Functions

Protective-field filter time

Brief clearing of the protective field (1 s or 2 s) is possible with-
out interruption of the gating event. Small gaps in the load can
thereby be tolerated.

Partial gating

■

The following SPG functions are available in all SPG operating modes:

• Gating termination by the control (see chapter 4.5.1 "Controlled gating end")

• Gating timeout extension (see chapter 4.5.2 "Gating timeout extension")

• Gating sequence reset (see chapter 4.5.3 "Gating sequence reset")

• Gating restart (see chapter 4.5.4 "Gating restart")

• Override (see chapter 4.5.5 "Override")

NOTICE

The following general functions of the MLC safety light curtains are available in all SPG operat-
ing modes (see chapter 5 "Functions"):

Start/restart interlock (RES)

Transmission channel changeover

Operating range selection

Signal output

Blanking
