6.5.2 RT: Setting the direction of rotation

This parameter is present only on type M/T and T/T inverters.
If the direction of pump rotation is incorrect, it can be inverted by changing this parameter. In this menu item, use
buttons + and – to activate and display the two possible states "0" or "1". The phase sequence is shown in the
comment line on display. 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:
Turn on a utility and check the frequency.
o
Without changing collection, modify parameter RT and check the FR frequency again.
o
The correct RT parameter is that which requires, compared to collection, a lower frequency FR.
o
CAUTION: on some electric pumps, it may occur that there is little difference in frequency in the two cases, and it is
therefore difficult to understand which is the correct direction of rotation. In these cases, repeat the test described
above, but rather than checking frequency, attempt to check the phase current absorption (parameter C1 in the user
menu). The correct RT parameter is that which requires, compared to collection, a lower phase current C1.

6.5.3 FN: Rated frequency settings

This parameter defines the rated frequency of the electric pump, and can be set from a minimum of 50 [Hz] and
maximum of 200 [Hz]. In the case of a type M/M inverter, the FN setting may be 50 or 60 Hz.
Press "+" or "-" to selected the required frequency starting from 50 [Hz].
The values 50 and 60 [Hz] have priority over other selections as they are the most common: on entry of any frequency
value, when the value 50 or 60 [Hz] is reached, the increment or decrement stops; to modify the frequency from one of
these two values, release each button and then press "+" or "-" for at least 3 seconds.
When the value is modified, the parameter symbol starts to blink, indicating that the value has changed. The
modification will be effective only when [SET] or [MODE] is pressed or when the menu is changed. If you do not press
any key after having changed the parameter and leave the page by timeout, the change will not be effective.
Each modification to FN is interpreted as a system change, and therefore the parameters FS, FL and FP are adjusted
automatically according to the set FN. On each variation to FN re-check FS, FL, FP to ensure settings are as required.

6.5.4 UN: Setting the rated voltage

This parameter is present only on type M/M inverters, size 11 and 14 [A].
It defines the rated voltage of the electropump and may be set on two possible values:
110/127 V
220/240 V

6.5.5 OD: Type of system

Set with two possible values (1 and 2) according to a rigid or flexible system.
The inverter leaves the factory set to mode 1, suited to most systems. In the event of pressure variations that cannot
be stabilised by adjusting parameters GI and GP, switch to mode 2.
IMPORTANT: In the two configurations, the values of adjustment parameters GP and GI also change. Furthermore,
the values of GP and GI set in mode 1 are stored in a different memory from the GP and GI values
set in mode 2. Therefore, for example, the value of GP in mode 1, when switching to mode 2, is
replaced by the GP value of mode 2, but is stored and restored on return to mode 1. The same value
seen on display has a different meaning in each of the modes, as the check algorithm is different.

6.5.6 RP: Setting the pressure drop for restart

This shows the drop in pressure, with respect to the value SP which causes pump restart.
For example, if the setpoint pressure is 3.0 [bar] and RP is 0.5 [bar] the pump is restarted at 2.5 [bar].
RP is normally set from a minimum of 0.1 to maximum 5 [bar]. In special conditions (for example in the case of a
setpoint lower than RP) this can be limited automatically.
To facilitate the work of the user, the RP setting page, highlighted below the symbol RP, shows the effective restart
pressure; see Figure 14.
