With reference to the example in Figure 11 and using the factory settings of the inputs (I1 = 1; I2 = 3; I3 = 5; I4=10) the following is
obtained:
• When the switch is closed on I1 the pump blocks and error code "F1" is displayed
(e.g. I1 connected to a float; see para. 6.6.13.2 External float function settings).
•
When the switch is closed on I2 the control pressure becomes "P2"
(see para. 6.6.13.3 Auxiliary pressure input function settings ).
• When the switch is closed on I3 the pump blocks and error code "F3" is displayed
(see para. 6.6.13.4 Settings for system enable and fault reset) .
•
When the switch is closed on I4 after time T1 the pump blocks and error code F4 is displayed.(see para. 6.6.13.5 Setting
low pressure detection).
The example in Figure 11, refers to a connection with voltage-free contact, using the internal voltage to control the inputs (obviously
using only useful inputs). If a voltage rather than a contact is available, this can still be used to control the inputs: in this case
terminals +V and GND are not used and the voltage source (complying with the specifications of Table 7) is connected to the
required input. If an external voltage is used to control the inputs, all the circuitry must be protected by double insulation
.
CAUTION: the pairs of inputs I1/I2 and I3/I4 have a pole in common for each pair.
3. KEYBOARD AND DISPLAY
Figure 12: User interface layout
The machine interface comprises a yellow Oled display (64 X 128) with black background and 4 buttons named "MODE", "SET",
"+",and "-"; see Figure 12.
The display shows the inverter values and statuses, and indicates the functions of the various parameters.
The button functions are summarised in Table 9.
The MODE button enables the user to move to the next items in the same menu. When pressed for at least 1
sec it enables the user to skip to the previous menu item.
The SET button enables the user to exit the current menu.
This decreases the current parameter (if modifiable).
This increases the current parameter (if modifiable).
