4.6.6 TERMINAL 12-13: EXTERNAL RESET – TYPE IB
With this function the total can be reset to zero with an external switch or passive signal. The Total
resets only when the switch opens. When a Normally Closed (NC) contact is used, the local clear
total function is disabled and a clear total is only possible with the external reset command.
The input must be switched with a potential free contact to terminal 12 for at least 200ms.

To connect an active signal to perform the reset function, please see Terminal 19-20: Isolated
reset input – Type IG.
4.6.7 TERMINAL 15-16: ISOLATED DIGITAL OUTPUT D3 – TYPE OG
An isolated scaled pulse output with a maximum frequency of 50Hz is available on digital output D3
on terminals 15-16. The output can switch voltages from 3 – 30Vdc with a maximum current of
60mA. The function of digital output D3 is determined by the settings of SETUP-menu 8: Pulse
Output (see chapter 3).
Output D3 can handle a maximum current of 60mA.
To limit the current, it may be necessary to include a resistor (R) in the circuit.
Size the resistor to limit the current to 60mA.
Fig. 32: Terminal connections – Isolated digital output D3
If a passive scaled pulse output with frequencies up to 500Hz is required, please see Terminal 03-
04 and 05-06: Digital outputs D1 and D2 – Type OT / Type OG
• Digital output D2 and digital output D3 are configured by the same settings of SETUP-
menu 8: Pulse output. Please make sure to program the settings in such a way that the
maximum output frequency is not exceeded (500Hz for D2 and 50Hz for D3).
• If digital output D3 is not used, please disable it in the settings to preserve battery power.
