Troubleshooting Operator Manual 129390199

9.2.6 Over Sterilize

Temperature

Occurs if chamber

temperature exceeds the

maximum sterilize

temperature (sterilize set

point temperature, plus the

10°F overtemperature

value).

Alarm Screen

Alarm Detail

Sterilize temperature is above

setpoint by more than

prescribed amount.

Causes And Correction:

1. Steam Pressure More

Than 50 Psig (3.4 bar)

• Check Steam Supply

Piping

2. Valve malfunction

•Repair V02

3. Control out of calibration

• Recalibrate (contact

qualified Service person)
