Chapter 5 Configuring the EM13X Series General Meter Setup
88 EM13x Series SMART MULTIFUNCTION METER
The available relay outputs options are shown in Table 12.
Table 12: Relay Output Options
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.
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.
Links a pulse relay to the
internal energy pulse source.
The relay must be set into
either pulse, or KYZ mode.
