5.4 TECHNICAL DATASHEET ST04 - PRESSURE TRANSDUCER - SAFETY PRESSURE SWITCH
The autoclaves are equipped with the following devices, that are connected to the chamber:
- Pressure transducer
- Safety pressure switch
PRESSURE TRANSDUCER
The pressure transducer is connected to the chamber by a TEFLON tube; it detects internal pressure during the diffe-
rent cycle phase and sends an electric input to the general electronic card.
This input signal, combined with the temperature readings, ensures that the sterilization cycle is managed properly.
The transducer is installed at the side of the general electronic card and can be accessed after removing the right side
cover panel and, if necessary, the right upper cross member.
The pressure transducer is not serviceable; if it needs replacing, proceed as follows:
- Power off the autoclave from the main switch and disconnect the power cord.
- Remove the right external cover panel.
- Remove the protective cover of the general electronic card, which is held in place by 3 snap locks.
- Fully unscrew the locking ring nut of the TEFLON tube at the lower tting of the transducer and detach the tube from
the tting.
- Disconnect the transducer wiring from the general electronic card.
- Loosen the transducer retaining nut and slide the transducer off its support.
- Fit the new component in the seat in the support and secure with the retaining nut.
- Re-connect the transducer wiring to the general electronic card; the connector has a mounting position, be sure to
observe it.
- Trim off the end portion of the TEFLON tube so as to eliminate the portion of tube that had been sitting on the tting.
- Fit the Teon tube onto the tting and secure it in place with the locking ring nut. NOTE: Use great care when per-
forming this operation; to not overtighten or you will damage the tube.
SAFETY PRESSURE SWITCH
The safety pressure switch is connected through a TEFLON tube and disconnects power supply to the door closing
gearmotor when pressure inside the chamber is positive.
