Self-Diagnostic Check

The Validator Sterilizer will perform a self-diagnostic test on 8 key components. Start the test by depressing and holding the START/CLEAR switch while you depress, then release the POWER switch. The sterilizer will beep once, indicating the beginning of the self-diagnostic procedure. Use the table below for description of tests.

Sequence Number Display Checked Components Verifying Operational Function
1 GO/NO Pressure Sensor On Temperature PCB Continuity*
2 GO/NO Steam Sensor Continuity* Oem Units Will Fail If Temperature at Sensor Is Colder Than 20 degrees centigrade. Allow Sterilizer To Warm-Up and Repeat Test
3 GO/NO Surface Continuity*
4 Blue Window Display of kPA/C/Min Seven Segment Display Is Checked
5 Panel LEDs Cycle and Program/Power Indicator Lights Illumination Of Indicator Lights
6 GO/NO Vent Solenoid Vent Solenoid Operation and Continuity*. (Displays GO Even If Solenoid Sticks Check That Plunger Activiates)
7 GO/NO Fill Solenoid Fill Solenoid Operation and Continuity*.(Displays GO Even If Solenoid Sticks Check That Plunger Activiates)
8 GO/NO Dump Solenoid Dump Solenoid Operation and Continuity*.(Displays GO Even If Solenoid Sticks Check That Plunger Activiates)
*Continutity Definition: An Electrical Test For Determining Whether An Electrical Connection Is Broken.

To test, (with the unit unplugged) set your volt/ohm meter on ohms Ω Place a lead on each of the contact points. If the needle on an analog meter doesn't move (stays to the left), component is bad and replacment is required. If it approaches zero, component is good. On a digital meter, if the read out is "1" component is bad. If approaching zero, component is good.
