Electrical Connections
A schematic of the 10-30 VDC trailer timer is shown below. The timer itself is permanently
sealed (potted) with the trailer timer enclosure.
Power and ground are connected via Deutsch DT sealed connectors.
A second connection is available for an optional low-level sensor. The 3 wires provide a sensor
with power, ground, and a return signal contact for the timer. The sensor may be ordered
separately and can be connected to the pump with no need for programming. When installing a
proximity sensor adhere to the safety precautions as previously listed on page 68.
