If a lift fails to be sufficiently earthed or safety insulated, this will result in a substantial risk to the user. If immediate
earth bonding cannot be achieved then the lift must be taken out of service and the customer and supervisor is to
be informed on the future remedial work.
Where there is a discrepancy in voltage recordings, an investigation must be complete on probable cause.
Dependant on whether a solution can be found, it may be advised that the lift should be taken out of service. The
customer and supervisor should be informed of future remedial work.
If a new RCD or any other electrical component is required, record manufacturer, type number and inform
customer and supervisor immediately.
14.3 Safety gear and overspeed governor (Full safety activation required)
•
Required
standard
Before activating the safety gear, verify that they are set up correctly on the guides and there is a gap of 2.0mm
between the safety gear and the back of the guides (
Figure 3 - Safety gear setup
).
To achieve full safety gear activation, a link must be place between G2 to G2A. This will prevent the safety gear
monitor switch from cutting power to the lift.
At full speed, activation of the overspeed governor (
4.6 Overspeed governor tests, pg 5
) must bring the lift to an
immediate stop.
Once engaged, enter the lift and check behind the rear wall (
4.5 COP and rear wall removed, pg 5)
to see that both
sets of safety gear have engaged and that the lift car is secure.

Required
action
If for any reason the safety gear has not engaged, investigate possible cause. This may be due to a linkage error at
any point between the overspeed activation to the safety gears themselves. If only one of the safety gears are
engaged, ensure that these are set up correctly (
Figure 3 - Safety gear setup
). Whilst the safety gear activation
plate ‘A’ is lined up in the middle of the access holes, the safety gear roller ‘B’ should be set up in the centre of
each of the safety gears.
