I - ELECTRICAL CONNECTIONS
A- Wiring instructions
Factory fieldbus (EtherNet/IP™) is connected to one of the 2 ports of the embedded Ethernet
switch (shielded M8/RJ45 cable).
Connect the “COVAL bus” using the provided bridge connectors or M8/M8 female cable for re-
mote modules.
24V DC power supply is connected to the rear connector of the last secondary module of the
island (or to the rear connector of master module if used as standalone LEMCOM) through the
COVAL bus termination cable.
Standalone secondary module or “Secondary only” island?
Refer to chapter VI for wiring and initial setup.
The LEMCOM vacuum pump must be used with power supply units that provide
a Protective Extra Low Voltage (PELV) and with an isolation of the supply voltage
according to EN60204.
This guide provides first-time users with information on wiring the different modules of a
LEMCOM island and on setting up the LEMCOM.

B- Consumption
The LEMCOM structure implies that all vacuum generators connected together on the COVAL
bus are electrically supplied by the same power source. The consumption table(left) must be fol-
lowed when calculating the required power supply voltage and amperage.

II - CONFIGURATIONS AND ACCESSORIES
LEMCOM is based on an innovative product architecture:
The master module manages the fieldbus communication, handles secondary module man-
agement and is a complete vacuum pump. Its two communication ports ensure the continuity
of the fieldbus.
The secondary modules are interconnected with the master module via the COVAL bus.
The link between the master module and the secondary modules is handled by an M8 bridge
connector for island configurations or by a standard M8/M8 cable for configurations using re-
mote modules.
➊Cat 5 shielded Ethernet cable: M8, straight, female, 4-pin – RJ45, straight, male, 8-pin –
suitable for drag chain use
CDM8RJ45L2: length 2 m.
CDM8RJ45L5: length 5 m.
CDM8RJ45L10: length 10 m.
➋Cat 5 shielded Ethernet cable: M8, straight, female, 4-pin, on both ends – suitable for
drag chain use
80003053: length 1 m.
➌“COVAL bus” bridge connector
80001231
➍120 Ω“COVAL bus” termination: M8, straight, female, 4-pin – M8, plug, male, 4-pin
80002303: length 0.2 m.
The COVAL bus is based on a CAN architecture and requires
the addition of a bus termination to ensure proper communi-
cation between the secondary and master modules.
It takes the form of an M8 male/M8 female cable that includes a 120 Ωline termination
resistor.
It must be integrated on the last secondary of the COVAL bus, between the module’s rear con-
nector and the 24 V DC power supply.
When using a stand-alone master module, this termination is not required.
➎Power supply cable: M8, straight, female, 4-pin – open end
CDM8: length 2 m.

cations. Depending on the chosen model (LEMC60X or LEMC90X), the LEMCOM module is
configured as shown opposite.
Recommendations
Default vacuum parameters may need to be adjusted to perfectly suit the requirements of your
application. If this is the case, we recommend observing the following conditions:
L2-h2 > L1 regulation zone should be above the “object gripped” threshold
h1<L1 hysteresis should be lower than “object gripped” threshold
h2<L2 hysteresis should be lower than “regulation” threshold
In case of rough or porous product handling, disable ASC to avoid vacuum pilot from turning
ON and OFF frequently.

Standalone secondary module or modules of a “secondary only” island are factory set to address
#16 to avoid any address conflict.
User must assign a valid and unique address (#1 to #15) to each secondary module to
make them “visible” on the COVAL bus. LEMCOM Manager software or web server can be used
to complete this operation.
1- Wire the modules.
Connect secondary module(s) to the master LEMCOM module using M8/M8 female cables.
2- Connect to the master module using LEMCOM Manager software.
Default password: coval
3- Assign an address.
Click on the button of the first blank slot, then click OK.
4- Follow the instructions.
5- Repeat these steps with a different address for each secondary module that is to be add-
ed to the COVAL bus.
NOTES
-Press and hold SET button (on a secondary module) during power-up to reinitialize its
address to #16 (release the button when MS LED starts flashing).
-Access to “Configuration Mode” in LEMCOM Manager is password-protected. Default
password is : coval

VII- EtherNet/IP™ communication
Please refer to the main user manual (ref. LMEIP-UK-x-1155UM0067) for detailed set-
up instructions, data mapping and general recommendations.
1- LEMCOM general properties
With respect to the EtherNet/IP network, the LEMCOM master module is an EtherNet/IP
adapter.
It receives implicit communication connection requests from an I/O scanner (the Programmable
Logic Controller) then produces or consumes its I/O data based on a Requested Packet Inter-
val (RPI) value.
2- I/O assembly instances
Input and output data refer to the master module and to the secondary modules that may be as-
sociated with it.
As an example:
“Vacuum Control” output data consists of 2 bytes and each bit toggles the vacuum of LEMCOM
module #0 (master) to #15 (last secondary).
“Vacuum level” input data consists of 16 bytes and each byte represents the instant vacuum
level (%) of LEMCOM module #0 to #15.
For best performance and sufficient diagnostic data, we recommended using I/O assembly
instances 140 and 110.
2-1 Input instances (Target > Originator)
Data sent from the LEMCOM island to the controller every ‘RPI’ ms.
Note: Input instance 141 is designed to be used with output instance 111.
2-2 Output instances (Originator > Target)
Data sent from the controller to the LEMCOM island every ‘RPI’ ms.
In this assembly, the first bit of byte 5 allows or rejects the modification of the LEMCOM module’s
settings. When it is enabled, the parameters data set defined in bytes 6 to 73 are automatically
sent to the LEMCOM master module every ‘RPI’ ms.
We highly recommend setting the “settings modification allowed” bit to ‘0’ in the PLC’s pro-
gram and only toggling it to ‘1’ when new settings must be applied.
3- Configuration instance
The configuration assembly instance 160 is used to transfer the vacuum settings to all LEMCOM
modules of an island (1 to 16 modules). The parameters are sent by the PLC to the master LEM-
COM module when the EtherNet/IP communication is established.
Please note that, unlike LEMCOM Manager, which warns the user in case of incorrect parame-
ters, the configuration assembly lets the user send any settings.This may lead to the appearance
of warnings on the module’s front panels (for example: threshold or hysteresis set to 0).
The output instance 112 is designed for specific applications that need to edit the
LEMCOM module’s parameters directly from the PLC or an EtherNet/IP HMI. It must
be used with special care.
If the configuration instance is used, please note that any modifications made to the
settings using LEMCOM Manager will be overwritten by the data of instance 160 the
next time communication is reset.
