To prevent EMC problems, no wires are allowed to be connected to connection
terminals that are not used.
Separate connection terminals are available for the connection of the supply voltage for
the safety laser scanner and for the heater. This configuration makes it possible to
warm-up the safety laser scanner to operating temperature prior to actual operation.
An unregulated 24 V DC power supply is sufficient to supply the heating (max. ±5%
residual ripple). Full heating performance is only reached at a supply voltage of 24 V DC.
The heater’s cyclic current consumption is approx. 4 A.
If you use a common power supply for the safety laser scanner and the heater, you
must connect terminals 4 and 8, 12 and 16. In this case the power supply must comply
with the requirements for the safety laser scanner and provide the current required for
the safety laser scanner and the heater. (See Tab. 2 on page 12).
1) In an EFI system, a device must be defined as a guest using a jumper between pin 5 and pin 6. This is also
necessary if several safety laser scanners are connected to one EFI string on a Flexi Soft safety controller.
