3 Single Rotor Dynamometer Extent of supply Eddy current dynamometer with trunnion supports, is fitted on to the main base. The whole unit is supported by a machined base to be fixed to the floor. Dynamometer shaft rotation direction: reversible. Double Rotor Dynamometer Dynamometer shaft and trunnion bearings : are grease lubricated. All our dynamometers are fitted with two shaft outputs, each with a flange to connect the engine to be tested. Sealed electronic load cell installed between brake carcass and base. Pick-up to detect the engine speed (with toothed wheel, 60 teeth). Triple Rotor Dynamometer Calibration system consisting of two arms, standard length of calibration arms for torque measurement: in Nm. Closed water supply system, to be connected to the main water system. Safeties on the cooling system: PT100 thermal resistances Differential pressure switch Electric box with multicore cable and connectors (standard length 10 metres), Quadri Rotor Dynamometer Shaft guard for engine dynamometer drive shaft (not included in the standard supply of the dynamometer: supplied with the drive shaft, or at customer request, with additional cost). The standard colour is RAL 7032 for the dyno, RAL 2004 for guards. On request of customer are possible all colours. At the customer request, dynamometer can be painted a different colour- Final test, at our test cell, with engine. Eddy Current Brakes Depliant_2015 Page 3 of 41

5 DIGITAL CONTROL MODULES FOR ACCELERATORS THROTTLE CONTROLLER MP 2020 This unit is used to control our range of throttle actuators in several operating modes: a = Position n = K : Constant Speed M = K: Constant Speed Depending on the mechanical unit, the following performance are available: Speed: mm/s Force: N Travel: mm Accuracy: > 0.2 % The device is composed of these elements: Control unit (MP 2002) : It is a device equipped with a micro controller and own firmware. Its task is to communicate with the supervision PC. This PC can be connected using a mixed digital/analogue interface. This unit coordinates the operation of the power unit, manages the adjusting loops to enable speed or torque controls of the units connected. This units receives from the dyno and process the following data: Engine rpm Dyno Torque Throttle position These information are available to the PC supervisor interface through proper analogue signals.

6 THROTTLE ACTUATORS SAW It is composed by a group of mechanical actuation and includes a linear d.c. servo motor for optimum dynamic performances. To allow a quick and easy calibration of throttle actuator stroke, the mechanical unit includes two pushbuttons which are used to increase and decrease the throttle opening (from Idle to WOT and back). In this way the operator can easily meet the appropriate travel of the engine in few minutes. The main characteristics of the mechanical unit are: Max. force 170 N Permanent force 46 N Max. stroke 100 mm Max. acceleration 268 m/s² Max. speed 2.6 m/s Positioning repeatability ± 0.1 mm Linearity ± 0.4 % SAR Consists of a group of mechanics and implementation includes a brushless AC servo rotary with excellent dynamic performance. The main characteristics of the mechanical unit are: Pull-in torque 22 Nm Continuous torque 9,1 Nm Operational angle <=90 Toll. ±0,5 Peak speed 0,3/90 sec (625 rpm) Positioning accuracy ± 0,75 min di arco Absolute accuracy 1/4096 rev.
