Pro Series LCD / Pro Touch Error Codes

The inner chamber temperature sensor has reported a reading outside the safe operating range. This error has two variants: - Over-temperature: The inner chamber temperature has exceeded the maximum safe limit. This condition is monitored continuously once a cycle is active. - Under-temperature: During a pressurized phase of the cycle, the inner chamber temperature has fallen below the minimum expected level. This variant is only active after the system reaches operating pressure.

After the vacuum pump has completed its pull-down cycle, the system tests the vacuum level. If the chamber pressure is above the expected vacuum level, the system determines that a leak exists and the vacuum integrity is compromised.

During the sterilization holding phase of a standard-temperature cycle, the chamber pressure has exceeded the maximum allowable limit. This indicates that more steam is present in the chamber than expected for the set sterilization temperature.

During the sterilization holding phase of a high-temperature cycle, the chamber pressure has dropped below the minimum required level. This indicates insufficient steam pressure to maintain the target sterilization conditions.

During the sterilization holding phase of a standard-temperature cycle, the chamber pressure has dropped below the minimum required level. The cause and implications are similar to Error 4 but apply to the lower operating pressure of standard-temperature cycles.

During the initial preheat phase of the first purge cycle, the drum temperature has failed to reach the minimum warm-up threshold within the allowed time. This indicates that the drum heater is not functioning or is heating too slowly.

The steam generator temperature sensor has reported a reading outside the safe operating range. This error has two variants: - Over-temperature: The steam generator temperature has exceeded its maximum safe limit. This can indicate a dry-fire condition (no water in the steam generator) or a stuck heater relay. - Under-temperature: During a pressurized phase of the cycle, the steam generator temperature has fallen below the minimum expected level.

During the purging or heating phase, the system has detected that the chamber pressure is not increasing despite repeated pump and injection cycles. The system counts consecutive attempts where the pressure fails to rise by the expected increment. After a sustained number of failed attempts, it concludes that pressure cannot be built and triggers this error.

The drum temperature sensor has reported a reading outside the safe operating range. This error has two variants: - Over-temperature: The drum temperature has exceeded its maximum safe limit. - Under-temperature: During a pressurized phase of the cycle, the drum temperature has fallen below the minimum expected level.

The chamber pressure has exceeded the critical safety limit. This is the highest-priority pressure-related error and represents a potentially dangerous condition. The system triggers an immediate safety shutdown to protect the operator and the equipment.

During the initial preheat phase of the first purge cycle, the steam generator temperature has failed to reach the minimum warm-up threshold within the allowed time. This indicates that the steam generator heater is not functioning or is heating too slowly.

At the transition point from the purging phase to the heating phase, the inner chamber temperature is below the minimum expected level. This indicates that the purging phase did not adequately preheat the chamber, which could lead to extended heating times or cycle failure.
