Troubleshooting
When a system error occurs an alarm notification will appear on the Controller display.
When head error occurs the error code will be displayed on the LED Head Information screen (refer to
Section 7.2,
“Error Codes”
).
When an error occurs, the current active exposure will be terminated immediately.
On any head level error condition, the alarm PLC output will be activated. The alarm output will clear when all
active alarms have been cleared, this may require a power reset to clear the error. If problems persist beyond
these troubleshooting points, please contact Excelitas Technologies Service Department (refer to
Section 12,
“Contact Information”
).
7.1
Symptoms and Possible Causes
Service to be completed by qualified Excelitas Technologies personnel only!
Always wear optical safety glasses while troubleshooting. Never put hands or
fingers in front of the lens. Serious personal injury may result.
Do not place any potentially combustible materials (e.g. paper, card, etc.) in front
of the LED Head. Risk of fire and damage to the UV LED Head may result.
If the controller fails to power up or function properly:
Make sure the AC power cord is securely connected to a grounded (earthed mains socket) functional 3-pin outlet.
Make sure the power supply cord is securely connected into the DC IN connector on the rear of the controller unit.
If the UV LED head fails to turn on
Unsure that the Door Lock Jumper is securely connected to the PLC Connector. If you are providing your own PLC
signals, ensure that Pins 24 and 25 are shorted together.
Unsure the UV LED heads are securely connected to the back of the unit. Warning: turn off unit before plugging and
unplugging the UV LED heads.
Unsure that the StepCure screen is filled in properly or left blank.
If you are using the start/stop button, ensure that the front panel has not been locked out from the PLC interface. If
the front panel is locked out, a lock symbol will appear on the status bar.
If the UV LED head gets a temperature fault
Ensure the ambient air temperature does not exceed 35C.
If you are using the 55mm length heads, ensure that the clamp assembly is securely fitted.
If the light intensity is too low:
Verify that the lens of the UV LED Head has been properly cleaned. Ensure Power is off.
Verify that the intensity level of the UV LED Head is set to correct level.
