Protections and alarms
GLT80TDC is electronically protected against a
number of possible dysfunctions and failures:
• Battery discharge.
• 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: it operates when
the compressor speed drops below the set
up speed, or when the current drawn in is
excessive, and thus preventing the appliance
from operating under overload conditions that
may cause otherwise refrigeration overload or
compressor failure.
• Electronic driver overheat: if the temperature
of the electronic components of the control
becomes too high, an internal sensor will stop
the unit.
In case of overheating, one automatic attempt
to restart the compressor is allowed. In case of
battery protection, there is no limit of automatic
attempts to restart. In case of any other
protection occurring, there will be two automatic
attempts to re-start the compressor.
Once the sequence of automatic attempts to
restart the compressor is finished, the unit will
remain permanently unable to operate until
switched off and on again from the power
supply. The intervention of the thermostat during
the sequence of automatic restart attempts
interrupts and resets the sequence.
