Always start with default gain. Other gains shall be used only if requested during
commissioning procedure by the ICT tool.
8.7.3.2 Connecting and setting voltage inputs
GUID-BE3E0554-3E96-4489-B8C9-E62953853BB7 v4
The RIM module of REX060 has two analog output channels that shall be connected to
two voltage input channels of the IED.
If both stator and rotor protection are used, there are two possible methods to perform
the connection.
1.
The recommended connection require four analog channels of the IED: two IED
voltage channels are used for the measured quantities for ROTIPHIZ; two more
IED voltage channels are used for the measured quantities for STTIPHIZ.

2. It is possible to use a mixed connection that requires only two IED voltage
channels for both ROTIPHIZ and STTIPHIZ. REX060 outputs are connected in
series. This connection is not recommended and can be used only in applications
where it is prove the possibility to use it. the use of this connection leads to
reduced performances of both ROTIPHIZ and STTIPHIZ.
