General information:
The device provides four different energy meter types:
| Energy total |
This energy meter is always counting. This energy meter cannot be reset. The following energy data is recorded:
|
| Energy resettable |
This energy meter is always counting. This energy meter can be reset. The following energy data is recorded:
|
| Tariff meter (1...4) |
If a tariff meter is selected/activated, counting is always performed on this meter. Tariff meters 1...4 can be reset. The following energy data is recorded:
|
| Process energy |
This energy meter counts the energies for a time controlled by the user. There is one register block for the current energy metering and one register block for the previous energy metering. The content of the current block is copied to the second block as soon as the new recording is activated. Once the recording has started, the runtime is counted up and displayed in a runtime register. Access and control of this meter type is only possible via the Modbus interface. The following energy data is recorded for each register block:
|
- The energy flows of the individual phases (divided into consumption / supply and inductive / capacitive) are also counted separately for the meter types “Energy total", “Energy resetable" and “Tarif meter“. Access to phase-specific values is only possible via Modbus or BACnet interface
- Internally, 64-bit counters are used that count Ws. This means that 5.124.095.576.030.431 Wh (= 5.124 TWh) can be counted. In the event of an overflow, the counters jump back to 0
- If large values appear in the counters, small changes can no longer be displayed
- There are no configuration options for the energy meters
| Impulse counter |
The impulse pulse counter counts the pulses registered at the digital input generated by an external device. The impulse counter can be reset. |
The device provides two different operating hour counters.
| Operating hours (T_tot) |
This counter keeps running as long as the device is supplied with voltage. |
| Load operation (T_load) | This counter is a load counter that starts running from a configurable power threshold (in W). The default seting for the powe threshold is 100 W. The value can be configured via the Modbus communication interface. |
- Resetting the meters/counters can be performed by means of the web server, the display or the communication interface (Modbus, BACnet, REST API)
