Definition of terms
Observe new safety distance!
The safety distance between the sensor protection field
(FGS) and the danger point must be noted and, if necessary,
corrected.
Guest sensor only as point-of-operation guarding
In case of a FGS-Cascade with different resolutions (Host
sensor 14 mm, Guest sensor 30 mm) on LCU-P, the Guest
sensor cannot be used for point-of-operation guarding.
The "sensor test yes/no" function makes it possible, via
terminals 42 and 43 (cycle input) to test all connected sensors
by means of a normally closed contact. At the same time the
LCU deactivates the outputs.
In "with restart interlock" run mode the unit must be released
by actuating the reset switch; in "without restart interlock" run
mode the LCU automatically reactivates the outputs.
The "system test" function is always active. The actuation of a
contact on terminals 46 and 47 leads to a complete testing of
the unit, including sensors.
The type of test contact (make/break) can be set in the
programming menu. During testing the LCU deactivates the
outputs and issues the test command to the connected
sensors.
In the "with start/restart interlock" operating mode, the
necessary command device (Reset button n.o.) is activated, in
order to reach the green condition (activation of outputs).
