Check Operation of Flosep Rinse Water Solenoid Valve

Verify that the output S2:DO.8 OR .9 is energized. Yellow output light on? If Yes, then check for voltage with meter at output terminal.

• Yes
• No
• N / A

Measure the voltage across the output terminal (Positive: lead to output card terminal S2:DO.8 OR .9; Negative: lead ground/0v-).

Expected reading is approximately 24 VDC when the output is ON.

Meter name

Measure voltage across the relay coil terminals. Check voltage between terminals/wires 2027-2 and 2028-2 and 20-2011 0v- on CR2027-1,CR2027-2.

Expected reading is approximately 24 VDC when the PLC output is ON. You can also manually make the Orange flag on face of relay to manual engage. Flip flag up to seal on.

Meter name

Listen for a click when the relay energizes.

• Yes
• No
• N / A

If there is no voltage or no click, perform the following checks:

• Check the PLC output wiring

• Measure coil resistance

• Replace the relay if faulty

Measure the voltage at the solenoid terminals/ cable terminations at condulet.

Expected reading is approximately 24 VDC when the relay is energized.

Meter name

If voltage is present but the solenoid doesn’t actuate, perform the following checks:

• Measure coil resistance

• Check for mechanical seizure

• Replace the solenoid if needed

• Check Electrical Connections

Inspect for the following issues:

• Wiring damage

• Corrosion

• Loose connections

Confirm 24 V feed to relay contact common: 1809-1.

• Yes
• No
• N / A

Confirm 0V common: 16-1616. Ohm to Ground. Resistance<20ohms.<

• Yes
• No
• N / A

• Yes
• No
• N / A
