2.
Automatically the parameter list of the
“Hot Key”
is downloaded into the Wing memory, the
“
doL
” message is blinking. After 10 seconds the instrument will restart working with the new
parameters.
3.
Turn OFF the instrument remove the
“Hot Key”,
plug in the TTL serial cable, then turn it ON
again.
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.
8.2
UPLOAD (FROM THE INSTRUMENT TO THE “HOT KEY”)
1.
Turn OFF the instrument by means of the ON/OFF key and remove the TTL serial cable if
present; then turn it ON again.
2.
When the Wing unit is ON, insert the “
Hot key
” and push
o
key; the
"uPL"
message
appears.
3.
Push “
SET”
key to start the UPLOAD; the “
uPL
” message is blinking.
4.
Turn OFF the instrument remove the
“Hot Key”,
plug in the TTL serial cable, then turn it ON
again.
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
”.

ALARM SIGNALS
Message Cause
Outputs
“P1”
Thermostat probe failure
Alarm output ON; Compressor output according to
parameters “COn” and “COF”
“HA”
Maximum temperature alarm
Alarm output ON; Other outputs unchanged
“LA”
Minimum temperature alarm
Alarm output ON; Other outputs unchanged
“EE” Data or memory failure
Alarm output ON; Other outputs unchanged
The alarm message is displayed until the alarm condition is recovery.
All the alarm messages are showed alternating with the room temperature except for the “P1” which is
flashing. To reset the “EE” alarm and restart the normal functioning press any key, the “
rSt
” message is
displayed for about 3s.
9.1
SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing any key.
9.2
“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.
9.3
ALARM RECOVERY
Probe alarm
: “
P1
” (probe1 faulty), automatically stops 10s 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 or when the defrost starts.
