2.WASH: System goes through cycles to clean and dry dirty ionizing-collecting cells

3.RESET: Returns the system to the NORMAL mode if a WASH cycle is accidentally initiated

4.SLEEP: Waiting period after a WASH mode

Washing

Power Play’s PLC control is preprogrammed to manually initiate and cycle through the wash, rinse, dry and system standby steps, as described below. To initiate a wash manually, with the system in the NORMAL mode, depress the WASH push-button. The WASH mode consists of 6 steps. FIGURE 6 describes the indicating light and system component status while operating in the WASH mode. After the WASH/FAN DRY cycle is completed, the system is programmed to shut down and manual start next morning. As indicated in FIGURE 6, there is a 5 minute delay period, after wash initiation, before the wash process begins. If the WASH cycle is accidentally initiated, the operator may reset the system during the 5 minute delay period, and the system will return to NORMAL operation. If the system is reset after the 5 minute delay period, the WASH cycle will be accelerated and the system will return to the NORMAL mode after the WASH cycle is complete.

During operation in the WASH mode, depressing the EMERGENCY STOP button will immediately shut down the system. The red light adjacent to the EMERGENCY STOP button will illuminate until the button is released. The system will continue to operate in the WASH mode after the EMERGENCY STOP button is released.

Reset Mode

On rare occasions, it may be necessary to reset the system. This may be required if a WASH cycle is inadvertently initiated. As indicated previously in FIGURE 6, there is a 5 minute delay period after the WASH button is pushed, before the wash process begins. If the WASH cycle is accidentally initiated, the operator may reset the system during the 5 minute delay period, and the system will return to NORMAL operation. If the system is reset after the 5 minute delay period, the WASH cycle will be accelerated and the system will return to the NORMAL mode after the WASH cycle is complete.

FIGURE 7 on page 10 illustrates the sequence of events that occurs when the system is reset during the different stages of system operation. When the system is in the RESET mode, the white RESET light will illuminate on the control panel. It is recommended that the system be programmed so that system on/ off and wash cycles are automatically initiated. This programming will be done by the factory engineer during commissioning.
