2. Frequency Protection:
50Hz (45~55)Hz
60Hz (55~65)Hz
When the set value is exceeded, frequency LED starts flashing; after 7 ,seconds delay in case of
under frequency and 3 seconds delay in case of over frequency , alarm shutdown is initiated. After
that frequency LED continues to flash and shows pre-alarm value.
3. Overload Protection
If the set value is exceeded by 5% or less, alarm will not be initiated;
If the set value is exceeded by more than 5%, power LED will start flashing;
If the set value is exceeded by 5-7.5% and continuous for more than 3 hours, then alarm shutdown
will be initiated;
If the set value is exceeded by 7.5-10% and continues for more than 1 hours, alarm shutdown will
be initiated;
If the set value is exceeded by more than 10%, the gen-set will be shut down immediately
(approximately 2 seconds);
After alarm shutdown is initiated power LED continues to flash and shows pre-alarm value.
4. Low Oil Pressure Protection
Irrespective of whether auto protection mode is enabled or not, low oil pressure will lead to
automatic disconnection of oil circuit; 5 High engine temperature protection.
If engine temperature exceeds 108 , LED window starts flashing; after 7 second delay , protection
begins; LED window continues to flash and shows pre-protection value (for air-cooled engine);
5. High Engine Temperature Protection
If engine temperature exceeds 98 , LED window starts flashing; after 7 second delay, protection
begins; LED window continues to flash and shows pre-protection value (for air-cooled engine);
NOTE: During Safety On delay, protection is disabled; after Safety On Delay, when voltage,
frequency, overload, high temperature protection is initiated, fuel output deactivates.
WARNING: When the engine is running, start battery must not be removed.
