Electrical connections
The
ES-FLOW™
is equipped with one or more electrical connection ports. The image to the
right shows the locations of the different ports (the actual presence and appearance of ports
might be different, depending on the ordered fieldbus interface and instrument type):
1. Standard connection port, 8-pin M12 male
2. Fieldbus connection port, 5-pin M12 male/female (optional, fieldbus dependent)
3. Connection port for actuator output, 4-pin M8 female
4. 2nd fieldbus connection port, 5-pin M12 male/female (optional, fieldbus dependent)
See sections
for configurable and installed options
respectively.
Upon delivery, all connection ports are capped. To maintain the original ingress protection rating, do not remove the caps
of unused connectors.
·
Electrical connections must be made with standard cables or according to the applicable
·
When using self-assembled cables, follow the guidelines provided by the connectors' manufacturer.
·
For use in a fieldbus system, follow the instructions of the cable supplier for the according fieldbus system.
·
Make sure that the power supply is suitable for the power ratings as indicated on the serial number label (see
or in the technical specifications, and that double or reinforced insulation is used for the power supply.
·
Before powering up, make sure all required cabling is properly connected.
·
Before each use, inspect cabling and connectors for damage.
Never
power the instrument simultaneously from
two different power sources
(e.g. fieldbus and Plug-in Power Supply).
Doing so will damage the printed circuit board irreparably.
The device described in this document contains electronic components that are susceptible to
electrostatic discharge
. In
order to prevent damage, proper handling procedures must be followed during installation, (dis)connecting and removing
the electronics.
The device carries the CE-mark and is
compliant with the concerning EMC requirements
. However, EMC requirements
can only be met using appropriate cables and connector/gland assemblies. Bronkhorst recommends the use of their
standard cables. These cables have the right connectors and loose ends (if any) are marked to help prevent wrong
connection. When using other cables, cable wire diameters must be sufficient to carry the supply current, and voltage loss
must be kept as low as possible. When in doubt, contact your Bronkhorst representative.
When connecting the product to other devices, be sure that the integrity of the shielding is not affected;
always use
shielded cabling for signals and communication and do not use unshielded wire terminals.

Communication interface
Check if the default network settings match the configuration of the fieldbus system (if applicable). If necessary, the default
settings can be overruled by changing the appropriate parameters (see
).
