Following confi guration of the counters, the scheduled maintenance function is operational. Progress of the counters can be
viewed at any time in the Jb-VDI status menu.
When the counter expires, the signal will be shown on the alarm menu, and the unit may shut down (if the shutdown alarm
indicated by the closed padlock has been selected in the confi guration). Simply go to the Jb- VDI Status menu to reset the
counter and reset the signal. It is recommended to evaluate whether there are other checks that are nearing expiry, and carry
them out before resetting.

Note:
The dirty fi lter scheduled maintenance warning, confi gurable on Ae09, is disabled if VDI management is activated. This is becau-
se it is redundant with the checks required under VDI 6022.
The pGDE only shows the title of the counter, refer to the ID present on the screen and in the table shown here in the manual.
Important: the VDI 6022-1 function is provided to assist in managing the unit in accordance with the requirements of the
standard, as described above. The user is however always responsible for correct functioning of the equipment.
