17.4 Overspeed 

lift 

 
Depending on when the lift was installed, an overspeed governor test switch may be present. This switch can be 
used to activate the overspeed governor remotely (from the test controls box within the upper landing controller) 
 
Access the upper landing controller and check the test controls box located near the bottom of the electrical 
enclosure. If there is a button marked ‘OSG test’ then the lift has been fitted with remote activation. 
 
To activate the overspeed governor using this button, simply drive the lift in the required direction and press and 
hold the ‘OSG test’ button until safety gear activates (Ensure that G1 – G1A has been linked out). 
 
If the lift is not fitted with the remote activation then follow the flow diagram below to activate the overspeed 
governor manually. 
 
 

 

When the user switches to 
full speed the overspeed 
governor will now simulate 
overspeed (over 0.2m/s) 

Access overspeed governor 
and switch rope to test 
grove. 

Access lift pit, lock off 
tension pulley and remove 
tension pulley packers. 

Re fit tension pulley and 
undo locking bolts (with 
packers removed).

pg 30).

 

When the user switches to full 
speed the overspeed 
governor will now simulate 
overspeed (over 0.25m/s)
