CONTROL SYSTEM

Design Features The Control System for AMSCO 400 Series Medium Steam Sterilizers monitors and controls all sterilizer operations and functions. The control system is factory-programmed with standard sterilizing cycles. Cycle values and operating features may be adjusted and verified prior to cycle operation.

Important: If cycle parameters (sterilize time, dry time, temperature) other than those listed are required, it is the responsibility of the healthcare facility to consult and follow the device manufacturer’s written instructions.

Once the cycle is started, cycle values cannot be changed until cycle completes.

Critical control system components are housed within a sealed compartment for protection from moisture and heat. A compartment cooling fan with filter is provided.

Operator interface control panel consists of a touch screen and impact printer located at sterilizer’s operating end (OE – loading or non-sterile side). If sterilizer is equipped with double doors, an additional touch screen is provided at sterilizer's non-operating (i.e., unload or sterile) end.

• Touch-Sensitive Screen features a multi-color, touch-screen graphics display. Sterilizer is operated by pressing touch-sensitive areas on display (touch pads). Appropriate touch pads, operator prompts and status messages necessary for sterilizer operation appear on display as needed. Display also indicates any alarm conditions either in or out of cycle.

• Ink-On-Paper Impact Printer, located near touch screen, provides an easy-to-read printed record of all pertinent cycle data on 2-1/4" wide paper. Printer take-up spool stores an entire roll of paper. Three paper tape rolls and two printer ribbons are furnished with each unit.

Non-Operating End (NOE) Control Panel (double-door sterilizers only) includes a touch screen similar to operating end, but without printer. Preprogrammed cycles can be started from NOE control panel. OE and NOE displays concurrently show identical information.

Cycle Configuration is accomplished at OE control Change Values menu. Cycle values and following operating parameters can be changed using Change Values:

• Time Display and Printout Units AM/PM or 24-hour notation.

• Access Code requires entry of a four-digit access code to change cycle values or change operating parameters.

• Audible Signals are adjustable. Touch pad and end-of-cycle signals can be adjusted to low, medium, high or off.

Alarm signal can be adjusted to low, medium or high; but cannot be turned off.

• Print Format allows selection of full or condensed cycle printout.

• Temperature Display and Printout Units are Fahrenheit (°F) or Celsius (°C). Temperature is set, displayed, controlled and printed to nearest 1°. Recalibration is not required when changing temperature units.

• Pressure/Vacuum Display and Printout Units in psig/InHg or bar. Recalibration is not required when changing pressure units.

SAFETY FEATURES

Control lockout switch prevents cycle from starting until limit switch signal is received. If signal is lost during cycle, alarm activates, cycle aborts and chamber safely vents controlled exhaust.

Chamber float switch activates alarm, aborts cycle and safely vents chamber if detecting excessive condensate.

Pressure relief valve releases pressure buildup in chamber if approaching or reaching rated pressure.

Power door safety feature causes door movement to stop if sliding door encounters an obstruction.

CONSTRUCTION

Shell Assembly Sterilizer vessel is formed from two fabricated Type 316L stainless-steel shells, welded one within the other. Type 316L stainless-steel end frame(s) is welded to the door end. On single door units, the back of the chamber is fitted with a welded 316L stainless-steel dished head.

Sterilizer vessel is ASME rated at 45 psig and insulated. Vessel includes one 1"-NPT chamber port for Customer use.

Steam-supply opening inside chamber is shielded by a stainless-steel baffle.

Chamber Door(s) Door is constructed of Type 316L stainless steel.

During operation, door is sealed by steam-activated door seal.

Door seal is constructed of long-life rubber compound. When cycle is complete, seal retracts (under vacuum) into a machined groove in end frame.

Long-life proximity switch detects if door is closed, or locking plates are engaged. An additional seal pressure switch prevents starting a cycle if door is not sealed.

Hinged-door sterilizer is equipped with a solenoid door lock.

Horizontal sliding-door units are provided with a mechanically-locking door assembly. Locking assemblies prevent door from opening as long as seal is intact, energized and chamber is pressurized at 2 psi or more.

The sterilizer door is fitted with a stainless-steel panel that insulates operator from chamber end frame, reducing chances of accidental contact with hot metal surfaces.

Chamber Drain System Drain system is designed to prevent sterilizer effluent from entering water-supply system and chamber. An automatic system of a stainless-steel plate-type condenser, converts chamber steam to condensate, disposing condensate to waste. Cooling water flow is regulated by waste line RTD, minimizing water usage. Water supply shut off valve is located in unit’s recessed area.

Vacuum System Vacuum pump reduces chamber pressure during prevacuum and post-drying phases. Following dry phase, chamber vacuum is relieved to atmospheric pressure by admitting air through a bacteria-retentive filter.

Steam Source Sterilizers are piped, valved and trapped to receive building-supplied steam at 50 to 80 psig, dynamic. Steam piping is brass and includes a shut-off valve, steam strainer and pressure regulator.

Piping All piping connections terminate within confines of sterilizer frame and are accessible from front, left side.

• Solenoid Valves with DIN connectors simplify sterilizer piping, and can be serviced individually.

• Manual Shut-off Valves are pressure rated at 125 psig (8.62 bar) for saturated steam. Valve handles are heat-insulated.

MOUNTING ARRANGEMENT

Sterilizers are arranged for either freestanding or recessed installation, as specified. Each sterilizer is height-adjustable.

Sterilizer subframe is equipped with a synthetic rubber gasket to provide a tight fit between cabinet panels on freestanding units, or between front cabinet panel and wall partition on recessed units.

On freestanding units, stainless-steel side panels and a louvered top panel enclose sterilizer body and piping.

ACCESSORY

Seismic Tie-Down Kit conforms to the California Code of Regulations.

Material Handling Accessories include stainless-steel chamber tracks and stainless-steel loading cars with painted-steel carriages. Stainless-steel chamber rack and shelf are available for 36" sterilizers. See TECH DATA SD978 for details.
