Technical Handbook
•
The current managing mode of the fuel pump (MAN-OFF, MAN-ON, AUTO).
•
The pump status (on/off).
•
An indication of the fuel level referred to the pump management (starting required,
arrest required, in hysteresis).
If the pump management is linked to the analogue level sensor, then the controller board
displays, by means of a graphic bar, the current fuel level showing also the thresholds for
pump start/arrest.
From this page you can change the management mode for the fuel pump without having to go
to programming. To do that, you must:
•
Press the ENTER button: the square brackets between which the current mode is
displayed start flashing.
•
Use the vertical scrolling buttons UP and DOWN to select the desired mode.
•
Confirm with ENTER or cancel the modification with ESC.
For a detailed description of the features offered by the controller board for the control of the
fuel pump, see 9.7.13.
Pages S.11, S.12 (DIGITAL INPUTS) display respectively:
•
S.11:
o
The status of the digital inputs of the controller (JN, JT).
o
The status of the analogue inputs (JQ, JM and JL) when they are
used “as
digital
” (otherwise dashes are shown)
o
The status of the virtual digital inputs.
•
S.12:
o
The status of the digital inputs of the first DITEL module.
o
The status of the digital inputs of the second DITEL module (if present).
Page S.12 is hidden if no DITEL modules is present.
When you press the ACK/ENTER button, the controller changes the visualization through
three different modes (LOGICAL STATE, PHYSICAL STATE, BY FUNCTION), showing the
statuses of the digital inputs:
•
LOGICAL STATE
: the input's logic state (active or inactive) used by the controller in
the management of the operating sequence.
•
PHYSICAL STATE
: electrical level (active or inactive, or high or low) present on the
input; this can be the opposite in comparison to the corresponding logic state.
Displayed in negative.
•
BY FUNCTION
: it shows a list of the most common functions really configured for the
digital inputs, each of them with the logical status of the input that acquires it (it is not
possible to understand which input acquires a specific function, but only the fact that
this input is active or not). If more than six functions must be shown, the controller
shows all them by rotation (every 2 seconds, keep pressed the SHIFT button to stop
the rotation)
Pages S.13, S.14 (DIGITAL OUTPUTS) display respectively:
•
S.13:
o
The status of the digital outputs of the terminals JE.
o
The status of the digital outputs of the terminals JL (START, FUEL).
o
The status of the digital outputs of the terminals JI.
o
The status of the digital outputs of the terminals JT.
•
S.14:
o
The status of the digital outputs of the first DITEL module.
o
The status of the digital outputs of the second DITEL module (if present).
