5.11. Operation with several sets of parameters
The units of the RE. 316*4 series permit up to four independent
sets of relay settings or protection configurations to be defined.
Only one of these sets of parameters can be active at any one
time when the protection is in operation. Provision is made for
switching between sets of parameters.
5.11.1. Switching sets of parameters
One of the four sets of parameters is selected by
a) applying a signal to a binary input (opto-couplers)
b) a signal from the station automation system (SCS).
Setting binary inputs
A maximum of four binary inputs are used for switching sets of
parameters. They are configured by selecting the menu item
“Edit inputs/outputs” in the “Edit system functions” menu.
If when configuring the inputs using the HMI they are left at their
default setting of “F” (FALSE = always OFF), the protection can
only operate with parameter set 1.
“Remote sel.” : If this I/P is activated, a signal from the sta-
tion control system (SCS) is necessary to
switch between sets of parameters, other-
wise the I/P's “ParSet2”, “ParSet3” and
“ParSet4” determine which set of parame-
ters is active.
“ParSet2”, “ParSet3” and “ParSet4”:
These three I/P's enable one of the four sets of
parameters to be selected.
ParSet2 ParSet3 ParSet4 Active set of para.
