Code
Description
Criteria
Remedy
H07
Spraying air flow too high
(Setting of spraying air on
the display)
The preset value for spraying air
is too high compared to the
transport air setting
Lower spraying air value or
increase value for transport
air to equalize air volumes
to the dense phase pump,
delete error code
H08
Transport air volume too
high (setting of powder
share on the display)
The preset value for transport air
is too high compared to the
spraying air setting
Lower transport air value
or increase value for
spraying air to equalize air
volumes to the dense
phase pump, delete error
code
H09
Powder output higher
than 100%
The powder output multiplied by
the powder hose length factor
and daily correction value is
greater than 100%
Daily correction value too large
Reduce powder output
Reduce daily correction
value
H10
Transport air range lower
deviation
The theoretical value for
transport air falls below minimum
Total air is smaller than minimum
Limit transport air to its
minimum value
High voltage:
H11
Gun error
No vibrations in the oscillator,
cable break, oscillator or gun is
defective
Contact a Gema service
center
H13
Gun Overload
Cable or cascade defective. The
control unit is switched off.
Contact a Gema service
center
Power supply:
H20
Voltage supply error
Mainboard
Mainboard defective
Contact a Gema service
center
H21
Supply undervoltage
Power pack defective or
overloaded
Contact a Gema service
center
H22
Wrong internal system
clock
Backup battery is empty
Contact a Gema service
center
EEPROM (equipment memory):
H24
EEPROM content invalid
EEPROM error
Contact a Gema service
center
H25
Timeout during EEPROM
writing
EEPROM error
Contact a Gema service
center
H26
Values not correctly
stored in EEPROM during
switching off
EEPROM error
Contact a Gema service
center
H27
EEPROM verification
erroneous
EEPROM error
Contact a Gema service
center
CAN bus:
H40
Permanent CAN bus error
The CAN controller changes into
BUS OFF condition.
No power supply or cable is not
connected.
Connect the cable,
otherwise contact Gema
service
