13.1. Fault diagnostic

The ecom-EN2 is able to receive and to
process information provided via cable
transfer by the ecom-AK (read-out head
for digital firing automates).
Out of the main menu, select the sub-
menu "Fault diagnostic" and confirm
with <Enter>. The ecom-EN2 tries to
establish a connection with the ecom-
AK (display message: „Search in pro-
cess"). By successful attempt, the cur-
rent burner operation stand is displayed
as a graphic on the display. The opera-
tion stand can be recorded (max. 120
sec). Press <Enter> to initiate a new
recording (reset).
