ICTS-Problem after actual run
Since the day one when we have the actual run of the mooncake season, suddenly out of nothing all 6 sensors are started to giving problem of unreliabilities. Sensor 5 and sensor 6 almost out of order. Sensor 7 cannot detect at all. Sensor 1,2,3, and 4 cannot give stable green light signal most of the time. As such now only box motion Fuji machine is being used now.
Call OMRON to inform, and when he come to check, he even do not understand why these E3Z-D62 cannot operate properly as the settings for this application are OK already. As such he would go back and do some testing with other type of sensors and would only give his result by Wednesday 27/6/07.
Meanwhile, Keyence will come by tomorrow to show their sensor capabilities that will suit our application. The decision to use which sensor type and brand would only be make by Mr YU TT once both parties already shown their test result together with the right price later on.
On PLC panel box wiring, all wiring are completed already. It just a matter of program transfering from PC to PLC. However, for safety reason I'm not going to use it yet until the hardwires circuit and sensors are all OK to avoid unnecessary problem.

While waiting for sensors replacement, I upgrade the PLC ladder diagram so that later on, only 5 units of sensor required rather than 7 now. I eliminate the sensor 4 and sensor 6. Next I put back the emergency switch for better handling of the machine. Here is the new ladder.
