Selecting test step 4 1. Select test step 4 in selection field 2 with the arrow keys and confirm your
selection by pressing the Service key .
After the test step is selected, the code for the current setting of the display
appears in selection field 1:
00 = LED display on the modules switched OFF

Switching LED display on/off 2. Select the desired code using the arrow keys of selection field 1 and con-

NOTE
i
The LEDs on the modules normally flash slowly (1 Hz) (for code 00). When
code 01 has been selected and confirmed, the CAN bus clock pulse of the
TTP protocol, which is output by the master module as a broadcast with a fre-
quency of 20 Hz, is output on the LEDs (the green life LED flashes on DX7).
Thus, by "wiggling through" all of the connectors, you can directly detect the
contact loss of the module on the CAN bus. The activation or deactivation of
this function simultaneously acts on all modules.
