The data transfer codes L, B, C and T have been
reserved for the event data transfer between the
relay module and the control data communi-
cator.
The event register can be read by the L com-
mand only once. Should a fault occur, for ex-
ample, in the data transfer, it is possible, by us-
ing the B command, to re-read the contents of
the event register once already read by means of
the L command. When required, the B com-
mand can be repeated.
The setting values S1...S5 are the alerted set
values currently used by the protection relay
module. These values are set either by remote
control or by means of the setting knobs. The
values S11...S15 are set with the setting knobs
and the selector switches. Variables S21...S25
are set as percentage values via remote control.
The settings S21...S25 allow reading or writ-
ing. A condition for writing is that the pass-
word V160, for remote setting has been opened.
The variables S31...S35 contain the remote set-
ting values.
When the values of the variables S21...S24 are
to be changed, the variables can be given a per-
centage factor within the range 0...999. It is
possible to alter a setting value beyond the set-
ting ranges specified in the technical data of the
relay module. However, the validity of the set-
ting values are guaranteed only within the set-
ting ranges specified in the technical data.
Activation of the self-supervision function
(V165) prevents the relay module from operat-
ing as long as the self-supervision output is ac-
tivated and the IRF indicator is lit.
