Chapter 8 Configuration
Start the teach-in process as follows:
Table 11 - Starting the teach­in process
The SC300 now teaches-in the current configuration and shape of the protective field.
The process takes approx. 15 seconds. During the teach-in the flashing diagnostics LEDs
indicate the configuration detected:
Table 12 - Meaning of the diagnostics LEDs during teach-in
Using the LEDs, check whether the teach-in was successful:
Table 13 - LED displays after teach-in
After teach-in it is imperative you check the protective field (see “Tests of the protective
device by a specialist or authorized personnel” on page 38).
If the teach-in fails:
Check and rectify as necessary the following causes:
– Is the reflector fitted and clean?
– Is the reflector perpendicular to the area of the protective field?
– Is the reflective tape or are sub-segments of the tape very short?
Using the internal teach-in key Using the key-operated pushbutton for teach-in
Actuate the internal teach-in key using the teach-in pin as
follows:
Actuate for approx. 5 s
(the diagnostics LED 4 flashes 5 times).
If the SC300 does not react, the internal teach-in key is
probably locked. Start the teach-in process using the
key-operated pushbutton for teach-in or unlock the
teach-in key (see “Locking the internal teach-in key” on
page 43).
Release for approx. 2 seconds
(the diagnostics LED 4 flashes 2 times).
Actuate for approx. 5 s
(the diagnostics LED 4 flashes 5 times).
Important: Now remove your hand from the
protective field so that the SC300 can completely detect
the protective field.
Press the external key-operated pushbutton for teach-
in for at least 0.5 seconds.
The diagnostics LED 4
G illuminates.
