MESSAGE CAUSE ACTION
Too many dGS
output
More than one oAi has been
set as dGs (digital scroll)
Check the oAi parameters and set them
different from dGS.
Too many dGSt
output
One oAi has been set as
dGst (triac for digital scroll)
Check the oAi parameters and set them
different from dGSt.
Too many 6dG
output
More than one oAi has been
set as 6dG (blocked suction
valve for digital stream 6D)
Check the oAi parameters and set them
different from 6dG.
6dG, bEF or dGS
ConFig Error
oAi configured as 6dG before
the dGS
Check the oAi parameters and set 6dG after
dGS.
dGSt Output Error
One oAi has been set as
dGst (triac for digital scroll)
Check the oAi parameters and set them
different from dGSt.
dGSt not PrESEnt
One oAi has been set as dGs
(digital scroll)
Check the oAi parameters and set them
different from dGS.
dGS not PrESEnt
One oAi has been set as
dGst (triac for digital scroll)
but none relay has been set
as “dGS”
Check the oAi parameters and set them
different from dGSt if digital compressor is not
used.
Otherwise set 1 relay as dGS if digital
compressor is used
StEP ConFiG
Error
Load (step) configuration
error
A relay oA(i) has been set as compressor without
a previous relay oA(i-1) has been set as
compressor. EI oA1 = StP
no P3 ProbE
PrESEnt
The P3 probe is requested for
a function, but it’s not present
Check the parameters P3C
no LoAdS For
rEGuLAtion
None oA(i) is set as
compressors or fans
Check the setting of oA2, oA3, oA4, oA6
parameters
AOP2
P2 probe not available for the
4 – 20 mA output
P2 probe not available P2P = no. Enable the
probe setting: P2P =yES
The second probe P2 is used to control the
temperature of the engine of screw compressors.
Check CtyP and set it different from Scr.
no FAn ProbE
P2 probe not available for fan
regulation
P2 probe not available P2P = no. Enable the
probe setting: P2P = yES
The second probe P2 is used to control the
temperature of the engine of screw compressors.
Check CtyP and set it different from Scr.
too MAnY InC1
More than one oAi has been
set as inC1 (inverter for
suction 1)
Check the oAi parameters and set them different
from “inC1”.
No AnALoGuE
out For InC1
Non-analogue output has
been set as “inC1”
Check the oAi parameters and set them different
from “inC1”.
too MAnY InF
More than one oAi has been
set as inF (inverter for fan)
Check the oAi parameters and set only 1 as
“inF”.
No AnALoGuE
out For InF
Non-analogue output has
been set as “inF”
Check AoF and 2AoF and set one of them as
“inF”
CPr Circuit
conFiG Error
The kind of outputs are not
compatible with the 2 suction
circuits
Check parameters oA(i) , CtyP and set CtyP
different from Scr.
AO1 And AO2
SAME Function
AoF and 2AoF have the same
setting
Set AoF and 2AoF properly.
no Probe For SH
One relay is set as hot gas
injection valve (oA2 or oA3 or
oA4 = HGi), but the probe to
detected th superheat is
missed: ASH9 = nP
Set a probe to detect the superheat by the
parameter ASH9 = P3 or P4.
If the hot gas injection valve is not present, set
oA2 or oA3 or oA4 different from HGi.
