Fault Corrective Action
1 Problem writing to Neuron
EEPROM
Turn off the power to the system to reset the
microprocessor.
If the problem persists, replace the gun driver card.
2 RAM test failure Turn off the power to the system to reset the
microprocessor.
If the problem persists, replace the gun driver card.
3 kV not within commanded gun
drive voltage
Check the gun current with no parts in front of the gun. If
the current is 105

A, check for a short circuit of the current
feedback wires in the gun cable:
Unplug the cable from the gun and trigger the gun.
S
If the error stays E3, replace the cable.
S
If the error changes to E7, check the resistance of the
multiplier as described in the gun manual.

Not used in this system Contact your Nordson representative for assistance.
5
6
7
Gun cable or multiplier open circuit If the current display is 1

A or less, check the multiplier
cable and electrode assembly for loose connections.
If the connections are secure, check the multiplier with a
ohmmeter as described in the gun manual.
If the multiplier reading is acceptable, check for a defective
cable as described in the gun manual.
8 Gun cable or multiplier short circuit Unplug the cable from the gun and trigger the gun.
S
If the error changes to E7, check the resistance of the
multiplier as described in the gun manual.
S
If the error code stays E8, check the continuity of the
cable as described in the gun manual.
9 Not used in this system Contact your Nordson representative for assistance.
10 Not used in this system Contact your Nordson representative for assistance.
11 Gun driver card hardware a. Turn off the power to the system.
b. Unplug the cable from the back of the gun.
c. Turn on the power to the system.
S
If the error code changes to 7 (open circuit), the
board is working correctly. Check the gun multiplier.
S
If the error code remains at 11, replace the gun
driver card.
12 System not communicating with
host interface
Check the network interface cable. Make sure that both
ends are securely connected and there is no damage to the
cable.
