Help codes
The error diagnosis codes (help codes) are shown in the display A5. The
error codes are stored in an error list in the order of their appearance.
Each error in the list must be individually acknowledged with the keys
T10 or T11.
The error codes are shown with the format Hnn, whereby nn is the nu-
meric code, if necessary with a leading zero.
The errors are displayed in the order of their appearance. The keys T10
and T11 cannot be used for other functions, as long as an error code is
shown on A5.
Here is the complete listing of all error codes possible for the OptiStar
CG06 Gun control unit:
Code Description Criteria Remedy
Pneumatics:
H01
FlowControl module error
FlowControl module defective,
check system parameter P0 and
set it to basis equipment without
FlowControl (P0=0)
H02
Conveying air control loop can-
not maintain preset value. Con-
veying air flow control does not
work correctly
Input pressure too low, throttle
defective
Check system parameter P0
and set it to basis equipment
without FlowControl (P0=0)
H03
Supplementary air control loop
cannot maintain preset value
Input pressure too low, throttle
defective
Check system parameter P0
and set it to basis equipment
without FlowControl (P0=0)
H04
Electrode rinsing air control loop
cannot maintain preset value
Input pressure too low, throttle
defective
Check system parameter P0
and set it to basis equipment
without FlowControl (P0=0)
H05
Shaping air control loop cannot
maintain preset value
Input pressure too low, throttle
defective
Check system parameter P0
and set it to basis equipment
without FlowControl (P0=0)
H06
Trigger valve (main solenoid
valve)
Solenoid coil current lower than
preset limiting value
Valve defective, main board or
cable defective
Main solenoid valve error, con-
nection cable from main sole-
noid valve to basic electronics is
missing, check main solenoid
valve
H07
Supplementary air volume too
high (total air setting on display)
The preset value for supplemen-
tary air is too high compared to
your conveying air setting
Reduce supplementary air value
or increase conveying air value
to balance air volume to injector
and clear help code
H08
Conveying air volume too high
(powder % setting on display)
The preset value for conveying
air is too high compared to your
supplementary air setting
Reduce conveying air value or
increase supplementary air val-
ue to balance air volume to in-
jector and clear help code
H09
Powder output higher than
100%
The powder output multiplied
with the powder hose length fac-
tor and the daily correction value
is larger than 100%
Daily correction value too large
Reduce powder output
Reduce daily correction value
H10
Conveying air range lower devi-
ation
The theoretical value for convey-
ing air falls below minimum
Total air is smaller than mini-
mum
Limit conveying air to conveying
air minimum
