Additional counters for "Running hours" and "Energy" can be read out from the PC utility soft-
ware.

7.25 M-Logic

The M-Logic functionality is included in the unit and is not an option-dependent function.
M-Logic is used to execute different commands at predefined conditions. M-Logic is not a PLC but substitutes
one, if only very simple commands are needed.
M-Logic is a simple tool based on logic events. One or more input conditions are defined, and at the activa-
tion of those inputs, the defined output will occur. A great variety of inputs can be selected, such as digital
inputs, alarm conditions and running conditions. A variety of the outputs can also be selected, such as relay
outputs, change of genset modes and change of running modes.
The M-Logic is part of the PC utility software, and as such, it can only be configured in the PC
utility software and not via the display. Please see the M-Logic manual which is available at .
The main purpose of M-Logic is to give the operator/designer more flexible possibilities of operating the gen-
erator control system.
Please refer to the "Help" function in the PC utility software for a full description of this config-
uration tool.

7.26 Buzzer

7.26.1 Buzzer
The CGC 400 has a built-in buzzer. The buzzer is configured in M-Logic. This means that if the buzzer is
going to be used as a horn annunciator, the input must be set to "Horn" and the output must be set to "Buz-
zer". The buzzer will act concurrently to the horn output timer. If the delay timer in M-Logic is used, the buzzer
will be active after this time delay.

7.27 USW communication

7.27.1 USW communication
It is possible to communicate with the unit via the PC utility software. The purpose is to be able to remote-
monitor and control the genset application.
If setting 9020 is set to 1, the PC utility software cannot communicate with the unit when it is
connected directly to the PC and a modem is not used.
Application settings
Please refer to the PC utility software help file.
Safety
If communication fails, the unit will operate according to the received data. If e.g. only half of the parameter
file has been downloaded when the communication is interrupted, the unit will use this actual data.
