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.
Control and safety devices
• If the heater does not ignite within 90 seconds after
starting the fuel pump, the start is reapeated. 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. 3
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. 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 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 an unacceptable
number of failed start attempts, 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.
• When the heater is switched off, the glow plug is
switched on for 20 seconds (after glowing) while the
fan runs on to clean off any combustion residues.
Do not repeat the switching off / on routine more than
twice.
Please note!
Emergency shutdown – EMERGENCY OFF
If an emergency shutdown – EMERGENCY OFF – is
necessary during operation, proceed as follows:
• Switch the heater off at the control element or
• pull the fuse out or
• disconnect the heater from the battery.
