Electric valve actuator LPU

rotaryanalog

100% protection and control of the LPU One circuit board only for LPU–S and LPU–D, analog and ON/OFF feedback, P-NET and hard wire voltage input controlled Being a P-NET slave the P-NET LPU is an independent unit to be controlled directly from e.g.a workstation. All LPUs can operate simultaneously with a suitable dimensioning of AC power supply Random delay restart of the LPU-S after an AC voltage drop to prevent all LPUs from starting at the same time, thus avoiding drawing high starting current in the system. From the P-NET indication can be given how the LPU was operated the last time; internal/external pushbuttons or from the P-NET From the P-NET change of Setpoint can be blocked ”AutoCorrection” option (the LPU retakes its position, and re-establishes pressure if it drops in open position on the LPU-S). This feature can be disabled when no P-NET communication is present, in order to allow emergency operation of the LPU if the P-NET fails Measurement of 24 VDC and VAC power suplies The unit is monitored even if the VAC supply falls out The presence of 24 VDC is displayed on the internal LEDs Prepared for future oil level gauging in the tank Good service/starting up facilities as the LPU
