Door Closed parking management
5.7.1
P-49: Door Closed evacuation delay
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…99 = PSO active
The controller enables the PSO function, activating the PSO after the correspondent
delay in seconds
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.
The PSO function is required for EN81-20 applications, and it must be set to a value different form
zero (suggested 10s)
P-84: PSO position error
Parameter
Range
Default value
Description
P-84
[0 ; 20] mm
10mm
Maximum position error in opening direction, after
which the DCS is disabled and the controller gets out
of PSO mode
