XM660K - XM670K
2/9
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
.

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.

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.
BEGIN
Press SET button for 3 sec, the measurement units will blink
together.
Value
modification
or
With the arrows it’s possible to change the value within the LS
and US parameters value.
EXIT
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).
ACCESS to
Pr1
Press and hold for about 3 sec to have access to the first
programming level (
Pr1
).
Select item
or
Select the parameter or submenu using the arrows.
Show value
Press
SET
button.
Modify
or
Use the arrows to modify the value.
Confirm and
store
Press
SET
key: the value will blink for 3 sec, and then the
display will show the next parameter.
EXIT
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 “

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
).

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.
