6. MODBUS

You have bought the automatic selector valve that includes the features of the MO-
DBUS RTU.
MODBUS is an open communication bus that is widely used to connect different de-
vices to a main control. This is the reason why this standard of communication has
been chosen, it is easy to integrate with other products of the same brand and even
with a wide range of products from other suppliers.
MODBUS, MODBUS-RTU and other related names are registered brands of MODBUS
Organization. It is possible to obtain additional information and documentation at
http://www.modbus.org/.
MODBUS allows the control and supervision of some of the valve operations, as well
as helping in preventative maintenance and the analysis of defects, thanks to the im-
plementation of internal registers on the possible actions and most relevant errors.
The valve is ready to work with MODBUS, but it can work in a local mode like a tradi-
tional valve without the need to connect the communication system.
The control system allows it, for example, to be moved to a specifi c position, inform
on errors and on the operating history and other features that offer the user/installer a
wide range of new possibilities based on automation.
To obtain more information, consult the specifi c manual of MODBUS, that is provided
by the valve's manufacturer.

7. SOLUTION OF POSSIBLE PROBLEMS.

We attach a list of possible problems that can occur with the valve, together with the
best solution.
If the MODBUS communication bus is used, please consult the specifi c manual to
solve the possible incidents.
Specifi c case: The situation might arise that owing to the a problem in installation
(air working in depression) the time needed to prime the pump is greater than that
programmed for the wash and rinse cycles, something that would cause the valve to
start this operational mode without the fi lter working correctly.
