1Preface
The Littelfuse Selco C6200 FlexGen provides integrated protection, frequency stabilization, voltage
stabilization, check and automatic synchronization, active and reactive load sharing, programmable
inputs and outputs and data acquisition.
This manual describes the configuration of the C6200 FlexGen by the optional C6500 user interface
module or by PC (RS232).

2System Preparation
2.1 CAN Bus Address
The DIP-switch located on the right hand side of the C6200 FlexGen is used to set the CAN bus
address. The CAN bus address is set as a binary value on the first 4 switches. Valid CAN bus
addresses are 1 to 15.
The CAN bus address should be set according to the generator reference number.
It is advisable to assign address 1 to the first C6200 FlexGen, number 2 to the second C6200
FlexGen etc. A unique CAN bus address must be assigned to each C6200 FlexGen.
Please ensure that two or more C6200 FlexGen units do not have similar CAN bus addresses.
The binary system works on the principle described below.
Switch 1 represents the decimal value 1
Switch 2 represents the decimal value 2
Switch 3 represents the decimal value 4
Switch 4 represents the decimal value 8
Examples:
SW1

As an example, the address 1 is assigned by setting switch 1 to ON and the remaining switches to
OFF. Address 10 is assigned by setting switches 2 and 4 to ON and switches 1 and 3 to OFF. The
decimal value corresponds to the sum of the ON switch values.

3Auxiliary Commands
The C6200 FlexGen is configured using clear text commands. These commands are issued through
the RS232 interface using either a PC based terminal emulator (TTY terminal) such as
HyperTerminal. Littlefuse Selco also offers a specialized PC application called WinConfig.
The optional Littelfuse Selco C6500 user interface can also be used to monitor and configure the
C6200 FlexGen.
The commands described in this section are used to read out the configuration, measurements and
alarms. This section also describes how to switch the unit into write enabled mode.
The configuration itself is described in section 4.
3.1.1 Read Measurements
The following command show all measured and calculated parameters. Please note that the reading
do not changes automatically. Retype the command to update the measurements.
READ MEAS
3.1.2 Read PMS
The command READ PMS shows the current state of the load depending start/stop system.
READ PMS
3.1.3 Read Alarms
Active alarms (e.g. fault conditions) will be show if the following command is issued.
READ ALARMS
3.1.4 Read Configuration
The READ CONFIG command dumps the current configuration of the C6200 FlexGen. The
configuration is made up from a series of commands. Each command can be issued in the form
shown, provided that the C6200 has been enabled to operate in write mode.
READ CONFIG
3.1.5 Read Event Log
C6200 saves the last XX events in an alarm log. This alarm log can be read out by following
command:
READ LOG
3.1.6 Set the date
Current date for the event log can be set by following command.
DATE
The unit will reply with following prompt:

C6200 FlexGen
Revision: 20-10-2017 Page 10 of 73
Now type the date in the requested format (Year:Month:Day e.g. 2008:09:03).
3.1.7 Set the time
Current time for the event log can be set by following command.
TIME
The unit will reply with following prompt:
Now type the time in the requested format (Hour:Minute:Second e.g. 14:02:39).
3.1.8 Enable Configuration Write mode
By default the C6200 FlexGen will be in read only mode. This means that the configuration can be
viewed and dumped but not written or updated.
The C6200 must be enabled for writing before any attempt is made to update the configuration. The
command to enable write mode is ENABLE.
ENABLE
Enable mode will prompt for the RS232 PIN. The default RS232 PIN is 0000 (four zeros).
3.1.9 Disable Configuration Write mode
To change back from configuration write mode or from service mode, use following command:
DISABLE
Please note that the RS232 console PIN is unique for each module. Also, the RS232 PIN is different
from the menu PIN of the C6500 User interface.
3.1.10 Enable Service mode
The service parameters (SERVICE INTERVAL, DUTYHOUR and SERVICE CONFIRM) are
protected with a separate PIN.
Use the following command to enable the service functions.
SERVICE ENABLE
3.1.11 Service Parameters
The service information (running hours of the generator and amount of running hours until the next
service) can be viewed by issuing the following command.
READ SERVICE
