4-22 General Operation
1403-IN001A-US-P
Examples of Setpoint Operation
Setpoint Example 1 - Over kW Forward (+)
If it is desired that setpoint 1 energizes relay 1 when
kW exceeds +100kW for more than one second, and
de-energizes relay 1 when kW falls below +90kW for
more than two seconds, the following settings should
be used.
Setpoint Example 2 - Under kW Forward (+)
If it is desired that setpoint 1 energizes relay 1 when
kW is below +100kW for more than one second, and
de-energizes relay 1 when kW exceeds +150kW for
more than two seconds, the following settings should
be used.
Setpoint Example 3 - Over kW Reverse (-)
If it is desired that setpoint 1 energizes relay 1 when
kW exceeds -100kW for more than one second, and
de-energizes relay 1 when kW falls below -90kW for
more than two seconds, the following settings should
be used.
Setpoint Example 4 - Under kW Reverse (-)
If it is desired that setpoint 1 energizes relay 1 when
kW is below -100kW for more than one second, and
de-energizes relay 1 when kW exceeds -150kW for
more than two seconds, the following settings should
be used.
Relay Operation
The Powermonitor II has two output relays.
Operation of these relays is controlled by one of three
mechanisms.
•
Setpoint control - The relays can be independently
energized or de-energized based on the Setpoint
Configuration. Refer to Setpoints on page 4-16.
•
Pulsed output control - One of the relays can be
configured to provide a pulsed output based on the
measured value for kilowatt-hours or kilovar-
hours. Refer to Demand on page 4-9 for
additional information on this functionality.
•
Forced operation control - The output relay state
(energized or de-energized) can be forced via
either the Smart Communication Card or the
Display Module. The forced condition is
maintained until it is either removed by the user or
device power is cycled. Once the forced condition
is removed, the Powermonitor II relays revert to
normal operation.
