Label -----
This can be modified only through software. Use this
field to change the default label and assign a
descriptive name to this digital output.
Control Mode
External, Demand Sync,
Alarm, Energy
This field displays how the digital output functions.
• External: the digital output is controlled remotely
either through software or by a PLC using
commands sent through communications.
• Demand Sync: the digital output is associated
with one of the demand systems. The meter
sends a pulse to the digital output port at the end
of every demand interval.
• Alarm: the digital input is associated with the
alarm system. The meter sends a pulse to the
digital output port when the alarm is triggered.
• Energy: The digital output is associated with
energy pulsing. When this mode is selected, you
can select the energy parameter and the set the
pulse rate (pulses/kW).
Behavior Mode Normal, Timed, Coil Hold
• Normal: this applies when control mode is set to
External or Alarm. The digital output remains in
the ON state until an OFF command is sent by
the computer or PLC.
• Timed: the digital output remains ON for the
period defined by the On Time setup register.
• Coil Hold: this applies when control mode is set to
External or Alarm. For a unary alarm that is
associated with a digital output, you must set
Behavior Mode to Coil Hold. The output turns on
when the “energize” command is received and
turns off when the “coil hold release” command is
received. In the event of a control power loss, the
output remembers and returns to the state it was
in when control power was lost.
On Time (s) 0 to 9999 This defines the pulse width (ON time) in seconds.
