1 GENERAL WARNING
1.1 Please read before using this manual
This manual is part of the product and should be kept near the instrument
for easy and quick reference.
The instrument shall not be used for purposes different from those
described hereunder. It cannot be used as a safety device.
Check the 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.
The instrument must not be opened.
In case of failure or faulty operation send the instrument back to the
distributor or to “Dixell s.r.l.” (see address) with a detailed description of
the fault.
Consider the maximum power of the load (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.
Fit the instrument away from heater sources and be sure to have
sufficient air flow to allow a good thermal exchange.
2 GENERAL DESCRIPTION
The models XV110K (1000Watt) and XV150K (5000Watt) are speed
controllers suitable for industrial and refrigeration applications in particular to
control the air flow in condensing and evaporating and condensing processes.
The regulation is made through 4 trimmers placed on the board while the load
control is executed by a TRIAC with phase cut.
The controllers are configurable to start the fans at the maximum speed for 10
seconds. The input signal can be ordered choosing among temperature probe
NTC, 4/20mA or 0/1Vdc and 0/10Vdc signals.
3 OPERATING
Example of functioning with a condensing unit (direct): the probe must be fit
where the sensor detects the most critic place of the condenser. Calibrate the
Set trimmer to the temperature (or pressure) at which the fan runs at the
maximum speed. Then calibrate the Diff trimmer to set the temperature (or
pressure) differential at which the fan is stopped. E.g. if the Set is 40°C
and the Diff is 10°C, when the temperature is above 40° the fan runs at
maximum speed, if the temperature is between 30° and 40° the fan
speed is proportionally controlled. Below 30°C the fan is stopped.
4 COMMANDS
Trimmer SET: by turning clockwise this trimmer, the set is changed from
the minimum to the maximum value (see table of the default
values).
Trimmer differential: by turning clockwise this trimmer, the differential is
changed from the minimum to the maximum value (see table of
the default values).
Trimmer V min: by turning clockwise this trimmer, the minimum fan
speed can be changed from 0 to 50% of the maximum voltage
output.
Trimmer Cut Off: by turning clockwise this trimmer, the fan cut-off can be
changed from 10 to 30% of the maximum voltage output.
Green led: this led signals when the load is being controlled.
5 DIRECT AND INVERSE CONTROL
Direct action: if the input signal increases, the voltage output
proportionally increases (condensing or cooling applications).
If the input signal is higher than the Set, the output signal is 230 Volt (fans
are running at the maximum speed). When the signal decreases and
enters the range between the Set and Set-Diff the output signal follows
the temperature variation. Below the Set-diff value the output signal is
always 0V (if no Vmin has been set).
Inverse action: if the input signal increases, the voltage output
proportionally decreases (evaporating or heating applications).
If the input signal is lower than the Set, the output signal is 230 Volt (fans
are running at the maximum speed). When the signal increases and
enters the range between the Set and Set+Diff the output signal follows
the temperature variation. Above the Set+diff value the output signal is
always 0 Volt (if no Vmin has been set).

6 CONTROLS
6.1 Minimum fan speed
To avoid that the fan can be damaged with low voltage output, it is possible set
a minimum voltage output (minimum speed). The range is selectable from 0 to
50% of the power supply.
6.2 Cut-off function
The Cut-off function drastically reduces the output to 0V, when the voltage on
the load is lower than a percentage set with this trimmer. The range is
selectable from 10 to 30% of the power supply. Example: if set to the middle
position (15%), when the voltage on the load is lower than 15% of 230V, the
fan immediately are stopped.
6.3 MAXIMUM FAN SPEED AT START UP (J2)
By closing the external jumper J2, each time that the fan restarts, it will run at
maximum speed for 10 seconds.
6.4 Trigger signals (Master / slave J3)
To control different loads having more than the rating plate of the instrument,
the trigger out can be used to connect another speed controller provided with
the trigger in terminals.
MASTER
By closing the 2-3 position of the jumper J3 the instrument is set as master,
therefore the control function is repeated through terminals 5 and 6 to a slave
instrument.
SLAVE
By closing the 1-2 position jumper J3 the instrument is set as slave, therefore it
can receive the trigger signal to the terminals 7 and 8, the controller will follow
exactly the function executed by the master instrument itself.
When using the three phases power supply, both the Master and the Slave
must be connected to the same phase.
6.5 Changing the action type with current or
voltage input models (J2)
All the instruments having a 4/20mA or 0/1Vdc and 0/10Vdc inputs, can
change the action by means of J2 jumper. Jumper closed = direct action
(condensing), jumper open = reverse action (evaporating).
7 ANTI CONDENSING KIT (OPTIONAL)
This heater element, called XV –ACK, can be used to warm the air inside the
IP55 box, in order to permit the correct functioning of the instrument when it is
used in critical applications up to –40°C below zero. In this case connect the
element on the faston near the power supply terminals 4 and 5. The order
code for this optional heater element is DG 000001 00.
8 INSTALLING AND MOUNTING
The instruments shall be mounted on panel. The temperature range allowed
for correct operation is 0 - 60 °C. By using the heater element XV-ACK, the
temperature of the environment where the instrument is placed, can reach –40
°C
Avoid places subject to strong vibrations, corrosive gases, excessive dirt or
humidity. The same recommendations apply to probes. Let air circulate nearby
the instrument.
9 ELECTRICAL WIRING
The instruments are provided with Kress screw terminals to connect the input
signals and Faston 6.3mm to connect the power supply and the load. The
6.3mm faston placed on the heat sink must be connected to the ground. The
two 6.3mm faston terminals near the power supply terminals 4 and 5, can be
used to connect the heater XV-ACK when the temperature of the outside
environment is too low.
Before connecting cables make sure the power supply complies with the
instrument’s requirements. Separate the input signal cable from the power
supply cables, from the outputs and the power connections. Do not exceed the
maximum current allowed on the output terminals.
