1Preface
The SELCO C6200 module provides integrated frequency stabilization, voltage stabilization,
check/automatic synchronisation, active/reactive load sharing, integrated protection, basic and
programmable I/O and data acquisition. Finally, the C6200 module can operate with other C6200
modules and interface with the SIGMA S6500 User Interface Module via the CAN bus or SCADA
designed power management system via MOD bus.

3Installation
The C6200 module is secured to the rear of the switch board using four 5 mm. screws. DIN rail
mounting is not advisable due to the weight of the module.
Please ensure that enough space is given around the module so that the plug-in terminals can be
removed and reinserted. The length of the cables should also allow for the easy removal and
insertion of the plug-in terminals.

4Isolation and Grounding
In marine installations ground and common reference (COM) should not be connected together. In
a ship installation the hull is the “ground”. Connecting any of the COM connections on the C6200
module to ground (hull) or switchboard chassis may cause instability within the system.
As a general rule:
1. COM terminals should not be connected to ground (hull) or switchboard chassis.
2. Negative poles of the power supplies should not be connected to ground (hull) or
switchboard chassis.

5Connection
The C6200 module is connected using plug-in terminals. The plug-in terminals provide safe and
durable connection without sacrificing ease of installation and servicing.
5.1 Power Supply
The electronics of the C6200 module are powered by one power supply. The supply operates on a
nominal voltage of +24 V DC and the supply will tolerate wide variations in the supply voltage.
The aux supply occupies terminal 29 and 31 of the AUX SUPPLY plug-in connectors.
Terminal Description Signal Connection
29 AUX SUPPLY + +24 V DC Positive terminal of primary supply
30 FREE FREE
31 AUX SUPPLY - -24 V DC Negative terminal of primary supply
The auxiliary power supply is not isolated from the remaining electronics of the module with the
exception of the GOV and AVR controller. This means that the supply reference terminal (terminal
31) has connection to the module’s COM terminal.
The front AUX SUPPLY LED illuminates with a steady green light to indicate that the supply
voltage is OK and within the limits of safe operation.
5.2 Voltage Inputs
The AC voltages connect to the BUS BAR VOLTAGE & GENERATOR VOLTAGE INPUTS
plug-in terminals.
The voltage inputs can operate with high voltage (up to 690 VAC nominal), so precaution
must be taken to avoid electrical shock and personal injury. Do not touch the VOLTAGE
INPUTS plug-in terminal unless you are absolutely sure that power source is off (e.g. the
generator is stopped and blocked against starting).
Voltages above 690 VAC are supported through use of external transformers (PT). When using PT
it is important to ensure that the PT does not affect the phase of the voltage measurement. Phase
shift in the PT will directly affect the calculation of the power factor, and thereby the calculation of
active and reactive current/load.

The phases L1 & L2 of the bus bar and generator source should be connected to L1 & L2 of the bus
bar/generator VOLTAGE INPUTS plug-in terminals. Intermediate 2 A slow-blow fuses should be
inserted between the individual phases and the related voltage inputs. It is very important that the
phases are connected in the correct order. Interchanging the phases will result in an incorrect power
factor calculation and thereby incorrect calculation of active/reactive current/load. It is very
important that the phases are connected to the corresponding terminals (phase 1 to L1, phase 2 to
L2 ).
Terminal Description Signal Connection
5 VOLTAGE INPUTS L1 AC voltage Generator phase L1
6 VOLTAGE INPUTS L2 AC voltage Generator phase L2
The GENERATOR VOLTAGE LED shows whether or not the voltage levels measured between
the phases are within limits. The reference is the nominal phase-phase voltage (NOMVOLT). The
voltage levels are compared to the limits defined by the voltage OK window (VOLTOKWND) of
the configuration.

2 VOLTAGE INPUTS L2 AC voltage Bus bar phase L2

5.3 Current Inputs
The C6200 module measures current through an external current transformer (CT). The C6200
module is available in two different variants; one is for 5 A CTs and one for 1 A CTs. Please ensure
that you have the correct variant of the module before proceeding with the installation.
The CT ratio should cover maximum current of the generator.
The CT must also be capable of coping with short-circuit currents over short periods.
The external CT is connected to the CT INPUTS plug-in terminal. It is important to ensure that the
direction of the current flow is correct. The current flow is indicated by the S1 and S2 notation on
the CT. S1 of the CT connects to terminal 14 and S2 of the CT connects to terminal 13.
Terminal Description Signal Connection
13 CT INPUTS 5 AC current S2 of the CT on phase L3
14 CT INPUTS 6 AC current S1 of the CT on phase L3
Make sure that the secondary side of the CT is shorted (make a connection between S1 and
S2) before disconnection of the CT INPUTS plug-in connector. Failure to do so may cause
damage to the CT.
Please note that incorrect connection of the current transformers could result in zero current
readings, even when the generator is on load.

Correct measurement of the current is extremely important, as the C6200 module relies upon the
current measurements for the calculation of power factors, active currents/loads, reactive
currents/loads, integrated protection functions and load sharing.
5.4 Programmable Inputs
The programmable input connector houses a number of digital inputs. The digital inputs work with
negative reference, meaning the inputs are considered active when at COM level and inactive when
left open (disconnected). The inputs are used for external activations of regulation and other
functions. The functions are described in the C6200 Configuration Manual.

5.5 Analogue Inputs
The analogue inputs are used when two busbar sections should be synchronized with each other or
with the grid. They can also be used in case the load of the generator should be remotely controlled
in grid parallel applications.
5.5.1 Volt. In
The VOLT. IN input is an analogue input. The input can be used for external control of the
generator voltage, provided that the F/V CTRL. DISABLE input is active (connected to COM). The
analogue control signal must be a voltage between -5 and 5 V DC. The VOLT. IN input uses the
COM terminal as reference. If not used, the VOLT. IN input should be connected to COM. This is
especially important while the F/V CTRL. DISABLE input is active.
5.5.2 Freq. In
The FREQ. IN input is an analogue input. The input can be used for external control of the
generator frequency provided that the F/V CTRL. DISABLE input is active (connected to COM).
The analogue control signal must be a voltage between -5 and 5 V DC. The FREQ. IN input uses
the COM terminal as reference. If not used, the FREQ. IN input should be connected to COM. This
is especially important while the F/V CTRL. DISABLE input is active.
