2086 – Oil Clamp / Unclamp Device Error (A 18.6)

           

           The oil Clamp / Unclamp device is a pressure switch which ensures the pressure delivering to the axis pixels is enough to hold the work piece. If this pressure is less than the desired value it may causes to severe accident. So, the Clamp / Unclamp pressure switch generates a signal when the pressure the less and results in alarm.

                                     

When this alarm occurred do the following

         1.First ensure the pressure setting of the pressure switch is correct ( if it is more than the desired, set it)

        

         2.The electric relay which operates the solenoid valve is not working. (Check the relay output, we can find the output in PMC signal status).

                                 Y6.0 – M33 Clamp

                                 Y6.1 – M34 Unclamp

          3.The solenoid which performs the Clamp / Unclamps operations is not working.

          4.The pressure switch itself is defective.(We can find the feedback if the pressure switches in PMC Signal Status)

                   For 4^th axis : X10.4 – M33 Clamp limit Switch (M33AFN)

                               X10.2 – M34 unclamp Push Button (M34SW)

                    For 5^th axis : X11.3 – M33 Clamp Limit Switch (M33BFN)

                              X11.1 – M34 unclamp Push Button (M34SW2)

M Codes for Clamp / Unclamp are – M 33 = Clamp

                                                         M 34 = Unclamp 

Note : Repeat the same if the alarm occurs in 5th axis.
