Main functions

This section describes main functions of Model KM1.

Function by unit

PMU1A (Electric power)
PMU2A (Power two-system) : Provides the power measurement function and 3-STATE
EMU8A (Pulse/temperature) : Has an event input and temperature input. It provides
CTD8E (CT expansion)

Output function

The following function is provided as an output function.
1) Total power consumption pulse output
PMU1A
(Electric power) (Power two-system)
When the total power consumption reaches the pulse output unit set by the user, pulses are
output from output terminal 1, output terminal 2, and output terminal 3 (terminal set by the
output terminal function setting).
The pulse ON time is normally fixed to 500 ms. The time for turning OFF the pulse is 100 ms
minimum. However, if it reaches the pulse output unit again within 600 ms after having reached
the pulse output unit, the pulse ON time becomes shorter, because higher priority is given to
the next output. After that, pulse of 100 ms is turned OFF, and then the next pulse is turned ON.
(The minimum pulse ON time is 100 ms.)
Pulse output is judged at sampling intervals.
