To use this type of connection reference should be made to the safety and installation instructions in the "SAFETY
MANUAL" (le: x08051ko-Safety User Manual-1_0r_IT and x08051ko-Safety User Manual-1_0r_EN on the CD-ROM

7.3.4 Connection diagram for emergency maneuver (for synchronous motor only).
Manovra di emergenza a “uomo presente”. La funzione ha lo scopo di permettere il movimento della cabina quando si
Emergency maneuver with operator present. This function allows the car to move when there is a power failure in order
to bring it to the closest oor by gravity.
• This maneuver can be performed only when the drive is in emergency mode, which the control card indicates with
the “Emergency Mode” digital input.
• Only for gearless applications (with synchronous motors).
• There must be a Brake Open digital input connected to a Brake Open button on the control panel that will enable
car movement. The input is congurable.
• When the button is pushed the inverter opens the brake contactor via the Brake Contactor Relay output.
• The operator then pushes the button to move the car.
• With parameter 11822 Em max speed (Emergency manual max. speed) you can set maximum car (or motor)
speed during this maneuver. The speed can be expressed in m/s (for the car) or in rpm (for the motor).
• If the car reaches the maximum allowed speed, the drive locks the brake for a time T congurable by parameter
11824 Brake lock time, disabling use of the button (which will not release the brake even if pushed).
• As soon as emergency manual maneuver is resumed, the display (both optional and built-in) automatically shows
the current car speed (or motor speed if set in rpm) and direction (Fwd or rev).
• This maneuver must be disabled in case of inspection.
The car will move (Brake Contactor = Open) only in the following conditions:
• Emergency Mode: ON (Contactor Closed)
• Brake Open: ON (Contactor Closed)
• Emergency Manual Vmax: < Vmax
• Contactor Lock Time = 0
• Parameter 11820 Brake Release Sel = Null (default)
