Manually rise and fall is not working properly receiving table
Date:2004-08-05

1) manual rise and manually drop does not work

Reasons for this failure:

Automatically switch Q12 (225) / Q7 (425) trip contactor K12/K13 (225) K5/K6 (425) action, but no 380V power supply to the motor.

Contactor K12/K13 (225) K5/K6 (425) control the power cord loose, contactor K12/K13 (225) K5/K6 (425) does not work.

Loose PLC output end of the common power supply line, the PLC output of output directions, but there is no power output, contactor K12/K13 (225) K5/K6 (425) does not move.

The up / down buttons M51/M52 public 100 line loose, leading PLC acquisition.

Manually rise and fall is not working properly receiving table.

2) manually rose normal, manual down does not work.

Contactor K13 (225) / K7 (425) fault or the corresponding coil control line failure, resulting in the contactor no action.

The PLC internal output relay damage, leading to the PLC output point does not have a power output contactor no action.

Lower limit switch action or damage, or improper position adjustment (cardboard collection location normal but switching operation) lead to the PLC dropped in the end, not the receiving table down operation has been detected.

Manually rise and fall is not working properly receiving table.

3) the manual down normal, manually increase does not work.

Contactor K12 (225) / K6 (425) fault or the corresponding coil control line failure, resulting in the contactor no action.

The PLC internal output relay damage, leading to the PLC output point does not have a power output contactor no action.

Limit switch action or damage, or improper position adjustment (cardboard collection location normal switching action) causes the PLC has been detected to the closing paper on stage to rise to the top-up operation can not be carried out.

The paper detection switch action or damage, resulting in the PLC detects that the paper has reached the highest position, up operation can not be carried out.
