SECTION 5 - PROGRAMMING THE IQ DP-4000

5.9.1 Power Demand, Fixed/Sliding

The IQ DP-4000 is programmed for the power related
demand to correspond to either a fixed or sliding
window.
•
Fixed Power Demand. With a fixed demand
window, the demand calculation is based on, and
updated at, the user-selected time interval. For
example, if you select a 15-minute demand window,
a new demand will compute every 15 minutes,
based on the energy used during the last 15
minutes.
•
Sliding Power Demand. For a sliding window, the
demand calculation is based on the user-selected
interval time, and is updated every minute. For
example, if you select a 15-minute demand window,
the calculated demand is based upon the previous
15 minutes, but is updated every minute.
Record the desired setting of Setpoint Switch S2.2 for
Rotary Switch position S3.4:
•
OFF position for the sliding power demand window
•
ON position for the fixed power demand window

5.9.2 Power Demand Time Interval

Setpoint Switches S2.(3 to 5) for Rotary Switch position
S3.4 determine the time interval, in minutes, that the
consumption sampling for the power related demand
calculations are based. Table 5.G shows the settings
for selecting the power demand interval.

5.9.3 Current Demand Time Interval

Setpoint Switches S2.(6 to 8) for Rotary Switch position
S3.4 determine the time interval, in minutes, that the
consumption sampling for the current related demand
calculations are based. Table 5.H shows the settings
for selecting the current demand time intervals.

5.10 ENERGY SETPOINTS

5.10.1 Reset Energy from Faceplate Setpoint

This setpoint enables or prevents you from resetting the
energy values (Watt-hours, Var-hours, and VA-hours)
from the faceplate. Record the desired setting of
Setpoint Switch S2.1 for Rotary Switch position S3.5:
(Set all 8 S2 switches).
•
OFF position to prevent resetting an energy value
from the faceplate
•
ON position to enable resetting at the faceplate. To
reset an energy value from the faceplate, you select
the parameter (Metered Watt-hours, Var-hours, or
VA-hours), and then hold down the Reset button
until the value is 0.
5.10.2 Energy Resolution
The IQ DP-4000 can be programmed to display energy
readings in KILO or MEGA energy units. A single Select
switch sets the energy resolution. The energy value
rolls-over to zeros when it exceeds 999999.
Record the desired setting of Setpoint switch S2.2 for
Rotary Switch position S3.5: (Set all 8 S2 switches).
•
OFF position for KILO energy units
•
ON position for MEGA energy units
