At the end of a step, (after the drain but before the start of the next step) the retort
temperature is not at the value required by the program. This check is done only at
the end of a stand-by step because it is not possible to know how much time is
necessary for the reagent to reach the correct temperature. The time is strictly
related to other parameters, such as: required temperature, ambient temperature,
type and quantity of reagent, quantity of samples in the retort, etc.
This is a non-blocking alarm because reagent heating is not critical for obtaining
good results. If the alarm involves the Retort heating system, the instrument will
possibly be blocked during the first paraffin step. The process is not ended but the
samples will be left in paraffin with little or no damage as compared to being in other
reagents for a long period of time.
This alarm may frequently appear during very short steps, in this case is not a
problem because it is normal that the retort temperature will not reach the set point
temperature during very short steps.
Cause – Incorrect working or damage of: temperature sensor, heating
resistance, safety thermostat.
Solution – No intervention by the user is possible. If the problem persists,
contact TBS

for technical assistance.

The duration of the drain was too short.
Cause – Insufficient level of reagent in the indicated bottle.
Solution – Verify reagent levels on level surface, not mounted in unit. If this
occurs during the alcohol step of the Purge Cycle, reduce the percentage of
alcohol from 100% to 80%, but maintain the volume at the normal level.
4 - P / V T I M E O U T
Occurs if the instrument is unable to create processing pressure or vacuum in the
Retort at the scheduled time. The processor will not try to create pressure or
vacuum in that step and will go on with the program. During the next step, if
scheduled, it will try again.
Cause – Pump failure, lid gasket leakage.
Solution – Check and clean the lid gasket.

Excessive level of reagent in the Retort during the fill; the overfill is recognized (by
the sensor “S” or by the pressure gradient “P”) and the filling is stopped before it can
produce a failure. The process can continue without problems.
