SAFETY INSTRUCTIONS
Before installing and commissioning the EasyBus
components, carefully read the entire manual. Take note in
particular of the operating instructions containing hazard
symbols and warning signs. Their non-observance could result
in damage to the unit and slight to serious personal injuries.
Should you have any questions, after reading through the
entire manual, please contact SCHAKO.
An exclamation mark within a triangle
indicates information which must be observed
by the user. Non-observance may result in
damage to the module or loss of data.
A lightning flash within a triangle warns
against
electric shock or impairment of the electrical
safety of the device.
This symbol indicates important information in
these operating instructions which must be
observed.

For this, a 7-segment display and a programming key are
integrated in each module. They can be used to make
settings.

CABLE LENGTH
The standard cable length from the module to the consumer
(BSK, ERK, RM) is 1 m including prepared connection option.
The max. cable length from the module to the bus line is 1.5
m.
The total cable length from the switch cabinet to the last
terminal of the EasyF module with 128 modules must not
exceed a length of 1000 m.
Moreover, a distance of at least 5 cm between two flat cables
is recommended if cables are installed, for example in ducts,
tracks, etc.
MODULE MOUNTING
To ensure connection, a minimum distance of 40 mm from
the four side surfaces to walls, ventilation ducts or similar is
recommended.
For removing the module cover, a minimum distance of 100
mm from the top side of the cover is recommended.
In addition, it is recommended to fasten the module at a
distance of max. 100 mm from edges of the inspection
opening to provide a good accessibility to the module during
commissioning or service activities.
FLAT CABLE SYSTEM
H corresponds to the cable thickness
R corresponds to the smallest recommended bending radius
When using the connection socket (-MASD), it is
recommended to fasten it using cable ties or the like.
The recommended distance between points for fastening of
the flat cable is between at least 500 mm and a maximum of
1500 mm.
(source: Installation instructions by Woertz)
The cable manufacturer always recommends to use an
additional strain relief by means of cable ties (see figures).
This reduces the tractive forces at the connection socket.
According to EN 61535 A1, tractive forces of 100 ±2 N are
allowed for a cable diameter of more than 16 mm.
SWITCH CABINET MOUNTING
When mounting the EasyS-W01 or –W02 switch cabinet, the
minimum distance of 0.8 m from the ground is
recommended. A minimum distance of 0.2 m (on the right or
left) is also recommended. This distance from a side surface is
also recommended for the EasyS-A01 to –A05 switch
cabinets.
For fastening the EasyS-W01 to W02 switch cabinets, select
the corresponding fastening material depending on the
masonry.

General information about addressing:
To set up an EasyBus network, at least one EasyS-MV2 and
one EasyS-FV1, at least one (up to max. 128) EasyF module
and a Modbus interface are required. The prerequisite for the
communication between an EasyS-MV2 and the users (at
least one (up to max. 128) of the EasyF modules is a complete
scan of the EasyBus network. The EasyF modules require a
unique address for it. This address can be assigned to each
module manually or automatically by the Easy-MV2. The
following sections describe options for assigning addresses.

- „b“ (baud rate)
- "P" (parity)

and hold down the programming key for a long period (>3s)
to display and adjust the corresponding settings. To confirm
the entry, hold down the programming key (>3s) until the
corresponding parameter has been completely set (max. 3
digits). Afterwards, the following submenu items "b", "P" and
"t" and their specific settings must be confirmed by holding
down the programming key (>3s). After that, the 7-segment
display goes out, the master restarts and switches to the
status display.

If no further changes to other submenu items must be carried
out, the programming can be finished at this point. After a
few seconds, the master will switch to the status display, the
change has been applied.
If changes must be also made to the submenus "b" (baud
rate), "P" (parity) and "t" (time out), they can be carried out
analogous to the Modbus address change.
