For PT primaries not found in the standard table use fine adjust.
To enter/exit Fine Adjust mode, press and together for two seconds.
Setup
Unf 410
Press the up key or down key to increase/decrease the PT setting in steps of 10V.
Press when the desired value is set to move to the next parameter.
3.1.5 Pulse Output Rate Programming
Setup
Plr 0.1 kWh
This sets the amount of energy measured between each pulse output. The scaling is dependant
on the display scaling and therefore on the CT and PT programming.
Press or to select pulse rates from a table.
Press when the desired value is set to move to the next parameter.
3.1.6 Pulse Output Length Programming
Setup
PlT 0.1
This sets the length, in seconds, of each pulse.
Press or to select pulse lengths (in seconds) from a table.
Press when the desired value is set to move to the next parameter.
3.1.7 Pulse Output Testing
Setup
Pto 9999
The pulse test facility allows the pulse output hardware and external system connections to be
commissioned without a measured load. The LCD shows Pto (off) and Ptr (run) and the number
of test pulses output. The test pulse rate is set automatically dependant on the programmed pulse
length (maximum 0.5Hz).
Press to start/stop the test pulses.
Press and together to stop the test pulses and simultaneously reset the test counter.
Press when the test is complete to move to the next parameter.
