Operation
Cycle Complete
Cycle Complete alerts the operator that
the end of the count-down running time
has been reached. The Cycle Complete message displays and the platform
stops. Chamber temperature is controlled by the Hold Temperature
setpoint (SHKE8000-7 & SHKE8000-8CE).
Pressing the Silence button clears the alarm message from the display
screen and mutes the audible alarm.
Power Failure
Power Failure alerts the operator that
electrical power to the unit was
interrupted, under specific operating conditions. While the system returns
to normal operation when power is restored, the alarm message remains
and the audible tone continues to sound. Both the display message and the
audible tone are cleared by pressing the Silence button.
Note The alarm will not occur if the power failure is less than 15 seconds
s
in duration while the unit is shaking.
If power is interrupted for 1½ hours while the unit is turned on but not
shaking, a Power Failure alarm will occur. The purpose of the alarm in this
case is to alert the user that an extended duration power failure occurred
during the Hold interval after a timed shaking operation (SHKE8000-7 &
SHKE8000-8CE), or during a period of incubation only. This alarm will
also occur any time the unit is turned on after being turned off for more
than 1½ hours (such as when the unit is shipped from the factory, or
when it is returned to use after a period of storage).
RPM Tracking
RPM Tracking alerts the operator
consistently for at least 2 minutes by the
appropriate alarm message (as shown at
right), that the platform speed has varied
±5 RPM.
In the alarm state, the audible alarm is muted by pressing the Silence
button, but will ring back in about 15 minutes if the alarm condition is
still present. However, the alarm message and indicator lights persist until
the fault is corrected. Afterward, the remaining relevent alarm components
are cleared by pressing the Silence button.
