Test the Analog Output Module
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 8, Item 7) on the Analog Output
Module.
3. If the power indicator light is off, check the power indicator light (Figure 8, Item 8) on the Analog
Input/Output module adjacent. If the power indicator light on the adjacent module is ON, replace the
Analog Output module.
4. If the power indicator LED (Figure 8, Item 7) in ON, check for power at the Actuator Valve No. 1
(Figure 9, Item 9). This can be confirmed by manually setting the actuator either fully open or fully
closed and operating the Water Treatment System. A correctly functioning Analog Output Module will
automatically correct the flow setting at the valve.
