Additional Functions (cont.)-
An ‘Auto Brake’ output is available that can directly operate a relay for an automatic brake for slowing the flywheel down
if you wish, or an automatic cooling fan for cooling friction style brakes. The time it’s active for after a test Run is
adjustable in the software. The output can alternatively be operated manually in the software and will be active for either
a short time or continuously.
A ‘user controlled’ output is available can directly operate a relay, it is manually turned on or off from the software and
can be used for any general purpose function e.g. remotely turning on a cooling fan, pumps wheel clamps etc.
Tools to work out the moment of inertia of your dyno system, calibrate non linear sensors, convert air:fuel ratios to
Lambda and for analysing relationships between Power / Torque / RPM are incorporated.
Keyboard ‘shortcuts’ assist with easy operation and an inexpensive and commercially available wireless keyboard or
even a remote ‘page turner’ (the device often seen used for PowerPoint presentations) can be used as a remote control
that can start/stop Runs, turn the gauges on/off and allow automatic file incrementing (no need to type in a new name).
Very convenient if operating both the vehicle and the dyno single handedly.
Load Control Options (EC and PC units)-
For controlling a brake type dyno in ‘closed loop’ mode we have available additional modules that connect into the
DYNertia3 unit.
There is an Eddy current power supply unit that provides the high voltage DC required by the eddy brake (retarder) and
also available is a unit with PWM output for alternative dyno types.
The load control option allows full closed loop control of the dyno. You can set a target RPM/speed to maintain it or
perform ramp and step testing.
Control of an electronic throttle servo is also possible with either load controller option. The ‘servo pulse’ output can be
used with conventional servo motors and allows integration of the throttle for either manual control or integrated into the
test procedure.
