BLBK AFTER 12 LOADS
SETTING FOR PUMP 1
The last blowback setting tells the controller how many loads on stations assigned to the selected pump must be completed before starting a blowback cycle.
After you define this setting, the controller returns to the Pump Settings menu screen.
Idle Delay Time Settings, Pump Settings Menu
After a station load is complete, the controller looks for a new demand on the system. If all stations are satisfied with material, the controller enters IDLE (No Activity) state. During this state, the atmospheric vent valve is open and vacuum vents. During IDLE (No Activity) state time, the controller monitors inputs looking for a demand on the system. Eventually, if no demand is on the system, the controller shuts down the pump(s) and waits for a demand signal. This process saves energy and prolongs the life of the vacuum pump.
The Idle time is the length of time in which the controller waits with no demand until the pump is turned off.
To set up the controller Idle Delay time, enter the Pump Settings menu, then:
•Press the MENU key until the Idle Delay Time prompt screen displays as follows:
IDLE DELAY TIME?
NO/YES
•Press the YES key to alter the Idle Delay time.
