The available relay outputs options are shown in Table 12.

UNLATCHED Unlatched mode: the relay goes into its
active state when the control setpoint is in
active (operated) state, and returns into
its non-active state when the setpoint is
released.
Latched mode: the relay goes into its
active state when the control setpoint goes
into active state and remains in the active
state until it is returned into its non-active
state by a remote command.
Pulse mode (normal pulse): the relay goes
into its active state for the specified time,
goes into non-active state for the specified
time and remains in the non-active state.
KYZ mode (transition pulse): the relay
generates transition pulses. The relay
changes its output state upon each
command and remains in this state until
the next command.
Polarity NORMAL (N.O.)
INVERTING (N.C.) NORMAL Normal polarity: the relay is normally de-
energized in its non-active state and is
energized in its active (operated) state.
Inverting polarity: the relay is normally
energized in its non-active state and is de-
energized in its active (operated) state. It
is called failsafe relay operation.
Pulse width 20-1000 ms 100 ms The actual pulse width is a multiple of the
1-cycle time rounded to the nearest bigger
value.
The pause time between pulses is equal to
the pulse width.

NONE Links a pulse relay to the internal energy
pulse source. The relay must be set into
either pulse, or KYZ mode.

kWh/Pulse Defines the pulse weight in kWh units per
pulse
Generating Energy Pulses through Relay Outputs
To generate energy pulses through a relay output:
1. Set a relay to either pulse, or KYZ mode, and then select a
polarity (active pulse edge) for energy pulses and a pulse width.
2. Select a source energy accumulator and the pulse rate for your
output.
3. Send your new setup to the meter.
