About the product
Many vehicles for transportation of goods or
recreation, such as trucks, caravans, boats, cars,
etc. are often equipped with cooling appliances.
The compressors for such mobile applications
must be designed to operate from a low voltage
DC power supply. These compressors must also
be compact in their dimensions, highly reliable
and yield high performances.
GD30FDC is an answer to the needs of users
requiring comfort and reliability in their
travelling, either on holidays, at work or in
any other circumstance where a DC powered
refrigerator is utilised. The GD30FDC is designed
to operate silently, eciently and reliably even up
to angles of tilt of 30º, working with refrigerant
R134a. Its design is based on the “D” series, which
has been successfully present in the market since
1984, and has had sales of 15 million units.
GD30FDC compressor is not designed for oroad mobile applications. If you are interested
in this type of mobile applications, it has to be
specically approved by the manufacturer.
GD30FDC can be powered at any voltage within
the 12 to 42V DC range, and is designed for
capillary tube expansion. Each unit is supplied
with a dedicated electronic driver (FDC1), which
features all the protections for both the battery
and the driver itself, including the compressor
motor. The driver automatically adjusts itself to
the voltage of the power supply.
Evaporation temperature range: -30ºC to +10ºC.
Condensation temperature range: up to 65ºC.
Pull-down peak: 70ºC.
Ambient temperature range: -10 to 55ºC (65ºC at
starting).
In case of ambient temperature lower than 0ºC,
an oil heater will be needed.
FDC1 electronic driver includes Smart Speed® as
programming option, which is a plug-in system
for automatically self adapting compressor speed
to current thermal load.
Smart Speed® reduces the number of thermostat
cycles by minimizing compressor speed,
enlarging on-time at every thermostat cycle,
so that start/stop energy loses are substantially
reduced. Lowest speed yields also highest
evaporating temperature, and so highest C.O.P
and lowest energy consumption. Pull-down is
done at maximum programmed speed, so pulldown time is very short with respect to xed
speed systems. No design parameters neither of
the compressor nor the appliance are required to
be programmed, so Smart Speed® can be easily
used in all appliances with no design eorts.
FDC1 electronic driver includes also Sleep and
Sleep Energy Saving as programming option,
which is a plug-in system specially conceived
for mobile air conditioners avoiding any other
electronic device. Sleep and Sleep Energy Saving
makes the air conditioner work for four hours
since start-up. Sleep Energy Saving makes the
compressor run at maximum programmed speed
during the rst hour, when highest cooling
capacity is needed, and lowers compressor speed
progressively to minimum velocity three hours
later. Maximum comfort and minimum energy
consumption is thus achieved.
GD30FDC starting capability is as low as 10V
under any balanced pressure. It also admits a
certain remaining dierential pressure when
thermostat o-time is abnormally short. For
improving even more the starting capability,
FDC1 electronic driver is supplied with a 3
minutes minimum thermostat o-time. The delay
is a programming option which can be easily
removed if no delay is preferred for any reason.
4 FRCC.PC.040.A1.02
The electronic control unit FDC1 is supplied with
the exclusive Serial Port Interface (SPI), featuring
a RJ11 telephone type connector. SPI allows the
electronic driver to be connected to a computer
for programming purposes using the FxC
programming package (hardware and software,
provided by the manufacturer upon request),
and allows the communication with an Electronic
Integral Manager of the appliance (EIM), and
making the compressor work in slave mode.
FDC1 also includes a 1 second lter at the
thermostat input to prevent the appliance from
wrong operation due to typical micro switching
produced by vibrations in those appliances that
t tilt switches at the thermostat circuit. So,
analogical ltering is not needed.
Wiring and Connections
General rules
GD30FDC must always be powered through
the dedicated electronic driver FDC1, which
is supplied with the compressor as a separate
device.
NEVER CONNECT THE COMPRESSOR’S HERMETIC
PINS (FUSITE) TO THE TERMINALS OF A BATTERY
OR ANY OTHER DC OR AC SOURCE DIRECTLY.
DO NOT TRY TO FIT AN ELECTRONIC DRIVER
OTHER THAN THE FDC1. THE COMPRESSOR WILL
NOT OPERATE AND IRREVERSIBLE DAMAGE MAY
OCCUR.
The FDC1 driver is directly connected to the
battery poles as well as to the compressor pins.
It checks battery voltage and adjusts itself to the
voltage value for proper compressor operation,
or switches itself o if the battery voltage is not
adequate. The driver also controls the compressor
speed.
ALWAYS RESPECT THE POLARITY OF THE BATTERY
WITH THE POWER INPUT TERMINALS OF THE
ELECTRONIC DRIVER.
The unit is protected against damage caused by
wrong polarity of the supply, The compressor will
not run correctly if it’s wrongly connected.
“-“ POWER INPUT TERMINAL OF THE ELECTRONIC
DRIVER SHOULD BE REFERRED TO THE CHASSIS
OF THE VEHICLE AS WELL AS THE APPLIANCE
FRAME*
A FUSE MUST BE PLACED BETWEEN THE “+” POLE
OF THE BATTERY OR DC POWER SUPPLY AND THE
“+” POWER INPUT TERMINAL OF THE ELECTRONIC
DRIVER*
12V SYSTEMS: 30A FUSE
24V SYSTEMS: 15A FUSE
42V SYSTEMS: 10A FUSE
In some special vehicles chassis is connected to
“+” terminal of the battery instead of “-“ terminal
(positive reference systems). In such cases “+”
should be understood as “-“ and vice-versa.
In systems powered by a variable DC source, the
fuse should be selected following the rules above
mentioned, considering the maximum voltage at
the variable DC Source.
Voltage drop in the
power leads
Table 1: Maximum length
of leads (m)
To avoid excessive voltage drop in the leads, their
length and cross section must be related to the
voltage supply as indicated in Table 1.

