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.
9.1
PROBE CONNECTIONS
The probes 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. Place the defrost
termination probe among the evaporator fins in the coldest place, where most ice is
formed, far from heaters or from the warmest place during defrost, to prevent
premature defrost termination.
10
TTL SERIAL LINE
The TTL connector allows, by means of the external module TTL/RS485, to connect
the unit to a network line
ModBUS-RTU
compatible as the
dIXEL
monitoring system
XJ500 (Version 3.0). The same TTL connector is used to upload and download the
parameter list of the “
HOT KEY
“. These instruments can be ordered with direct serial
output
RS485
(Optional).
11
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.
11.1
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.
11.2
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
”.

The alarm message is displayed until the alarm condition is recovery.
All the alarm messages are showed alternatively.
12.1
SILENCING BUZZER / ALARM RELAY OUTPUT
If “
tbA = yES
”, once the alarm signal is detected the buzzer and the relay are is
silenced by pressing any key.
If “
tbA
=
no
”, only the buzzer is silenced while the alarm relay is on until the alarm
condition recovers.
12.2
ALARM RECOVERY
Probe alarms : “
P1
” (probe1 faulty), “
P2
” and “
P3
” automatically stop 10s after the
probe restarts normal operation. Check connections before replacing the probe.
Temperature alarms “
tAL
” automatically stop as soon as the thermostat temperature
returns to normal values.
Temperature alarm “
tAL
” automatically stops as soon as the thermostat temperature
returns to normal values and when defrost is started.
Alarms “
EA”, “PAL”
and
“dEA”
recover as soon as the digital input is disabled.
