These setpoints allow the choice of relay output operation to fail-safe or non-failsafe. Relay latchcode however, is defined individually for each protective element. Failsafe operation causes the output relay to be energized in its normal state and de-energized when activated by a protection element. A failsafe relay will also change state (if not already activated by a protection element) when control power is removed from the 369. Conversely a non-failsafe relay is de-energized in its normal non-activated state and will not change state when control power is removed from the 369 (if not already activated by a protection element). The choice of failsafe or non-failsafe operation is usually determined by the motor’s application. In situations where the process is more critical than the motor, non-failsafe operation is typically programmed. In situations where the motor is more critical than the process, failsafe operation is programmed.

SERIAL COMMUNICATION CONTROL

If enabled, the motor may be remotely started and stopped via Modbus® communications. Refer to the Modbus Protocol Reference Guide (available from the Modbus website at www.modbus.org) for details on sending commands (function code 5). When a Stop command is sent the Trip relay will activate for 1 second to complete the trip coil circuit for a breaker application or break the coil circuit for a contactor application. When a Start command is issued the relay assigned for starting control will activate for 1 second to complete the close coil circuit for a breaker application or complete the coil circuit for a contactor application. The Serial Communication Control functions may also be used to reset the relay and activate a waveform capture. Refer to the Modbus Protocol Reference Guide (available from the Modbus website at www.modbus.org) for more information.

The 369 is capable of controlling the transition of a reduced voltage starter from reduced to full voltage. That transition may be based on "Current Only", "Current and Timer", or "Current or Timer" (whichever comes first). When the 369 measures the transition of no motor current to some value of motor current, a 'Start' is assumed to be occurring (typically current will rise quickly to a value in excess of FLA, e.g. 3 × FLA). At this point, the REDUCED VOLTAGE START TIMER will be initialized with the programmed value in seconds.

369 Motor Management Relay

• If "Current Only" is selected, when the motor current falls below the programmed Transition Level, transition will be initiated by activating the assigned output relay for 1 second. If the timer expires before that transition is initiated, an Incomplete Sequence Trip will occur activating the assigned trip relay(s). • If "Current or Timer" is selected, when the motor current falls below the programmed Transition Level, transition will be initiated by activating the assigned output relay for 1 second. If the timer expires before that transition is initiated, the transition will be initiated regardless. • If "Current and Timer" is selected, when the motor current falls below the programmed Transition Level and the timer expires, transition will be initiated by activating the assigned output relay for 1 second. If the timer expires before current falls below the Transition Level, an Incomplete Sequence Trip will occur activating the assigned trip relay(s).
