DAF 95XF Свечи накаливания


3. GLOW PLUGS / GLOWING / AFTERGLOWING
GLOWING

Glowing is only required if the outside
temperature is below 5°C.
Automatic (16/232)
The automatic preglowing time is factory set to
45 seconds.
To protect the glow filaments against
overheating, the circuit of this engine type
contains a thermal protection switch (E550). The
thermal protection switch opens at 110 -125°C.
Afterglowing
The after-glowing function is applied in Euro-2
engines. The glowing time is factory set to 120
seconds. Afterglowing is started approx.
3 seconds after loss of voltage at connection
point 45 (starting signal).
Afterglowing only takes place if:
- Preglowing has taken place.
- The engine speed exceeds approx.
400 rpm.
- The supply voltage (battery voltage) to the
CTE unit exceeds 17 V.
During afterglowing the CTE unit checks both
the engine speed and the supply voltage. If the
engine speed falls below approx. 400 rpm of if
the supply voltage (battery voltage) falls below
approx. 17 V, the afterglowing is interrupted.
Glowing while starting
During a “starting” action voltage is applied to
pin 45 of the CTE-2 through wire 4002.
Depending on the condition (engine speed
exceeding (6/232) approx. 400 rpm and supply
voltage (battery voltage) (42/232) on the CTE
unit exceeding 17 V), glowing is applied during
starting on the understanding that preglowing
has taken place first.
VARIANTS
Location
21 Component E550 is not present in VF
engines.
41 Wire 4009 only applies in the case of a VF
engine.
