Criteria
Controller
Action
Solution
H17
Arc detection
both limits
A grounded object came too
close to the applicator at too
high of a speed.
Stop
H18
Arc detection
unspecified
Arc detection triggered due to
unspecified reason
Stop
H19
Arc detection
drive voltage
Power supply drive voltage
rose too quickly.
Stop
• Verify closest distances to parts.
• Verify fastest approach to parts.
• Verify paint conductivity.
• Verify spraying parameters
associated with arc detection, see
Run Screen 2 (Arc Limits), page 52
H91
Power Supply
Communication
Error
Communication between
controller and power supply
failed
Stop
• Verify applicator power
cable connection, perform
Power Cable Continuity, page 64
, and
replace cable if needed.
• Replace applicator power cable or
applicator power supply if needed.

H20
Controller
mainboard
voltage
tolerance
Onboard generated voltage is
out of tolerance
None
H21
Controller
mainboard
voltage failure
24V supply drops below 21V.
Remark: No error code is
displayed, only logged.
Shutdown
• Verify all connections inside of
controller are properly made.
• Verify power source is good.
• Replace 24 VDC board or power
board if necessary.
H24
Memory
contents invalid
Magic number doesn't match
expected value
Initialize
defaults
H25
Memory write
timeout
Writing to EEPROM takes
longer than 10ms
None
• Verify all connections inside of
controller are properly made.
• Replace main board if necessary.
H26
Memory
shutdown error
Data to be written at power off
hasn't been properly saved to
the EEPROM
None
• Do not turn off controller so quickly
after making setting changes.
• Verify all connections inside of
controller are properly made.
• Replace main board if necessary.
H27
Memory verify
failure
Verification of the data written
to the EEPROM failed
None
• Verify all connections inside of
controller are properly made.
• Replace main board if necessary.
H80
Safety controller
communication
Error
No response/timeout to
a request. Error report
on command execution.
Response data mismatch
Stop
H81
Safety controller
self-test failure
The self-test performed by the
safety controller detected an
error
Stop
• Verify all connections inside of
controller are properly made.
• Clear error. If it returns, call for help.
• Replace main board if necessary.
H82
Safety controller
not alive
Heartbeat message timeout
Stop
• Verify all connections inside of
controller are properly made.
• Replace main board if necessary.
H83
24 VDC interlock
missing
24 VDC interlock removed
while electrostatics in operation
Stop
• Verify DIO cable connections.
• Verify connected interlocked devices
are functioning.
• Verify all connections inside of
controller are properly made.
• Replace main board if necessary.
