Section 2 GENERAL SYSTEM DESCRIPTION
2.1 MODEL COVERED
This manual covers the SW-4600 SERIES washer, which has been designed to provide a fully
automatic programmed cycle for the processing of laboratory glassware and utensils. It is
available in the following cabinet configurations.
Type I: Single door, freestanding unit
Type II:Single door, Recessed on wall installation
Type III:Two door, Pass Thru, free standing, recessed one end or recessed two ends
All Scientek washers utilize a Micro-processor Control Unit (MCU) which has been designed to
provide ten pre-programmed timed cycles of washing, rinsing and drying.
The wash chamber can accommodate loads of up to 27" inches high, 26" wide and 26" in depth.
The SW-4600 has a full size glass door. Every washer comes standard with a multi-level, multi-
spray arm adjustable loading rack. The loading rack has a maximum of four levels to
accommodate 4" deep baskets. Each loading shelf can be removed to accommodate larger loads.
The washer comes equipped with blanking plates to divert water flow when any one of the four
levels is not in use. Scientek offers a stainless steel transfer cart with a lower support shelf, as
an option, to store and transport additional loading racks.
Washers are equipped with a 3.0 HP motor and stainless steel pump. The pump is pressure-
rated for 110 GPM at 68 foot head pressure. Water treatment is delivered to the processing load
through a 1-1/2 inch stainless steel circulatory piping system that provides a high impingement
pressure on both the interior and exterior surfaces of the load. As each processed load is treated,
the circulating water is filtered by two separate debris screens to remove suspended particles
and to prevent paper or foreign matter reaching the pump impeller.

Section 5 OPERATION THEORY
5.1 POWER "ON" CONDITION
The washer is turned on by turning power switch to ON position. The switch illuminates, and the
drain valve closes automatically.
5.2 WASH CYCLE START-UP OPERATION
Pressing the START button on the panel display signals the microprocessor to begin a
programmed wash cycle. The microprocessor proceeds logically depending on the settings of the
various program parameters for a selected cycle..
5.3 STOP BUTTON OPERATION
The operation of the washer is halted when the STOP button is depressed. This condition is
indicated by a message on the operator interface and STOP light on the clean side control panel..
5.4 WATER LEVEL SWITCH OPERATION
The liquid level switch monitors the level of water in the sump. If the sump is not full, then the
microprocessor signals the water-fill solenoid to open, allowing fresh water to enter the wash
chamber. When a full condition is reached, the microprocessor proceeds to the next step of the
programmed wash cycle.
Timed fill delay option is available to compensate for the volume of water in re-circulating piping
and various headers.

5-2
5.5 WASH CHAMBER "FILL" OPERATION
Before the fill solenoid is opened, the microprocessor checks the signal from liquid level switch.
If the signal is not present, then the microprocessor signals the fill solenoid to open. This allows
fresh water to enter and fill the sump. Once the tank is full, the fill solenoid is closed.
5.6 DETERGENT MODE OPERATION
Washers are programmed to automatically inject detergent at the start of wash cycle, a pre-set
value of 15 seconds for each cycle is standard and can be adjusted at user end.
Refer to the AVAILABLE OPTIONS section in this manual for complete listing and description
of the various detergent dispensing systems available.
5.7 EXTENDED WASH TIMER OPERATION
Refer to section 6.4.1.1 ‘Cycle time settings’ to adjust wash and rinse times in each individual
cycle, if you do not find the suitable times that are pre-set in the ten-cycle selection.
5.8 SUMP HEATER OPERATION
The sump heater can be specified to be electric or steam. The operation is controlled by the
microprocessor, and the liquid level switch. Only when the signal from liquid level switch
indicates full sump, the sump heater operate. This safety feature ensures that an over-heat dry
condition never occurs.
5.9 DRAINAGE
The programmed wash cycles include a specially designed three-sequence drain system. After
each washing and rinsing, water is drained in the following manner: power drain, gravity drain,
and flush drain.
Power drain activates the pump motor, and forces the water to drain quickly. Gravity drain de-
activates the pump motor, and allows the water to drain by gravity. Flush drain allows fresh
water to enter the wash chamber as the drain valve remains open for several seconds. This step
serves to flush out and rinse away any detergent residue at the bottom of the sump.

5-3
5.10 FINAL RINSE OPERATION
Final rinse can use D.I. water or tap water. The milk lube can be injected if required. This will be
pre-programmed by the factory and can be altered to suit the facility.
5.11 POWER "OFF" CONDITION
To turn washer OFF, switch power switch to “OFF”, green light will go off. The drain valve
automatically opens to allow the sump to completely drain by gravity.
5.12 "IDLE" STATE CONDITION
The "idle" state condition describes the washer when it is in-between loads. After a wash cycle
has completed, and the next one has not yet begun, the only illumination on the display panel is
“Ready to Wash”, select cycle and press start button.
5.13 MICROPROCESSOR CONTROL SYSTEM
The Microprocessor Control System is based on an Allen Bradley Micrologix 1500 series
microprocessor controller.
The Allen Bradley microprocessor controller is an industrial grade controller that has proven its
dependability, durability and performance primarily in heavy industrial environments such as
pulp and paper mills, mining operations, and industrial plants for such functions as machine tools,
material handling, assembly machines, robotics, and energy management.
The heart of the system is the “Smart Control” operator interface. This is an Allen Bradley
PanelView 600 color touch screen interface, programmed with user display functions for
complete information feedback during all ten cycles.
Unit will also provide diagnostic and service functions for testing PLC inputs and outputs.
