This mode allows the display and change of the programming parameters.
WARNING! Assigning an incorrect value to one or more parameters can cause
malfunctions, damage to things or injury to people. The parameters must only be
changed by qualified personnel. Parameters may be password protected (see par.
6.5.1.1).
Each parameter (3) is associated with a 4-digit numeric code ("0116" in the example) which
allows to identify itregardless ofthe language used.Thecurrent value of the parameter("400")
is shown in brackets below the description ("Renewables nominal voltage (V)").
The first line below the title bar (2), allows you to identify the current menu by means of a
numeric identifier ("1.4") anda language-dependent description ("Renewable sources"). In this
row a pair of numbers (“3/06”) is displayed on the right. The first number indicates which menu
item is selected, the second indicates how many items are present in the menu.
Pressing ESC/SHIFT button, the first line (1) is temporarily substituted with a status
message.
Use the ▲ and ▼ buttons to select the programming mode (press them until "PROGRAM"
appears on the display). Then press the ACK/ENTER button to access the programming
menus.
After this operation, the controller will show the last parameter or the last menu used by the
operator. If it is not what you want, use:
•The ▲ and ▼ buttons to select a submenu or parameter.
•The ESC/SHIFT button to go back to the upper menu.
•The ACK/ENTER button to enter a submenu.
When the display shows the parameter to be modified, the current value of the parameter is
shown in square brackets, for example "[0400]". If instead it is enclosed in the symbols "<>"
(for example "<400>"), it means that you do not have the rights to modify the parameter. This
may depend on:
•The device is not in OFF/RESET mode. In fact, most of the parameters can only be
changed in this mode.

•The parameter is protected with a password: to modify the parameter, first enter the
required password in parameter "0000" (see later).
To modify a parameter, press the ACK/ENTER button: the square brackets flash. Use the ▲
and ▼ buttons to change the value and press ACK/ENTER to confirm or ESC/SHIFT to cancel
the change.
To exit the programming menu, press the ESC/SHIFT button several times until you return to
the main page (which displays the word PROGRAM in the centre).
You can directly accessthe last programming page displayed. This is possible if, when leaving
the programming, instead of going back up the menus to the exit, keep the ESC/SHIFT button
pressed for about 2 seconds (or change the operating mode from OFF/RESET to MAN or
AUTO) .
Some parameters are represented with alphanumeric or hexadecimal strings. In this case,
when the ACK/ENTER button is pressed, in addition to flashing the square brackets that
enclose the value, the controller displays a cursor under the first character of the string.
With the ◄ and ► buttons it is possible to move the cursor under the character to be modified.
Subsequently, using the ▲ and ▼ buttons it is possible to modify the selected character. The
operation is to be repeated for all the characters to be changed.
Press ACK/ENTER to confirm or ESC/SHIFT to cancel the change.
Changing the parameters can be limited by means of four different protection levels, listed in
order of priority.
•SICES password.
•MANUFACTURER password.
•INSTALLER password.
•USER password.
If a password is equal to 0, it is considered "unassigned". By default, all passwords are set at
"0", except for the password for the SICES level.
Each level of protection allows you to view a subset of the controller’s parameters. It also
allows you to view the parameters associated with a lower protection level. For example, the
INSTALLER can view and modify all the parameters of his own protection level, but also those
associated with the USER level. Each level also allows you to change your password and the
passwords of the lower levels.
The SICES protection level also allows you to view and modify some critical system
configuration parameters. This password is not configurable, but is supplied together with the
controller.
If a passwordis lost, you can reconfigureit by logging in with the higherlevel password.
In case of loss of the "manufacturer" password, contact support.
To modify a password-protected parameter, first enter the required password in parameter
"0000 - Access code", found in the "1.1.1 Authentication" menu. To be able to access it, it
is necessary to enter the various menus and submenus following the path “PROGRAM →1
SYSTEM →1.1 Security →1.1.1 Authentication”. Use the ESC/SHIFT button to go back to
the upper menu, the ACK/ENTER button to enter a submenu.

RN200 user manual 13
The access code set remains valid for about 10 minutes from the end of programming. After
this period, the access code must be reset to access programming again.
After authenticating with a password, it is possible to modify or reset it in the “PROGRAM →
1 SYSTEM →1.1 Security →1.1.2 Password” menu
The protections and alarms are generally configurable by means of specific parameters. As a
rule, the trip time associated with the protection can also be configured.
INFORMATION! By setting the tripping time equal to 0, the protection is disabled.

oERROR-PASSIVE: there are anomalies (errors) but the communication is
still working.
oBUS-OFF: the board has disconnected from the bus due to too many errors.

