15.6 Verification of the Floor Table
The floor table as it is stored in LIMAX33 CP-00 must be verified. For example, this is possible by the following
procedure:
 Send the car from one floor to the other. Normally this will be done by car call. All floors stored in the
control have to be approached, Lift control should perform pre-opening of the doors approaching the
single floors. For pre-opening of the doors, door bridging must be enabled. Otherwise the open door-
circuit would cause an emergency stop. So if pre-opening of the doors works without emergency stop
it is proved that the floor number and the position of the floor, where the lift control wants to land the
car, is the same as in LIMAX33 CP-00: position and number of the target floor are communicated via
CANopen to LIMAX33 CP-00. The device will only close SR1 resp. SR2 if these information’s fit.
 Check if the car and landing thresholds are flush at each floor.
 Read the total number of floors stored in LIMAX33 CP-00 and compare it with the number of floors
stored in the lift control. This is done in order to ensure, that LIMAX33 CP-00 has not stored any addi-
tional floor at a position where actually is no floor.
Remark: this procedure is only possible if door bridging is performed. But that is no restriction because for a lift
without door bridging it is not necessary to learn the floor table.
Further Remark: if lift control does not support pre-opening it is also possible to carry out the check with the re-
levelling functionally: Load/unload the cabin at a floor and watch if the cabin relevels.
15.7 Check of Safety Functions
ATTENTION!
It obligates the user to ensure the safety for persons during check of the safety functions.
It is possible, to carry out all of the following tests without the presence of a person in the
car, on the car roof or in the pit.
It obligates to the notified body to judge, if it is necessary to carry out all of the following tests concerning the
safety functions annually or if it is sufficient to carry out some of them only at initial examination. The concrete
proceeding concerning the tests should be locked at as a proposal. The user and/or notified body may find
other ways to test the safety functions.
15.7.1 Final Limit Switches
The correct position of the final limit switches should be tested.
 The auditor calculates the position of the lower and upper final limit switches from the reference posi-
tions and the offsets of the final limit switches (refer also to  13.2.8).
 Now, the auditor takes the elevator to the top floor by car call. From here, he begins to move the cabin
slowly upwards (generally this will be done by using the recall panel) until a point just under the
top final limit switch.
 Then he switches off “recall” so that by measuring the voltage behind OC he can determine if the con-
tact is open. Here, the normal safety circuit voltage must exist (OC closed).
 The auditor now over travels the position of the upper final limit switch (by recall panel) by the shortest
possible distance and switches off recall.
 Now he checks the voltage behind OC. There must not be any voltage as OC must be open. The audi-
tor measures the voltage before OC as to crosscheck. The normal safety circuit voltage must exist.
The lower final limit switch can be tested by the corresponding procedure.
