TechnipFMC Measurement Solutions, Inc. hereby disclaims any and all responsibility for damages, including but
not limited to consequential damages, arising out of or related to the inputting of incorrect or improper program or
default values entered in connection with the microLoad.net.
Receipt of Equipment
When the equipment is received the outside packing case should be checked immediately for any shipping damage.
remove the unit from its packing case and inspect for damaged or missing parts.
If damage has occurred during shipment or parts are missing, a written report should be submitted to
the Customer Service Department, TechnipFMC Measurement Solutions, Inc., 1602 Wagner Avenue, Erie, Penn-
sylvania 16510.
Prior to installation, the unit should be stored in its original packing case and protected from adverse weather
conditions and abuse.
Caution
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with this Instruction Manual, may cause interference to radio communications. It has not
been tested to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15
of FCC Rules, which are designed to provide reasonable protection against such interference when
operated in a commercial environment. Operation of this equipment in a residential area is likely to cause
interference, in which case the user, at his own expense, will be required to take whatever measures may
be required to correct the interference.
Warning
These preset devices must be used with fail-safe backup equipment to prevent accidental runaway delivery
of product. Failure to provide backup equipment could result in personal injury, property loss and equipment
damage.
Warning
On initial power-up of a new unit or after installation of a new computer board, there are several alarms that will be
triggered, which cannot be cleared until the microLoad.net is programmed.

Section II – Pre-Installation Considerations
An important pre-installation consideration is the se-
lection of the ancillary equipment to be used with the
microLoad.net and how that equipment is interfaced.
(Table 6, page 16) which will assist in the assignment
of devices to the microLoad.net’s various I/O positions.
The Worksheet lists the available I/O points versus
possible devices or functions which may be applied.
By checking the appropriate boxes on the Worksheet
I/O map of your application is established. A sample
application starts on page 40.
Mechanical
In addition to the following, all previous warnings and
cautions should be reviewed before installation.
1. A solid vertical or slanted surface should be used
for mounting the explosion-proof microLoad.net
housing.
2. The location and the height of microLoad.net should
be selected to permit easy viewing of the display
and to provide convenient access to the keypad
by all users. See Figure 2 for dimensions of the
microLoad.net.
cover. For service, wiring and removal of parts the cover
must removed.
4. Conduit entry to the explosion-proof microLoad.net
is both through the bottom and sides. There are two
the unit.
5. Inwarm climates,microLoad.net shouldbe shadedfrom
direct sunlight. The maximum external temperature
of the microLoad.net housing must not exceed 140°F
(60°C) to ensure that the internal temperature limit is not
exceeded.
Electrical
Note: See Appendix A for information regarding ATEX electrical
installation.
1. All DC wiring must be routed into microLoad.net
through the conduit entries located in the bottom of
the housing. Do not route DC and AC wiring through
the same conduit entry.
2. The DC signal wires must be multi-conductor
shielded cable of 18 to 24 AWG minimum stranded
copper.

ration is used where the microLoad.net units are
networked through a hub or switch.
Note: The following recommendations are based on our knowledge
of the electrical codes. The local electrical codes should be reviewed
to ensure that these recommendations follow the local code. Also
installation manuals of all the equipment being wired into the micro-
Load.net should be reviewed for transmission distances and wire
recommendations.

4. All AC wiring must be routed into microLoad.net
through the conduit entries located in the side of
the housing. Connectors sized for a maximum of 14
gauge wire, consult the local electrical codes for the
minimum AC wire size required for your application.
Do not route AC and DC wiring through the same
conduit entry.
5. All AC wiring should be stranded copper and must
comply with federal, state and local codes and
6. Two separate AC circuits must be provided from
the breaker panel. One circuit will supply isolated
power to the microLoad.net electronics (instrument
power). The second circuit will supply power to the
external devices.
7. For proper operation, the microLoad.net must be
earth grounded. The grounding point should be as
close to the unit as possible. To ensure proper earth
a) The resistance between the earth ground lug in
the microLoad.net and the grounding point must
not exceed 2 Ω.
copper stake that extends into the water table.
Where this is not practical, a ground plane may
be used.
Note: Electrical conduit, piping, and structural steel are
not considered proper grounding points for equipment using
electronics.
c) No other devices, except the microLoad.net
and ancillary equipment such as load printers,
should be connected to any point in the ground-
ing circuit.
Section II – Pre-Installation Considerations
8. All user wiring is terminated at compression-type
screw terminal strips. These terminal strips may be
removed from the microLoad.net MACF and MNET
circuit boards to facilitate ease of wiring. Once wir-
ing is complete, the terminal strips are then “plugged
into” their respective positions on the circuit boards.
9. If external relay permissives are used in series with
microLoad.net AC digital outputs, an RC network
must be placed in parallel with the permissive to
prevent a false turn-on of the microLoad.net digital
capacitor and a 680 Ωresistor (Electrocube part
10. Interposing relays must be installed between the
pump controller, alarming device, and the micro-
Load.net permissive sense relays. Permissive
sense inputs are DC voltage.
Mechanical
1. Mount the microLoad.net using four (4) 5/16 - 18
bolts. See Figure 2 for mounting hole layout.
2. Attach the required conduit runs to the microLoad.

cover/keypad/display. This is done by removing six
(6) cap screws, which hold the cover to the micro-
Load.net enclosure. Carefully pull the cover away
from the enclosure and unplug factory-installed
cables by removing the terminal blocks at the MNET
circuit board. Note the position of these connections
for reinstallation later.
4. Care must be taken in handling the microLoad.net
enclosure and cover to avoid scratching the ground

4. All exposed shields must be properly insulated to
prevent short circuits to other terminals or to the
chassis. The shield at the device (e.g., tempera-
ture device, transmitter, etc.) must be cut back to
continuous. If splices are required, they must be
soldered and properly insulated.
If other communicating devices are used with the
microLoad.net, refer to the manual for that unit for
shielding information. Shields for other communi-
cating equipment should not be terminated in the
microLoad.net.
Note: Shields must not be terminated at the earth ground lugs.

boards can be replaced without removing individual
wires.
6. There is an earth ground lug provided in the unit.
The wire from the lug should be connected to the
proper grounding point. See Pre-Installation Con-
siderations, page 4.
Note: CENELEC approved microLoad.nets require that the
customer install ferrules (Aderendhulsen) per DIN 46 228 on
the grounding wires prior to installation into the grounding lugs.
7. Typical electrical installation diagrams are provided
in the following sections to show the microLoad.net
and ancillary equipment. Before wiring the ancillary
equipment, refer to its installation manual. Use the
installation diagrams in conjunction with the following
checklist to make all necessary connections to your
microLoad.net.
8. Reconnect all terminal blocks to their respective
positions on the MACF and MNET boards. These
terminals blocks are not “keyed”, therefore take
extreme care to be certain that terminal blocks are
returned to the correct position and are in the correct
orientation.
