Switchgear - GE Multilin F650 Instruction Manual

5.8 RELAY CONFIGURATION
This menu is used for defining the SWITCHGEAR elements to be controlled by the relay. A switchgear element can be a
breaker, a line selector switch, a grounding selector switch, a busbar selector switch, etc. It is possible to define up to 16
switchgear elements. The setpoints are as follows:
• Select checkbox: enables or disables the control of a new switchgear element
• Contacts setpoint: allows selecting which type of contact is used for monitoring the status (open/closed) of the
element. The selection can be: 52a (contact type A, showing the same status as the represented element), 52b
(opposite status to the represented element), 52a+52b (both types of contacts are used), NONE (no status
monitoring).
• Opening Time setpoint: defines the maximum opening time of an element. It is used for issuing an opening time
failure signal if the element opening is not produced within this time.
• Closing Time setpoint: defines the maximum closing time of an element. It is used for issuing a closing time failure
signal if the element closing is not produced within this time.
• Contact A checkbox: allows selecting which operand or combination of operands activate the type A contact status.
Usually it will be an input contact wired to type A contact of the element (Breaker/selector switch). This column and the
next two columns are only active if the selected contact type in the Contacts column is 52a or 52a+52b.
• OR checkbox: selects a group of operands instead of a single one. The relay performs and OR of the signals, and its
output produces operation.
• NOT checkbox inverts the status of the signal selected in column Contact A.
• Contact B checkbox: allows selecting which operand or combination of operands activates the type B contact status.
Usually it will be an input contact wired to type B contact of the element (Breaker/selector switch). This column and the
5
next two columns are only active if the selected contact type in the Contacts column is 52b or 52a+52b.
• OR checkbox selects a group of operands instead of a single one. The relay performs and OR of the signals, and
its output produces operation.
• NOT checkbox inverts the status of the signal selected in column Contact B.
• Open text setpoint: allows associating a text to the control event associated to the element opening.
• Close text setpoint: allows associating a text to the control event associated to the element closing.
• Error 00 text setpoint: in case of using double contact for the switchgear element status (52a+52b), this setpoint
allows to associate a text to the Error00 internal status, this means, when both contacts are inactive during a period
longer than the associated to the opening or closing Operation, depending on which Operation is being performed.
• Error 11 text setpoint: in case of using double contact for the switchgear element status (52a+52b), this setpoint
allows to associate a text to the Error11 internal status, this means, when both contacts are active during a period
longer than the associated to the opening or closing Operation, depending on which Operation is being performed.
• ALARM setpoint: enables the issue of an alarm in the event of a close, open, 00-type, 11-type error. If it is configured
as an alarm.
• Opening init setpoint: this setpoint selects which operand or combination of operands indicate the initiation of an
opening operation, in order to allow the follow up of the operation and generate the corresponding alarms if the
operation is not successful. The operation bit signal used to launch the opening init must be configured in the
operations tab inside relay configuration.
• Closing init setpoint: this setpoint selects which operand or combination of operands indicate the initiation of a closing
operation, in order to allow the follow up of the operation and generate the corresponding alarms if the operation is not
successful. The operation bit signal used to launch the opening init must be configured in the operations tab inside
relay configuration.
