# Flash operating mode

The Flash operating mode is used for flash operation. For example the light is switched on for every single scanned object.

## XLC4-1 (CP000411)

The following parameters can be adjusted:

| Parameter | Description | Min | Nominal | Max | Unit |
| --- | --- | --- | --- | --- | --- |
| Flash frequency |  | 1 | 10 | 20 | kHz |
| Trigger pulse |  | 10 | 20 |  | µs |
| ON-Delay | for input voltage 4.5 V |  | 10 |  | µs |
|  | for input voltage 10 V |  | 3 |  | µs |
| OFF-Delay | for input voltage 4.5 V |  | 20 |  | µs |
|  | for input voltage 10 V |  | 60 |  | µs |

## XLC4-1A (CP000411-1A) and XLC4-1F4 (CP000411-1F4)

The following parameters can be adjusted:

| Parameter | Description | Min | Nominal | Max | Unit |
| --- | --- | --- | --- | --- | --- |
| Flash frequency |  | 1 |  | 60 | kHz |
| Trigger pulse |  | 10 |  | tP – 2 | µs |
| ON-Delay |  |  | 0.6 |  | µs |
| OFF-Delay | for input voltage 4.5 V |  | 0.6 |  | µs |
