Trouble-shooting（１）Basic considerable reasons
If your problem is not resolved with the list below, please contact us referring to “Warranty and After-sales services”（⑤）.

Problem

Considerable reasons / resolution
Power cord may not be connected.

Power is not turned on

Refer to “Mains and grounding” （②-P.3）.
Fuse may be blown out.
Refer to “Exchanging fuses of Oscillator” （②-P.10）.
The output knob may be in its minimum position, adjust the output knob on the front
panel. Refer to “Name of Oscillator” （②-P.1）.

Oscillation is not output

Turn on the output switch on the front panel. If oscillation outputs, the external circuit(automatic machine side) may have some troubles such as wrong connection, wire
breaking, or loose contact etc.
Refer to “Usage set on automatic machine”（②-P.4） or “Manual usage”（②-P.7）.
Over heating protection

Error performed
Emergency lamp (red) lights
and alarm buzzer sounds.
Error signal outputs toautomatic machine at thesame time.

It works when over heating is detected at Oscillator or Transducer.
Refer to “Setting of Oscillator” （②-P.3） and “Provision of cooling air” （③-P.3）.
Over load protection
It works when too much resistance, which excesses the unit’s ability and may cause
failure, is loaded during operation.
Refer to “Considerable reasons of over load stop” （④-P.9）.
Output protection
It works when Transducer is not connected normally. There may be wrong wiring or adamaged wire.

Refer to “Connection with Oscillator” （③-P.4）.

How to reset from Error?
At first turn off the power switch on the front panel of Oscillator, and keep this situation for 5 seconds, and then turnon the power switch. Then you shall complete resetting.
Unit cannot be reset fromError
Blade, Holder or Horn tool isbroken

You may be failed the above resetting completely. Try to reset again.
There may be some inadequate in attaching, cleaning or life of relevant components.
Try again to attach firmly, clean up, or exchange components, referring to“Maintenance of Transducer” （③-P.5）.

Number of lighting output The numbers indicated in “Output changeover control function”（②-P.8） is alamp is abnormal

guideline. Actual output is already changed 75% or 50% of its full function.

（２）Considerable reasons of over load stop
It works when too much resistance, which excesses the unit’s ability and may cause failure, is loaded during
operation.

If your problem cannot be resolved referring to the relevant pages indicated in the list below,
Please contact us referring to “After sale services”.

Considerable reasons
The work cannot be cut for its characteristic is notadequate or severer.
“The direction of Blade” mounted on machine differsfrom “the direction of cutting course”.
Something other than Blade contacts a cutting object.

Resolution
Re-examine the characteristic of the cutting object.

Re-examine both movement of automatic machine andTransducer.

There is no problem in strait cutting course, but over

The cutting speed may be inadequate.

load stop performs in curved cutting course.

Re-examine cutting speed for curved cutting course.

The load is larger because of attrition and/or damageof Blade.
The load is larger because of wrong attachment of

There may be problems in maintenance of Transducer.

some components.

Please refer to “Maintenance of Transducer” （③-P.5）.

The load is larger because there are some abnormalthings, oils and fats between components.
Any Blade or a tool unspecified in this manual isattached.

Transducer operates only with an adequate Blade and/ortool.
