output signal

Connecting the monitoring interface (depending on device)

The monitoring interface is only available on the following
devices:
• DEK 2.0, DEK 3.0, DEV 2.0.
• KEK 2.0, KEV 2.0.
• The monitoring interface checks the energy available in the energy storage.
• The external wiring (e.g. PLC input according to EN 61131-2) must provide the
switching signal (+24 V) with an earth reference via a high-ohm resistance
(1 kW - 100 kW).
• Typical fall times for 1 kΩ - 100 kΩ: Level below 5 V < 4 ms.

• The energy available is within the permissible range of tolerance to be ready for use.
• The Energy storage solution is ready to use.
