ULTRASONIC CLEANER
4.1ULTRASONIC CLEANER (P/N
4.2SPECIFICATIONS. The ultrasonic cleaner oper- ates on either 115 Vac or 230 Vac, 50/60 Hz. The mode is jumper selectable within the generator enclosure. The generator is shipped in the 115 Vac configuration.
4.3INSTALLATION. The ultrasonic generator is shipped with special cushioning material. Before open- ing the container or removing any packing material, all items should be inspected for any possible shipping damage. If any damage is found, the carrier should be notified. Check the generator enclosure for damage to the finish; loosen the door clamps and inspect the cir- cuit board and components. If there is apparent dam- age, contact the carrier for instructions. The packing container and cushioning material should be retained should it ever become necessary to return the genera- tor to the factory. Install the ultrasonic cleaner as fol- lows:
1.Mechanical Installation. Although the generator is designed to be located in a process
2.Electrical Installation. An external line switch should be installed to disconnect power from the generator for maintenance or periods of
CAUTION
Make sure the 115/230 jumpers on the transformer are in the proper position for the supply voltage being used. The gener- ator will be seriously damaged if 230 Vac is supplied with the jumpers in the 115 Vac position.
The power output is approximately 1400 volts at 0.002 amp, at a frequency of 40 to 45 kHz. The transducer is supplied with 20 feet of interconnecting cable in a polypropylene protective sheath. Output connections are made at
CAUTION
Do not run any ultrasonic cleaner power, wiring input or output, in the same conduit as the signal wiring from the sensor.
4.4OPERATION. Submerge the sensor into sample and start the sensor as instructed in Section 2.0. After measuring system is in operation, apply AC power to the ultrasonic cleaner. Over a period of time (usually several days), gradually increase the gain until the power setting is sufficient to keep the electrodes free of process buildup.
CAUTION
Increase gain slowly and apply only the necessary amount of power. Excessive power may damage the electrode. Once initial
