Testing Methods
-
It should be established that adequate earthing of all metal work, such as
the car, landing doorframes, machine, controller and guides is provided. Pay attention to the landing locks, all electrical components in the shaft and car top should have secure and clean earth connections. Check landing pushes for earthing! -
The fuse protection of the safety circuit should be tested by either a purpose
made device or by measuring the resistance of the circuit and calculating
the short circuit current. The safety circuit should not be checked by
grounding its furthest point. It is recommended that to be consistent with
BS7671 Requirements for Electrical Installations: IET Wiring Regulations
and IET Guidance Note 3, this supplementary test should be called for at 5
yearly intervals unless it can be demonstrated that more frequent tests are
required or that less frequent tests will be adequate to ensure safety .
The earth continuity should not exceed 0.5Ω but check the OEM manual for
any relevant information regarding earth testing methods and acceptable
values. Lower values may be actually needed to ensure adequate protective
device disconnection time and higher values might be acceptable. -
Using calibrated multimeter, on OHMS check for resistance between all metal components, including distribution boards, isolators and controllers. Check terminations of trailing flexes within the controller and car top.
-
To blow the safety circuit fuse, using a shorting kit connect the top landing lock to the metal frame and ensure the fuse blows immediately.
A.1 Earth Continuity
-
State Method Of Test
-
Is the maximum continuity resistance to the earth 0.5Ω or less?
-
Has the fuses protection of the safety circuit been satisfactorily tested by either a purpose made device or by measuring the resistance of the circuit and calculating the short circuit current or test according to the OEM manual?
-
Please Explain
-
Does the result of the supplementary test(s) indicate further remedial work is necessary?
-
state your recommendation(s) for further action required
