6.6.1 Password
The button setting function can be protected by setting a password. This password is also valid for settings via Blue- tooth.
The default password is 0000. This password can only be changed using the button function.
6.6.2 Tariff
The default tariff is 1. The tariff can be set to T2, T3 and T4. Tariff 1 and 2 are always displayed in part 1 and 2 of the meters.
kWh values in tariff 3 and 4 will be added to the automatic scroll in part 2 of the display.
6.6.3 S0-Impulsausgang
The energy meter is equipped with two pulse outputs (forward & reverse or active & reactive) which are optically isolated from
the inside circuit. It generates pulses in proportion to the measured consumption for purpose of remote reading or accuracy testing.
The pulse output is a polarity dependent, open-collector transistor output requiring an external voltage source for correct
operation. For this external voltage source, the voltage (Ui) should be lower than 27V DC. The maximu m switching current (Imax)
is 100mA. To connect the impulse output, connect 5-27V DC to connector 4/6 (collector), and the signal wire (S) to connector 5
(emitter).

Appendix 3 - Modbus
A3.1 Communication via Modbus
The energy meter can communicate with the PC and other Modbus master devices. To read out the meter registers, first install
and configure the PC software. Use an RS485 to USB converter to connect the PC and the meter. The cable is connected to
terminals 7 and 8.
The following are the factory set Modbus parameters:
• Modbus addresse 001
• Baud rate 9600
• 8 data bits
• Even parity
• 1 stop bit
The baud rate can be changed to values 115200, 56700, 38400, 9600, 4800, 2400, 1200, 600 and 300.
The parity can be set to none or odd. Data and stopbit cannot be changed.
4PU: 4PS:
When connecting the meter through a serial converter (RS485) for testing, please be aware that because of not implementing the
complete Modbus infrastructure, there will be a need to put an additional resistor (120 ohms/ 0,25 watts) across the terminals
(7 & 8) on the meter side.
For the registers used in the meter and how to interpreted the data, please use the Modbus register map on the next pages.
