Controller Pump Check for PE, VE, ZEXEL

The DT-UNI enables:

– Controls distributor- and inline-type high pressure fuel pumps electronically controlled;

– Set any possible position of the spool valve;

– Work with pumps with inductive or potentiometric position transmitters;

– Monitor the feedback voltage (acknowledgement) from of the metering position sensor on the indicator;

– Control the set control voltage to the dosing unit;

– Control the current value through the dosing unit winding;

– Control the fuel temperature value in fuel injection pump

– Control the fuel advance valve position;

– Display voltage of so-called “valve advance stroke (TPS), only for ZEXEL-COVEC;

– Start the engine (Motor) directly from the DT-UNI;

– Carry out functional testing of fuel injection pumps without removing them from the car.
