DIAGNOSIS
Page 565 of 1463

OM600 ENGINE ELECTRICAL 1E3-3
1. Preheating time - control relay.
Control relay functions as followings :
lSwitching of preheating current.
lIndication of preheating finish.
lControl of preheating sequence.
lIndication of fault.
2. Coolant temperature sensor.
Coolant temperature sensor senses coolant’s temperature
and signals it to the preheating relay continuously.
3. Glow plug
The glow plug parts are housing with M12 ´ 1.25 thread
and heating pin in housing. It is connected in a parallel circuit
with the specified voltage of 11.5V.
The heating element has a heating coil and a control coil
and they are connected in series.
1. Control Coil
2. Heater Coil
4. Current and temperature of glow plug
lCurrent of glow plug
While the preheating system operates, current of about
30A flows in each glow plug and temperature of heating
coil rises very fast.
Due to the rise of temperature, the resistance of control
coil increases therefore the current is controlled to
about 8~15A and that protects the glow plug from over-
heating.
lTemperature of glow plug
The temperature of the glow plug reaches up to 900°C
after about 9 seconds and up to 1,050°C after 30
seconds.
