Setting Group Parameters of the Zone Interlocking
The zone interlocking Setting Group Parameters consists of three groups of setting to configure the zone interlocking
module to adapt to various application philosophies accordingly:
General: This group comprises the settings used to control the general usage of the zone interlocking module.
OUTPUT: What should be assigned to the Zone Out?
- Phase,
- Ground, or
- Both.
The OUTPUT group comprises the settings to configure the zone interlocking output logic. If the zone interlocking
application is used to a downstream device, the settings in OUTPUT group should be programmed accordingly. If
the zone interlocking application is only used for an upstream device (main breaker or Zone 1), the setting
ZoneInterlockOut within the OUTPUT group should be disabled.
TRIP: Activate the Zone Trip.
The TRIP group comprises the settings used to configure the zone interlocking TRIP logic. If the zone interlocking
application is applied to an upstream device, (main breaker or Zone 1), the settings in the TRIP group should be
programmed accordingly. If the zone interlocking application is only used for a downstream device (feeder breaker
or Zone 2), the setting ZoneInterlockTrip in TRIP group should be disabled.
Setting the above mentioned setting groups accordingly the zone interlocking module can be configured as:
Downstream device application (using only OUTPUT logic);,
Upstream device application (using only TRIP logic); or
Midstream device application (using both OUTPUT and TRIP logics together).
