To operate the controller manually:
- Set the current limit selector as described in the Output Current Limits section.
- Set the power switch to ON.
The PWR device status LED indicates controller operation (green = controller operating).
Output Current Limits#
The current limit selector allows you to specify the output current to the light. The following graphic shows the available output current limits.
Adjusting the Light Intensity#
The current adjustment switch allows you to adjust the light intensity of the light.
To adjust the light intensity:
- Turn the current adjustment switch clockwise to increase the light intensity.
- Turn the current adjustment switch counterclockwise to decrease the light intensity.
The following table shows the output current in mA with the respective output current limit and light intensity set:
| Output Current Limit | 0 % Light Intensity | 25 % Light Intensity | 50 % Light Intensity | 75 % Light Intensity | 100 % Light Intensity |
|---|---|---|---|---|---|
| 1.25 A | 0 mA | 313 mA | 625 mA | 938 mA | 1250 mA |
| 0.9 A | 0 mA | 225 mA | 450 mA | 675 mA | 900 mA |
| 0.6 A | 0 mA | 150 mA | 300 mA | 450 mA | 600 mA |
| 0.3 A | 0 mA | 75 mA | 150 mA | 225 mA | 300 mA |
Operating the Controller Externally#
To operate the controller externally and turn the light on or off:
- Set the external trigger switch TRIG H/L to the desired mode, High or Low.
- Set the input signal of the external trigger as described in the Trigger Logic Switch Settings section.
- Set the power switch to ON.
The PWR device status LED indicates controller operation (green = controller operating).
External Trigger Switch Settings#
| Trig H/L | Input Signal | Light |
|---|---|---|
| High | High | On |
| High | Low | Off |
| Trig H/L | Input Signal | Light |
|---|---|---|
| Low | Low | On |
| Low | High | Off |
Troubleshooting#
Turning off the power switch for 3 seconds may help in cases of abnormal behavior or if one of the three protection modes has been activated, e. g., the overcurrent protection.
