PULSE

KYZ pulse

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.

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.

Configuring Analog Outputs

The meter can be ordered with two optional analog outputs with options
for 0-1mA, ±1mA, 0-20mA and 4-20mA current outputs.
