Terms appearing frequently in this Instruction Manual
1. "Parts feeder" means generic names of such as bowl feeders and linear feeders, and for NTN products only.
2. The one only written as main body indicates “Vibration main body of parts feeder”.

3. Function and Features(1) Wide input (Applicable to wide range of power source voltage)
Input voltage range is AC100～115/200～230V±10％ (Changeover type with DIPswitch). Output voltage is
output, depending on the power source voltage and DIP switch.
(2) Constant voltage function
It curbs the influence of power source voltage fluctuation and keeps the output voltage constant. It is especially
useful when the controller is used at the site where the power source voltage fluctuation is intensive, such as asite where the electric power condition is bad and a 24 hours continuous operation.
(3) Equipped with external control input terminal
External control input terminal is equipped so as to control ON/OFF of the controller smoothly. Remote control ofdrive and stop of the controller is possible using a small relay contact. (Refer to P.14)(4) Equipped with soft start function
Soft start function is equipped so that vibration at the time of starting up changes smoothly for the case ON/OFF
control was made using the external control input terminal. Depending on application, change of 8 stages from 0
to one second is possible. (Refer to P.17)(5) Equipped with level switch input terminal (Also applicable to the separately placed hopper)
Level switch input terminal for the separately placed hopper is equipped as a standard. Therefore, it can be also
used as a controller for the separately placed hopper.
(6) Lineup of excusive types for small capacity load
When the vibration main body with small consumption current is controlled, there is such a case that it may nothelp but vibrate due to leak current of the controller even if the stop signal is entered. Small capacity load control
type, K-EGA17 is also available so as to control such a vibration main body. It is especially useful for the control oflinear feeder of S05 and S08 types. (Refer to P.22)(7) Mountable to plain surface
As a separate option part, plain surface mounting leg (K-PZ0465) is available. This is most suitable for cohesion
mounting to mounting surface or mounting to the inside of your control panel. Also, it is possible to fit to themounting leg designed by customers. (Refer to P.8)

9. Measuring method of load voltage(1) Measuring of load voltage
When measuring the load voltage, measure between terminal 1 and terminal 2 of OUT under the condition that load
is connected without fail. (Unless load is connected, power source voltage is displayed.)・In case of the analog type tester, measure twice after reversing tester bars of red and black, and make the average
as a measurement value.
・Measurement range becomes alternate current voltage range also in the case of half wave.
・Use the average value type tester for measurement without fail. The effective value type tester may not measurecorrectly the voltage of phase control wave profile. (Standard values of the next page are also ones measured by
the average value type tester.)

Warning

Refer to P.22 for the applicable fuses.
1. Switch off the main power source (main breaker) tostop the power distribution to the controller.

In case of replacing a fuse, make sure to switch
off the main power source and the work must be
performed by engineers.

2. Search the cause of blowout of a fuse and apply an appropriate countermeasure.
3. Loosen the panel fixing screw and open the panel. (Refer to P.12)
4. Remove the fuse from the fuse clip (Refer to P.6 for the location)
5. Insert a new fuse with the same rating with the blowout fuse (check such as rated current/voltage) into the fuse
clip. Dispose the blowout fuse in an appropriate manner.
6. Close the panel to the original position and fix it with screws.
7. After confirming the safety, power on the main power source (main breaker).
