VG OSG
Version 3
19
Connections to the Main Lift Control Panel must be carried out carefully to ensure
that the correct function of the signals is produced.
The control box input signals are 12V DC 100mA they require a dry / volt free relay
contact normally open and energised when the Car and Landing doors are closed.
The operation of these switches is essential to enable the VG OSG to operate safely,
i.e. if a cable is broken or the lift over speeds the VG OSG will be FAIL SAFE. i.e. any
problems, the VG OSG will activate.
The connection from the Main Lift Panel such as Alert signal and emergency stop
must be 230 Volts maximum and must not exceed 5 amps. The control box provides
dry / volt free relay contacts for your signals.
Please also see electrical drawings supplied with this manual for further information.
SAFETY NOTE:
DO NOT TAMPER WITH THE CONTROL BOX
If it does not allow the VG OSG to reset then there is still a problem with the lift!
Rectify the problem and the controller will allow a reset.
Do not leave the lift to run in engineer “bypass mode”, this is purely a function
to allow you to carry out maintenance on the lift without triggering uncontrolled
movement. You will have circumvented part of the safety circuit.
