1 Application and Scope
C232-302-401/402/403/404-603 / C232/EN M/A23 1-1
1 Application and Scope
The C232 bay unit integrates control and protection (model 4 only) into one single
device (One-box solution).
The unit’s protection functions provide selective short-circuit protection in medium- and
high-voltage systems. The systems can be operated as impedance-grounded, resonant-
grounded, or isolated-neutral systems.
The control functions are designed for the control of up to six electrically operated
switchgear units equipped with electrical check-back signaling located in the bay of a
medium-voltage substation or a non-complex high-voltage station. External auxiliary
devices are largely obviated by the integration of binary inputs and power outputs that
are independent of auxiliary voltages, by the direct connection option for current and
voltage transformers, and by the comprehensive interlocking capability. This simplifies
the handling of switchbay protection and control technology from planning to
commissioning.
During operation, the user-friendly interface makes it easy to set the unit and allows safe
operation of the substation by preventing non-permissible switching operations.
The C232 has the following general functions:
Control functions
Control and monitoring of up to six switchgear units
Selection from over 200 pre-defined bay types
 Bay interlock
 Tap changer controller
Local control and display via user-selected panels on the LCD display:
 Bay Panel
 Measured Value Panel
 Signal Panel
Protection functions
Optional Three-pole measurement (A, B, C) + voltage or current measurement
Definite-time overcurrent protection, three stages, phase-selective (model 4 only)
Inverse-time overcurrent protection, single-stage, phase-selective (model 4 only)
Limit value monitoring
 Programmable Logic
 0..20 mA interface (option)
The user can select all general functions individually for inclusion in the device
configuration or cancel them as desired. By means of a straightforward configuration
procedure, the user can adapt the device flexibly to the scope of protection required in
each particular application. The unit’s powerful, freely configurable logic also makes it
possible to accommodate special applications.

C232-302-401/402/403/404-603 / C232/EN M/A23
Global functions
In addition to the features listed above, as well as comprehensive self-monitoring, the
following global functions are available in the C232:
Parameter subset selection (model 4 only)
Operating data recording (time-tagged signal logging)
Fault data acquisition (model 4 only)
Fault recording (time-tagged signal logging together with fault value recording of the
three phase currents, the residual current as well as the three phase-to-ground
voltages and the neutral-point displacement voltage)
Design
The C232 is housed in an aluminum case with threaded terminal ends in the form of
plug-in blocks and with reversible mounting brackets. The case is equally suitable for
surface mounting of flush panel mounting.
Inputs and outputs
The C232 has the following inputs and outputs:
Up to 4 current-measuring inputs (option)
Up to 14 output relays with freely configurable function assignment
Up to 20 optical coupler inputs for binary signals with freely configurable function
assignment for single signals
1 analog input, 0 to 20 mA (optional)
With the maximum number of binary inputs and outputs fitted, 6 switchgear units can be
monitored and 6 of these can be electrically controllable.
The nominal voltage range of the optical coupler inputs is 24 to 250 V DC without
internal switching. The auxiliary voltage input for the power supply is a wide-range
design. The nominal voltage ranges are 48 to 250 V DC and 100 to 230 V AC.
All output relays are suitable for both signals and commands. Nominal voltages and
currents of the measuring inputs has to be defined by using the appropriate order code.
The optional 0 to 20 mA input provides open-circuit and overload monitoring, zero
suppression defined by a setting, plus the option of linearizing the input variable via 20
adjustable interpolation points.
Interfaces
Local control and display:
Local control panel with LCD display (16 lines of 21 characters each with a resolution
of 128 x 128 pixels)
13 LED indicators, 8 of which allow freely configurable function assignment
PC interface
Communication interface(s) for connection to a substation control system or for
remote setting (optional)
Information is exchanged through the local control panel, the PC interface, or the
optional communication interfaces.
The communication interface (COMM1) is designed to conform either to international
standard IEC 60870-5-103 or to IEC 60870-5-101, MODBUS, or DNP 3.0. The C232
can be integrated into a substation control system through this communication interface.
