Instrument
XR80D
shall be
mounted on a DIN rail.
The temperature range
allowed for correct operation
is 0
÷
60 °C. Avoid places
subject to strong vibrations,
corrosive gases, excessive
dirt or humidity. The same
recommendations apply to
probes. Let air circulate by the
cooling holes.

ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross
section up to 2,5 mm
2
. Before connecting cables make sure the power supply complies
with the instrument’s requirements. Separate the probe cables from the power supply
cables, from the outputs and the power connections. Do not exceed the maximum current
allowed on each relay, in case of heavier loads use a suitable external relay.
9.1
PROBE CONNECTION
The probes shall be mounted with the bulb upwards to prevent damages due to casual
liquid infiltration.

HOW TO USE THE HOT KEY
10.1
HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)
1.
Program one controller with the front keypad.

o
key; the
"uPL"
message appears followed a by flashing
“End”
3.
Push “
SET”
key and the
End
will stop flashing.
4.
Turn OFF the instrument remove the
“Hot Key”,
then turn it ON again.
NOTE
: the “
Err
” message is displayed for failed programming. In this case push again
o
key if you want to restart the upload again or remove the “
Hot key
” to abort the operation.
10.2
HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY (DOWNLOAD)
1.
Turn OFF the instrument.
2.
Insert a
programmed “Hot Key” into the 5 PIN receptacle
and then turn the
Controller ON.
3.
Automatically the parameter list of the
“Hot Key”
is downloaded into the Controller
memory, the “
doL
” message is blinking followed a by flashing
“End”.
4.
After 10 seconds the instrument will restart working with the new parameters.
5.
Remove the
“Hot Key”.
.
NOTE
the message “
Err
” is displayed for failed programming. In this case turn the unit off
and then on if you want to restart the download again or remove the “
Hot key
” to abort the
operation.
11.
ALARM SIGNALS
Message
Cause
Output
“EE”
Data or memory failure
“P1”
Probe failure
Output according to par. “Con” and “COF”
“HA”
Maximum temp. alarm Output unchanged.
“LA”
Minimum temp. alarm
Output unchanged.
11.1
ALARM “EE”
The instrument is provided with an internal check verifying memory integrity. Alarm “
EE
”
flashes when a failure in the internal memory is detected. In such case call the service.
11.2
ALARM RECOVERY
Probe alarm “
P1
” start some seconds after the fault in the related probe; it automatically
stops some seconds after the probe restarts normal operation. Check connections before
replacing the probe.
Temperature alarms “
HA
” and “
LA
” automatically stop as soon as the thermostat
temperature returns to normal values and when defrost starts.
