Function expansion using switching amplifiers
Using the UE402 switching amplifiers for C4000 and UE403 for M4000 the functionality of
the C4000 safety light curtains and the M4000 multiple light beam safety devices can be
expanded.
Example: Muting with M4000 and UE403
Two pairs of inductive muting sensors (1) connected to the UE403 detect the transport
platform. The UE403 switching amplifier (2) transmits signals via EFI (3) to the M4000
multiple light beam safety device (4) and controls the muting function.

Advantages:
•
less wiring due to local connection of all signals
•
less wiring between switching amplifier and ESPE due to EFI
