Set the Overtemperature Alarm
2-12 Model SHKE8000 Series Shakers
Three temperature alarms are programmed into the Stackable Orbital
Shaker; Overtemperature, Undertemperature, and Tracking Limits.
The Overtemperature alarm activates whenever the operating temperature
goes above the Overtemp setpoint temperature by a few tenths of °C. This
adjustable limit is set at the factory at approximately 64°C. To change this
value, open the Configuration menu by pressing the down arrow, up arrow,
and the Silence button in that order.
When this screen opens....
Press the down arrow once ....
Then press the Temperature
button beneath Alarms.
To change the Overtemperature
alarm setting, press the Time
button beneath Over.
This screen appears and the
current Overtemperature alarm
setting flashes.
Change the Temperature setting by
pressing the up or down arrow.
When set, press the Temperature button to return to the previous screen or
press nothing for about fifteen seconds. The display will change to the
Operating Screen, saving the new settings into memory.
When the overtemperature setpoint is exceeded by a few tenths of a degree,
the control system turns the heating system off. The Overtemp Shutdown
warning displays, the warning lights
flash and the audible warning (if not
turned off ) sounds.
Pressing Silence turns off the audible alarm. However, warning lights
continue to flash and the alarm message displays until the overtemp
condition is corrected. The audible warning also sounds again in about 15
minutes if the overtemp condition persists. After the fault is corrected,
press the Silence button to clear the alarm message from the display.
