5.13 POWERNET PROGRAMMABLE SETPOINT
You can allow programming of the IQ DP-4000 using
PowerNet / IMPACC with this setpoint. You must enable
this setpoint in order to download information to the IQ
DP-4000 from Cutler Hammer's PowerNet software.
Record the desired setting of Switch
S2.7
for Rotary
Select Switch position
S3.C
as follows:
(You must set
all 8 S2 switches; otherwise, communication mode
and alarm thresholds will be overwritten)
•
OFF position to disable programming of the DP-4000
via PowerNet / IMPACC
•
ON position to enable programming of the DP-4000
via PowerNet / IMPACC
If disabled, the DP-4000 will continue to communicate
over PowerNet / IMPACC, although you cannot change
the setpoints remotely.
5.14 DP-4000 / DP-2 MODE SETPOINT
This setpoint allows the DP-4000 to communicate over
PowerNet / IMPACC either as a DP-4000 or as a Data
Plus II (DP2). This setpoint affects communications only.
It does not affect the operation of the unit. This allows
DP-4000 compatibility with older, existing systems.
Record the desired setting of Switch
S2.8
for Rotary
Select Switch position
S3.C
as follows:
(You must set
all 8 S2 switches)
•
OFF position to communicate as a Data Plus II
•
ON position to communicate as a DP-4000
5.15 OPTIONAL I/O SETPOINTS
These setpoints are relevant only if the IQ DP-4000 is
equipped with the optional I/O module.
5.15.1 Discrete Input Setup Setpoint
Note:
This setpoint is relevant only if the IQ DP-4000 is
equipped with the optional I/O module.
The discrete input is configured to either a sync or a
reset input. Record the desired setting of Switch
S2.7
for
Rotary Select Switch position
S3.5
as follows:
(You
must set all 8 S2 switches)
•
OFF position to function as a sync pulse
•
ON position to have the discrete input function as a
reset input
If the discrete input is set up as a sync pulse input, a dry
contact closure across the terminal blocks of the discrete
input will cause the start of a new demand window. The
sync window time can be variable or fixed, determined
by setting the sync pulse setpoint (see 5.15.3 p.34).
If the discrete input is set up as a reset input, a dry
contact closure across the terminal blocks of the discrete
input will attempt to reset an active alarm. (This is
identical to using the Reset pushbutton when resetting
an alarm.)
5.15.2 Sync Pulse Setpoint
Note:
This setpoint is relevant only if the IQ DP-4000 is
equipped with the optional I/O module.
The IQ DP-4000 is designed to calculate the demand
either by an internal synchronizing timer or by an
external signal.
Record the desired setting of Setpoint Switch
S2.8
for
Rotary Select Switch position
S3.5
as follows:
•
OFF to calculate demand based on an external
signal (see Section 5.15.1 p.34 - Discrete Input
Setup)
•
ON to calculate demand based on a pre-
programmed time(see Section 5.9 p.24 - Demand
Parameters)
5.15.3 Pulse Initiator/Load Shed Setpoint
The IQ DP-4000 has a relay which can be programmed
based on the amount of power and energy measured.
The pulse initiator function tracks the amount of energy
measured and the load shed function changes the state
of a relay when a predetermined power threshold is
exceeded.
Record the desired setting of Setpoint Switch
S2.1
for
Rotary Select Switch position
S3.D
as follows:
•
OFF to use relay for the pulse initiator function
(see paragraph 5.15.3.1, p.34)
•
ON to use relay for the load shed function
(see paragraph 5.15.3.4, p.38)
5.15.3.1 Pulse Initiator Settings, Parameter Selection
The pulse initiator changes the state of the pulse initiator
relay at a rate proportional to the amount of energy the
IQ DP-4000 measures, based on a user-selected energy
parameter and pulse rate. Select one of the following
parameters to track with the pulse initiator:
•
Watt-hours (positive or negative)
•
Var-hours (positive or negative)
•
VA-hours
See Table 5.X for selecting the energy parameter.
= OFF
= ON
