The issue of DCS DI input points not releasing electricity
Thread Content
Our factory uses the ECS-100 system from Zhejiang University, and the problem we are facing now is that the operation feedback signals from the pumps and motors are abnormal. Turn the device on, then turn it off. The operating status kept showing as \"on\"; after unplugging the relay and replugging it, it showed \"off\" and everything worked normally. It still shows as running after being turned off next time. The accompanying terminal block is for 220V. How to solve this problem?
It’s best to seek help from Zhejiang University’s after-sales service to resolve the issue!
Interference? 220V AC interference
There are two possibilities: either there is interference in the vicinity, or the relay needs to be replaced
Is the cable shielded? Is the shielding properly grounded?
Check the TB366-GPRU manual. I think there’s a problem with the wiring.
