7.6.1 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.
7.6.2 Tari
The default tari is 1. The tari can be set to T2, T3 and T4. Tari 1 and 2 are always displayed in part 1 and 2 of the
meters. kWh values in tari 3 and 4 will be added to the automatic scroll in part 2 of the display.
7.6.3 S0 output
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 maximum
switching current (Imax) is 100mA. To connect the impulse output, connect 5-27V DC to connector xx/xx (collector),
and the signal wire (S) to connector xx/xx (emitter).
The default imp/kWh setting for the S0 output is 1.000. The S0 output setting can be modied to 10.000 / 2.000 /
100 / 10 / 1 / 0,1 / 0,01 imp/kWh.

7.6.4 Pulse type setting
The default pulse type setting is active & reactive. This means that the two pulse outputs pulse based on the active
and reactive energy. The pulse type can be set to forward & reverse, which means that the pulse outputs pulse based
on forward and reverse active energy.
7.6.5 S0 Pulse width
The default S0 pulse width is 30ms. The pulse width setting can be modied to 2-99ms (depending on the imp/kWh
setting).
7.6.6 Modbus ID
The Modbus ID can be set from 1 to 247, the default Modbus ID is 1.
