2.3 ELECTRICAL CONNECTIONS
2.3.1 CONTROL PANEL REQUIREMENTS
The control panel must send to the power unit at least the following signals:
Mark
Signal/comand
Features
VS
Upward signal
10…40mA
12…48Vdc
V0
Speed : High
10…40mA
12…48Vdc
V1
Speed : Medium
10…40mA
12…48Vdc
V2
Speed : Inspection
10…40mA
12…48Vdc
D+
Downward signal
12…48Vdc, 60…180Vdc
D-
Downward negative pole
12…48Vdc, 60…180Vdc
The control panel must to receive and to understand correctly at least the following signals:
Mark
Signal/comand
Features
RDY
Ready
10mA…2A
RUN
Run
10mA…2A
UP*
Up
10mA…2A
OVL
Overload
10mA…2A
*Command used only to interface control panels that need different signals to start upward or doward 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 7.7.1
and 14.2.1.2 of the rule EN 81-2:2010. 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.
