3.2.4 UCOUNT

As per the UValve, there are two terminals (IN and OUT) for the CANBUS.
For connecting the UCount with external flow control unit (24VDC solenoid valve and pulser), you need to use the A B COM SV OUT1 terminals.
Connect the COM terminal of the pulse meter to the COM terminal (5) of the UCount electronic board. Connect the pulse generator terminal of the
pulser to terminal "A" (9) of the UCount. If the pulser has a double reed switch connect the other pulse generator terminal of the pulser to terminal
"B" (7) of UCount electronic board.
The device has 3 screen display modes, named "standby mode,
"standard" mode and "XXL" mode.
The "standby" mode (figure 1) is the display mode shown when no
transaction is in progress. While a transaction is being made, the screen
will show the "standard" mode (figure 2) or the "XXL" (figure 3)
according to the device configuration (see the "menu configuration"
section for more details).
Depending on the screen mode, the unit address (1), the fluid volume
dispensed (2), the progress status bar of the transaction (3) or the
indicator which shows that the solenoid valve is open (4),
will be displayed.
