Gas switch AEB725A with petrol cranking - Level indication and Safety-Car relais

LPG Petrol Start Switch AEB725A - With Level Indication & Safety relais

This type of LPG switch is used in combination with classic LPG systems in vehicles with a 1st generation petrol injection system (K-jetronic L-jetronic, Monopoint, Dual point) The switch is equipped with a push button with which the type of fuel can be selected (Petrol /LPG) and a number of LEDs for the LPG tank content indication. The switch remembers the last selected position (Petrol/LPG) and when starting in LPG mode, the system starts on petrol and later switches to gas. The switch also has a built-in safety relay.

The switch is equipped with a push button with which the type of fuel can be selected (Petrol/LPG) and a number of LEDs for the LPG tank content indication.....

Optional Tank sensor: 
A tank sensor is not included with this product and depends on the type of LPG tank. Here you will find suitable 0-90 Ohm tank sensors for a 4-hole tank or for a Multivalve LPG tank.

NB! Power the switch from a fused 12V source (Max. 5A). Use an external 5-pole relay (not included) to energize the gas shut-off valves. So do not feed it directly from the switch. (See enclosed diagram).

Application and use:
The LPG switch is suitable for vehicles with petrol injection and LPG conversion with an electric vaporizer. A number of aspects can be set, such as A: the choice to switch to gas during acceleration or deceleration, B: the switchover speed: threshold speed above which the system switches to gas and C: the type of tank sensor signal for a correct content indication. The switch can be set for the following types of tank sensor signals: AEB sensor, 0-4700 Ohm sensor, 0-90 Ohm sensor, Spare Sensor. (Further refer to the instruction manual for the setting procedure.)

The built-in safety relay ensures that the gas shut-off valves close within one second after any accidental engine stop, so that the gas supply is stopped.

Correct Installation! Have this Product installed by a competent person or specialist company! Use the RDW guidelines for this. 

(For vehicles with a petrol carburettor, no AEB725A is used, but the gas start switch type AEB722A)
