Bypassing the System (Engineering Maintenance Control)
To “BYPASS” the system you will disable the movement detection function, but if
the lift over speeds then the brakes will still 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. A LED indicator will also flash adjacent to the key switch.
If you are sure you need to bypass the movement detection then this is how it
should be done.
n
Check that there are no faults present and that there is no reason why the lift
cannot be put into service.
n
Check that there is power at the controller i.e. “Control Voltage” LED is
illuminated.
n
Insert the key into the reset/run/bypass switch.
n
Turn the key to the bypass position and leave it there, after a short time delay
a message will appear “ENGINEER BYPASS MODE”.
Warning the safety devices controlled by this controller are bypassed
while the key is in this position.
To get back to a normal running mode.
n
Return key to central RUN position.
