Orbital Shaker
The SHKE420HP Control Panel has a liquid crystal display and eight
operating keys or buttons which are identified by word and symbol.
During programming activities, the up and down arrows increase and
decrease the numerical values of time, platform speed, or temperature.
Pressing and holding either arrow will cause the values to scroll in that
direction. Pressing and holding for about five seconds will increase the
scrolling speed.
When programming the system configuration, the UP arrow returns the
display to the system's Operating Screen showing the Time, RPM and
Temperature, while the DOWN arrow advances the display to the next
programming screen.

The alarm indicator and alarm silence button complete the shaker control
panel. When in alarm, the unit sounds an audible warning and flashes the
three red indicators. Pressing the Silence button turns off the audible
portion of the alarm. However, the three flashing indicators continue to
flash until the alarm condition is corrected. The audible warning will
sound again in about fifteen minutes if the condition continues.
The alarm features are discussed in more detail in the Configuration
section of this manual.
The MaxQ Orbital Shaker may be operated as soon as the platform is
installed, the unit is plugged in, and turned on.
Note At power up, the screen at the right
