11.8.6 Defining battery backup
In case of a power supply failure, the Conex
can be supplied with 24 VDC using an external
backup battery (UPS), for example Grundfos backup
battery, order no. 96725709 (336-308). A contact
from an integrated standby display on the battery
backup to an electrically isolated input on the
®
Conex
DIA-G indicates that the battery backup is
ready for operation.
The battery backup function is switched on in the
"Battery backup" submenu, and a setting defines
whether the integrated relay for the battery backup
has an N.C. or N.O. function:
•
Battery backup
– OFF.
– N.O. contact: Electrically isolated contact on
the UPS closes if the battery backup is faulty.
– N.C. contact: Electrically isolated contact on
the UPS opens if the battery backup is faulty.
