Output Relay 1 (F1)
Trip

Setpoints > Outputs > Output Relays > Trip
NAME
Range: Up to 13 alphanumeric characters
Default: Trip
The setpoint is used to name the Trip relay by selecting up to 13 alphanumeric
characters.
SEAL-IN TIME (displayed only if Type=Pulsed)
Range: 0.00 to 9.99 s in steps of 0.01 s
Default: 0.10 s
This setting defines the time to be added to the Reset time of Relay 1 "Trip" output, thus
extending its pulse width. This is useful for those applications where the 52 contacts
reporting the breaker state are faster than the 52 contacts that are responsible for
interrupting the coil current.
BLOCK
Range: Disabled, Any FlexLogic operand
Default: Disabled
This setting defines a Block to the Trip output relay. When the selected input is asserted,
the Trip output relay is blocked.
TYPE
Range: Self-Reset, Latched, Pulsed
Default: Latched
This setting defines the sequence type of the Trip output relay. The functionality is
described in the Outputs > Output Relays > Trip and Close Relays section.
OPERATION
Range: Non-Failsafe, Failsafe
Default: Non-Failsafe
Failsafe operation causes the output relay to be energized when the Trip condition
signal is low and de-energized when the same signal is high. A failsafe relay also
changes state (if not already activated by an operand driving this output relay) when
control power is removed from the 869. 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 869 (if not already activated by a protection element).
The default value depends on the selection made in: Setpoints > System > Motor > Setup
> Switching Device Type. If the Switching Device Type is "Breaker", the Operation default
is "Non-Failsafe". If the Switching Device Type is "Contactor", the Operation default is
"Failsafe".
These defaults are applied in EnerVista when you are creating a set point file. If settings are
done using the relay HMI, the user must ensure that the "Operation" set point for the
breaker or contactor is as noted above.
A failsafe relay changes state when control power is removed from the relay. When the
Switching Device Type is "Contactor", an output relay in failsafe mode can result in
tripping off the motor when relay power is removed.
EVENTS
Range: Disabled, Enabled
