Sonics VCF1500HV - Manual (Page 14)

SECTION III – SERVICE INFORMATION
Your Ultrasonic Processor was designed to provide you with years of safe and
dependable service. Nevertheless, because of component failure or improper usage, the
possibility does exist that it might not perform, as it should, shut down due to an overload
condition or that it will stop working all together. The most probable causes for
malfunction are listed below and should be investigated.
The unit was plugged into an electrical outlet that provides a different voltage from
that required. See Electrical Requirements.
The probe is not secured properly to the converter.
A fuse(s) has failed. If a fuse(s) has failed, proceed as follows:
1. Ensure that the POWER switch is set to OFF.
2. Replace the fuse(s).
3. Drain the High Volume Flow Cell completely.
4. Set the AMPLITUDE control to 50, the POWER switch back to ON, and depress
the TEST switch. The power monitor should read below 20%. If the reading
exceeds 20%, set the POWER switch to OFF, and disconnect the probe from the
converter.
5. Set the POWER switch back to ON and depress the TEST switch. If the power
monitor reads below 20%, the probe has failed or is out of tune due to excessive
erosion, and should be replaced, if the power monitor reads above 20%, either the
converter or power supply has failed. The Ultrasonic Processor together with the
High Volume Flow Cell should be returned for repair.
