3.Working principle

The protector consists of light curtain,signal cables,controller and control cables.The light curtain can form infrard light curtain,detect the signal of passing or intercepting,and send the signal to control box that also supplies power to the light curtain.The control box processes the signal and outputs the closed or opened signal used safety relay,and then connects the control trip circuit of the press by control cable or other protective equipment to protect the workers

4.Detailed introduction

(1)STQ series is based on STD series,using 1 or 2 mirrors to reflect the beams,changing the transmissive direction of the beams,forming 2 or 3 sides protected zone.

(2)Light curtain form:Plane mirror reflect(3)Standard configuration:

    2 sides protection:Emitter/1,Mirror/1,Receiver/1,Wtype controller/1,Signal cable 3 m/1 root,10m/1       root,Installation fittings/1 set,model indication.

    3 sides protection:Emitter/1,Mirror/2,Receiver/1,Wtype controller/1,Signal cable 3 m/1 root,10m/1 root,Installation fittings/1 set,model indication.

(4)It is allowed to choose N type controller.

(5)Controller:W type, outside installation,control 1 set light curtain,the power source is AC220V/110V(switch conversion) or DC24V; N type, inside installation,control 1 set light curtain,the power source is AC220V/110V(terminals) or DC24V; controller cable is equipped with standard length: N type 1.0m ,W type 2.5m(6)It can provide NPN ,PNP output, at this time, we should guarantee the follow-up control circuit correspond to safety requirements and provide DC24V power source.(7)Prompts specially:If the power source need to be DC24V,the special explanation should be made on order.If the length of signal and controller cables need to lengthen,the special explanation should be made on order5. Application examples
