3.2 Operating principle of the device
3.2.1 Principle of the device
The UE402 is an electronic module. It processes certain signals of the safety light curtain
C4000 or the cascading C4000 and merges them with the signals of other connected
systems. These systems may include:
an operating mode selector switch
a teach-in key-operated switch
a key-operated pushbutton for bypass
machine cycle contacts, e.g. for the top and bottom dead centres of a press
The UE402 is usually installed in the control cabinet.
3.3 Configurable functions
This chapter describes the functions of the safety light curtain C4000 which are selectable
via software, which can only be used in connection with switching amplifier UE402. The
functions can be partially combined with the other configurable functions of the safety light
curtain.
Test the protective device after any changes!
Each time the configuration is changed you must test the effectiveness of the entire pro-
tective device (see chapter titled “Test notes” in the operating instructions of the safety
light curtain C4000).
