The "Preset Speed" help you using two digital signal to switch feeder speed that you could preset

INTRODUCTION

In the process of the auto-manufacturing, engineer need to switch between different speeds according to different materials. For convenience and easy adjustment, presetting the feeder speeds which will be remembered by the controller,  when the materials is changed, use two digital signal to Switch the corresponding speed that remembered.
I will show you how to use the "Preset Speed" function that switching the feeder speeds using two digital signal.

 READY

You need to prepare a vibratory feeder controller (Product Type: SDVC20S), 15 Pin Plug, two self-locked switch and some wires, As follows:

Figure 1: Vibratory feeder controller (Product Type: SDVC20S)

Figure 2: 15 Pin Plug 

Figure 3: two switches

THE METHOD OF WIRING

The schematic and physical diagram of wiring to the controller are as follows：

Figure 5: Physical diagram of switch wiring

The video 1 show you how to wire the switch to controller:

PRESET SPEED

The "Preset speed" can switch between four speeds and the speed is decided by the combined state of two digital signals. when switch A or switch B signal is valid, The speed A or B indicator will be Correspondingly light up, as follows table 1:

Speed	The state of Speed A Indicator and Speed B Indicator	Default Output Voltage "H"
Speed 1	Speed A  Indicator:  Dark Speed B  Indicator:  Dark	150
Speed 2	Speed A  Indicator:  Dark Speed B  Indicator:  Light	160
Speed 3	Speed A  Indicator:  Light Speed B  Indicator:  Dark	170
Speed 4	Speed A  Indicator:  Light Speed B  Indicator:  Light	180

Note: you could find the output voltage "H" LED symbol on the panel of the controller.

The video 2 show you in details how to adjust the presetting speed, as follows:

Video 2: feeder speed adjustment

Note: The adjusting speed will be remembered by the controller automatically. 

The video 3 show you in details how to switch between four speeds which have preset in the video 2, as follows :

Video 3: switching between four preset speeds

NOTE

1. The type of switch A and switch B can be NPN sensor, self-lock switch, Relay or other NPN signal.
2. The type of controller including the "Preset Speed" function are SDVC20-L, SDVC22-S, SDVC21-S, SDVC34 Series, SDVC41-M.
3. If the preset speeds over four speeds, you could use the "Remote speed" function, please click here :The "Remote speed " help you to solve the trouble that manually adjusting the feeder speed
4. Each of our products have this "Preset Speed" function.
