Inputs / outputs
When configuring your meter, the configuration interface may show all of the
possible ports, regardless of what is physically available on your meter.
NOTE: For applications where accuracy is important, use the digital output
located on the meter base.
1. Start ION Setup.
2. Open the Setup Assistant for your device.
3. Select Energy pulsing .
4. Select an energy pulsing source tab (such as Wh Del) to configure energy
pulsing using your meter’s digital output.
Digital output energy pulsing parameters available through ION Setup
Parameter Description
Kt The amount of energy source required to trigger the digital output. For
example, in the Wh Del tab, the Kt value would be amount of real energy
delivered (Wh Del) per pulse.
Pulse Width The minimum time in seconds between pulse transitions.
OutputMode Select the desired output mode:
• Pulse: the digital output sends a complete pulse when triggered.
• KYZ: the digital output makes a transition (off to on, or on to off) when
triggered.
Port Select an output port from the list. Only available output ports are shown
(ports that are not associated with another function).
(energy source)
ovrld Pulsing normally indicates that the output port should be operating
normally.
Pulsing suspended indicates that the output port is not able to pulse
quickly enough. Modify the Kt value to decrease the number of energy
pulses.
NOTE: To perform specialized configuration go into the advanced mode
of ION Setup and modify or add a new Calibration Pulser module. This is
an advanced procedure that should only be performed if you have
advanced knowledge of ION and the power system your meter is
connected to.
See the ION Reference , available from www.usa.siemens.com/pds, for
more information.
Calculate your maximum kWh/pulse (pulse weight) value
To calculate the kWh/pulse (pulse weight) value, divide the highest kW value you
can expect by the required pulse rate.
Make sure the required pulse rate does not exceed the maximum pulse rate for
the digital output.
NOTE: To convert from kWh/pulse to pulse/kWh you must invert (take the
reciprocal) of the value. For example, 1.8 kWh/pulse becomes 0.556 pulse/
kWh.
Example pulse weight calculation
For a maximum load of 1600 kW and a pulse rate of 2 pulses per second,
calculate the kWh/pulse value as follows:
1. Convert 1600 kW load into kWh/second:
(1600 kW)*(1hr) = 1600 kWh
(1600 kWh)/(3600 sec) = (X kWh)/(1sec)
X = 0.444 kWh/sec
2. Calculate the kWh required per pulse:
