7. ELECTRICAL CONNECTIONS
The instrument is provided with faston 2.8mm for analogue inputs. Relays and power supply
have a Faston connection (6,3mm). Heat-resistant cables have to be used. 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.
N.B. Maximum current allowed for all the loads is 20A.
7.1 PROBE CONNECTIONS
The probe shall be mounted with the bulb upwards to prevent damages due to casual liquid
infiltration. It is recommended to place the thermostat probe away from air streams to correctly
measure the average room temperature.
8. 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.
8.1 DOWNLOAD (FROM THE “HOT KEY” TO THE INSTRUMENT)
1. Turn OFF the instrument by means of the ON/OFF key, remove the TTL serial cable if
present, 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”, 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”.
9. ALARM SIGNALS
Mess. 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
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 “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.
9.2 ALARM RECOVERY
Probe alarms : “P1” (probe1 faulty), “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.
