ACF6
The total number of compressor of the 2 circuits ( CF04 + CF05 ) is:
> 6
> 4 with no direct compressor start-up (CO10
≠
0) or the number of steps
is
≠
0 (CF06),
> 2 and the intermittent valve is configurated with ON (CO08) and OFF
(CO09 )
≠
0
Pump-down function but at least in one circuit
The pump-down solenoid relay is not present
No pump-down pressure switch or evaporating probe when
the pump-down is enabled with unit in start
Or
No low pressure switch configurated.
The compressor configuration with CF04 and CF05 but not the relay
outputs:
Main
Intermittent valve when enabled with the ON / OFF time, CO08 / CO09
≠
0
When the by-pass time
≠
0 and there is no partialization or by-pass
valve configured
Motor part_2 / centre of the star with part-winding or star-delta
The necessary step valve configurated
One relay is configured
Too much compressors
Intermittent valve when ON / OFF time CO08 / CO09
≠
0
By-pass gas when the by-pass = 0
Compressor Motor coil 2 / center of the star with direct compressor
start-up
Wrong configuration of the capacity step valve
ACF7
Evaporator pump
√
Enabled (CO16
≠
0
) but the relay is not configured
√
Not enabled (CO16 =
0
) but the relay is configured
Condenser pump
√
Enabled (CO21
≠
0
) but the relay is not configured
√
Not enabled (CO21 = 0) but the relay is configured
Allarm configuration water pump in antifizee alarm
if Ar24=1 and Ar25=0
or
ifAr25=1 and not probe configurated like NTC
if Ar29=1 and Ar30=0
or
Ar29=1 and wrong confìguration of the probes
ACF8
Thermoregulation probe
The thermoregulation probe (in chiller with ST09, in heat pump when
enabled with ST10) is not properly configurated (it does not exist or it is
not a NTC)
Compressor rack is configurated with termoregulation like pressure
probe and not exist a pressure probe
