4.7.1
Pulse Rate
You can configure the number of pulses to relate to a defined
amount of Total Energy.
Please note there are limitations that need to be factored in
when setting the pulsed output. This is based upon the relay
output only being able to pulse 2 times per second.
For example, If the CT is set to 500/5A on a Single Phase
network this would generate (500Ax230V=115,000 / 1000)
115kWh which is 31W per second. A setting of 10IMP/kWh
(10 pulses per kWH) would generate 3 pulses per second.
This will exceed the 2 pulse per second limitation.
Pulse settings: 1 Pulse per: 10W (0.01) / 100W (0.1) /
1000W/1kWh (1) / 10kWh (10) / 100kWh (100) /1000kWh
(1000)
