Basic Operation
2-4
USING THE EMERGENCY STOP/DYNO SHUTDOWN
The emergency stop/dyno shutdown button is designed to deactivate the dyno
outputs whenever the button is pressed or the external E-Stop circuit is opened.
When E-Stop is activated the blowers will be turned off, the motorized carriage will
stop, and the wheel clamp will stop. The starter will be deactivated as well as the AFR
air pump and the retarder will be de-activated. If the dyno is properly equipped with
the air brake option, the air brake will be applied stopping the dyno drum. If the air
brake is not installed the drum will freewheel. During an E-Stop condition the Status
Indicator light will be flashing with two short blinks on and long pause off.
USING THE HIGH PRESSURE BLOWERS
The CPI allows the dyno operator to toggle the optional high pressure blowers on and
off from the control panel. If the E-Stop is activated the blowers will be automatically
turned off. The indicator light by each button will light up when that blower output is
turned on. If the toggle switch on the blower is turned off the blower will not operate
even if the CPI output is on.
The blower outlets on the front of the dyno are designed to only work with
Dynojet provided blowers. Connecting other electrical loads or other blowers
to the outlets on the dyno may damage the dyno and void the warranty.
If the blower indicator light on the control panel is on but the blower is not running,
perform the following steps.
1 Verify the switch on the blower is on.
2 Verify the blower power plug is firmly plugged into the dyno.
3 Verify the blower circuit breakers in the power distribution assembly.
If the button on the breaker is extended, an overload has occurred and the
breaker has tripped. Press in the breaker button to reset the breaker. If the
breaker continues to trip, contact Dynojet.
UNDERSTANDING INTERLOCKS
The interlock circuit provides inputs for normally closed switches which open when it
is not safe to run the dyno. Typically these switch inputs will be tied to safety gates
and safety switches that are required in Europe. If the Interlock circuit is open the
Status Indicator light will blink on and off with the on time equal to the off time. This
will continue until this circuit is closed or an overriding E-Stop condition is sensed. In
a dyno configured to comply with CE requirements the interlock signal will activate
the drum air brake.
