Only one device for each LAN has to be connected to the RS485 connection.
The Adr parameter is the number to identify each electronic board. Address duplication is not
permitted, in this case the synchronized defrost and the communication with monitoring system is not
guaranteed (the Adr is also the ModBUS address).
5.7 DIGITAL INPUTS
1) The terminals from [30] to [33] are all free of
voltage;
2) Use shielded cable for distance higher than one
meter;
For each input, has to be configured: the polarity of
activation, the function of the input and the delay of
signaling.
The parameters to perform this configuration are i1P, i1F, i1d respectively for polarity, functioning and
delay. The i1P can be: cL = active when closed; oP = active when opened. The i1F parameter can be:
EAL = external alarm, bAL = serious lock alarm, PAL = pressure switch alarm, dor = door switch, dEF =
external defrost, AUS = auxiliary activation command, LiG = light activation, OnF = board On/OFF, FHU
= don’t use this configuration, ES = day/night, HdY = don’t use this configuration. Then there is i1d
parameter for delay of activation. For the others digital inputs there are a set of the same parameters: i2P,
i2F, i2d, i3P, i3F, i3d.
5.8 ANALOG OUTPUT
• Selectable between 4 to 20mA and
0 to 10Vdc.
• Use CABCJ15 to perform the connections
It’s located near the terminal [39] on a 2-pin connector. It’s possible to use the output to control anti-sweat
heaters through a chopped phase controller XRPW500 (500watt) or family XV...D or XV...K.
6. USER INTERFACE
6.1 ICONS
With icon ON the output is
active, while with blinking
icon there is a delay.
MEASUREMENT UNIT
°C, Bar and (time) are
ON depending on the
selection.
DURING PROGRAMMING: blink the measurement units of temperature and pressure
6.2 KEYBOARD COMMANDS
Single commands:
Press and hold for 3 sec the defrost button
Press for 3 sec the ON/OFF button (if the function is enabled).
Press for 3 sec the ON/OFF button (if the function is enabled).
Press and hold for about 3 sec to lock (Pon) or unlock (PoF) the keyboard.
Pressed together to exit from programming mode or from menu; on submenus rtC
and EEV this combination allow to come back to previous level.
Pressed together for 3 sec allow to access to first level of programming mode.
6.3 HOW TO MODIFY THE SET POINT FOR AIR TEMPERATURE REGULATION
The thermostat set point is the value that will be used to regulate the air temperature. The regulation
output is controlled by the electronic valve or by the relay.
Press SET button for 3 sec, the measurement units will blink
together.
With the arrows it’s possible to change the value within the LS
and US parameters value.
By pressing SET it is possible to confirm the value that will blink
for about 2 sec.
In any case, it is possible to wait for about 10 sec to exit. In order to show the air temperature set is
sufficient to press and release the SET button, the value is displayed for about 60 sec.
7. HOW TO PROGRAM THE PARAMETERS (PR1 AND PR2)
The device provide 2 programming levels: Pr1 with direct access and Pr2 protected with a password
(intended for experts).
Press and hold for about 3 sec to have access to the first
programming level (Pr1).
Select the parameter or submenu using the arrows.
Use the arrows to modify the value.
Press SET key: the value will blink for 3 sec, and then the
display will show the next parameter.
Instantaneous exit from the programming mode, otherwise wait
for about 10 sec (without press any button).
7.1 HOW TO HAVE ACCESS TO “PR2”
To enter Pr2 programming menu:
1. Access to a Pr1 menu by pressing both SET+DOWN keys for 3 sec, the first parameter label will
be showed;
2. Press DOWN key till the Pr2 label will be showed, then press SET;
3. The blinking PAS label will be showed, wait some seconds;
4. Will be showed “0 - -” with blinking 0: insert the password [321] using the keys UP and DOWN and
confirming with SET key.
GENERAL STRUCTURE: The first two item rtC and EEV are related to submenus with other
parameters.
• SET+UP keys on rtC or EEV submenus allow coming back to parameter list,
• SET+UP keys on parameter list allow immediate exit.
7.2 HOW TO MOVE PARAMETER FROM PR1 TO PR2 AND VICE VERSA
Enter on Pr2; select the parameter; press together [SET + DOWN]; a left side LED ON gives to the
parameter the presence on Pr1 level, a left side LED OFF means that the parameter is not present on
Pr1 (only Pr2).
8. FAST ACCESS MENU
This menu contains the list of probes and some values that are automatically evacuate by the board such
as the superheat and the percentage of valve opening. The values: nP or noP stands for probe not present
or value not evacuate, Err value out of range, probe damaged not connected or incorrectly configured.
Entering
fast access
menu
By press and release the UP arrow. The duration of the menu
in case of inactivity is about 3 min.
The values that will be showed depend on the configuration of
the board.
