• Make sure that the emergency stop button is not
pressed.
7.2. General Precautions And Controls Which Must
Be Done After Starting Up The Generating Set
• Check for any abnormal noise or vibration on the
generating set.
• Check if the exhaust system has any leakage.
• Monitor the generating set operation by means of
the control module LCD display. Check the engine
temperature and oil pressure Oil pressure must reach
the normal value 10 seconds after the generating set
operation.
• Monitor the generating set outlet voltage and fre
-
quency by means of the control module LCD display.
Check the voltage, if the voltage between phases is
400 V. and between phase and neutral is 230 V. Volt
-
age is adjusted in the factory , do not try to readjust it.
• Check that the frequency is 51 - 52 Hz on generating
sets with mechanical governors and 50Hz on generat
-
ing sets with electronic governors.
• If an engine block water heater is not available, run
the generating set at no-load for 3-5 minutes and
when the engine warm than apply on load (for manual
models)
Apply load to the generating set as follows on manual
mode
• Set the alternator outlet circuit breaker on the panel
to ON position.
• Set the load circuit beakers (or fuses) on the distri
-
bution panel to ON position one by one. This way, the
generating set cannot be suddenly put under full load.
Otherwise, the engine stalling or alternator winding in
-
sulation of formation or burning can occur.
• Set the alternator outlet circuit breaker on the circuit
to OFF position before stop the generating set.
• Continue to run the unloaded engine for purpose of
cooling period for 2 minutes and then stop.
• Never operate the generating set before removing
any fault, if any.
• Check the oil / coolant/fuel leakage while engine is
running.
• Never run the engine below 30%of prime power
for a long time.
• Share the load on every phase (U,V,W) equally.
• On automatic controlled gen set load will be on and
off automatically.
8. LUBRICATING OIL
Oil system of diesel engine is one of the most import
-
ant elements of the engine. Correctly made engine
overhaul (this subject includes oil change periods, filter
change periods, paying attention about selecting the
true type of oil) prolongs the life cost of the engine.
8.1. Oil Performance Properties
The American Petroleum Institute (API) the American
Society for Testing and Materials (ASTM) and Society
of Automotive Engineers (SAE) has developed and
preserved a system in order to classify the lubrication
oils for their performance categories
8.2. Lubrication Oil Recommendations for Perkins
Diesel Engines
Perkins recommends that high quality multi grade
SAE 15W/40 high service engine oil in diesel engines
are used. At ambient temperatures above –15 °C is
15W40.
Only use commercial oils that meet the following class
•APICG-4
•APICH-4
