2.1.4.1 Meaning of the Indicators and Operator Controls:
On the front panel of the CP 142-2, there is a line of 8 LEDs. The upper three LEDs are the group
display. The meaning of the lower five LEDs depends on the status of the group display, as follows:
±
If no LED is lit in the group display, the lower five 5 LEDs indicate the status of the CP 142-2
(status display of the CP 142-2). The label to left of the LEDs then applies. The default display is
the status display.
±
If one or more of the LEDs in the group display are it, the lower five LEDs indicate the slaves
detected or active on the AS-Interface (slave display of the CP 142-2); the label to right of the
LEDs then applies.
You can toggle the display with the SET/DISPLAY button. The SET/DISPLAY button is also required
to configure the CP 142-2. If the button is not pressed for approximately 10 minutes, the CP 142-2
automatically switches to the status display.
