KS1 Digital Control Panel Programming through Micro-Switches
Programming through Micro-Switches Through the micro-switches which are located in the upper rear part of the controller we can program different parameters as follows: 1
This process described above is valid for generator set frequency detection as well as Pick-up detection.
Cooling (ENF) Micro-switch “5” allows selection if we want to program a cooling time for 60 seconds in the ‘ON’ position or 5 seconds in ‘OFF’ position.
Overspeed Activation and Programming To establish the frequency value when over speed protection should activate, it is necessary to start the generator set and wait for the generator set to be stable. Once the generator set is working at nominal frequency, we must change the switch “1” to “ON” position. Afterwards, over speed LED will light for one second approx. to indicate that the programming of this parameter has been successful. From this moment, over speed detection is active. To disable this protection, we must switch it off.

Engine Running Detection by D+ (LD+) Micro-switch ‘6’ is in ‘ON’ position, we are selecting the ‘engine running’ detection by reading the D+ (Battery-charger alternator). In ‘OFF’ position, detection will be made only by the reading of the frequency (Generator or Pick-up).
Note: Engine running detection is always made by Means of frequency reading, either by generator or Pick-up. Activating this micro-switch, we add the detection by D+. in this case, ‘engine running’ detection is made simultaneously by the reading of frequency and D+.
Frequency Reading by Generator or Pick-up (G/P) By means of this micro-switch we can choose the detection to be done by using the generator or pickup. For reading by means of the generator it is necessary to set the micro-switch ‘2’ in ‘ON’ position. To select the reading by Pick-up, it is necessary to switch it off.
Note: It is very important to connect only one of the two different frequency reading inputs. If the alternator phase and neutral to the generator input in the control panel, it will not be possible to connect the Pick-up cables to the corresponding input under any circumstances and vice versa. 3
Fuel Reserve (FR). Alarm/Stop It allows to select the action after detecting the fuel reserve alarm. By means of the micro-switch ‘3’ set in ‘ON’ position, when the alarm is detected, the corresponding optical LED activates and initiates a programmable stop cycle. In ‘OFF’ position, this alarm is indicated only by optical signal
4
Pre-heating (PR) Micro-switch ‘4’ allows selection whether we want to program a pre-heating time of 15 seconds in the ‘ON’ position or 5 seconds when the position is ’OFF’.
