Alarm Signals - dixell XR06CX Mode D'emploi

dIXEL
SERIOUS ALARM MODE (i1F = bAL)
When the digital input is activated, the unit will wait for "did" delay before signalling the "CA" alarm
message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-
activated.
PRESSURE SWITCH (i1F = PAL)
If during the interval time set by "did" parameter, the pressure switch has reached the number of
activation of the "nPS" parameter, the "CA" pressure alarm message will be displayed. The
compressor and the regulation are stopped. When the digital input is ON the compressor is always
OFF. If the nPS activation in the did time is reached, switch off and on the instrument to restart
normal regulation.
AUXILIARY OUTPUT SWITCHING (i1F =AUS)
With oA3 = AUS and i1F = AUX it switches the fourth relay (22-23).
START DEFROST (i1F = dFr)
It starts a defrost if there are the right conditions. After the defrost is finished, the normal regulation will
restart only if the digital input is disabled otherwise the instrument will wait until the "MdF" safety time
is expired.
INVERSION OF THE KIND OF ACTION: HEATING-COOLING (i1F = Htr)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
ENERGY SAVING (i1F = ES)
The Energy Saving function allows to change the set point value as the result of the SET+ HES
(parameter) sum. This function is enabled until the digital input is activated.
DIGITAL INPUTS POLARITY
The digital input polarity depends on the "i1P" parameter.
i1P=CL: the input is activated by closing the contact.
i1P=OP: the input is activated by opening the contact
8. Installation and mounting
T620 keyboard shall be mounted on vertical panel, in a 150x31 mm hole, and fixed using two screws
3 x 2mm. To obtain an IP65 protection grade use the front panel rubber gasket (mod. RG-L).
∅
V620 keyboard shall be mounted on vertical panel, in a 72x56 mm hole, and fixed using two screws
3 x 2mm. To obtain an IP65 protection grade use the front panel rubber gasket (mod. RGW-V).
CX620 keyboard shall be mounted on vertical panel, in a 29x71 mm hole, and fixed using the special
bracket supplied.
The controller XW60K shall be mounted in a din rail
It must be connected to the keyboard by means of a two-wire cable (∅ 1mm). The temperature range
allowed for correct operation is 0 - 60 °C. Avoid places subject to strong vibrations, corrosive gases,
excessive dirt or humidity. The same recommendations apply to probes. Let the air circulate by the
cooling holes.
XW60K – 8 DIN CASE - DIMENSIONS
9. Electrical connections
XW60K is provided with screw terminal blocks to connect cables with a cross section up to 2,5 mm
the RS485(optional) and the keyboard. Connecting other inputs, power supply and relays, XW60K is
provided with Faston connections (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/RS485 Serial line
The TTL connector allows, by means of the external module TTL/RS485 (XJ485CX), 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".
The instruments can be ordered wit the 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
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".

12. ALARM SIGNALS

Message Cause
"P1" Thermostat probe failure
"P2" Evaporator probe failure
"P3" Probe 3 probe failure
"P4" Probe 4 probe failure
"HA" Maximum temperature alarm
"LA" Minimum temperature alarm
"HA2" Condenser high temperature
"LA2" Condenser low temperature
"dA" Door open
"EA" External alarm
"CA" Serious external alarm (i1F=bAL) All outputs OFF.
"CA" Pressure switch alarm (i1F=PAL) All outputs OFF
"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.
12.1 SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing any key. Buzzer is mounted
in the keyboard and it is an option.
12.2 "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.
12.3 ALARM RECOVERY
Probe alarms : "P1" (probe1 faulty), "P2" and "P3"; they automatically stop 10s after the probe restarts
normal operation. Check connections before replacing the probe.
Temperature alarms "HA", "LA" "HA2" and "LA2" automatically stop as soon as the temperature
returns to normal values.
Alarms "EA" and "CA" (with i1F=bAL) recover as soon as the digital input is disabled.
Alarm "CA" (with i1F=PAL) recovers only by switching off and on the instrument.
