5.7 Door Closed parking management
5.7.1 PC25: Door Closed Parking mode
This parameter permits to enable the “Parking with Skate Opened” (PSO) function.
Parameter value Notes
00 = PSO not active
(default value) The controller, during parking with door closed, keeps ALWAYS the skate closed,
applying a reduced parking torque to the motor enough to keep the closed position.
01 = PSO active The controller enables the PSO function
The door closed parking phase generates, mainly for long parking period during lift unused time, a power
consumption and a continuous torque applied to the motor to keep the skate closed also if the car is
parking at the floor.
For this reason the PSO function has been developed. To manage this option, it is necessary that MLC:
1. Removes DCC command when car is parking at the floor without calls
2. Not activate error or alarms, in case the safety chain gets open during the parking phase at floor
after PSO activation (the open skate opens the locks)
3. Activate DCC command at least 2s before the car starts to move for a call
If all the previous conditions are satisfied, it is possible to exploit all the advantages given by the PSO
function.
In the table below are reported all the parameters that configure the PSO management. These parameters
are accessible ONLY by external handset device with the following path: Main Menu
