ENGLISH
To install the handle, position the handle* (14) (APPENDIX 1 - Fig. 6) such that the triangle on the bell
shaft always coincides with the handle positioner (9). Once it is installed, the pin* (10) can be inserted .
In the event that there is an electrovalve in the drainage system, turn the lever (APPENDIX 1 - Fig. 9 - detail
1) to position manual.
The 3 position switch, On "II", Hi "I" should be in the "I" position.
* Supplied as spare parts.

5.4 HOW TO CHANGE THE VALVE FROM MANUAL TO AUTOMATIC OPERATION.

Remove the pin (10) (APPENDIX 1 - Fig. 6), remove the handle (14) and install the part (7) (APPENDIX 1 -
Fig. 5). This is accomplished by orienting the mark (A) such that it coincides with the triangle (APPENDIX
1 - Fig. 6). Once fitted in place, the pin (6) (APPENDIX 1 - Fig. 5) should be inserted, which should be centred
along its length. Then install the part (5) (APPENDIX 1 - Fig. 4). Slot the inside notch (15) into the
mark (16). See assembly illustration in APPENDIX 1, fig.7. Which should be well-positioned (it only has
one mounting direction). Insert the screw (3) and screw in. It should not be fully tightened since it has to
be loosened in order to orient it with the pin (4) on the motor assembly. At this point, it is now possible
to install the module assembly as described in the valve module installation process.
In the event that there is an electrovalve in the drainage system, turn the lever (APPENDIX 1 - Fig. 9 - detail
1) to position nº2 (automatic).
Control box: The 3 position switch, On "II", Hi "I" should be in the "II" position.

6. MODBUS.

You have bought the automatic selector valve that includes the features of the MODBUS RTU.
MODBUS is an open communication bus that is widely used to connect different devices 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 implementation 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 traditional valve without
the need to connect the communication system.
The control system allows it, for example, to be moved to a specific 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 specific manual of MODBUS, that is provided by the 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 specific manual to solve the possible incidents.
