Notifications
The analog interface features further outputs like OVP or CV
to notify the user of alarms or conditions (see table in „10.5.
These outputs are internally pulled to a voltage source via a high
resistor and can not drive a LED or lamp. They‘re intended for
current intake by switching an external relay or similar, which
can drive LED, lamps or other indicators. Alternatively, these
outputs can be connected to inputs of logic ICs.
