2. Mechanical

 

2.2 Base tower section

 Check the section for cracks and destructions. See pictures below.
1. No bended cross bars.
2. No cracks at connection positions.
3. No incorrect welding seam.
2.3 Tower sections Same criteria like at 2.1 Base tower section.
2.9 Start-up cams for limit switches. Check the position of the cams.
2.10 Buffer, buffer receptacle.. Check that the buffers are free of damages.

3. Electrical System

3.1  Insulation of the cables. Check the cable for cuts and / or damages:
Check all cables that were mounted during the assembly on site.
Check the cables for optical cuts and / or damages. (You can also find the overview in the wiring diagram).
3.2    Insulation. Measurement of the insulation resistance of different circuits for this measurement the electronic components are to be disconnected.
>0.5 MΩ for protection class 1.
3.3    Earth conductor resistance. Verification of the connection between the earth terminal of the machine room and the different parts to be made live accidentally.
<0.3 Ω for protection class 1.
3.10 -Emergency telephone. Precondition for this check: telephone signal cable has to be connected to working telephone system
4.1 Motor brake. Test Run: Drive in automatic mode to any landing or to base enclosure. The car has to stop maximum 10mm higher or lower than level.
4.2 Safety gear Dynamic drop test of safety gear:
1. Put weights into the cabin. First drop test will be executed with 125% of maximum payload.
2. Execute the drop test (please refer Maintenance Manual section 9.6.1 ).
3. Reset the safety gear (please refer Maintenance Manual section 9.6.2).
4. The drop test must be carried out all 6 months. (please refer Maintenance Manual section 9.2).
5. The safety gear must be replaced all 3 years. (please refer Maintenance Manual section 9.2).
4.3 Trailing cable. Trailing cable (flat cable) have to be checked for cuts:
Trailing cable without cut:
4.4 Overload protection. Overload switching at 110% of payload.
Put weight into the cabin. The overload alarm has to get activated at more than 110% of payload.
Take a look at the red lamp at the control unit ( 4 ). Overload is activated if red lamp is on.
4.5 Tower Sections Check the transition of the tower sections by using the rack gauge.
4.6 Limit switches (roof).

Information:

If the hoist is working in automatic mode (normal operation) then the hoist starts from the reference limit switch and the levels get reached by using the encoder.
If the hoist is working with the installation control on the car top then the hoist is working in inching operation and stops at the limit switch down or up.
Limit switch down:
Drive down the hoist with the control of the car roof.
The car stops on the bottom cam and do not drive down ahead.
Limit switch up:
Drive up the hoist with the control of the car roof. The car stops on the top cam and do not drive up ahead.
Reference limit switch: Drive car in auto mode down to base enclosure. Car stops on correct height and reference limit switch is working.
Emergency end: Drive to limit switch end or push the limit switch. The hoist has to stop.
For information: The emergency limit switch is part of the emergency line.
4.7 Proximity switches. The inductive switches release the safety relay for the door locking.
Proximity switch test.
Drive to the base enclosure or any level.
The sensors are working if the door gets released.
4.8 Landing door.

Check landing door not to be opened during elevator operation.
Check if landing door is to be opened by triangular key when car is in front of any landing.
Open landing door ➔ elevator does not accept driving command.
4.9 Car door.

Check car door not to be opened during elevator operation.
Check if car door is to be opened by triangular key when car is in front of any landing.
Open car door ➔ elevator does not accept driving command
