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 connections and coils for
electric nozzles, or attached devices on
the nozzle output cables.
0s
Source current too high
The source current on PWM+ is higher
than 6A.
Check all connections; look for shorts.
Use ammeter if required.
1s
Remote 4
-
20mA fault
The current on AI1 is lower than AI1
offset (4mA). There is a problem with
the sensor, or the wire is broken.
Check the connections and wiring on AI1.
If not being used, set duty cycle option to
“
local
”.
1s
Sink current too high
The sink current on PWM
-
is higher than
6A.
Check all connections; distribute guns
over multiple 2008 modules.
1s
Internal temperature too
high
The temperature in the module is too
high.
Provide sufficient 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
functioning, invert the switch.

DIAGNOSTICS
The diagnostics screen is a tool to help with system troubleshooting. This screen groups together real
-
time readings
from connected digital and analog inputs and accessories and displays all of the read
-
only values in one location. These
values can help to diagnose the cause of any faults.
