4.9.4. Oil-pressure sensor
The optionally available oil pressure sensor (order: ZSPMOT00003)
is attached to the crankcase cover. To attach it, remove the blind
screw first (see diagram).

The sensor is equipped with a switch, which opens at 1,1bar oil
pressure (and is closed below 0,9bar).
4.9.4.1. Schematics of oil-pressure sensor-lamp
The easiest wiring of the oil-pressure sensor is by using a 12V lamp.
Disadvantage:
The lamp only lights up when there is too little oil. A sudden fall in
oil-pressure cannot be measured.

4.9.4.2. Oil-pressure sensor with magnetic valve
Optionally, you can use an injection pump with an integrated mag-
netic valve in the series ED4-0306 and ED4-0418.
This magnetic valve can be connected to the oil-pressure-sensor in
such fashion, that the motor stops automatically when there is too
little oil. In order to ensure that the engine always stops, even if there
is just a short disruption in oil pressure, a small circuit-board must
be integrated. You can find the up-to-date wiring schematics on our
website. We offer all the necessary parts, including the board.
