FAULT CAUSE SOLUTION
TOL.
TIME
General/Gun output
error
This is normally caused by a short in a
nozzle cable or coil. This is the most
common fault.
Check all connecons and coils for
electric nozzles, or aached devices on
the nozzle output cables.
0s
Source current too high
The source current on PWM+ is higher
than 6A.
Check all connecons; look for shorts.
Use ammeter if required.
1s
Remote 4-20mA fault
The current on AI1 is lower than AI1
oset (4mA). There is a problem with
the sensor, or the wire is broken.
Check the connecons and wiring on AI1.
If not being used, set duty cycle opon to
“local”.
1s
Sink current too high
The sink current on PWM- is higher than
6A.
Check all connecons; distribute guns
over mulple 2008 modules.
1s
Internal temperature too
high
The temperature in the module is too
high.
Provide sucient cooling in the cabinet
where the module is located.
1s
High Voltage
The voltage on the +Vin input is higher
than 57V.
Use a suitable power supply, check
power supply (20 – 57 V)
1s
Low voltage
The voltage on the +Vin input is lower
than 20V.
Use a suitable power supply, check
power supply (20 – 57 V)
3s
Tank empty Tank level signals the tank is empty
Fill the tank, verify the level switch is
funconing, invert the switch.

DIAGNOSTICS
The diagnoscs screen is a tool to help with system troubleshoong. This screen groups together real-me readings
from connected digital and analog inputs and accessories and displays all of the read-only values in one locaon. These
values can help to diagnose the cause of any faults.
See Faults and Troubleshoong secon for more informaon.
