WARNING
This equipment operates at high voltages. Use extreme caution, observe all warnings,
and follow all safety procedures. Failure to observe safety precautions may result in
injury or death to personnel.
1. Open PLC enclosure.
2. Ensure PLC is ON, and check the power indicator LED (Figure 10, Item 7) on the Analog Output
Module. If the power indicator light is off, check the power indicator light on the Analog Input/Output
module adjacent. If the power indicator light on the adjacent module is ON, replace the Analog
Output module.
NOTE
If single sensors fail, test and replace the sensor as necessary IAW procedures given in
3. If the power indicator LED (Figure 10, Item 7) in ON, check for the following sensor failures:
If you see these sensor failures together:
Replace this Analog Input/Output Module
