Option 1 - use MainsPro relay
For any application shown above on the
Pict. 1
, or
Pict. 2
, or
Pict. 3
the concept of 2 independent units can
be used.
MainsPro sw version 1.4.1, hw version: 1.2 is independent ComAp protection relay which measures network
voltage and frequency and trips the supervised CB in case network values are not within adjusted limits.
In this concept, 2 independent units are used - controller and MainsPro unit. The primary breaker is
controlled directly from the controller; the secondary breaker (redundant) is controlled from the controller
through MainsPro unit.
Once controller detects network parameters out of limits, it trips the primary circuit breaker and
simultaneously gives a command to the MainsPro unit to trip the secondary circuit breaker.
Once the MainsPro relay detects network parameters out of limits, it trips the secondary circuit breaker and
simultaneously gives a signal to controller to trip the primary circuit breaker.
This interconnection ensures, that both breakers are tripped in every case the network parameters are out of
limits and also both the controller and MainsPro relay are tested every case the network parameters are out
of limits. In case any of the units fail, the alarm: GCB fail or MGCB fail occurs (In case MainsPro relay fail,
controller will detect redundant CB fail due to non receiving change on the redundant CB feedback. In case
controller fails to open the primary CB, it will detect the primary CB fail due to non receiving change on the
primary CB feedback signal)
Wiring instructions of this concept:
·
Signals for control of primary CB has to be configured to any physical binary outputs 1 – 8 of the
controller.
·
Signals for control of redundant CB has to be configured to any physical binary output 9-16 (9-12
based on the controller hardware) of the controller and connected to Tripping input of the MainsPro
unit – BI1 Ext Trip.
·
Signals for both primary and secondary CB feedback has to be configured to any binary input of the
controller.
·
Signal from MainsPro relay, signalizing that the CB shall be tripped has to be connected to the
Controller, LBI: Ext MP Trip.
·
All these signals are already prepared in default archives and there is no need to configure anything
in relation to this interconnection.
Controller and MainsPro relay have to be connected as follows:
