In the Keypad Control Menu, you can choose the control place. You can enter the submenu level by

There are three different places (sources) where the Active Front End can be controlled from. For
each control place, a different symbol will appear on the alphanumeric display:
You can change the control place by entering the edit mode with Menu button right. The options can
then be browsed with the Browser buttons. Select the desired control place with the Enter button.
See the diagram on the next page. See also Chapter 6.3.3 above.
6.3.4
Active fault menu (M4)
You can enter the Active faults menu from the Main menu by pressing Menu button right
when the
location indication
M4
is visible on the first line of the keypad display.
When a fault brings the brake chopper to a stop, the location indication F1, the fault code, a short
description of the fault, and the fault type symbol (see Chapter 6.3.5) will appear on the display. In
addition, the indication FAULT or ALARM (see Figure 60 or Chapter 6.1.1) is displayed and, in case
of a FAULT, the red LED on the keypad starts to blink. If several faults occur simultaneously, the list
of active faults can be browsed with the Browser buttons.
The memory of active faults can store a maximum of 10 faults in the order of appearance. The
display can be cleared with the Reset button and the read-out will return to the same state it was in
before the fault trip. The fault remains active until it is cleared with the Reset button or with a reset
signal from the I/O terminal.

for 3 seconds when the Active
