Old type tractor with fuel line pump
Complete set model "magnet" Article number 34.112.MAG
With this set the tractor is turned off by means of: an electric magnet.
Set is supplied with a temperature (water) transmitter as standard, but can also be supplied with a temperature (air) transmitter.
Explanation
The reason why a pull magnet must be installed on an in-line pump is because if an electric valve were to be installed in between, we would think of the sound (change in speed) of the engine as stopping, but in reality it would increase the speed again*.
This is because the time period that is fixed in the security unit is set to a certain number of seconds. When this period has expired, the electric valve opens again and the gas oil is supplied again. Then the same thing repeats as above *.
Old type tractor with fuel rotary pump
Complete set type "fuel valve" Article number: 34.112.BRA
With this set the tractor is turned off by means of: an electric fuel valve.
Set is supplied with a temperature (water) transmitter as standard, but can also be supplied with a temperature (air) transmitter.
Explanation
Because the rotating pump works with a pre-pressure from the delivery pump, an electric valve can be mounted here, because when this is closed and the pre-pressure drops, the injector pressure suddenly disappears and the engine immediately shuts down. It is not prohibited and a pull magnet can be installed, but it only makes security more expensive.
New type of tractor that can be turned off with the ignition key
Complete set type "key" Article number: 34.112.SLT
With this set the tractor is turned off by means of: the existing built-in electric valve which is interrupted via the contact.
Set is supplied with a temperature (water) transmitter as standard, but can also be supplied with a temperature (air) transmitter.
Explanation
With this type of tractor, a valve is already built into the rotating pump, which ensures that when the ignition key is turned, the built-in valve closes immediately and the tractor turns off.
When we connect the signal wire from the main box to the fuel pump, the same thing happens internally in the pump as when the key is turned. These fuel pumps are usually on tractors from recent years.
