Fp: Test Frequency Setting; Vp: Display Of Pressure; C1: Display Of Phase Current; Po: Display Of The Power Delivered - DAB ACTIVE DRIVER PLUS M/T 1.0 Installations- Und Wartungsanleitungen

When the buttons SET and - are pressed simultaneously for 2 seconds, the pump changes direction of rotation. The
function is also enabled when the motor is running.

6.4.1 FP: Test frequency setting

This displays the test frequency in [Hz] and enables modification by means of the buttons "+" and "-".
The default value is FN – 20% and can be set between 0 and FN.

6.4.2 VP: Display of pressure

System pressure measured in [bar] or [psi] depending on measurement system selected.

6.4.3 C1: Display of phase current

Phase current of electric pump in [A].
If the maximum allowed current is exceeded, the current value shown on the display will start to blink between normal
display and reverse. This representation indicates a pre-alarm condition which foresees the probable tripping of the
overload protection on the motor. In this case it is necessary to check the correct setting of the maximum current of
the RC pump, see paragraph 6.5.1 and the electric pump connections.

6.4.4 PO: Display of the power delivered

Power delivered to the electropump in [kW].

6.4.5 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 after entering manual mode, proceed as follows:
Start up the pump at frequency FP (pressing MODE and + or MODE + -)
o
Turn on a utility and check the pressure
o
Without changing collection, modify parameter RT and the pressure again.
o
The correct RT parameter is that which generates a higher pressure.
o
6.4.6 VF: Flow display
See paragraph 6.2.1

6.5 Installer menu

From the main menu, press and hold "MODE" & "SET" & "-" simultaneously until "RC" appears on display (or use the
buttons + or – in the selection menu). This menu enables the display and modification of various configuration
parameters. The MODE button enables the user to scroll through the menu pages, while buttons + and – enable
respectively to increase and decrease the value of the parameter concerned. To exit the current menu and return to
the main menu, press SET.

6.5.1 RC: Electric pump rated current setting

Rated current absorbed by the electropump in Ampere (A).
Insert the absorption declared by the manufacturer on the data plate of the electropump.
In the case of type M/T and T/T inverters, pay attention to the type of connection used for the windings.
If the parameter entered is lower than the correct value, the error "OC" is displayed during operation as soon
as the set current exceeds the current set value for a set time interval.
If the parameter entered is higher than the correct value, the current sensitivity protection will trip
inadvertently over the motor safety threshold.
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.
