Notes
This signal occurs when the transducer detects a flow pressure
over the set-factory parameter threshold (8) (default: 40 bar).
The pre-alarm state is exited with set_factory (8) – set_factory (b)
pressure (default 40 – 2 = 38 bar)
This signal occurs when the defrosting probe is absent and the
machine is set as heat pump
This signal occurs when the compressor intake transducer is
absent and the machine is set as heat pump
This signal occurs when the compressor flow transducer indicates
an intake pressure below the threshold set by the set_factory (9)
parameter in cooling mode (default 4 bar), set_factory(A) ion heat-
ing mode (default 2 bar). The pre-alarm state is exited when the
intake pressure exceeds the intervention set_factory(b) threshold
default equal to 2 bar. The low pressure alarm is suspended in
heating mode for a period of time equal to 3' (set_factory param-
eter (H parameter) from compressor switch on. It is permanently
suspended during cycle reverse
Every time the machine is powered, the control checks compres-
sor behaviour once via the yield control procedure (see 8.1); this
control is disabled from dip switch
This signal intervenes if the magnet circuit breaker switch protect-
ing the pump is opened. MTP (table 2, contact ID3, clamps M7.5
– M7.6, normally closed). This code is displayed only if the board
is used as a board spare part with SW up to version 3.6.
This signal occurs every time a partialisation takes place due to
the threshold mentioned in paragraph 8.5 being reached. The
machine blocks in alarm mode when the maximum number of par-
tialisation interventions allowed (expressed by the set_factory (5)
parameter: default 5) is exceeded. With inverter machine mode, it
also indicates a partialisation due to high compression ratio.
This signal occurs every time a low pressure partialisation takes
place, par. 8.5. The machine blocks in alarm mode when the maxi-
mum number of partialisations allowed (expressed by the set_fac-
tory (5) parameter: default 5) is exceeded.
This signal occurs every time a pressing line temperature par-
tialisation takes place (par. 8.5), the machine blocks in alarm
mode when the maximum number of partialisation interventions
(expressed by the set_factory (5) parameter: default 5) permitted
is exceeded.
Error in detection of the back emf. This error is returned by the
inverter control board and is linked to compressor peak problems
(longertek 4 code or longertek 20 code)
The inverter control board has internal communication problems
(longertek 5 code)
Excess current absorption by compressor (longertek 6 code)
The compressor does not absorb enough current, it may
turn in idle mode (longertek 7 code)
The inverter control board indicates incorrect bus voltage
(longertek 8 code)
The inverter control board indicates incorrect start-up of
the PMSM motor (longertek code 9)
Error on the IGBT (longertek 12 code)
Eeprom error on the inverter control board (longertek 13
code)
Code longertek 16
The inverter control board does not respond. It may not be
powered or the serial cable could be disconnected or the
A and B signals reversed
