4.2.4 Door interlock connection
At the rear panel of the device, a connector is provided for a door interlock contact to the device
(see Figure 22: Connections for remote door interlock contact and laser warning lamp).
The port must be a round screwed plug, type (x)V 40 according to IEC 60130-9, e.g. Lumberg
WSV 40 (as delivered).
(x): dependent on type, e.g. WS for an angled plug as delivered.
Door interlock contact 5V DC/20 mA
Relay contact laser emission (max. 24V/0.5A )
Figure 22: Connections for remote door interlock contact and laser warning lamp
Connecting the two connections remote door interlock contact and external door contact prevents
laser radiation from being emitted when the door of the laser room is opened.
This safety system shuts off the surgical beam automatically if the door is opened, thus
precluding any risk to the person entering.
The contact connector as delivered is factory-fitted with a jumper. To connect a door interlock
contact, remove this jumper and connect your door interlock contact to the same terminals. The
external contact must be potential-free and designed for at least 24V DC and 0.5A. If a door-
interlock contact is not used, ensure you keep the plug with the factory-fitted jumper connected.
Important information
The contact plug may only be connected with the device turned off and disconnected
from the power supply. Failure to observe this instruction can damage the device.
Never connect the contacts for the remote interlock and the foot switch to the mains,
because this will seriously damage the system. Connect these two connectors only in
the way described in this section.
Tip
If you have connected the door interlock contact with the entrance door, please check
every day before starting a treatment that the laser cannot be switched to the READY
mode with this door open. If there is a fault, inform the Engineering Department.
An external voltage source for a low-voltage warning lamp can be switched via two further
contacts on this connector. The internally installed switching relay is designed for a maximum
voltage of 24V AC and a maximum current of 1A. It is essential to observe the following safety
requirements for the connection of an external warning lamp:
WARNING
To avoid the risk of electric shock with consequential serious health problems and a fire
hazard with the transformer, if you use an external transformer to power the lamp,
please note:
A safety transformer complying with IEC/EN61558-2-6 must be selected.
