SECTION 4: SERVICE PROCEDURES

WATER LEVEL CONTROL (AS USED ON AN APRB)

WATER LEVEL CONTROL: The water control is used on this machine in conjunction with a sensing probe, to detect the water level in the rinse tank, and to control the automatic refilling of it.

When the water level decreases as the rinse pump starts to push water through the rinse tubes, the probe then sends a signal to the control which deactivates the plug-in relay (located on the control circuit board). When the relay deactivates, its contacts return to a normally closed position. The solenoid valve is connected in series with these contacts and at this time energizes to allow water to refill the rinse tank to the proper level. Then the relay activates and opens the normally closed contacts to deactivate the solenoid valve.

SYMPTOMS OF LEVEL CONTROL FAILURE:

1.Water level in rinse tank is not maintained, indicated by diminishing rinse spray halfway through its cycle.

2.Water continues to run at the end of the rinse cycle or water continues to spray out of the rinse tubes.

PROCEED WITH CHECKOUT

1.Remove power to machine by turning circuit breaker to its “off” position.

2.Remove 4 screws holding control panel on control box. Remove panel and attach to one side of control box with 2 screws.

3.Locate water level control board and disconnect wires going to terminals marked C & H. Mark and insulated wires for cor- rect placement.

4.Re-apply power to machine. With an insulated jumper wire, touch jumper between terminals C & H, relay in clear plastic cube should activate as wire touched to terminals, observe relay contacts, they should pull in.

5.If relay operates, the control can be deemed operational and other causes should be explored. EXAMPLE: Solenoid valve not functioning properly, loose or broken wires in circuit, sensing probe malfunctioning, or loose green ground wire.

6.If relay does not operate, replace control.

7.Remove sensing probe from rinse tank and clean any deposits that may have built up causing it to malfunction.

8.If solenoid valve does not open or remains open, see instructions on separate page to check, clean or repair.

9.Remove power to machine and replace wires that were removed in above steps.
