Initial and Annual Examination

15.7.6
Overspeed (Pre-Tripping)
The auditor adjusts
lift control/inverter in such a way that overspeed can be reached. He performs a travel,
each in upwards and in downwards direction and with a speed just above the pre-tripping speed.
Check: OC opens when pre-tripping speed is reached and the machine brake stops the lift.
15.7.7
Overspeed (Final Tripping)
Overspeed (final tripping) can be performed in the corresponding sub mode of the test mode.
The procedure is done is already described in the corresponding section
The test in downwards direction is always performed, in upwards direction only if feature setting “trip direction”
is “both”.
15.7.8
Overspeed Inspection
The auditor performs an inspection travel with inspection travel speed higher than the pre-tripping speed in-
spection of the LIMAX33 CP-00.
Check: OC opens when “inspection pre-tripping speed” is reached and the machine brake stops the lift.
Remark: if it is not possible to adjust inspection speed in lift control to a value big enough, so that
Safety function “overspeed inspection” trips leave the lift in normal operation (neither in EN81-21-state, nor in
inspection state) and simulate the EN81-21-state to LIMAX33 CP-00 by disconnecting the EN81-21-signal from
the corresponding input of LIMAX33 CP-00.
Test of “overspeed inspection (final tripping)” will be more difficult in most cases because the machine brake
(tripped due to “overspeed inspection (pre-tripping)” may decelerate the cabin before “inspection final -tripping
speed” is reached,
If it is nevertheless possible to test the safety function “overspeed inspection (final tripping)” in a safe way, check:
eSGC opens when “inspection final-tripping speed” is reached and the safety gear stops the lift.
15.7.9
Door Bridging
Door bridging has been already checked in combination with the verification of the floor table.
15.7.10
UCM
The car is on a floor, door circuit is bridged. Now start a travel without disabling the door bridging.
UCM must trip latest as soon as the door zone is left.
Remark: Starting a travel without disabling the door bridging is normally only possible if this is implemented as a
special (test-) feature in the lift control. If this is not the case, the car may be moved by recall control while door
bridging is enabled. Alternatively, the car may be moved by hand wheel.
15.7.11
Working Platform
The auditor enables safety for “working platform” by opening the corresponding (external) contact. He checks
that all available actuators (OC, eSGC, SRS1 and SR2) are open.
