Abstract

A control system for a central lubrication system with an electrically operated lubrication pump for vehicles without their own power source, such as trailers, carriers for utility vehicle, etc., includes an electrical time-controlling device to activate the lubrication pump as a function of the operating time of the vehicle. Power is supplied to the time-controller device and the drive motor for the lubrication pump via the feed lines for the brake light. The time-controlling device has a sensor which detects motion of the vehicle or parts of the vehicle and generates a signal for a second timer during such motion. The second timer adds the durations of the signals sent from the sensor, compares the sum of the durations to a predefined pause time and, when the predefined pause time is exceeded, sends a signal to a third timer, which is thus enabled and in turn sends an enable signal for the activation of the drive motor of the lubrication pump during the next braking operation; the third timing signal adds the durations of successive braking operations during which the drive motor of the lubrication pump is activated, compares the sum of the durations with a predefined operating t…
