table, a tolerance of
±
10% applies at an ambient tempera-
ture of +20°C and at the rated voltage and conditions.
Electrical Components:
Control unit, motor, fuel metering pump, light bulb in the
digital timer* and pencil-type glow plug are designed either
for 12-volt or 24-volt operation.
The digital timer*, temperature limiter and flame detector
are voltage-independent components.
* Presetting of heater operating times is not possible for
