3.2.5 Check battery
Only KDE6500T-6700T/TA generating set
is equipped a 12V36AH maintenance-free
battery as factory standard configuration.
Check the battery capacity every month
when in use. Measure the voltage of battery,
it should not lower than 11.5V. Otherwise
the generating set will not start. Check the
charging circuit for fault.
It should be noted for customer of other generating set, that if his self-equipped
battery is not a maintenance-free battery, he should check the battery electrolyte
level every month. Refill the distilled water until the upper limits if the electrolyte
dropped to the lower limits.
In installing battery, the generating set should be stopped. Set the battery to be
installed beside the generating set. Take out positive and negative connecting
post of battery provided with generating set. Fix them to the positive and negative
poles of battery respectively. Take out positive (red) and negative (black)
connecting harness of battery. Secure them to the positive and negative poles on
battery terminal post. Then put the battery onto the battery holder of generating
set. Secure it with battery clamping plate and bolt provided with generating set.
(2) For generating set equipped with low oil alerting system, check that the low oil
indicating lamp is not on.
ATTENDED
If the electrolyte level is too low, the engine may fail to start because there is
not sufficient electricity. On the other side, if the electrolyte level is too high,
the fluid will corrode the surrounding parts. Do keep the electrolyte level
between the upper and lower limits.
3.2.6 Checks during the running
(1) Whether there is abnormal sound or vibration in generator.
(2) Whether the engine runs rough.
(3) Check the color of exhaust. (Is it black or too white?)
If you notice any of the above-mentioned phenomenon happened, stop the
engine and find out the fault cause according to troubleshooting.
3.2.6.1 Check A.C.Output Characteristic
(1) Be sure to run the generating set at rated speed, otherwise the automatic
voltage regulator (AVR) will produce the forced excitation. If the running is for a
long time under such condition, AVR will be burned out.
(2) After switching on the air switch, observe the voltmeter on the panel of the
control cabinet, the voltmeter should point to 230 V (50 Hz), 120/240 V (60 Hz)
for single-phase generating set; 400 V (50 Hz), 416 V (60 Hz) for three-phase
generating set, then the loading can be carried out.
(3) Connect the equipments to the generating set in order. For the matter of the
motor load, firstly the heavy-duty motor should be connected, then the light-duty
motors. If the operation is false, the generating set will lag or stop suddenly. It is
necessary to unload the generating set immediately and turn off the main switch
and do checks
3.2.6.2 DC checks
(1) DC terminals are only for charging 12 V battery.
(2) Set the air switch at OFF position while charging. On the 12 V output
terminals a charge switch can be connected so the switch can be used for on-
and-off purpose..
ATTENDED
When the oil pressure is too low or the engine oil level is too low, the low oil
alerting system will act to stop the engine. If no engine oil is refilled, the
engine will not restart. Please check engine oil level first, then refill engine oil.
Never loosen or adjust engine speed limiting bolt and fuel oil limiting bolt.
ATTENDED
If overloading of the circuit trips the AC circuit air switch, reduce the
electrical load on the circuit, and wait a few minutes before resuming
operation.
