Simulator Operation and Program Transfer

Simulator Operation

The WE-6 simulator is an optional accessory to the WE-6 microcomputer-controlled UWP washer- extractor. See Figure 8. When the simulator is first energized, the simulator display will show the program (ROM) identification code for five seconds.

NOTE: Cycles for UWP machines are not compatible with cycles for UWPV machines. DO NOT transfer cycles from one of these models to another.

All programming instructions in this manual apply to the simulator as well.

The simulator is a hand-held unit which serves more than one purpose:

●The simulator’s primary purpose is to preprogram cycles for transfer to the washer- extractor and to transfer program cycles between the washer-extractor and the simulator in either direction.

●As an instructional aid, the simulator can be used for teaching programming techniques to individuals unfamiliar with the UWP WE-6 microcomputer.

The keypad and LED display are mounted on the top of the simulator. The ON/OFF rocker switch is located on the front end-panel.

The handle pivots to serve as a stand when using the simulator on a table. To pivot the handles, grasp them at the point of attachment to the main housing and gradually pull the handle sides outward until the ends disengage from the splined mounting holes. Pivot the handles to the desired position and release.

The simulator is battery powered and is supplied with an AC transformer which produces 12VDC at 500mA to recharge the battery pack from a 120V wall plug.

●The transformer is plugged into the power jack marked RECHARGE on the front end-panel of the simulator. The battery pack will be charged only while the simulator is turned on and is operating from the transformer.

●A fully charged battery pack will give about 3 hours of operation before recharging is necessary. Allow about 24 hours to fully recharge the battery pack with the transformer.

●The simulator battery pack contains NiCad batteries. These batteries will develop a “memory” according to length of time used. For example, if the simulator is habitually used for only one hour before recharging the batteries, the battery pack will eventually retain this habit and will power the simulator for only one hour before charging is required.

●When replacing the battery, use an exact NiCad replacement unit. Failure to do so will result in damage to the simulator.

The WE-6 simulator and the WE-6 microcomputer are capable of storing and running up to 39 cycles, each limited to 51 steps.

●The computer will not accept cycle numbers higher than 39.

●If an attempt is made to add a step to a cycle that already contains 51 steps, the computer will display “CYFULL” and refuse additional steps.

The front end-panel of the simulator holds the RECEIVE and TRANSMIT ports for the optic cables used in program transfers.

●When transferring cycles from simulator to computer or computer to simulator, the colored plugs on the ends of the optic cables must match the colors of the ports on the simulator and on the washer-extractor’s control module (gray to gray, blue to blue).

●If a mistake is made connecting the cables, the display will flash “CONN” and “ERROR” when the ENTER key is pressed during the last step of the cycle transfer process.

On the rear end-panel of the simulator are 6 toggle switches used to simulate various normal operations of the washer-extractor. These 6 switches simulate or control the PROGRAM/RUN modes, LOW LEVEL, MEDIUM LEVEL, HIGH LEVEL, DOOR OPEN/ DOOR CLOSED, and BALANCE.
