once, as shown on
the following picture:
4.1.2 Prevent Electromagnetic disturbances
Observe these basic rules to guard against Electromagnetic disturbances.
Rule 1: Large area grounding contact
•When installing the devices, make sure that the surfaces of inactive metal parts are properly bonded to chassis
ground (see following sections).
•Bond all inactive metal parts to chassis ground, ensuring large area and low-impedance contact (large cross-
sections).
•When using screw connections on varnished or anodized metal parts, support contact with special contact
washers or remove the protective insulating finish on the points of contact.
•Wherever possible, avoid the use of aluminium parts for ground bonding. Aluminium oxidizes very easily and
is therefore less suitable for ground bonding.
•Provide a central connection between chassis ground and the ground/protective conductor system.
Rule 2: Proper cable routing
•Organize your wiring system into cable groups (high-voltage/power supply/signal/measurement/data cables).
•Always route high-voltage and data cables in separate ducts or in separate bundles.
•Install the measurement cables as close as possible to grounded surfaces (e.g. supporting beans, metal rails,
steel cabinet walls).

17
SCAIME Manual : NU-eNod4C-E-0418-196712-F.docx
Rule 3: Fixing the cable shielding
•Ensure proper fixation of the cable shielding.
•Always use shielded data cables. Always connect both ends of the data cable shielding to ground on a large
area.
•Keep unshielded cable ends as short as possible.
•Always use metal/metalized connector housings only for shielded data cables.
•Shields of load cells must be connected to the pin ‘Shield’ of the load cell connector of the eNod4 or, in case of
junction box, directly on the body of this one.
Rule 4: Special EMC measures
•For cabinet or enclosure lighting in the immediate range of your controller, use incandescent lamps or
interference suppressed fluorescent lamps.
Rule 5: Homogeneous reference potential
•Create a homogeneous reference potential and ground all electrical equipment.
Use sufficiently dimensioned equipotential bonding conductors if potential differences exist or are expected between
your system components.
Equipotential bonding is absolutely mandatory for applications in hazardous areas.
4.2 Power supply connection
On the front panel a green light ‘PWR’, (D7) indicates if power is connected.
4.3 Load-cell wiring
•4 wires load-cell: jumpers in place (by default at delivery).
•6 wires load-cell: jumpers removed

4.4 IO+ version
An analog board in current and voltage might be used with eNod4 to provide IO+ version. This has to be requested when
ordering eNod4 product. The analog output is both current and voltage galvanically isolated at 1000V.
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 alarm
3.6mA. It is software setting and both output (current and voltage) might separately be enable.
The IO+ version is fitted with two additional inputs IN3 and IN4:
The IO+ version is fitted with a pulse input and a dedicated power supply for a speed sensor (belt weigh feeder, belt
weigher). Two input voltage levels are proposed for the pulse input of the speed sensor: TTL logical level or high voltage
30 V maxi level.
