The PVENP device is a unit which can be mounted between the input device (joystick or controller) and an analogue PVE*. The

function of the device is to de-energize the supply to the PVE when the set-point is inside a defined range around neutral. See

figure below.

The power to the PVE will switch off when the demand signal is inside a range of ± 4% of neutral. A delay is associated with the

power off function and no delay on the power-on function. (See response time page 1)

PVE is disconnected. The input signal Us should not be disconnected.

We recommend that the neutral power off function is checked regularly. The power to the PVE must switch off when the input

signal Us is in neutral. Check that the LED light turns off which indicates that the PVE will be disconnected. The input signal Us

Please be aware that when the PVE is disconnected the fault monitoring is disconnected as well.
