over-ridden using WinPM.Net software. If the alarm condition
is still true when the meter regains control power, the relay will
be re-energized.
• Latched
— Remotely Controlled: Energize the relay by issuing a
command from a remote
PC or programmable controller. The
relay remains energized until a command to de-energize is
issued from a remote
PC or programmable controller, or until
the meter loses control power. When control power is
restored, the relay will not be re-energized.
— Meter Controlled: When an alarm condition assigned to the
relay occurs, the relay is energized. The relay remains
energized—even after all alarm conditions assigned to the
relay have dropped out—until a command to de-energize is
issued from a remote PC or programmable controller, until the
high priority alarm log is cleared from the display, or until the
meter loses control power. When control power is restored,
the relay will not be re-energized if the alarm condition is not
TRUE.
• Timed
— Remotely Controlled: Energize the relay by issuing a
command from a remote PC or programmable controller. The
relay remains energized until the timer expires, or until the
meter loses control power. If a new command to energize the
relay is issued before the timer expires, the timer restarts. If
the meter loses control power, the relay will not be re-
energized when control power is restored and the timer will
reset to zero and begin timing again.
— Meter Controlled: When an alarm condition assigned to the
relay occurs, the relay is energized. The relay remains
energized for the duration of the timer. When the timer
expires, the relay will de-energize and remain de-energized. If
the relay is on and the meter loses control power, the relay will
not be re-energized when control power is restored and the
timer will reset to zero and begin timing again.
• End Of Power Demand Interval
This mode assigns the relay to operate as a synch pulse to
another device. The output operates in timed mode using the
timer setting and turns on at the end of a power demand interval.
It turns off when the timer expires.
