Plant switched off
and not purged
Possible cause
: the plant was switched off while it was not purged.
Fault elimination
: if the station was switched off with the red push button, press
the green button to switch it on again, reset the alarm, run a purge cycle if you
want to turn the plant off immediately after.
If the station was switched off cutting the main power, once powered again it
must be purged to reset the alarm.
External alarm
reserved - not used in this application
24V Power supply
off
Possible cause
: missing output power supply - Tripped overcurrent protection
on the 24V output circuits
Fault elimination
: it requires maintenance intervention in order to check the
electrical connections
Mix ratio out of
tolerance
Possible cause:
the error of the mixing ratio has exceeded 1.0%.
Fault elimination:
check the valves for leakage; if the system is equipped with
Coriolis flowmeter, make sure there are no air bubbles in the fluid circuits.
Gun 1 not in gun
flushing box
Possible cause
: In a system equipped with EcoCleaner M, a purge or load
cycle is started and the spray gun is not in the gun flushing box.
Fault elimination
: put the spray gun inside EcoCleaner M and restart the cycle.
The system can carry out the required cycle as long as the operator pulls
manually the spray gun’s trigger, within the time set for the alarm, see parameter
DELAY ALARM NO FLOW PURGE/LOAD
Gun 2 not in gun
flushing box
same as above described, but for gun 2
Analog input
temperature A
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 A
out of range only
with Coriolis
flowmeter
Possible cause
: while spraying the temperature of the fluid component in
channel A is beyond the limits assigned in parameters TEMPERATURE ALARM
THRESHOLDS
Fault elimination
: check the fluid condition and the electrical connectionsP
Analog Input
Density A only
with Coriolis
flowmeter
Possible cause
: wrong analog signal of density from PLC analog input card
Fault elimination
: it requires maintenance intervention to check the electrical
connections
Density A out of
range only with
Coriolis flowmeter
Possible cause
: while spraying the density of the fluid component in channel A
is beyond the limits assigned in parameters DENSITY ALARM THRESHOLDS
Fault elimination
: check the fluid condition and the electrical connectionsP
Analog Input
Density B (C)
only with Coriolis
flowmeter
Possible cause:
wrong analog signal of density from PLC analog input card
Fault elimination:
it requires maintenance intervention in order to check the
electrical connections
Density B (C) out
of range only with
Coriolis flowmeter
Possible cause
: while spraying the density of the fluid component in channel B (
C ) is beyond the limits assigned in parameters DENSITY ALARM
