PROBLEM

PROBABLE CAUSES & SOLUTIONS

Excessive liquid flowing out of vent to spit tank.

CAUSE A – Solenoid not closing.

Solutions:

•Check S3 solenoid wiring.

•Measure resistance across S3 solenoid. Value should read approximately 15Ω. If not, replace S3 solenoid.

•Inspect S3 solenoid for blockage. Refer to the Disassembly instructions in Maintenance.

•Lectro-Count CPU failure. Replace CPU board.

CAUSE B – Optical Sensor not functioning.

Solutions:

•Check optical sensor wiring.

•Measure resistance between the RED and WHITE wires. Value should be approximately 10kΩ. If not, replace optical sensor.

•Lectro-Count CPU failure. Replace CPU board.

No liquid flowing through meter during delivery.

CAUSE A – Liquid level not rising in optical air eliminator.

Solutions:

•Check S3 solenoid wiring.

•Measure resistance across S3 solenoid. Value should read approximately 15Ω. If not, replace S3 solenoid.

•Inspect S3 solenoid for blockage. Refer to the Disassembly instructions in Maintenance.

•Lectro-Count CPU failure. Replace CPU board.

CAUSE B – Meter outlet valve not opening.

Solutions:

•Check wiring of the outlet valve S1 solenoid.

•Measure resistance across S3 solenoid. Value should read approximately 15Ω. If not, replace S3 solenoid.

•Inspect S1 solenoid for blockage. Refer to the manual which accompanies the valve.

•Lectro-Count CPU failure. Replace CPU board.
