*1. When the LEV opening does not change, all output
phases are OFF.
2. When the output opens a phase and stays ON, the
motor will not run smoothly and will clack and
vibrate.
3. When the power source is turned on, a close valve
signal (2200 pulse) is sent to confirm the valve
position, ensuring a starting point of
A
.
4. When the valve is operating smoothly, there will be
no sound or vibrations from the LEV, when opera-
tion goes from point
E
to point
A
, the valve locks
and open phases create a considerable noise.
5. The noise emanates from the driver and can be
easily discerned by placing a screwdriver against it
and then placing your ear against the handle.
