13. RS485 SERIAL LINE
XM660K/XM669K is provided of a direct RS485 connection that allow the unit, to be linked to a network
line ModBUS-RTU compatible with all dIXEL monitoring system.
14. USE OF THE PROGRAMMING "HOT KEY"
The XM units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the
"Hot Key" and vice-versa through a TTL connector.
14.1 DOWNLOAD (FROM THE "HOT KEY" TO THE INSTRUMENT)
1.
Turn OFF the instrument by means of the ON/OFF key ,insert the "Hot Key" and then turn the
unit ON.
2.
Automatically the parameter list of the "Hot Key" is downloaded into the controller memory, the
"doL" message is blinking. After 10 seconds the instrument will restart working with the new
parameters. At the end of the data transfer phase the instrument displays the following
messages: "end" for right programming. The instrument starts regularly with the new
programming. "err" 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.
14.2 UPLOAD (FROM THE INSTRUMENT TO THE "HOT KEY")
When the XM unit is ON, insert the "Hot key" and push è key; the "uPL" message appears.
1.
2.
The UPLOAD begins; the "uPL" message is blinking.
3.
Remove the "Hot Key".
At the end of the data transfer phase the instrument displays the following messages:
"end " for right programming.
"err" for failed programming. In this case push "SET" key if you want to restart the programming
again or remove the not programmed "Hot key".

"EE" ALARM
The dIXEL instruments are provided with an internal check for the data integrity. Alarm "EE" flashes
when a failure in the memory data occurs. In such cases the alarm output is enabled.
15.2 ALARM RECOVERY
Probe alarms : "P1" (probe1 faulty), "P2", "P3", "P4", "P5", "P6"; they automatically stop 10s after the
probe restarts normal operation. Check connections before replacing the probe. Temperature alarms
"HA", "LA", "HAd", "LAd", "HAF", "LAF" automatically stop as soon as the thermostat temperature
returns to normal values or when the defrost starts. External alarms "EAL", "BAL" stop as soon as the
external digital input is disabled.
