Remote Interlock Connector
The remote interlock connector is located at pin 1 and 2 of the molex connector on the Controller. The connector can
be short-circuited with an interlock jumper (included at delivery) for operation of the laser. To use the remote interlock
connector with an external switch, connect a pin 1 and 2 on a Molex plug. After the remote interlock connector has
been opened the laser will need to be reset by disconnecting from and then reconnecting to the power supply in order
to start again. Alternatively, it can be re-started using a special sequence of commands, see Section 7.4 for further
details. The signal level is between 0V and +5V with a pull up resistor, and the current required to ground the remote
interlock connector is 5 mA. The time delay in the hardware is <1ms, but after filtering by the firmware the reaction
time is extended to < 20ms.
Direct ON/OFF control
The Direct On/Off Control feature enables turning the laser ON/OFF using a 5-12 VDC signal. After having configured
the Controller for Direct Control operation (factory set or by executing @cobasdr 1), the laser can only start-up when
5-12V VDC (max 12.5 VDC) is applied to pin 3 on the analog connector with 0 VDC on pin 2 as reference. Shifting the
signal to 0 VDC on pin 3 will turn the laser off and put the laser in stand-by mode (status LED:s is POW and not
flashing).
This function is not available for CDRH compliant models.
NOTICE
This input only controls the on/off state of the laser and cannot be used to modulate the power
output. Integrated or externally mounted modulation solutions are available for most wavelength and
power combinations, see
for more information. a
