Schneider Electric 4000 manual Timed, End Of Power Demand Interval, Absolute kWh Pulse, KVAh Pulse

Chapter 5—Input/Output Capabilities	63230-300-212
Relay Output Operating Modes	April 2001

•Timed

—Remotely Controlled: Energize the relay by issuing a

command from a remote PC or programmable controller. The relay remains energized until the timer expires, or until the circuit monitor loses control power. If a new command to energize the relay is issued before the timer expires, the timer restarts. If the circuit monitor loses control power, the relay will be re-energized when control power is restored and the timer will reset to zero and begin timing again.

—Circuit Monitor Controlled: When an alarm condition assigned to the relay occurs, the relay is energized. The relay remains energized for the duration of the timer. When the timer expires, the relay will de- energize and remain de-energized. If the relay is on and the circuit monitor loses control power, the relay will be re-energized when control power is restored and the timer will reset to zero and begin timing again.

•End Of Power Demand Interval

This mode assigns the relay to operate as a synch pulse to another device. The output operates in timed mode using the timer setting and turns on at the end of a power demand interval. It turns off when the timer expires. Because of it’s long life, this mode should be used with solid state relay outputs.

• Absolute kWh Pulse

This mode assigns the relay to operate as a pulse initiator with a user-defined number of kWh per pulse. In this mode, both forward and reverse real energy are treated as additive (as in a tie circuit breaker).

• Absolute kVARh Pulse

This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, both forward and reverse reactive energy are treated as additive (as in a tie circuit breaker).

• kVAh Pulse

This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVAh per pulse. Since kVA has no sign, the kVAh pulse has only one mode.

• kWh In Pulse

This mode assigns the relay to operate as a pulse initiator with a user-defined number of kWh per pulse. In this mode, only the kWh flowing into the load is considered.

• kVARh In Pulse

This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, only the kVARh flowing into the load is considered.

• kWh Out Pulse

This mode assigns the relay to operate as a pulse initiator with a user-defined number of kWh per pulse. In this mode, only the kWh flowing out of the load is considered.

• kVARh Out Pulse

This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, only the kVARh flowing out of the load is considered.
