INSTALLATION<br />
PRESSURE TRANSDUCER<br />
The point of operation required by the full power supply (FVS) can be adjusted by acting on the screw (R) of the pressure<br />
transducers.<br />
The factory settings of the transducers P35AC are:<br />
8 - 14 bar = 10 bar (=FVS)<br />
14 - 24 bar = 16 bar (=FVS)<br />
Minimum Speed<br />
In or<strong>de</strong>r to avoid that the fan speed goes below accepted levels, the power of the minimum speed (Vrms) can be set between<br />
45% and 90% of the power supply by acting on the knob of the electronic module P38AA.<br />
The value of the minimum speed is reflected on the proportional band . The higher the value of the minimum speed, the<br />
lower the actual proportional band.<br />
Cut-off Point<br />
If the controller does not need to run at minimum speed, set the knob that is on the electronic module at the cut-off point. The<br />
output to the motor will be cut-off the moment the pressure <strong>de</strong>scends below the value of the operating point required less the<br />
proportional band (the fan stops).<br />
The control is factory set so that the fan is able to work from 0 to 100% of its speed, since the fans normally used are capable<br />
of operating throughout the whole tension range.<br />
System control<br />
Once the control unit has been installed and adjusted, check the system by making the equipment run for at least one full<br />
operating cycle. If something should not operate correctly, check both the wiring as well as the components.<br />
