2 - 6 CIU 888
In redundant CIU configuration, one
of the CIUs goes to factory reset sta-
tus after configuration update.
CIUs site topology has dual masters
(2 systems issuing switchover com-
mand. Example: Entis Pro and Expe-
rion). During configuration update
multiple switchovers are initiated and
CIU goes to factory reset status.
If CIU went to this state then reset
both CIUs and perform set up redun-
dancy to recover back.
Ensure that site topology has only
one Master (one host system controls
CIU redundancy and issues switcho-
ver command) so that this issue
would not happen.
In redundant CIU configuration, when
tanks are deleted and configuration
update is performed CIU goes to dual
passive if the reload INI is not per-
formed in Entis Pro.
Entis Pro encounters communication
failures for tank record requests for
the deleted tanks and gives multiple
switchover commands to CIU which
result in a dual passive scenario.
1. Reload INI files in Entis Pro
2. Power off secondary CIU
3. Power on Secondary CIU. It takes
Secondary role and LCD also
shows that the Primary CIU is
scanning.
4. Power off Primary CIU
5. Secondary CIU becomes the
Primary and it starts scanning.
6. Power on Primary CIU. It takes
Secondary CIU role
