General Information
The chassis dynamometer LPS 3000 consists of
a communication desk with PC, monitor, keyboard and wheel mouse
a remote control and
a roller set
The LPS 3000 is available in various versions for performance testing of cars. Depending on the
version, wheel power from 260 kW to 520 kW with a max. test speed of 250km/h can be tested.
The dyno load simulation is done with an eddy-current brake.
The LPS 3000 enables engine power measurements to be made on cars with Otto and diesel
engines. Testing of four wheel drive vehicles is possible if the LPS 3000 is equipped with the
appropriate roller set and the corresponding control electronics.
Description of the Remote Control
The functions of the LPS 3000 program can also be selected via the remote control. The remote
control can be operated directly from the vehicle.
The signal is transmitted by radio. The reception antenna for the signal is located in the desk.
Should several dynos each with its own remote control be operated in one room, the remote
controls must be set to different channels.
As soon as the remote control is switched on and radio connection to the dyno exists, the green
control lamp will light up permanently on the operation desk. The green control lamp will blink
briefly each time a key is pressed.
Description of the Interface Box
The interface box records engine RPM, environmental data, OBD data, temperatures, pressures
and analog signals. This is done via modules.
A max. of 4 modules can be installed in the interface box.
Additional modules can be installed in a second interface box which is connected parallel and if
desired, adapted to customer wishes.
RPM Module (Standard)
The RPM module is used to record the RPM and oil temperature
(Insert card CAN DRZ).
Following RPM sensors/RPM sources can be changed:
Trigger tongs
The RPM signal is picked up at the ignition cable (spark plug or distributor ignition coil) with the
trigger tongs. The trigger tongs should be placed as closely as possible to the spark plug and as
fars possible from the next ignition cable. The tripper tongs take up the high voltage signal
inductively which is conducted from the distributor to any random cylinder. The impulse is
relayed from the trigger tongs to the test box where it is converted to an RPM signal.
