3-Phase Meter Telstar CT - Current Transformer Version

The smart-me Telstar CT is an MID-certified energy meter with integrated WiFi interface for the transmission of real-time data and with connection for external converters. The meter synchronises the measured values automatically and encrypted in the smart-me cloud. The measured data can be exported to various third-party systems and processed further via various interfaces.

Display

The counter has a rolling display. The items described below are displayed one after the other. After the last point, it starts again at point 1:

1.8.1 (A +) Active energy import tariff 1

1.8.2 (A +) Active energy import tariff 2

2.8.1 (A-) active energy delivery tariff 1

2.8.2 (A-) active energy delivery tariff 2

1.8.0: 5A (A +) active energy total import 5A basis

2.8.0: 5A (A-) active energy total delivery 5A basis

5.8.0 (Q1) Inductive reactive energy import total

6.8.0 (Q2) Total capacitive reactive energy import

7.8.0 (Q3) Total inductive reactive energy delivery

8.8.0 (Q4) Total capacitive reactive energy delivery

Wiring diagram

T1 button for installation

T2 special functions

In short: If T2 is pressed> 2s, the green LED lamp switches on / off. If this is activated, it shows the connection status

Glowing green: connected to smart-me cloud

Flashing green: connection is currently established, at the moment no connection

Long: If T2 is pressed> 8s, the display of the power is switched between active and reactive power. In addition, the calibration pulse LED alternates between active energy and reactive energy.

Very long: If T2 is pressed> 14s, the S0-0 pulse output is switched between active power and reactive power.

ATTENTION: This setting only changes the display, not in the smart-me cloud (app and website). If the reactive energy is to be displayed in the cloud, this must be done in the general settings.
