VG OSG
Version 3
27
By-Passing The System
To “BYPASS” the system you will disable the unintended movement detection
function, but if the lift over speeds then the VG OSG willl be deployed.
This function is purely for testing and maintaining the lift. When in this mode a
sounder will beep every 30 seconds, to remind you that it cannot be left in this
mode.
If you are sure you need to bypass the movement detection then this is how it
should be done.
• Check that there are no faults present and that there is no reason why the lift
cannot be put into service.
• Check the “SET OK” LED is illuminated.
• Insert the key into the reset/run/bypass switch.
• Turn the key to the bypass position and leave it there, after a short time delay a
sounder will start emitting a beep.
• To return to normal operation – turn the key switch back to “RUN”.
Warning the safety devices controlled by this controller are bypassed
while the key is in this position.
Test Deployment Of
The VG OSG
To test deployment of the VG OSG follow the procedure below.
Note: this will also send an emergency stop signal to the main lift panel to
prevent the lift from moving. This stop signal can also be tested this way.
• Check that the “SET OK” LED is illuminated.
• Press the emergency stop button.
• The VG OSG magnet will be immediately de-energised and subsequently
deployed and clamp the ropes.
• Check that “SET OK” LED has been extinguished.
Warning the VG OSG will not reset until the stop button is reset.
