PuLS 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.

Ac.EE = kWh EXP
rE.Ei = kvarh IMP

rE.Et = kvarh TOT
AP.Et = kVAh
NONE Links a pulse relay to the
internal energy pulse
source. The relay must be
set into either pulse, or
KYZ mode.

Control Setpoints Setup
The PM172 provides 16 control setpoints with programmable operate and
release delays. Each setpoint evaluates a logical expression with up to four
arguments using OR/AND logic. Whenever an expression is evaluated as
“true”, the setpoint performs up to four concurrent actions that send a
command to the output relays, increment or decrement a counter, or trigger a
recorder. For more information on setpoints operation, see “Using Control
Setpoints” in Chapter 4.
This menu configures setpoints through the front display. To enter the menu,
select the “SEtP” entry from the Main menu, and press the ENTER button.
The menu uses three entries:
1. The upper window indicates a setpoint number.
2. The middle window selects a setup parameter to view or
change.
3. The lower window displays the parameter value.
