5.1.3

Setting the direction of rotation

Once the pump has started up, the user must ensure that the direction of rotation is correct (the direction
is usually indicated by an arrow on the pump casing). To start up the motor and check the direction of
rotation, simply switch on a utility.
From the same menu as RC (MODE SET – "Installer menu") press MODE and scroll through the menus
to RT. In these conditions, buttons + and – enable the user to invert the direction of motor rotation. The
function is also enabled when the motor is running.
If it is not possible to see the direction of motor rotation, proceed as follows:
Method to check rotation frequency
- Access parameter RT as described above.
- Turn on a utility and observe the frequency that is shown on the status bar at the bottom of the utility control
page, to ensure that the operating frequency is less than the rated frequency of the pump FN.
- Without changing collection, modify parameter RT by means of buttons + or – and check frequency FR again.
- The correct RT parameter is that which requires, compared to collection, a lower frequency FR.
5.1.4

Setting the flow sensor and pipeline diameter

From the installer menu (the same used to set RC, RT and FN) scroll through the parameters using
MODE to reach FI.
To work without a flow sensor, set FI at 0; to work with the flow sensor set FI at 1. Use MODE to scroll
through to the next parameter FD (pipeline diameter) and set the diameter in inches of the pipeline on
which the flow sensor is mounted.

5.1.5

Setting the setpoint pressure

From the main menu, press and hold MODE and SET simultaneously until "SP" appears on display. In
these conditions, buttons "+" and "–" enable respectively increase and decrease of the required pressure
value.
The regulation range depends on the sensor used.
Press SET to return to the main page.
5.1.6

Setting other parameters

After the initial start-up procedure, the other pre-set parameters can be modified as required, by
accessing the relative menus and following the instructions for the specific parameters (see chapter 6).
The most common parameters are: restart pressure, regulation gain values GI and GP, minimum
frequency FL, water failure time TB, etc.
