Dear Expert, We have belt conveyors for raw material and to protect them we use ZSS PROXIMITY switch [ZSS-zero speed sense] at belt end. If motor is ON and in this condition is it belt also moving[or elsemotor and belt mechanical arrangement is disturbed.] [ZSS fixed at conveyor to sense striker plates to generate pulse]. So if after Motor is ON and ZSS signal is unable to achive at PLC till 20sec then it will TRIP motor to stopconveyor and its series. We Need : Instead of this ZSS unit is it there another technic available ? or is it instead of this ZSScan use other instruments ? ( ZSS : --> Type IPS D3 OG NO , 10-30 V DC,PNP,200mA) AttachmentC:\Documents and Settings\11223\Desktop\ZSS.zip (85 Downloads) |
