1. There are a maximum of 8 points for each programmable curve.
2. With ohm values for the resistance value of the sensor curve. The resistance
values of the sensor response curve must be entered in descending order, that
is, the rst point should correspond to the highest resistance value, the second
point to the second highest resistance value, and so on. Only positive resistance
values are permitted when programming the sensors curve points.
3. The temperature values of the sensors curve points must be entered in
degrees Celsius. Positive and negative temperature values are permitted when
programming the sensors curve points.
4. The pressure values of the sensors curve points must be entered in
kilopascals. Only positive pressure values are permitted when programming the
sensors curve points.
5. The temperature curve can be applied to both the coolant temperature sensor
and the auxiliary sensor (by default, oil temperature).
6. The pressure curve is applied to the oil pressure sensor.
7.7 PROGRAMMING THE GAUGE RESPONSE CURVE
The CEA7 control unit allows the use of nonlinear response gauges for measuring
fuel. To this end, in addition to the response curves of the temperature and
pressure sensors, an additional curve can be programmed for the fuel level
sensors with up to 8 congurable points for each user. The rst programmable
curve corresponds to the fuel level input (NC) for a nonlinear response. The
second programmable curve permits a gauge for an auxiliary tank at the input
(AnC).
To program these curves from the option MenuParametersSensors, it is
necessary to:
1. There are a maximum of 8 points for each programmable curve.
2. With ohm values for the resistance value of the sensor curve. The resistance
values of the sensor response curve must be entered in descending order, that
is, the rst point should correspond to the highest resistance value, the second
point to the second highest resistance value, and so on.
NOTE
The existence of modules with the same ID is not permitted. If during start up a
display module detects another analogue module with the same ID, the
message will be displayed ERROR ID. DISPLAY.
NOTE
By changing the ID of a module, it automatically restarts. It is important to NOT
change the ID of measurements modules with the genset in operation.
7.4.2 ALLOCATION OF IDS
Because all the electronic modules have the ID 0 by default, for the
implementation of installations with multiple control units interconnected, it is
necessary to assign IDs to the various modules. For this purpose, it is necessary
to progressively switch on the various control units, assigning each of them
different IDs as they are connected.
7.5 RESETTING THE CURRENT MEASUREMENTS
In the event of an incorrect current reading when the genset is uncharged, it is
possible to perform a zero calibration (Table Measures, parameters 6, 8 and 10:
any of the 3 perform the resetting of the 3 current channels) of the Measurements
table.
7.6 PROGRAMMING ANALOGUE SENSORS CURVE
The CEA7 control unit has a series of temperature and pressure sensors curves
programmed for different VDO capsule types (model 323-803-001-008 for
temperature and model 360-081-030-009 for pressure) and engines (VOLVO,
JCB, SCANIA, YANMAR). Via parameter 29 on the Regulations table the type of
sensor installed on the generator set is selected.
In addition to the programmed curves, there are two sensors curves (one for
temperature and the other for pressure) with up to 8 points, each congurable by
the user.
To program these curves from the option MenuParametersSensors, it is
necessary to:
