COMPRESSORSCOMPRESSORS
Select thermostat delay 3 minutes for improved starting.
Click “Apply”. The FDC1 electronic driver is now programmed and ready to drive the compressor.
From the top menu, save the current conguration if desired.
To program another FDC1 unit, plug it in, apply current conguration or return to step 6 to
change conguration.
Click exit to nish.

GD30FDC User Manual
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 congured 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:
In case of an alarm display, if the FDC1 electronic dr
iver is connected as a slave to the appliance’s
Electronic Integral Manager (EIM) through the SPI, a digital alarm code will be transmitted to the
EIM, which in turn will manage the information for displaying and acting purposes.
