Heidelberg printing machine fault code daquan

(1) failure phenomenon, the machine can't run normally to print the album, and the front gauge control lever shows abnormality at the P port.

(2) Fault analysis: At first, the dust on the electric eye of the front watch was cleaned with a brush, but the fault still exists. When the electric eye of the front watch is blocked by hand or paper strip, it is found that the control lever on the transmission side is abnormal.

Turn off the main power supply and replace the plugs X 1 on the two RLl2 amplifiers under the feeder board. Restart the machine. After inspection, the gearbox side is normal, and the control lever on the operating side is abnormal. It is judged that the electric eye on the gearbox side is damaged.

(3) Solution: Turn off the power supply, unplug the X 1 plug on RLl2 at the transmitting side and print it on coated paper, and connect the wires 13 and 49, 14 and 50, 15 and 5 1 65438 to the electrical box/. After the machine is started, it can run normally.

2.Sm 102f failed to collect the paper pile.

(1) failure phenomenon, the machine can run, and the paper pile automatically drops after Feida feeds paper.

(2) Fault analysis shows that the down button and limit switch of Hangzhou main reactor are printed normally, and the induction switch of auxiliary reactor is normal. After careful inspection, it was found that the reactor height control amplifier 12B69 was unresponsive, and the red light of the amplifier 12B69 was always on. After re-adjustment, the self-adhesive was printed, and the fault remained. It is judged that the sensing block is damaged. press

(3) Solution: Open 12LVTl and unpack X2 Terminal Line 69. Disconnect 12B69 output signal to print Dongguan. After restarting, the delivery pile works normally.

3.CD 102-4 Bucket Water Level Detection Fault.

(1) failure phenomenon, CP window shows three groups of water level failures, and the machine cannot operate normally.

(2) Fault analysis and inspection of three groups of CD printers with normal water level in buckets. When the water level probe is removed and immersed in water, the fault remains unchanged, and the wiping water remains unchanged after removal.

Open the 3LVTl electric box under the three groups of worktops, and check whether the power supply voltage of the 3832 probe input to the printer is normal with an electric meter. When the probe is immersed in water and taken out, the outputs on terminal 32 of FEM64 and XF are unchanged. Zui finally judged that the water level detection probe was damaged.

(3) Solution: After turning off the main power supply, remove and seal the No.32 wire on the FEM64XE terminal board in the 3LVTl electric box, and connect the No.32 terminal on the FEM64XE terminal board in the 2LVT2 electric box with the No.32 terminal on the FEM64XE terminal board in the 3LVTI electric box with wires.

Send two sets of normal water level detection signals to three groups (or connect the power supply 1 terminal in 3LVT2 electric box with terminal 32 for printing, but it can't show that the water supply of the whole machine is normal), and the machine can run normally.

4.CDL 02-4 dampening system failure.

(1) failure phenomenon, insufficient alcohol concentration of fountain solution, unable to operate normally.

(2) Fault analysis: clean the intaglio printing water tank, circulation system, various filters, alcohol proportioning instrument, pipes, etc. as usual. Failure is still the same. After careful inspection, it is found that the solenoid valve of the alcohol control loop has sound absorption, the system loop is unobstructed, and the water pressure is normal, but it does not absorb alcohol.

The system adopts the siphon principle, and the negative pressure generated by the fountain solution circulation is sucked into the alcohol printer, but the fountain solution circulation is large, so it is suspected that there is no negative pressure.

(3) Solution: Open the alcohol proportioning instrument and check it carefully. It was found that the O-ring seals at both ends of the solenoid valve copper block were damaged and leaked. Shanghai printing recruitment, replacement, troubleshooting after startup.

Extended data:

Matters needing attention in handling:

1, insist on cleaning the circulating system frequently, and ensure that the pipeline is unblocked and well sealed.

2. Use qualified fountain solution and purified water for circulating water.

3, check the provisions of the Ningbo printing plant printed matter, and timely adjust the delivery of paper.

4. Buy the front gauge electric eye in time and replace it.

5. Observe the paper pile frequently and adjust the height of the paper pile in time.

6. Always check the water level of three groups of buckets.

7. Buy water level probes in time and replace them. Packaging and printing.
