Technical Reference Manual
Relay parameterization
Local parameterization
The parameters of the relay can be set either locally via the HMI or externally via
serial communication with the Relay Setting Tool. When the parameters are set
locally, the setting parameters can be chosen via the hierarchical menu structure.
The desired language can be selected for parameter descriptions. Refer to the
Operator's Manual for further information.
External parameterization
The Relay Setting Tool is used for parameterizing the relay units. Adjusting the
parameter values using the Relay Setting Tool is done off-line, after which the
parameters can be downloaded to the relay via a communication port.
Design description
Input/output connections
All external circuits are connected to the terminals on the rear panel of the relay.
Terminals X2.1-_ are dimensioned for one 0.5...6.0 mm
wires and terminals X3.1-_ and X4.1-_ for one 0.2...2.5 mm
2
0.2...1.0 mm
wires.
The energizing phase currents of REF 610 are connected to terminals X2.1/1-2,
X2.1/3-4 and X2.1/5-6 (see table 4.2.1-1). The relay can also be used in single or
two-phase applications by leaving one or two energizing inputs unoccupied.
However, at least terminals X2.1/1-2 should be connected.
The energizing earth-fault current of REF 610 is connected to terminals X2.1/7-8
(see table 4.2.1-1).
The input terminals of the optional I/O module are located on connection socket
X3.1 (see tables 4.2.1-4 and 4.2.1-5).
Note!
REF 610 is provided with connection socket X3.1 only if the optional I/O module
has been installed.
Terminals X4.1/21-24 and X3.1/1-6 (optional) are digital input terminals (see table
4.2.1-5). The digital inputs can be used to generate a blocking signal, to unlatch
output contacts or for remote control of relay settings, for instance. The requested
functions are selected separately for each input in switchgroups SGB1...5. The
digital inputs can also be used to trigger the disturbance recorder; this function is
selected with SPA parameter V243.
The auxiliary voltage of the relay is connected to terminals X4.1/1-2 (see table
4.2.1-2). At dc supply, the positive lead is connected to terminal X4.1/1. The
permitted auxiliary voltage range of the relay is marked on the front panel of the
relay under the handle of the plug-in unit.
