● This product can only be applied to piezoelectric-type parts feeders.

● Do not use this product in a place exposed to explosive or flammable materials.

Otherwise, there is a risk of fire or explosion.

● Do not use this product in dusty or humid places.

This is neither a waterproof nor dust-proof product. Especially, an extra dust-protection

measure is required in a place exposed to large amounts of metallic dust.

● Do not turn on and off the input power switch frequently.

Otherwise, unexpected troubles may occur due to rapid heat deterioration of the internal

electronic components.

In particular, never use an electronic relay for switching the input power of this

product for the purpose of controlling on/off operations of the parts feeder (the EXTON

terminal must be used for controlling external signals).

● Do not perform on/off operations on the output side .

No electronic relay should be used to operate or shutdown the driving parts on the output

side in order to avoid any damage to the controller (the EXTON terminal must be used for

controlling external signals) .

● Do not apply welding processing work to the feeder when the driving parts are connected

with the controller.

The current leaking from welding work may damage the controller.

● Do not use the output of a PWM inverter as input power for this product.

This may damage the product.

● The input and output power must remain within the range of the rated current and voltage.

● Do not disassemble, repair, or alter the product in an inappropriate manner.

This may damage the product or cause malfunction.

● Wiring work should be performed after disconnecting the power supply.

Otherwise, the product may be damaged or the operator may be exposed to the risk of an

electric shock.

● The grounding terminal of the input and output power must be grounded.

This reduces electrical noise and the risk of an electric shock in the event of a short

circuit.

<Cautions>

1.Be sure to disconnect the input power prior to removing the cover.

2.The grounds (FG: frame ground) of the input and output power terminals must be grounded in

order to prevent electric shocks or to guarantee stable operation.

Stable operation of constant amplitude/auto tuning functions -- especially, triggered by the

feedback sensor (vibration sensor)--will not be guaranteed, if the grounds are not grounded.

3.Operation must be performed with the cover closed.

The connecting procedure for the connector is as follows:

① Input and output power, including other necessary accessory devices, should be connected

with the product in reference to the figure below.

② The setting of the overflow sensor (NPN/PNP) should be performed after opening the cover on

the right side.

This product can be used without any mechanical or electrical settings regarding the input

power as it supports a wide range of operating voltages (100V ~ 240V AC).

Pressing the FBK key for more than 3 seconds triggers a warning

beep and the FBK LED continues to remain turned on or off (disabled)

or flashes (enabled) repeatedly.

◆ When the constant amplitude operation function is disabled:

The 'FBK' LED will be turned off.

.Although the FB sensor is connected with the system, but the

constant amplitude operation function is disabled

◆ When the constant amplitude operation function is enabled:

The FBK LED will be turned on or blink.

.The constant amplitude operation function has been activated.

※ This function is only available when a FB sensor is connected with the system

(refer to page 17).

If the system is not connected with a FB sensor, the FBK LED remains turned on.

※ If the operation of the system is performed without mounting a vibration sensor on the

vibrator (albeit the sensor is connected with the controller), the constant amplitude

operation function must be "disabled."

after entering Voltage Setting mode by pressing the SET/VF key.

2.'Enter Frequency Setting mode by pressing the SET/VF key

again, and then press the RUN key in order to enter RUN

mode at a frequency of 400 Hz.

3.Find a point of the strongest vibration at a constant voltage,

while lowering the frequencies.

.More than two vibration points can be found. If this is the

case, choose the strongest vibration point.

.If vibration is too strong, reduce the voltage and

then find the strongest vibration point.

※ The frequency at which maximum vibrationoccurs at a constant voltage is the resonancefrequency.

4. If the strongest vibration point is found by changing frequencies at a constant voltage,

calibrate the vibration to obtain an optimal amount of vibration.

※ As large fluctuations in vibration may occur at the resonance point, a frequency higher

than the resonance point should be selected if the constant amplitude function is not

working.

replaced by the current operating values.

.Frequencies and all other parameters, except for voltages, should be identical prior to

saving them to each channel, if only changes in speed can be controlled.

.The channel number selected on the screen is briefly displayed as "CH-Ox" whenever there is

a change in operation modes.

In this mode, the use of an external VR is automatically disabled.

7.5 Operation Synchronization Output Signals (SYNC)

The contact point signals corresponding to the operation and shutdown status of the controller

is printed.

.Used for interlocking the hopper with the bowl feeder.

7.6 Constant Amplitude Sensor Connection (FBSN)

Connecting a vibration sensor with the FBSN connector automatically activates the constant

amplitude function.

To intentionally disable this function, refer to "Enabling and Disabling of Constant Amplitude

Operation Function (FBK)" on page 10 hereof.

Error code Cause Recommended solution

Err01 □ EEPROM write error

.EEPROM write error.Requires repairs

Err03

□ Overheating or overcurrent

.The internal heat sink is

overheated

.A current exceeding the rated

amperage capacity flows

.Turn off the power and remove the cause of

overheating, and then use the system after

sufficiently cooling the system by natural

cooling

.Turn off the power and remove the cause of

overcurrent before use

Err05□ A hugely erroneous feedback

sensor level

.The vibration of the FB sensor

is too strong

.The sensor output levels should be adjusted

by changing the position or direction of

the FB sensor

10.Protection functions and alarms

The protective functions of this product is activated in the event of an error due to a user's

mishandling or an environmental factor, displaying the corresponding error code on the screen

and generating an alarm.
