(approximately 8 minutes).

The front panel of the CP 243-2 has two rows of LEDs.

The LEDs CM, AUP, CER, APF, PWR and SF in the upper row represent the
status display. 
The B LED indicates B slaves. It is lit when the slave display is active if B
slaves are displayed.

The first five LEDs of the lower row indicate the connected slaves (slave
display). 
The other three LEDs indicate the slave group.

The meaning of the LEDs depends on the status of the group displays.

If all the LEDs of the group display are off, the status display is active; in other
words, the LEDs CM, AUP, CER, APF, PWR and SF indicate the status of the CP
243-2.

If at least one of the LEDs of the group display is lit, the status display goes off
(exception: “PWR” LED remains lit) and the slave display is active.

The SET button is required to configure the CP 243-2.
