Analog Input
Temperature B
(C) only with
Coriolis flowmeter
Possible cause
: wrong analog signal of temperature from PLC analog input
card
Fault elimination
: it requires maintenance intervention to check the electrical
connections
Temperature B
(C) out of range
only with Coriolis
flowmeter
Possible cause
: while spraying the temperature of the fluid component in
channel B ( C ) is beyond the assigned limits in parameters TEMPERATURE
ALARM THRESHOLDS
Fault elimination
: check the fluid condition and the electrical connections
Actual recipe zero
- Initialized to one
Possible cause
: at the power-up the actual recipe was zero. The actual recipe
is a retentive data and is not deleted switching off the machine.
Fault elimination
: if not at the first start up, verify all the other machine
parameters. Contact your supplier.
Flow out of range
Possible cause:
while working with closed loop flow control, the current flow run
out of tolerance
.
Fault elimination:
check the efficiency of the flow regulator and the gun’s hose.
Verify the parameters value of the closed loop regulator. If possible extend the
tolerance or the alarm delay in the regulation parameters
.
