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 M
AXIMUM 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.
