Siemens PLC - Setting Parameters
Each Vmax system is tested and checked at the factory prior to shipment to ensure trouble-free operation. In the unlikely event you encounter a problem, we recommend that you consult with your local distributor for parts/service. Remember, when calling for service, parts or system information, always have the pump or system model number and serial number ready.

DEKKER uses the Siemens LOGO! programmable logic controller to perform several functions, such as turning pumps on and off based on feedback from a vacuum transducer, alternating the lead/lag pumps in a multiplex vacuum system, or providing minimum run time to protect pump motors from frequent starts (10-minute minimum run time is typical).
When the system is running, the normal screen should be the Value screen.
Press the Down arrow to get to the Date/Time screen.
From the Date/Time screen, open the Menu screen by pressing the ESC button.
Use the Down arrow to point to Set Param then press the OK button.
Typical block assignments for a duplex system will be:
B15 = Lead Pump
B16 = Lag Pump
B17 = Alternation Day/Time
B14 = Lag Pump Alarm Settings (Available on NFPA 99 systems for medical applications)
Typical block assignments for a triplex system will be:
B15 = Lead Pump
B16 = Mid Pump
B23 = Lag Pump
B17 = Alternation Day/Time (Available on NFPA 99 systems for medical applications)
B14 = Lag Pump Alarm Settings
To change a parameter value, use the Up/Down arrows to show the block that you want to modify, then press the OK button. You can change the value by moving the cursor to the desired location with the Left or Right arrow keys. The actual value is changed by using the up or down arrow. After changing the value, accept it by pressing the OK button. After accepting the value, use the Up or Down button to continue to the next block that you would like to modify