RN200 user manual 17
The communication error counters. The instantaneous counters of
transmission/reception errors and the maximum values reached by them are
displayed. It is possible to reset the maximum values (and at the same time force the
exit from the BUS-OFF state) by pressing the ACK/ENTER and ESC/SHIFT buttons
simultaneously for 5 seconds. Since there are two CAN interfaces, you must first
select the desired CAN interface and then reset the counters: to select an interface
press the ACK/ENTER key and use the ▲ and ▼ keys.
Internally, RN200 uses a third CAN interface for communication between its microcontrollers.
If necessary, the status of the third interface can also be displayed by activating bit 8 of
parameter P.0495.
These pages are dedicated to the display of the generic states acquired through the digital
inputs, configured with the functions DIF.3201 and DIF.3202 (page 1), DIF.3203 and DIF.3204
(page 2), DIF.3205 and DIF.3206 (page 3).
The page uses one row for each configured input. If more than 9 inputs are configured on each
page, the controller displays them all by rotating them (9 at a time) every two seconds: holding
the ESC/SHIFT button stops rotation. If there are no inputs configured on a page, the page is
not displayed.
On each row, the controller shows the text configured for the digital input and the logical status
of the input.
If the DIF.3202, DIF.3204 and DIF.3206 functions are used, when the input is activated, the
controller forces the display of the relative page.
The page S.11 displays the status of:
The digital inputs of the controller.
The analogue inputs used as digital (dashes are displayed if they are not used as
digital inputs).
Virtual digital inputs.
The page S.12 is displayed only if DITEL modules havebeen configured. It displays the status
of the digital inputs acquired by the DITEL modules. If a DITEL module does not communicate
correctly, the controller displays dashes instead of the state of the inputs.
By pressing the ACK/ENTER button, the inputs can be shown in three different ways:
LOGICAL STATE: the controller shows the logic level of the input (active or inactive)
used in the management of the operating sequence.
PHISICAL STATE: the controller shows the electrical level (active or inactive, or high
or low) actually present on the input; it can be opposite to the corresponding logical
state. It is displayed in REVERSE.
BY FUNCTION: the controller shows a list of the functions actually associated with
the digital inputs, displaying the logical status (1/0) relating to each function,
regardless of the input actually associated with the functions. If more than 8 functions
are used for the digital inputs, the controller displays them all by rotating them (8 at a
time) every two seconds: holding the ESC/SHIFT button stops rotation.
The page S.13 displays the status of the digital outputs of the controller.

The page S.14 is displayed only if DITEL modules havebeen configured. It displays the status
of the digital outputs of the DITEL modules. If a DITEL module does not communicate
correctly, the controller displays dashes instead of the state of the outputs.
By pressing the ACK/ENTER button, the inputs can be shown in three different ways:
LOGICAL STATE: the controller shows the logic level of the output (active or inactive)
used in the management of the operating sequence.
PHISICAL STATE: the controller shows the electrical level (active or inactive, or high
or low) actually present on the output; it can be opposite to the corresponding logical
state. It is displayed in REVERSE.
BY FUNCTION: the controller shows a list of the functions actually associated with
the digital outputs, displaying the logical status (1/0) relating to each function,
regardless of the output actually associated with the functions.If morethan8functions
are used for the digital outputs, the controller displays them all by rotating them (8 at
a time) every two seconds: holding the ESC/SHIFT button stops rotation.
The page S.15 displays the electrical value of the analogue inputs of the controllers
(connectors JU, JK and JJ), including the emergency stop (EM-S). By pressing the
ACK/ENTER button you can view the inputs in two different ways:
PHISICAL STATE: the measurement in VDC is displayed for each input.
PER FUNZIONE: the controller shows a list of the functions actually associated with
the analogue inputs, displaying the relative value acquired in VDC, regardless of the
input actually associated with the functions. If more than 8 functions are used for the
analogue inputs, the controller displays them all by rotating them (8 at a time) every
two seconds: holding the ESC/SHIFT button stops rotation.
The page S.16 is displayed only if DITHERM or DIGRIN modules have been configured. In
the left part it shows the type of module actually connected (DIGRIN, DITHERM or "DITEMP"
if the module does not communicate correctly). On the right side it shows the temperatures
acquired by the modules. They can be replaced by:
“------“: if the expansion module does not transmit the measurement.
“OPEN”: if the expansion module signals that the sensor is disconnected.
“+OVER”: if the module signals that the input signal is too high, a symptom of a fault.
“-OVER”: if the module signals that the input signal has a too low value, a symptom of
a fault.
The page S.17 is displayed only if DIVIT modules have been configured. On the right side it
shows the measurements acquired by the modules (without any conversion). They can be
replaced by:
“------“: if the expansion module does not transmit the measurement.
“OPEN”: if the expansion module signals that the sensor is disconnected.
“+OVER”: if the module signals that the input signal is too high, a symptom of a fault.
“-OVER”: if the module signals that the input signal has a too low value, a symptom of
a fault.
The page S.18 normally shows the percentage value currently associated with the two
analogue outputs of the controller. Pressing the ACK/ENTER button, the controller shows the
outputs by function: the controller shows a list of the functions actually associated with the
analogue outputs, displaying the analogue value for each function, regardless of the output
actually associated with the functions. If more than 8 functions are used for the analogue
