4.24 Pressure / Temperature Potentiometers Adjustments

EQUIPMENT ALERT

The pressure zero, pressure range, and

temperature potentiometers cannot be adjusted separately. If one potentiometer needs adjusted, then the entire potentiometer adjustment procedure must be performed, and it must be performed in the proper sequence as follows:

(1 ) Remove right hand side panel. (2 ) Open sterilizer door.

DANGER

The following steps require the steril-

izer to be plugged in to power while the adjustment is being performed. Do not touch any components except for the adjusting screw of the potentiometer. Failure to comply with these instructions could result in an electrical shock, which could result in severe personal injury or death.

NOTE

After the following step is performed, the display PC board lamps will individually illuminate and then extinguish one at a time in a left to right sequence. When all the lamps have illuminated and extinguished, proceed with step 4.

(3 ) Press and hold down the LIQUIDS and PACKS

buttons simultaneously while connecting the power cord to the sterilizer (See Figure 4-27). Release the LIQUIDS and PACKS buttons.

NOTE

When each button is pressed, its corresponding lamp will illuminate and stay illuminated. Also, after the following step, the PRESSURE (PSI) display will display the pressure that the control PC board is reading and the TEMP (°F) / TIME (MIN: SECONDS) display will display the temperature that the control PC board is reading. When each button has been pushed, proceed with step 5.
