3VWWZ036CD001 | GE | Voltage input terminal

The voltage input 3VWWZ036CD001  is generally designed with a long-term uninterrupted working system for various types of PLC control cabinets. However, there are occasional places where actions need to be modified, and it is important to quickly find the location and modify them. Modifying actions that occur outside the PLC control cabinet takes a lot of time.
1. Is the PWR (power) light on? If it does not light up, check the power supply voltage at the voltage input terminal (98-162VAC or 195-252VAC) of the frame using an AC power supply; For frameworks that require DC voltage, measure the DC voltage between the+24VDC and 0VDC terminals. If it is not a suitable AC or DC power source, the problem occurs outside of the SRPLC. If the AC or DC power supply voltage is normal but the 3VWWZ036CD001  light is not on, check the fuse, and if necessary, replace the CPU frame.
2. Is the PWR (power) light on? If it is on, check the displayed error code, refer to the code definition in the error code table, and make corresponding corrections.
3. Is the RUN light on? If it doesn’t light up, check if the programmer is in the PRG or LOAD position, or if there is a program error. If the RUN light is not on and the programmer is not plugged in, or if the programmer is in RUN mode and no error code is displayed, the CPU module needs to be replaced.
4. Is the 3VWWZ036CD001  light on? If it is on, the lithium battery needs to be replaced. Due to the fact that the BATT light is only an alarm signal, even if the battery voltage is too low, the program may not have changed yet. After replacing the battery, check the program or have the PLC control cabinet test run. If there is an error in the program, after completing system programming initialization, reinstall the program recorded on the magnetic tape into the PLC control cabinet.
5. In a multi frame system, if the CPU is working, the RUN relay can be used to check the operation of several other power supplies. If the RUN relay is not closed (high resistance state), follow the first step mentioned above to check the AC or DC power supply. If the AC or DC power supply is normal and the relay is disconnected, the frame needs to be replaced.
