- Current values of the frequency converter
High friction values in the cab guidance (sliding guides) lead to "break away"
the cabin during take-off and increased current values while driving.
- Evaluation of the cabin movement by the accelerometer at the FKR
A continuous recording of the acceleration values (shocks) when accelerating the cabin can indicate a
worsening cab guidance.
If the limit value is exceeded, the message "Maintenance rail guidance" is output.
4. Temperature profile inside the control cabinet
An increased temperature profile in the interior of the control cabinet can have several causes.
A.) The ambient temperature in the vicinity of the control cabinet does not allow temperature
B.) The threshold temperature threshold of the control cabinet fan is set too high.
C.) The inlet filter mats of the cabinet filter are dirty and the filter passage is inhibited.
The temperature monitoring of the David central units allows for indirect temperature monitoring of the
control cabinet. The limit value is 45 degrees Celcius. As a monitoring period, the rush hour is set over
7 days. If the limit value is exceeded, the message "Maintenance control cabinet" is output.
5. Temperature profile of the frequency converter
An increased temperature profile in the frequency converter can have several causes.
A.) The ambient temperature around the frequency converter leaves no temperature valley to
B.) The inverter is dimensioned too small.
C.) The fins of the heat sink are dirty and the air passage is inhibited.
The heat sink temperature monitoring of the frequency converter allows for indirect temperature moni-
toring. The limit value is 70 degrees Celcius. As a monitoring period, the rush hour is set over 7 days.
If the limit value is exceeded, the message "Maintenance frequency inverter" is output.
6. Condition of the door contacts
In detail, this is about the shaft door-, cabin door-, and blocking agent contacts. If at least 1x of the
above door contact errors occur per day, with an observation period of 7 days, it is time to check the
door contacts, and probably also for maintenance. If the limit value is exceeded, the message "Mainte-
nance door contacts" is output.
A3 Output of the system status
Conclusions :
The calculated maintenance cycle may be extended or shortened based on the actual number of trips.
In addition, by occurrence of other events, the condition of the hoist can be degraded. The time to the
next maintenance can therefore be shortened.
The calculated maintenance interval will be displayed visibly in the maintenance menu.
In addition, the remaining time is displayed in days until the next maintenance date. If maintenance is
not carried out, the time will continue, but with a negative sign.
After maintenance, this counter is reset. It begins a new era counting down the days.
A4 Ways of visualization
1. HPG-60
In the fourth line of the HPG-display in standing mode the maintenance notification appears.
2. Maintenance display
The maintenance display in the control cabinet door / or inside the control cabinet has the following
structure:
