TTL SERIAL LINE
The TTL connector allows to upload and download the parameter list of the “
HOT KEY
“.
12.
USE OF THE PROGRAMMING “HOT KEY “
The Wing units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal
memory to the
“Hot Key”
and vice-versa.
12.1
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 Wing ON.
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”
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.
12.2
UPLOAD (FROM THE INSTRUMENT TO THE “HOT KEY”)
1.
Turn OFF the instrument by means of the ON/OFF key 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”
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
Messag
e
Cause
Outputs
“P1” Thermostat probe failure
Alarm output ON; Compressor output
according to parameters “COn” and “COF”
“P2” Evaporator probe failure
Alarm output ON; Other outputs unchanged
“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
“dA” Defrost timeout alarm
Alarm output ON; Other outputs unchanged
“dAL” Door switch alarm
Alarm output ON; Other outputs unchanged
“EAL” External alarm
Alarm output ON; Other outputs unchanged
“BAL” Serious external alarm
Alarm output ON; Other outputs OFF
“rtc” Real time clock alarm
Alarm output ON; Other outputs unchanged;
Defrosts according to par. “
IdF
”
“PAL” Pressure switch alarm
Alarm output ON; Other outputs OFF
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.
13.1
SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing any key.
13.2
“EE” ALARM
The Dixell 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.
13.3
ALARM RECOVERY
Probe alarms : “
P1
” (probe1 faulty) and “
P2
”; they automatically stop 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.
Door switch alarm “
dA
” stop as soon as the door is closed.
External alarms “
EAL
”, “
BAL
” stop as soon as the external digital input is disabled “
PAL
”
alarm is recovered by switching OFF the instrument.
