WARNING: To avoid electric shock, do not remove the case cover from the
Generator. There are no user-serviceable parts inside this device.
OVERLOAD INDICATOR INSTRUCTIONS
All SONICATOR
®
XL Series generators are designed to deliver high power to the
convertor/horn assembly on a continuous basis. However, under certain extraordinary
conditions, the amount of power supplied might endanger the circuitry to the point of failure.
In order to prevent equipment failure, an overload protection feature has been built into the
XL Series generators. When the output power exceeds design specifications, the overload
light will illuminate on all models and the output will be disabled. On Model XL2020, the
following prompt will appear on the LCD display in addition to the indicator light:
"OVERLOAD REFER TO MANUAL". When overload occurs for all models, proceed with
steps 1 - 7 below:
1. Shut the unit off using main power switch.
2. Check all electrical connections.
3. Eliminate contact between horn and sample. For flow cell applications,
reduce static pressure if necessary.
4. Check tightness of horns and/or tips. Remove tips and clean threads before
tightening.
5. Check horn for cracks or excessive erosion.
6. Turn on SONICATOR
®
and follow tuning instructions. If horn/tip cannot be
tuned, replace and tune again.
7. If all preceding fails to rectify problem, consult Misonix, Inc.
