Model 416/430 Orbital Shaker control system monitors and provides
alarms for six operating parameters.

Both audible and visual alarm warnings for these six parameters are
provided by the Orbital Shaker. Visual flashing of the three diagonal
indicator lights on the control panel, a progression of text messages on the
display, and an audible tone alerts the operator that an alarm condition has
occurred, or currently exists. For convenience, the audible tone is silenced
by pressing the Silence button, but will ring back in about 15 minutes.
However, the alarm warning indicator lights and alarm messages continue
until the alarm condition is corrected by the operator. Then, pressing the
Silence button clears the message from the display. (The Check Belt and
Check Fuse alarm messages clear when power to the unit is cycled OFF,
then ON.) As discussed in the Configuration Section of this manual, the
audible alarm feature may be turned off to suit operator or laboratory
needs. Refer also to the alarms and corrective actions chart in the Service
section of this manual.
Cycle Complete alerts the operator that the end of the countdown running
time has been reached.
The Cycle Complete message shown will
be displayed and the shaker will stop.
Pressing the Silence button clears the message from the display screen.
