Exchange the optical sensor OPX-1 or 2

 

 

The following procedure handles the exchange the optical sensor OPX-1 and OPX-2.

 

Used in:              Any kind of SCAN and P250

 

 

Requirements

 

·       1.5mm hex key wrench

·       Service program

 

 

In the service program

·       The magazine input sensor is named as “Left magazine sensor” and

·       The magazine output sensor is named as “Right magazine sensor”.

 

 

 

 

 

      Check the sensors before dismounting

·       Check the sensor pin for glass shards, dust or any other dirt; the pin should move very easily.

·       Check the sensor cable for right connection of the wires to the connectors

·       Check the correct cable position in the DC-Controller

·       With the service program check the functionality of the sensor and its acting path.

·       Hereby, the sensor moveable part should move very easily and the acting range should be about 0.5mm.

·       The sensor state “attached” and “released” should be clearly distinguished by the weight of the empty magazine.

 

Because the label of the sensor cable is different in the SCAN versions and in the P250, the “X” stands for the electronics version.

·       In MIRAX scanners and SCAN150 the cable label and so, the name of the sensor also, is OPC-1 and OPC-2.

·       In Pannoramic scanners the cable label is OPF-1 or OPF-2.

·       In Pannoramic 250 scanners the cable label is OPJ-1 or OPJ-2.

·       The type of the sensor, its construction and working principle is identical in all magazine unit types.

 

 

      “Magazine unit_SCAN”, “Magazine input sensor_SCAN”; “Magazine input sensor_P250”; “Power and control_Optical sensor”

 

 

 

 

 

 

Remove the appropriate sensor

 

 

The main aspect of this exchange procedure is, that the magazine unit should not be dismounted during exchange of any optical sensor.

 

·       Switch off the power supply

 

·       Disconnect the sensor cable header

 

With a 1.5mm hex key wrench remove the mounting bolt of the sensor; after this, the sensor can be easily pulled downward, out of the mounting hole.

 

 

 

 

 

 

 

 

 

 

Before mounting the sensor, check its correct switching with the service program!!

 

·       The sensor should have a very small acting range!
