Safety features
The fuel station has various safety features that try to intercept typical operating errors. In practice, the
possible errors that occur are:
Overpressure in the tank
Forgetting at the beginning of refueling to remove the plug from the tank overflow.
Incorrectly refueling a model with bag tank with a program that has set the flowback line as a "tank full"
signal.
In these cases, the flow during refueling will drop unusually quickly. This circumstance is evaluated by
the system and can be used for shutdown. The sensitivity of this monitoring function is set via the Burst
Protection parameter in System-Settings.
If this monitoring function is triggered, the following is displayed in the upper line:
Fill-line disconnected
A refueling process is under way and the refueling hose unintentionally separates from the refueling
connection or a tank bursts. These circumstances lead to a sudden, unusual increase in the flow, which
can be utilized to end the refueling process. In this case, the pump stops and the display shows:
This monitoring function can be switched on/off via the Burst Protection parameter in System-Settings.
Fuel tank empty
If, during refueling, air is permanently detected in the refueling hose and no flow can be detected, the
system terminates the refueling process with the message:
Fuel tank overflow
If fuel is detected on the return flow sensor for at least a certain amount of time during defueling, this
normally means that the jerry can is completely full and that, instead of air, fuel is leaving the overflow.
In this case, the system ends the defueling process with the message:
