MaxQ SHKE8000 Series Shakers
The control panel on these units has a liquid crystal display and eight
operating buttons that are identified by word and symbol. During
programming, the up and down arrows increase and decrease the
numerical values of time, platform speed, or temperature. Press and hold
either arrow to cause values to scroll in that direction; hold for more than
five seconds to increase scrolling speed.
When changing the system configuration, the down arrow advances the
display to the next screen, while the up arrow returns the display to the
previous screen. Pressing the Time, Speed and Temperature button selects
the parameter above it to be changed, while the up and down arrows
increase and decrease the numerical values, respectively, or toggle between
two different options. Pressing and holding either arrow will cause the
values to scroll in that direction. Pressing and holding for more than 5
seconds increases the scrolling speed.
The START button begins platform operation as defined by the Time and
Speed setpoints, while the STOP button halts the platform. Chamber
temperature begins upon power-up as defined by the Temp setpoint.
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. Depending on the error detected, pressing the Silence
button turns off the audible alarm. However, the three red indicators
continue to flash until the alarm condition is corrected. For most alarms,
the audible warning will sound again in about fifteen minutes, if the
condition is not corrected.
Alarm features are discussed in detail later in this section.
