Appendix E
E.1 System Recovery Using Safe Mode
When power is first applied to the In-Sight 3400 sensor, the PWR LED will be red while the
sensor initializes. When initialization is complete, the LED will momentarily change from green to
orange during the LED start-up test, and then switch back to green. However, initialization failure
may be caused by corrupted job files, settings, or incorrect configurations. If the In-Sight 3400
sensor does not properly initialize—in other words, the PWR LED remains red and never
changes to green—the Safe Mode startup procedure may be used to re-initialize the In-Sight
3400 sensor.
To initialize the In-Sight 3400 sensor in Safe Mode:
1. Verify that the sensor is connected to a suitable power source, and that the In-Sight Control
Pad is properly connected.
2. Immediately after power is applied to the sensor, repeatedly press the VIEW button on the
Control Pad.
3. The initialization sequence will be interrupted by the following message:
Press the A4 button to enter SAFE mode, or press the A2 button to Cancel.
If the A2 button is pressed, the sensor will continue with the initialization, using the
previously configured settings, including the selected Startup job. If the sensor still fails
to initialize, the Startup job may be corrupted or incorrectly configured. Repeat this
procedure and select A4 to enter Safe Mode.
If the A4 button is pressed, the sensor will enter Safe Mode. In Safe Mode, the 3400
sensor settings will reset to their defaults. Before reconfiguring the sensor settings and
specifying any Startup job, cycle power to the sensor and verify normal initialization.
After a normal initialization, the In-Sight 3400 sensor may be re-configured and the
Startup job may be selected.
If the In-Sight 3400 sensor still does not initialize properly, or fails again after re-configuring the
sensor, login to the