If any kind of connector or switch is placed
between the battery poles and the power
terminals of the electronic driver, its resistance
should be less than 10mΩ. If the resistance is

The FDC1 electronic driver features a terminal
board where all connections are made. The
terminal lay out is described in Figure 1:
Fig 2. Connection of the
FDC1 electronic driver to
the compressor
When connecting the electronic driver to the
compressor, any position of the connector
is possible under an electrical point of view.
However, in practice, the vertical position is not
possible because the electronic box cannot be
assembled. The connector should be rotated 120º
clockwise or counter clockwise with respect to
the vertical position as shown below.

The serial port interface (SPI)
Fig 3. SPI terminals
The electronic control unit FDC1 is supplied with
the exclusive Serial Port Interface (SPI), featuring
a RJ11 telephone type connector. This port
allows the electronic driver to be connected to
a computer for programming purposes using
the FxC programming package (hardware and
software) provided by the manufacturer upon
request. Optionally, the SPI can be congured to:
• Install a LED to display the intervention of any
alarm.
• Set up either the compressor speed or the
battery protection level, through physical
connections between IN1, IN2 and COM.
• Connect the electronic driver as slave to an
Electronic Integral Manager of the appliance with
serial communication capabilities (Rx, Tx and
COM), to allow working with variable speed. SPI
provides a 5 V output, limited to 25mA, to power
up the EIM.
Figure 3 Shows the RJ11 male connector which
can be plugged to the SPI and the usage of each
terminal in it.

Operating voltage
GD30FDC is designed to operate in a wide range
of DC voltages, supplied either by a battery or by
any other kind of ltered DC power supply.
DC VOLTAGE SUPPLY ALLOWED: 10V to 42.4V
Functional modes
• Standard (Default):
From the value of the applied voltage, the
electronic driver automatically decides the rated
voltage range of the supply. Three possible
ranges are considered:
12 to 14V: actual voltage is below 17V
24 to 28V: actual voltage is within 17 and 33V
36 to 42V: actual voltage is within 33 and 42.4V
• Special (programming option):
The compressor can be powered by a variable DC
source as, for instance, a photovoltaic panel, in
which the output voltage strongly depends on
the intensity of sunlight radiation. In these special
cases the driver should be programmed with
rated, minimum and maximum voltages. These
values should be within the allowable DC voltage
power supply (10 V to 42.4V).
Rated voltage and voltage limits are programmed
by the appliance manufacturer by means of a PC
connected through the serial port to the driver’s
Serial Port Interface, using the FxC programming
package provided by the manufacturer upon
request.

Battery protection system
Table 2. Limits of battery
protection parameters
There is a protection system for the battery that
• By programming:
prevents the compressor from operating if the
available voltage becomes too low. The battery
protection level should be set up as following:
Voltage limits for battery protection can be freely
set, by the customer for every system (12-14V,
24-28V, 36-42V or special) by means of the serial
or USB port of a PC connected to the SPI port of
the electronic driver using the FxC programming
package provided by the manufacturer upon
request. In that option cut-out and cut-in values
must respect the rule dened by Table 2.

is supplied by the manufacturer with standard
running mode and external control of the speed,
with minimum speed of 1,500 rpm and maximum
speed 3,500 rpm. Default running mode, options
and parameters can be changed to optimize
compressor performance for a given appliance,
by programming, connecting a PC to the SPI
by means of the FxC programming package
provided by the manufacturer upon request.
Running modes and options are:
• Standard mode:
· 1,500 rpm when the battery voltage is equal to
the cut-in voltage.
· Programmed xed speed when the battery
voltage is equal to or greater than the maximum
nominal voltage (14V, 28V and 42V for 12V, 24V
and 42V systems respectively).
· A linear function of the battery voltage in the
range between the cut-in and the maximum
nominal voltages.
This option is particularly useful for eutectic
plates systems.
Compressor speed is a xed programmed
value or switched externally from programmed
minimum and maximum value in four steps.
The switch should be connected to the SPI and
should remain plugged during compressor
operation.

Protections and alarms
GD30FDC is electronically protected against a
number of possible malfunctions and failures:
• Battery discharge: refer to point 5 for details.
• Fan over current: protects the compressor and
the electronic driver against fan over current due
to start or running overload, or short-circuit.
• Starting failure: if the running speed is not
achieved during the starting sequence, the unit
stops and retries the start up after one minute.
• Compressor overload: This protection operates
when the compressor speed drops below the
set up speed, or when the current drawn in is
excessive, thus preventing the appliance from
operating under overload conditions, causing
refrigerating overload or compressor failure.
• Electronic driver overheat: In case the
temperature of the electronic components of the
control becomes too high, an internal sensor will
stop the unit.
When the alarm is on, ten automatic attempts
to restart the compressor will be available.
In case of battery protection, the number of
automatic attempts to restart is unlimited.
Once the sequence of automatic attempts to
restart the compressor is nished, the unit will
remain permanently unable to operate until it
is switched o and on again from the power
supply. The intervention of the thermostat during
the sequence of automatic restart attempts
interrupts and resets the sequence.
The SPI can be congured in a way that a LED can
be connected between terminals 3 and 4 (see Fig.
2 in point 3) in order to display the intervention
of any alarm, and to identify its cause. The
visualisation consists of a sequence of ashes
of the LED repeating every 5 seconds, until the
cause of the alarm disappears. The code of the
ashing sequence corresponding to each alarm is
indicated in Table 6:
