Troubleshooting The Gen III+

Cause:

The insecticide bottle is empty and must be replaced. Follow the instructions in Step 7, Install Insecticide and Program Dose Settings in Gen III+ QuickStart Guide

Potential Causes:

• System Mode is set to OFF or ON and should be set to AUTO-EVERYDAY or AUTO-CUSTOM. See Gen III+ QuickStart Guide.

• No AUTO MIST cycles defined. See Gen III+ QuickStart Guide.

• Unit expecting input from wind sensor, but no wind sensor is installed. Set SEN to OFF. See Step 8h, in Gen III+ QuickStart Guide

Potential Causes:

• System Mode is set to OFF. Reset System Mode to an AUTO mode or ON. See Gen III+ QuickStart Guide.

• Remote mist duration is set to OFF. See Gen III+ QuickStart Guide.

• Unit does not recognize remote transmitter. See Orient the Remote Transmitter in Gen III+ QuickStart Guide.

• Remote antenna not installed. See Gen III+ QuickStart Guide.

• Dead batteries in remote transmitter. Replace batteries and retry.

• Other signals are interfering with reception. Change DIP switches in remote transmitter See Section 4 in the Operations Manual.

• Remote transmitter or receiver has failed. Replace.

Cause:

NOZzle count in SET-UP Menu not set. See Section 3, Setting Up the Unit.

Confirm the current position of the float switch

• MAINTENANCE Menu, FLT

• “dn” indicates float switch is down. “UP” indicates float is up.

Confirm the float switch is working

• Remove controller from cavity so you can access float in batch tank.

• MAINTENANCE Menu, FLT

• With your hand, push the float down. Controller should display “dn.”

• MAINTENANCE Menu, FL tst
• Press Green Enter button for 3 seconds. Unit will open inlet valve and water will flow for 6 seconds.
• FL ### (in ml) will be displayed. Press Green Enter Button
• One of four results displayed:
  
  

  • OK: flow is normal and flowmeter is OK

  • Low: flow is low and flowmeter OK

  • High: flow is higher than normal and flowmeter OK

  • Fail: flow meter not working

Most Common Cause

• The dosing pump that pumps insecticide out of the bottle and into the mixing tank requires maintenance or has failed.

Other Potential Causes

• During the routine to virtually REFILL the bottle, the bottle size or level was improperly set.

Diagnostic Steps

• Remove fasteners securing controller to black plastic shroud. Lift the controller to a position where you can observe the clear tubing on the right side of the dosing pump. Navigate to the MAINTENANCE Menu and run a manual charge (CHG). If the dosing pump is working, you will observe a pulsing flow of insecticide in the clear tubing.
  If there is no flow, replace the duckbill valves in the pump head.

Most Common Cause

• Float is stuck in down position due to buildup of residue on post that hinders travel up during refill and down during misting.

• During the FILL routine, water will run out of the unit until the controller recognizes the issue and closes the inlet solenoid valve.

Other Potential Causes

• Inlet Solenoid Valve: jammed in open position

• Flow Meter: cracked

• Batch Tank: Leak caused by hole or tear. Water will run out of the unit.

Diagnostic Steps

• Turn off power to the unit. If water continues to run out of the unit, the inlet solenoid valve is stuck in the open position. Remove valve, disassemble and clean, then replace.

• If turning off power stops the flow of water, the issue is with a stuck float switch, a cracked flow meter or leaky batch tank.

• Run Float Switch Diagnostic (See Topic 6 Above) to ensure float switch is working.

• If float switch is working properly, remove controller and shroud and observe flowmeter for cracks and batch tank for leaks.

Most Common Cause

Float is stuck in up position due to buildup of residue on post that hinders travel up during refill and down during misting.

Other Potential Causes

• Nozzle circuit too small (less than 10 nozzles) and/or mist duration too short to reliably drop the level in the batch tank in each mist. Turn off the ERR0 switch in the SET-UP menu

• Agitation Valve: 1) stuck in the closed position (due to swollen seal), 2) inadequate voltage to open, 3) controller relay failure

• Pump: 1) intake filter completely clogged, 2) poor connection of pump intake line, 3) pump failure

• Motor: 1) power issue, 2) controller relay failure, 3) motor failure
  Auto Drain Valve: no longer attached to bypass line in batch tank.

Diagnostic Steps

• Run Float Switch Diagnostic (See Topic 6 Above) to ensure float switch is working.

• Run manual mist and observe the following:

  • Listen for the motor. If no motor sound, problem is motor or power to it. Further diagnostics required.

  • Listen for agitation valve to click, observe pressure gauge, and observe mist volume during MIST routine.

    • If pressure is 240 psi and mist pattern is OK, problem is stuck float switch. Clean switch and post.

    • If no agitation click and/or pressure <50 psi with no mist, problem is with agitation valve. Further diagnostics required.

    • If agitation valve clicks, and pressure <50 psi with no mist, problem is with pump or auto drain valve. Ensure auto drain valve is attached to bypass and intake filter is clean, and pump intake well connected. Otherwise, probable pump failure.

Most Common Cause:

• Clogged pump intake filter reduces flow through the pump and nozzle circuit and will eventually result in pump failure.

Other Potential Causes

• System Setup does not reflect installed system – 1) fewer nozzles installed than entered, 2) actual nozzle flow rate is much less than estimated nozzle flow rate in the controller 3) the tolerance in the error calculation is too small. Disable ERR2.

• Nozzle Circuit: 1) nozzle tips are clogged, 2) nozzle circuit tubing is blocked or kinked

• Flowmeter: 1) not working properly, 2) flow of water from the faucet too low for flowmeter to work properly

Diagnostic Steps

• Confirm system setup: nozzle count (NOZ in SETUP Menu) equals nozzles installed, nozzle flow rate (NFR in DATA Menu) is reasonable (35 – 50 ml/min) and tolerance (TOL in DATA Menu) is 75% or greater.

• Run Flowmeter Diagnostic (See Topic 7 Above) to confirm adequate water flow to unit and that flowmeter is working properly.

• Run manual mist and observe the pressure gauge and mist volume:

  • If pressure gauge is oscillating, intake filter is clogged. Clean filter (and float switch).

  • If pressure is 240 psi, but mist volume is small, tips are clogged or nozzle circuit is partially blocked. Clean or replace tips and/or locate blockage

Most Common Cause:

• Leak in nozzle circuit.

Other Potential Causes

• System Setup does not reflect installed system

  • more nozzles installed than entered,
  • actual nozzle flow rate is much greater than estimated nozzle flow rate in the controller
  • the tolerance in the error calculation is too small.

• Flowmeter: 1) not working properly, 2) flow of water from the faucet too high or turbulent for flowmeter to work properly

Diagnostic Steps

• Confirm system setup: nozzle count (NOZ in SETUP Menu) equals nozzles installed, nozzle flow rate (NFR in DATA Menu) is reasonable (35 – 50 ml/min) and tolerance (TOL in DATA Menu) is 75% or greater.

• Run Flowmeter Diagnostic (See Topic 7 Above) to confirm adequate water flow to unit and that flowmeter is working properly.

• Look for leaks in the nozzle circuit.

• Note about Slow/Small Leaks: During the hours between mists, fluid can leak out of a fitting, that is potentially buried underground, and drain the nozzle circuit. The next time the unit mists, the nozzle circuit must be refilled completely and this may be a large enough additional volume to cause ERR3. Small leaks are notoriously difficult to troubleshoot because it takes an extended period for the nozzle circuit to drain and cause ERR3 to be displayed. That is, the error condition does not occur while the user is on site troubleshooting the issue.

Most Common Cause

• Faucet supplying water to the unit has been shut off.

• Note: if faucet is shut off - causing ERR4 - and then turned back on, Gen III+ will automatically clear the error and resume normal operation during the next scheduled mist.

Other Potential Causes

• Float Switch: stuck in down position. During the FILL routine, water will run out of the unit until the controller recognizes the issue and closes the inlet solenoid valve.

• Flow Regulator: clogged, reducing flow to batch tank

• Water Supply: 1) inadequate flow, 2) inlet water filter is clogged.

• Batch Tank: Leak caused by hole or tear. Water will run out of the unit.

Diagnostic Steps

• Ensure faucet supplying water to unit turned on.

• Run Float Switch Diagnostic (See Topic 6 Above) to ensure float switch is working.

• Run Flowmeter Diagnostic (See Topic 7 Above) to confirm adequate water flow to unit and that flowmeter is working properly. Clean inlet water filter.

• If water is running out of unit, problem is float switch or leak in batch tank. Clean float switch (and intake filter). Otherwise, look for leaks in batch tank.

Most Common Cause

• Float is stuck in down position due to buildup of residue on post that hinders travel up during refill and down during misting.

• During the FILL routine, water will run out of the unit until the controller recognizes the issue and closes the inlet solenoid valve.

Other Potential Causes

• Flowmeter: 1) not working properly, 2) flow of water from the faucet too high or turbulent for flowmeter to work properly

• Batch Tank: Leak caused by hole or tear. Water will run out of the unit.

Diagnostic Steps

• Ensure faucet supplying water to unit turned on.

• Run Float Switch Diagnostic (See Topic 6 Above) to ensure float switch is working

• Run Flowmeter Diagnostic (See Topic 7 Above) to confirm adequate water flow to unit and that flowmeter is working properly.

• If water is running out of unit, problem is float switch or leak in Batch Tank. Clean float switch (and intake filter). Otherwise, look for leaks in batch tank.

Most Common Cause

• Flowmeter is either clogged or has failed.

Diagnostic Steps

• Run flowmeter test. (Section 7, Troubleshooting) to confirm adequate water flow to unit and that flowmeter is working properly.

• If not, remove flowmeter and clear sediment and replace. Run flowmeter test again. If it fails, replace.

• Note: Ensure inlet water filter is installed and clean.
