External recipe
out of range
the recipe number from the external controller is null or beyond the maximum
recipe number.
Component A is
not flowing
Possible cause
: after YF or YV1 and YG1/YG2 valves (when present)are
opened and the spray gun is open, no impulses are measured by the flowmeter.
Fault elimination
: you must trigger the gun into waiting time flow control until
the product is delivered. Extend the waiting time (DELAY ALARM NO FLOW -
DELAY ALARM NO FLOW PURGE/LOAD) in the machine’s parameters if
necessary (even if this increases the possibility of dosing error). If the product
does not flow despite the spray gun is open, the delivery system of the base
paint is faulty (no pressure product) or the valve of the corresponding product
does not open. If you receive an error message although the product flows within
the waiting time, the flowmeter on channel A is defected.
WARNING! The wrong dosage can reach the gun due to repeated error
messages and subsequent dispensed material. There is the possibility that only
one component flows.
This alarm can be automatically reset on a manual system installation, where the
paint is delivered through a manual spray gun, see parameter DELAY ALARM
NO FLOW
Component B (C)
is not flowing
same as above described, but for channel B.( C )
Leakage on valve
channel A
Possible cause
: the flow-meter of the paint base indicates that the product
flows, although the valve of the corresponding product is closed.
Fault elimination
: check valves of the product in the paint base channel. If the
system is equipped with Coriolis flowmeter, remove the air from the fluid; this
can be done by controlling the valve in manual mode. Counted impulses by the
flowmeters are shown in VALVE OPERATION page 2. If the problem persists,
you must contact your supplier
Leakage on valve
channel B ( C )
same as above described, but for channel B ( C )
Air supply
pressure too low
Possible cause
: lack of compressed air and / or air pressure to the valves of the
product is less than 5 bar
Fault elimination
. open the compressed air and / or increase the air pressure
on the pressure regulator in the control to a value higher than 5 bar. Check if the
pressure switch is defected.
POT life alarm
Possible cause
: the POT-LIFE is expired
Fault elimination
. Purge the equipment to reset the alarm.
Calibration factor
(A or B or C ) less
or equal to zero
Possible cause
: for the selected recipe, calibration factors are not yet defined.
Fault elimination
: you must login as user level 3 and enter the right values in
the calibration table; however the exact values must be obtained with a specific
calibration procedure, see on the manual at the relative section.
POT life pre-alarm
Possible cause
: the POT-LIFE time has reached 90%.
Fault elimination
: the mixed material in the houses need to be renewed as
soon as possible: spray it out, with a new load cycle or purge cycle
