External Laser Switching (Optional) - MICRO-EPSILON scanCONTROL 25 Series Operating Instructions Manual

Mounting and Installation

Connector multifunction
Function
- Laser on: Voltage between +laser on/off and -laser on/off 2.8 V... 31 V, I < 5 mA
- Laser off: Voltage between +laser on/off and -laser on/off < 0.8 V or open
Type 1
Fig. 20 Options to switch off the laser
If the voltages between pin 3 and pin 1 are < 0.8 V, the laser is off. No external resistor is necessary to the
current limitation. Connect pin 1 with 2 and pin 3 with 9 for permanent Laser on.
The external laser switching-off is implemented as a hardware solution and is a top priority. The laser can be
switched off, in addition, also by software.
