1. Application information
1.1 General information
1.1.1 Genset controller description
The Genset Controller GC-1F/2 is a microprocessor-based control unit containing all necessary functions for
protection and control of a diesel engine. Furthermore, it contains a three-phase AC voltage measuring cir-
cuit. The unit is equipped with an LCD display presenting all values and alarms. GC-1F is a compact all-in-
one unit designed for the following applications:

1. Automatic engine start/stop

2. Engine protection
3. Breaker control
4. Generator protection
5. Automatic Mains Failure
6. Automatic Transfer Switch control*

GC-1F automatically carries out a cyclical self test. If any errors are found, the status relay output will deacti-
vate (normally closed). In order to save battery power, the display can be set to switch off automatically after
a given period of time. The display will turn on again if events or alarms take place, or if one of the push-
buttons is activated.

1.1.2 Setup of the controller

The parameter settings and M-Logic programming can easily be done via a PC Windows®-based utility soft-
ware (USW). The USW is password-protected - for further information please read the help file in the USW
editor.

To interface the GC-1F from the PC, there are two possibilities. One is option J5, which is RS232 with an
interface box between PC and GC-1F. The other option is J9, which is USB to TTL interface between PC and
GC-1F. Both cable options J5 and J9 are galvanically isolated and will protect your PC if it is connected dur-
ing genset operation.

The PC utility software offers additional features such as monitoring of all relevant information during commis-
sioning, saving and downloading of settings and downloading of software updates. Furthermore, the most fre-
quently used settings can be accessed via the display push-buttons, which are password-protected.

1.1.3 Language
The master language is English and, furthermore, there are three selectable languages. These are listed in
the order specifications.

1.1.4 Translation
This function makes it possible to translate all texts used in the unit.

1.1.5 Options
The options selected by the customer will be integrated in the standard GC-1F, securing the same user inter-
face regardless if the application needs are basic or a more complex genset controller.
