The following functionalities will be managed:
-Management of firing of an individual valve actuator;
-Management of firing of several valve actuators simultaneously;
The gateway unit will be able to manage:
-the signalling of valve actuation anomalies;
-setting communication parameters;
-the programming of registers for customised use;

Warning Symbols Used in the Manual
The indications regarding safety are highlighted using the following symbols:
Attention - Danger Warning - Generic
Risk –Hazard Electric Current
Dispose of according to the WEEE Waste Electrical
and Electronic Equipment Directive
Installation Regulations and Warnings
ÜProtect the equipment from direct sunlight.
ÜDo not position the device near heat sources and electromagnetic fields.
ÜMount the equipment to the wall at least 60 cm from the floor.
ÜIn a clearly visible place, which is easy to reach.
ÜConnect the equipment to supply lines different to those used for motor drives or other large power devices
that could generate network disturbances or instability.
ÜThe appliance electric power supply must be supplied by an external, type-approved power supplier unit, with
24Vdc 30W output, protected by a 230Vac~ 30mA differential circuit breaker and a 230Vac~ 10A bi-polar
magnet circuit breaker, positioned in a place that is easy to reach.
ÜBefore intervening on the appliance to perform any operation, deactivate the magnet circuit breaker.
ÜFor electrical operations, always remove the voltage and wait 30 seconds for the internal capacitors
to discharge before opening the container. When finished, close the device before turning on power.
ÜMake sure you are in a safe atmosphere before using the equipment for any type of operation.
ÜUse flame-proof cables with minimum section of 0.75mm² certified and compliant with IEC60227 or IEC60245
to connect the power supply voltage.
ÜUse flame retardant cables with a minimum section of 0.75 mm² for all input control signals.
ÜThe terminal board must not be a mechanical anchorage point of the wires.
ÜAny use not foreseen in this user manual and improper use of the device may cause damage to the same and
possibly to the connected equipment.
ÜMoreover, misuse or tampering with equipment could cause damage to people.
ÜThe gateway unit does not release potentially toxic or hazardous substances for health and the environment.
ÜNo part with dangerous voltage is normally accessible.
Do not use the control unit before reading and understanding this manual.

The electric connections between the circuit board of the gateway unit and the
system are made using removable connectors, in order to facilitate wiring.
The removable connectors allow the operator to fix the connection cables using
screws.
The connectors have the following features:
Body material : PA66 UL94V0
Pitch : 5.08mm
Nominal voltage : 450V
Nominal current : 20A
temperature : -40°C +105°C
Configurations and displays
The gateway unit circuit board has a series of components that allow configuration of
the ModBus address of the unit and display of the status of activities. The positions of
the main components are indicated in the image:

Gateway Unit address setting
Before connecting the Gateway unit to the RS-485 RTU ModBus network, a unique
device address must be set, so that the other peripherals of the same network can
recognise it and manage it, thus preventing network conflicts.
DIP 1
Using the 4
-
position dip
-
Switch DIP1, addresses can be set in the 1
-
15 range (0=invalid
address), moving the 4 DIP switches into the desired position, according to binary
logic.
Example:
Set value 13…
(Bin = 8+4+1)
Code
Binary 8 4 2 1

Gateway Unit Reset
The gateway unit has a general reset button, indicated with K1 and located on the
right hand corner of the circuit board, which allows the unit to be rebooted if
necessary.
By pressing and holding for at least 3 seconds, all temporary registers of the gateway
unit are Reset and the same resumes operations after approx. 10 seconds.

ModBus Communication Port Configuration
The gateway unit uses a standard, isolated type, RS485 communication port (Physical
layer), for connection to a RTU ModBus network, on which other devices are present
e.g. PLC, Personal Computer, Monitors, HMI, I/O modules.
On commissioning, the communication port of the gateway unit is configured as
follows:
Parameter
Value
Using the 4
-
position dip
-
Switch DIP1, present on the
circuit board, an RS485 network address can be assigned
to the unit. This address must be unique in order to
prevent conflicts with other units present on the same
communication network.
