CH1/CH2 App
Rate Alarm
The application rate on channel 1
has deviated outside the user set
tolerance range for the user
specified tolerance time.
•
Check that the line speed reading is correct on the operating screen
•
Navigate to Ch1/2 Sensor configuration screen and check that linespeed is
configured correctly
•
If desired, ensure that the DC PID is in closed loop
•
Check that SPRAY WIDTH is entered correctly on the Ch1/2 config screen
•
Check that alarm tolerance time and window are set correctly on the Ch1/2
Alarm Settings page
CH1/ CH2 PWM
Alarm
The duty cycle on channel 1 has
started to drift towards the edg-
es of the nozzles' operable
bounds.
Contact your Spray Specialist
CH1/CH2 Level
Sensor Alarm
The channel 1/2 level sensor has
indicated a low level for a longer
amount of time than the user
specified tolerance time.
•
Ensure that the pump/liquid path to supply the tank with the level sensor is
open/plumbed correctly
•
Check that alarm tolerance time and window are set correctly on the Ch1/2
Alarm Settings page
System Integrity
(1
-
8) Fault
System integrity flowmeter (1
-
8),
when compared to theoretical
flow, is not reading an expected
value.
•
Navigate to the System Integrity screen and look for discrepancies between
the flowmeter readings
•
Ensure that these readings are reflected correctly on the physical flowme-
ters themselves if accessible
•
Clean the tip(s) of nozzle(s) attached to the alarming meter(s)
•
Check that alarm tolerance time and window are set correctly on the Sys-
tem Integrity page
CH1/CH2 Analog
LN SPD not
wired
There is no signal detected com-
ing from the channel 1/2 liquid
pressure sensor.
•
Check Monitor IO page for a non
-
error value ( > 3200 and < 65000)
•
Ensure that the sensor is configured correctly on the Ch1 sensor configura-
tion screen
•
Check sensor wiring
CH1/CH2 Atom-
izing Air Alarm
The liquid pressure on channel
1/2 has deviated outside the
user set tolerance range for the
user specified tolerance time.
•
Check system air supply pressure if gauge is present
•
Check manual valve orientation if present
•
Navigate to Ch1/2 Sensor configuration screen and check that the sensor is
configured correctly
•
Check pressure control signal (normally AO3/AO4) on the monitor I/O
screen for a non
-
zero (4000 or greater) value
•
Check that alarm tolerance time and window are set correctly on the Ch1/2
Alarm Settings page.
