* 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 troubleshoo-
ting and repair instructions for the heater.
• Do not switch the heater off and on again more
than twice.
• Fault display signals can be accessed with an
additional device, see troubleshooting instructions.
Forced shut-down for ADR / ADR99 operation
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.
• The flame is monitored by the flame sensor, and the
maximum tolerable temperature by the overheating
sensor. Both influence the controller which switches
the heater off in the case of any defects.
• 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 pump stops and the fan runs on for
approx. 3 minutes.
• 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 10 minutes, the heater is switched off,
i.e. the fuel pump stops and the fan runs on for
approx. 3 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 overheating sensor
triggers, the fuel supply is interrupted and the
heater switched off. If overheating has caused the
heater to be switched off, the switch-on control
lamp (green) in the operating device flashes at
uniform intervals.
Once the cause of overheating has been eliminated,
the heater can be started again by switching off and
on again.
• If the lower or upper voltage limit is reached, the
heater is switched off.
• The heater does not start up when the glow plug is
defect or when the electric lead to the dosing pump
is interrupted.
• During the start procedure, the function of the fan
motor is checked once. If the fan motor does not
start, the heater switches off.
During operation, the fan motor is monitored in
cycles (4 min.). If the motor speed is below the
permitted limit, the heater switches off.
