5 Operating of the Fluid Inventory Control System HDA eco
The user is guided through the operation of the HDA eco by a menu structure (shown
in Annex A). The operating manual is orientated to this menu structure.
5.1 Switching on
After switching on the HDA eco, a function test runs (display test, program version
display, memory test, real-time clock test). If equipped with a WiFi socket modem and
if the WiFi interface has already been set up (see section 5.3.4.3.10), the HDA eco will
establish a connection with the existing network. The signal level and quality will then
be shown on the display for a few seconds.
The automatic dispenser is in the ‘Dispensing’ mode after switching on.
