malfunctioning.
Check if the rotation direction
of the actuator
*
is correctly set
(refer to the FIRST START UP
PROCEDURE section).
Set the rotation direction of the actuator
to Y2 (refer to the
FIRSAT START UP
PROCEDURE section).
Check if the valve actuator
*
is
set in manual mode (refer to the
Manual opening activation for
motorized valves
section).
Set the actuator in the automatic mode
(refer to the
Manual opening activation
for motorized valves section).
Check the correct installation
and electrical connections of the
Discharge Valve (V1). Referring to attached flow and
connections diagrams, ensure the valve is
correctly installed and connected.
Check if manually operating the
three-way valve (refer to the
Manual opening activation for
motorized valves
section), the
valve rotation is blocked.

13.1.1 Manual opening activation for motorized valves
When the Discharge Valve (V1), the Sludge Discharge Valve (V2) or both the valves ore blocked or do not automatically open
for any other cause, it will be necessary to perform a Valve Manual Opening procedure on the valve that faults.
To perform a Valve Manual Opening procedure follow the steps, listed below:
1. Press the appropriate black button on the top of the actuator and block it in this position (refer to figure below);
2. Then work manually on the lever of the valve and turn it manually, using the lever extension supplied with the plant;
3. Finally reset the actuator in automatic mode by pressing and release the black button (refer to figure below).
