44 M4M 20 NETWORK ANALYZER USER MANUAL
Digital Output
Each programmable I/O can be configured as Alarm output, Communication output, Pulse output, Output ON
or Output OFF.
Selecting Alarm output, the output can be associated to an alarm. Please note that it is mandatory to set up an
alarm prior to setting an output as Alarm output. In case no alarms have been set up, an information pop-up will
appear to inform that no alarm is set, with an hyperlink to the Alarm settings. For alarm settings, please refer to
chapter “8.4.Alarms”.
Selecting Comm. output, the output status is controlled directly via bus.
Selecting Pulse output, the output is set as a pulse generator associated with a measured parameter. It is
needed to consecutively set a measured parameter associated to the pulse output, the pulse ratio and the pulse
length.
Setting page Description
Parameter
Total Active Import Energy, Total Active Export Energy, Net Active
Energy, Total Reactive Import Energy, Total Reactive Export Energy,
Net Reactive Energy, Total Apparent Import Energy, Total Apparent
Export Energy, Net Apparent Energy.
Pulse ratio
Default values: 10/100/1000/5000 pulses for each kWh/kvarh/kVAh
or 10/50/100 pulses for each Wh/varh/VAh.
Manual between 1 and 999999 pulses for each kWh/kvarh/kVAh or
pulses for each MWh/Mvarh/MVAh.
Length Manual value between 10 and 990ms.
• M4M 20-M (MID) digital Output
The MID active energy import total function is assigned to pulse output 1.
The pulse duration is 30 ms and is not configurable.
The frequency is not configurable. It is adjusted by the algorithm according to the voltage and current
primaries, see follow:
CT*VT ≥ 1 000 000 1 impulse/MWh
100 000 ≤ CT*VT < 1 000 000 10 impulses/MWh
10 000 ≤ CT*VT < 100 000 100 impulses/MWh
1000 ≤ CT*VT < 10 000 1 impulses/MWh
100 ≤ CT*VT < 1000 10 impulses/kWh
10 ≤ CT*VT < 100 100 impulses/kWh
1 < CT*VT < 10 1000 impulses/kWh
CT*VT = 1 10 000 impulses/kWh
Selecting Output ON / Output OFF, the output acts as a contact close / contact open.
Selecting Output ON the circuit is closed, selecting Output OFF the circuit is open.
For output connections, please refer to chapter “5.4.Wiring diagrams”.
