• The speed of the fan motor is monitored
continuously. If the fan motor does not start up or if
the speed deviates by more than 10%, the heater is
switched off after 30 sec.
• When the heater is switched off, the glow plug is
switched on for 40 seconds (after-glowing) while the
fan runs on to clean off any combustion residues.
* The controller can be enabled again and the faults
read off:
• using the module timer
• using the radio remote control TP5.
For other controls:
• by connecting up a diagnosis unit
• using the customer service program KD2000.
For operation and fault list, please refer to the
enclosed operating instructions or the troubleshooting
and repair instructions for the heater.
Do not switch the heater off and on again more
than twice.
Forced shutdown in ADR / ADR99 mode
(only for diesel heaters)
In vehicles for the transport of dangerous goods
(e.g. tanker trucks), the heater must be switched off
before the truck drives into a danger area (refinery,
fuel service station, etc.).
Failure to comply results in the heater switching off
automatically when:
• The vehicle engine is switched off.
• An additional unit is started up (e.g. auxiliary drive
for unloading pump etc.).
• A vehicle door is opened (ADR99 regulation,
only in France).
The fan then runs on for max. 40 seconds.
Control and safety devices
• If the heater does not ignite within 90 seconds after
starting the fuel pump, the start is repeated. If the
heater still does not ignite after another 90 seconds
of pumping fuel, the heater is switched off, i.e. the
fuel supply is off and the fan runs on for approx.
4 minutes.
After an unacceptable number of failed start
attempts, the controller is locked.*
• If the flame goes off by itself during operation, the
heater is restarted. If the heater does not ignite
within 90 seconds after the fuel pump has started,
or ignites and goes off again within 15 minutes, the
heater is switched off, i.e. the fuel supply is off and
the fan runs on for approx. 4 minutes.
This status can be remedied by briefly switching off
and on again.
Do not repeat the switching off/on routine more
than twice.
• In the case of overheating, the combined sensor
(flame sensor/overheating sensor) triggers, the fuel
supply is interrupted and the heater switched off.
Once the cause of the overheating has been
eliminated, the heater can be re-started by
switching off and on again. After the heater has
been switched off for overheating an unacceptable
number of times, the controller is locked.*
• If the lower or upper voltage limit is reached, the
heater is switched off after 20 seconds.
• The heater does not start up when the glow plug is
defect or when the electric lead to the dosing pump
is interrupted.
• If the combined sensor (flame sensor / overheating
sensor) is defect or the electric lead interrupted, the
heater starts up and is then switched off again
during the start phase.

Please note!
Emergency shutdown – EMERGENCY OFF
If an emergency shutdown – EMERGENCY OFF –
is necessary during operation, proceed as follows:
