Operation

Theory of Operation

The design of the machine emphasizes performance reliability and long service life. The cylinder, shell, and main body panels are fabricated of stainless steel.

The machine uses one motor to drive the cylinder via a V-belt drive in all speeds.

A door-lock system prevents opening of the stainless steel door when water is in the machine. It also prevents operation of the machine when the door is open.

An electrically operated drain valve is used to retain the water and wash solution in the machine during the wash and fill steps.

The drain valve closes when power is applied and opens when power is removed, allowing the machine to drain in the event of a power failure.

The cylinder is designed with lifters or ribs that lift the garments from the wash solution when the cylinder rotates at slow speed and allow the garments to tumble back into the solution. The cylinder is perforated, allowing the water to pass through and drain from within during the wash process and extract.

Electrical controls for the machine are housed in a separate enclosure located underneath the top cover of the machine.

The machine uses an AC inverter drive control which provides four motor speeds using a single motor. The solid state output board converts motor logic from the V-computer to the correct signals for the AC inverter drive.

The AC inverter drive uses special balance detection software in conjunction with the V-computer to prevent out-of-balance conditions. When the AC drive detects an unbalanced load at the end of a drain step, the computer will make up to seven attempts to balance the load.

The operator can select from among 10 preprogrammed

cycles and program up to six for a total of 16 cycles available. A special permanent test cycle can be selected to verify proper operation of the machine.

V-Computer

The V-computer control is a programmable solid-state control capable of storing and running up to 16 cycles. A detailed description of these cycles can be found in the Programming section of this manual.

If this machine’s computer has been equipped with special preprogrammed cycles, a separate insert listing these cycles has been included in the resealable plastic bag which contained this manual.

Note: Never turn the power off while the computer mode switch is in the PROGRAM position. Such action will disorder portions of the programmed data, necessitating reprogramming of some or all of the existing cycles. Always return the mode switch to RUN position before turning the power off.
