OSSIBLE SOLUTION
Contacts SE1 and SE2 are both closed
WITH THE CAR PARKED AT FLOOR
Check the cables and connections to the contacts.
The wiring of the contacts to the control panel
has at least one interruption Restore continuity by replacing or repairing the line that
has interruptions.
The wiring of the contacts to the control panel
has no interruptions The control panel does not process correctly the signals
coming from contacts SE1 and SE2.
Identify the applicable solution in the manual of the

The SE2 switch is open with the car parked at floor
The VMP 2CH coil is powered
Verify why the control panel does not disconnect the
VMP 2CH coil power supply. Set the control panel
mode to disconnect the coil, when the car is parked at
floor.
The VMP 2CH cursor does not close properly Check that the ball closes and moves correctly inside its
