IQ DP-4000
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 1 5-minute demand window,
a new demand will compute every 1 5 minutes,
based on the energy used during the last 1 5
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 1 5-minute demand window,
the calculated demand is based upon the previous
1 5 minutes, but is updated every minute.
Set the power related demand by using
SW4 No. 2.
Place the switch in the:
•
OFF position for the sliding power demand window
•
ON position for the fixed power demand window
5.9.2 Power Demand Time Interval
Switch
SW4 Nos. 3, 4, and 5
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
Switch
SW4 Nos. 6, 7,
and
8
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.

5.1 0 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. Set Switch
SW5 No. 1
in the:
•
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 switch
SW5 No. 2
sets the energy resolution. The energy value
rolls-over to zeros when it exceeds 999999.
Set switch
SW5 No. 2
in the:
•
OFF position for KILO energy units
•
ON position for MEGA energy units
