5.15.3.3 Load Shed Settings, Parameter Selection
The load shed feature activates the pulse initiator relay
when a user-selected parameter exceeds a
preprogrammed range (see 5.15.3.2 p.35). Select one
of the following parameters to monitor:
• Watts - Metered or Demand
• VA - Metered or Demand
• Metered Currents - I

5.15.3.4 Pulse Initiator Settings, Rate Selection
For this function, select the rate at which the relay
changes state as a value of energy to track with the
pulse initiator. For example, if you choose Watt-hours
as the parameter to track with the pulse initiator, the IQ
DP-4000 will change the state of the relay at every
specified interval of Watt-hours. If 50 Watt-hours per
Pulse is selected, the relay changes state every time 50
Watt-hours accumulate.
The energy per pulse corresponds to the energy (in
units), at the secondary winding of the PTs and CTs.
Therefore, you must consider the user-selected CT and
PT ratios when selecting the Energy per Pulse value.
See Table 5.AA for selecting the rate at which the pulse
initiator relay changes state.
Example: A system has the following configuration:
CT = 1400:5 PT = 240:120
The IQ DP-4000 is monitoring a constant power of
16,800 Watts.
Watt-hours is selected as the parameter for the pulse
initiator setting.
The CT ratio is 1400 / 5 = 280
The PT ratio is 240 / 120 = 2
The power at the secondary of the CTs and PTs is:
16,800 Watts / 280 x 2 =
16,800 Watts / 560 =
30 Watts (or 30 Watt-hours in 1 hour)
• If the energy per pulse is set to 1, each pulse will
equal 560 Watt-hours.
1400 x 240
x 1 = 560 Watt-hours per pulse.
5 120
• If the energy per pulse is set to 7, each pulse will
equal 3,920 Watt-hours.
1400 x 240
x 7 = 3920 Watt-hours per pulse.
