A two position valve control is to be programmed.

• The valve can be driven totally opened or totally closed. It is not possible to stop in an intermediate position.
• The valve is driven by an electric motor that is controlled by contactors in Electric Center (EC)
• EC Contactors are controlled by PLC outputs "Open Control" and "Close Control"
• The operator opens or closes the valve using a turning switch in the Control Panel
• Close (K, Kiinni) -> PLC activates and keeps activated the output called "Close Control" until a Closed Limit Switch is activated -> Electric motor is stopped
• Open (A, Auki) -> PLC activates and keeps activated the output called "Open Control" until a Open Limit Switch is activated -> Electric motor is stopped
• Indicator Lamp "Moving" (LIIKKUU) is blinked while valve is moving
