Pulse Input

PULSE MODE
KYZ MODE
PULSE
MODE
In pulse mode, either leading, or
trailing edge of the input pulse is
recognized as an event. In KYZ
mode, both leading and trailing
edges of the input pulse are
recognized as separate events.
Pulse Polarity NORMAL (N.O.),
INVERTING (N.C.)
NORMAL For the normal polarity, the open
to closed transition is considered
a pulse. For the inverting polarity,
the closed to open transition is
considered a pulse.
It has no meaning in KYZ mode
where both transitions are used.
Debounce
Time
1-100 ms
10 ms
The amount of time while the
state of the digital input should
not change to be recognized as a
new state. Too low debounce time
could produce multiple events on
the input change.
The debounce time is applied the same for all digital inputs. If you change
the debounce time for a digital input, the same debounce time is
automatically assigned to the others.
Configuring Relay Outputs
The PowerSmart+ PQM can be provided with two to four (depend on DI/O
module type) optional relay outputs. Each relay can be operated either
locally from the alarm/control setpoints in response to an event or by a
remote command sent through communications. It can also be linked to
an internal pulse source to produce energy pulses.
Using Power Software
Select General Setup from the Meter Setup menu, and then click on the
Relay Outputs tab.
