Questions and answers concerning our LED lighting for Machine Vision


1. The illumination does not illuminate.

  • The green status LED does not light. Please check if the illumination is connected as described in the manual and that the correct operating voltage is set.
  • If you use a power supply with current limiting, please increase the allowable current.
  • The green status LED is on. Check if the illumination has been dimmed. Carefully turn the brightness potentiometer clockwise. If you have a version with an active VC-brightness regulation, please check if the circuit of the VC-voltage input is ok. Also check if the control voltage has at least 1 V. With Flash illuminations check that the necessary trigger signals are present. The status LED should briefly light up red when a trigger is released.

2. Switching the brightness regulation from potentiometer operation to VC-operation

  • Most LED illuminations with an integrated controller have two settings for the LED brightness - either by using an integrated potentiometer or over the VC analog input. Usually the devices are set according to your wishes. In case you want to change the settings though, please remove the diffusing plate (with ring and square illuminations). Depending on the illumination model, there are two small slide switches on the control panel. Operate the white/red switch.
  • We recommend to return Spot Lights, Coaxial, Dome and Dark Field Lights with an integrated controller to us. We will perform the necessary settings for you.
  • Devices with an external controller as well as new lightings (e.g. LB-Serie, Spot10W...) can be operated with both settings without having to switch. In that case, please read the manual.

3. Switching the trigger mode SPS – TTL

  • Our flash lights with an integrated controller have two trigger modes - SPS-trigger (15 V and more) and the TTL-trigger (3 V and more). Usually the devices are set according to your wishes. In case you want to change the settings though, please remove the diffusing plate (with ring and square illuminations). Depending on the light model, there are two small sliding switches on the control panel. Operate the blue/red switch.
  • We recommend to return Spot Lights, Coaxial, Dome and Dark Field Lights with an integrated controller to us. We will perform the necessary settings for you.
  • Devices with an external controller can be operated with both trigger settings without having to switch. In that case, please read the manual.
