electric equipment.
Special knowledge on electric unis and safety-relevant
knowledge are prerequisite for carrying out any repair works on
ultrasonic cleaning units.
Testing equipment, tools and measuring instruments
All testing and measuring tools and instruments must be
connected to a grounded socket only.
Apart from the standard electromechanical tools the following
measuring and testing equipment is required for carrying out
the measuring and repair works described in the present
Service Manual:
For electric measuring inside the unit, e.g. resistance and
throughline measuring.
Adjusting range up to approx. 100 Nm. For tests and repair
works which require the opening of the transducer system. After
opening, the transducer system must be screwed with the
correct torque (see section Transducer system). The wrong
torque can cause malfunctions and a breakdown of the unit.
For checking the power consumption of the ultrasonic generator
and the heating.
For final checking (EN 62638): error leakage current and
ground resistance.
Power 4 Ampere or more. For the separation of the unit from
the mains and for the safe and controlled upward-adjustment of
the mains voltage.
Certain components on the electronic PCB can be damaged
through electrostatic charges. Therefore, it is absolutely
necessary for the service staff to discharge statically before
they touch the electronic PCB and to remain earthed when
handling the component.
The following items are required for arranging an ESD
protected workplace:
ESD work pad; ESD floor surface; Tools
