A2 Calculation of additional wear events
1. Conditions of the doors
The door guides and the door guide rails are subject to wear or contamination. With a high number of
door reversals associated with high contamination, maintenance may be required prematurely, prior to
reaching the door movement limit. Four criteria are available:
- Measuring the door running times and determining a tendency.
- door reversings
The door reversal leads to an increased wear of the door guide due to the forced change of direction
with high braking torque (inertia through the mass of the door leaf). A drive of the elevator car gener-
ally has 4 door movements without responding to the monitoring devices (light grid, vestibule monitor-
ing and closing force limiter). If 5 reversals occur on 10 elevator trips, this represents a limit value.
Formula for door movement OK: 1 drive <= 5 door movements observation period 30 days
- Door error
If at least one door error "door opening - time monitoring" occurs every day for an observation period
of 7 days, it is time for the door to be checked, and probably for maintenance.
- Evaluation of the door movement by the accelerometer at the FKR
A continuous recording of the acceleration values (shocks) during door-to-door operation can indicate
a deterioration in the door operation.
If the limit value is exceeded, the message "Maintenance doors" is output.
2. Condition of the suspension ropes
Suspension cables are subject to wear and reach the able-maturity after a number of trips x. The vari-
able "number of trips" is defined by the carrying ropes on the change of direction of travel. An uphill
journey from E to 1 and then from 1 to 2 is only possible to increase the count by 1. A subsequent
change of direction, i. a journey from 2 to E leads to an additional meter reading increase.
Program technically the entry of the life cycle level of the supporting rope is to be combined with a
code word query. Also, the date of the entry should be stored here. The meter itself is programmed as
a down counter. When reaching level "0", drive to the main access level and shut down the system.
For indirect hydraulic lifts, the lowest level must be approached! Output of the corresponding error
message.
A warning message "Maintenance ropes" must be issued 30 days before the discard condition is
reached.
3. Condition of the rail guide
We differentiate between roller and sliding guides for rail guides. The sliding guides are subdivided
into lubricated and unlubricated versions.
We have 2 criteria available:
