UnLt = UNLATCHED
Ltch = LATCHED
PLS.A = PULSE
PLS.C = KYZ pulse
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.
nor = NORMAL
(N.O.)
InS = INVERTING
(N.C.)
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.
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
Ac.Ei = kWh IMP
Ac.EE = kWh EXP
rE.Ei = kvarh IMP
rE.EE = kvarh EXP
rE.Et = kvarh TOT
AP.Et = kVAh TOT
Links a pulse relay to the internal energy pulse
source. The relay must be set into either pulse, or
KYZ mode.
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.
