8-1-3. Warning

8-1-3-1. Description

If an error is detected that prevents the F3SG-SR to continue normal operation, the SEQ indicator or
Area Beam Indicator (ABI) blinks to notify warning information according to the error. The F3SG-SR
continues normal operation. In the Auto Reset mode, the F3SG-SR automatically recovers from the
warning status when the cause of the error is solved. In the Manual Reset mode, the F3SG-SR keeps the
safety outputs in the OFF state. A reset signal is required to release the INTERLOCK state in this mode.

8-1-3-2. Troubleshooting

Identify an error according to the combination of the indicators when the error occurs. See the following
