1. GENERAL WARNING
1.1 PLEASE READ BEFORE USING THIS MANUAL
This manual is partof the product and should be kept neartheinstrumentfor easy and quick reference.
The instrument shall not be used for purposes different from those described hereunder. It cannot beused
as a safety device.
Checkthe application limits before proceeding.
1.2 SAFETY PRECAUTIONS
Check the supply voltage is correct before connecting the instrument.
Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden
temperature changes with high atmospheric humidity to prevent formation of condensation
Warning: disconnect all electrical connections before any kind of maintenance.
Fit the probe where it is not accessible by the End User. The instrument must not be opened.
In case of failure or faulty operation send the instrument back to the distributor (see address) with a
detailed description of the fault.
Consider the maximum current which can be applied to each relay (see Technical Data).
Ensure that the wires for probes, loads and the power supply are separated and far enough from each
other, without crossing or intertwining.
In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with
inductive loads could be useful.
2. GENERAL DESCRIPTION
The XM664K is microprocessor controller suitable for medium and low temperature multiplexed cabinet
applications composed of as many as 8 sections. This makes it possible to create a LAN (local area network)
made up of the instruments which, depending on the programming, can operate as single controllers or
managing the controls which arrive from one or more sections. The XM664K is equipped with 6 relay outputs
which control the compressor, the defrost 1 and 2 (which can be either electric or with hot gas, the evaporator
fans, the lights and an ON/OFF output. It is supplied with three NTC probe inputs, one for thermostating, one for
temperature control at the end of defrost on evaporator 1 and one for end of defrost 2 control. There are also
two digital inputs which can be configured by parameters.
The two LAN outputs provide an easy connection between the various controllers while the TTL connector
programsthecomplete parameter list by means ofa programming keycalled “Hot Key”.
3. CONTROLLING LOADS
3.1 COMPRESSOR
The regulation is performed according to the temperature measured by the thermostat probe with a positive
differential from the set point: if the temperature increases and reaches set point plus differential the compressor
is started and then turned off when the temperature reaches the set point value again.
In case of fault in the thermostat probe the start and stop of the compressor are timed through parameters Con
andCoF.
3.2 DEFROST
There are three types of defrost available that can be selected with the parameter tdF: defrost with electric
heater (tdF=EL), with hot gas (tdF=in) or disabled (tdF=oFF). When defrost is over, the dripping time starts,
which is managed by the parameter Fdt.
Management of two defrosts is configured by parameters dMo, dd1, dEM and dEn. In particular:
dMo Defrost 1-2 management mode: (ind; 2-1; dEL) if dMo=ind defrost 1 e 2 managements are independent;
if dMo=2-1 activation of defrost 2 entails activation of defrost 1; if dMo=dEL activation of defrost 2 entails
activation of defrost 1 with delay set by parameter dd1;
dd1 Defrost 1 activation delay compared to defrost 2: (0 to 255 min) as previously mentioned, it describes
the activation delay of defrost 1 after activation of defrost 2 if dMo=dEL;
dEM Defrost synchronisation in LAN: (ind; Sin) if dEM=ind the end of defrosts is independent. If dEM=Sin,
the end of defrosts is synchronised;
dEn Synchronisation of local defrost end (def1 and def2): (ind; Sin) if dEM=ind the end of defrosts is
independent. If dEM=Sin, the end of defrosts is synchronised.
The start of a defrost cycle can be controlled locally (manual activation by the keyboard, digital input or at the
end of the time interval). Otherwise the command can arrive from any controller inserted in the LAN. In this last
case, the controller will start a defrost cycle and will bring it to the end following the indications present in its
programming parameters. But at the end of the cycle, it will wait for all the controllers present in the LAN to finish
before returning to normal temperature regulation.
3.3 CONTROL OF EVAPORATOR FANS
The fan control mode is selected by means of the FnC parameter:
FnC = C_n: fans will switch ON and OFF with the compressor and not run during defrost;
FnC = o_n: fanswill run even if the compressor isoff, and not run during defrost.
After defrost, there is a timed fan delay allowing for drip time, set by means of the Fnd parameter:
FnC = C_Y: fans will switch ON and OFF with the compressor and run during defrost;
FnC = o_Y: fans will run continuously also during defrost.
An additional parameter FSt provides the setting of temperature, detected by the evaporator probe, above which
the fans are always OFF. This is used to make sure circulation of air only if his temperature is lower than set in
FSt.

8. ELECTRICAL CONNECTIONS
The XM664K power modules are provided with screw terminal block to connect cables with a cross section up
to 2.5 mm2. Relays and power supply have Fast-on type connection (6.3 mm). 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.
8.1 PROBE CONNECTION
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 fromthewarmest place during defrost, to prevent premature defrost termination.
9. TTL SERIAL LINE
The TTL connector allows, by means of the external module XJ485, to connect the unit to a network line
ModBUS-RTU compatible as the dIXEL monitoring system XWEB.
The same TTL connector is used to upload and download the parameter list of the “Hot Key “.
10. HOW TO USE THE HOT KEY
10.1 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.

11. ALARMS
The alarm signals displayed on the keyboard can be divided into 2 groups:
1. Local alarms, including all the alarms relating to the section directly controlled by the keyboard.
2. Remote alarms, including all those alarms relating to the LAN.
The signal on the display remains until the alarm condition has ceased. All of the alarm signals flash, alternating
with the probe temperature, except for "P1" which is always flashing.
The "EE" alarm can be cancelled by pressing any key during the alarm signal. Then the message “rSt” is
displayed for about 3s before going back to normal functioning.

11.2 REMOTE ALARMS
Mess. Cause
“ASn” Section nis in alarm, with n= serialLAN address ("LAN"parameter). this alarmis displayed onlyif
thekeyboard isin “ALL” mode. Thisis a genericindication ofthestate of alarm. To have more
detailed information, set the keyboard so that it controls that specific section.
“nLn” No link alarm (no communication) with section n (“Lan”parameter)
“nLn” No link alarm (no communication) while a remote probe is viewed. This alarm appears only if the
LdS parameter of the section is set at "y".
“rPE” Remote viewer error. More than one keyboard has been set for remote control
11.3 BUZZER SILENCING AND ALARM EXIT
Once the alarm signal has been detected, the buzzer and alarm exit can be deactivated by pressing any key.
However the signal on the display remains until the alarm condition has ceased. It is possible to inhibit the alarm
relay deactivation by setting the parameter tbA=n. In this way the alarm relay remains active as long as the
alarm condition lasts.
The signal buzzer is found in the keyboardT640.
11.4 “EE” ALARM
The instruments of the Dixell series are equipped with an internal control which checks the integrity of the data.
The flashing “EE” alarm which alternates with the temperature signals the presence of a data anomaly. .
11.5 MODE FOR CEASING ALARMS
The probe alarms “P1”, “P2” and “P3” are triggered about 10 sec after the probe failure. They automatically
cease 10 sec after the probe goes back to regular functioning. Before replacing a probe, it is recommended to
check the connections.
The temperature probes “HA” and “LA” automatically cease as soon as the thermostat temperature goes back
to normal, when defrost starts or when the door opens.
The No link alarms “nLn”and “nLn”cease automatically as soon as correct communication is re-established
between the sections
The digital input alarms “EAL” and “BAL” cease automatically when the input is deactivated.
