Signaling via the Signal Outputs
There are three signal outputs on the unit that can be used to read off the specific
operating status. These signal outputs are preconfigured at the factory with the
following operating statuses:
•
Signal output "Bat. Alarm":
The contact is open when buffer operation is
not possible, or when battery replacement is recommended.
•
Signal output "Bat. Mode":
The contact is closed when the unit is in the
Battery mode.
•
Signal output "Bat. Charge":
The contact is closed when the battery is
being charged.
The preconfigured operating modes can also be customized as required, for
example, several events can be applied to one signal output.
The logics can be modified via the "759-870 V2" configuration software (starting
from Version 2.5).
