DELAY ALARM NO
FLOW [s]
During the spraying process, the flow of the products is controlled. When the
measured flow is consistently less than the quantity assigned in MINIMUM
FLOW A, for channel A, or MINIMUM FLOW B for channel B, or MINIMUM
FLOW C for channel C an alarm is raised after the seconds here specified.
Default value 2 [s]
DELAY ALARM NO
FLOW PURGE/LOAD
[s]
During the loading/purging operation, the flow of the products is controlled.
When the measured flow is consistently less than the quantity assigned in
MINIMUM FLOW A, for channel A, or MINIMUM FLOW B for channel B, or
MINIMUM FLOW C for channel C,an alarm is raised after the seconds here
specified. This time can be longer than the time specified in DELAY ALARM
FLOW, to let the operator enter the painting booth and pull the gun’s trigger
after starting the cycles. Default value 10 [s
DELAY ALARM
LEAKAGE [s]
When the valves are closed, the absence of flow is checked. When a
consistent flow is measured from channel A or B, an alarm is raised after the
seconds here specified.
Default value 2 [s]
DELAY ALARM MIX
RATIO [ms]
When the mix ratio error is consistently greater than 1%, an alarm is raised
after the time here specified.
Default value 2000 [ms]
DELAY SIGNAL
FLOW OFF [s]
While spraying, after the gun’s trigger is released, color and hardener valves
are closed after the time here specified. Default value 3 [s]
DELAY
ATOMIZATION AIR
OFF [s]
While spraying, in case of alarm, color and hardener valves are closed.
Atomization air valve is closed too, with the delay here specified. Default
value 4 [s]
AUTOMATIC
MACHINE Yes/No
If the EcoDose 3K supplies an automatic machine, set this option as YES. In
this case automatic POT LIFE purge is allowed without checking signals from
gun-flushing box; a missing-flow alarm causes, after the delay time set in the
parameter DELAY ALARM NO FLOW, an immediate stop of spraying, closing
the valves .
Needle external
actuation Yes/No
Used when the
EcoDose 3K
supplies an automatic machine and is equipped
with a valve to control the guns’ needle. Choosing YES the needle valve is
opened also while spraying, controlled by the external signal commands
needle G1 or needle G2. If set to NO the needle is opened during the loading
and purging cycle, when YRF is closed.
