2.3ELECTRICAL CONNECTIONS
2.3.1 CONTROL PANEL REQUIREMENTS
The control panel must be able to send at least the following signals to the power unit:
The control panel must to receive and to understand correctly at least the following signals:
* Command used only to interface control panels with different signals to start upward or downward
travels
Outputs RDY, RUN and UP
- report to control panel about the system state,
- determine when the control panel must start or stop the motor /pump
WARNING
The control panel, when receive a FAULT signal from the NGV-A3 card (RUN and RDY output),
should not send commando to the valve and/or the motor/pump
In FAULT condition the motor/pump group should NOT be active
WARNING
To detect the unintended movement of the car the system use the circuit required by paragraph 5.8.3
of the rule EN 81-50 and 5.6.7 of the rule EN 81-20. This circuit, if it detects a movement of the car,
with doors not closed, outside the unlocking zone, prevents the control panel to send any command
to the valve. The system restore should be performed only by an authorized and properly trained
person.
• Distance of setting: ± 200 mm
• Maximum time for the intervention of the circuit 270 ms
For other data or signals sequence see next paragraphs of this manual
Car speed in the instant of
intervention of the braking device ≤
1,3 m/s
Response time of the device that
detects the unintended movement
of the car ≤ 270 ms
Response time of the braking
devices ≤ 200 ms
Time from start of the unintended
movement to the instant in which
the car sensor leaves the doors
area (dimension = ± 200 mm)
Stopping time of the car ≤ 500 ms
Point in which the car stops
between 0 and 8 the maximum
distance travelled is ≤ 100 cm
