F 3
Example:
Main principles for electric troubleshooting in stop circuit
– control voltage 110V/50Hz or 127V/60Hz.
1. Switch on the main ON/OFF switch and close the gate/doors.
2. Check that the final limit switch is in the ”ON” position.
3. Obtain the circuit diagrams and lists which are kept in the cabinet used for this purpose in the hoist car.
4. Then test with a voltmeter or test lamp between the zero terminal and the terminals in the electric cabinet as
described below:
Test Result Conclusion
Between the zero terminal and last no reaction fault located in stopping circuit
terminal in stopping circuit.
Terminal 322 according to diagram
in example above.
Then test each terminal in the stopping circuit systematically, beginning from the transformer.
between zero terminal and terminal 301 reaction the circuit is intact to and incl. terminal 301
between zero terminal and terminal 304 reaction the circuit is intact to and incl. terminal 304
between zero terminal and terminal 314 reaction the circuit is intact to and incl. terminal 314
between zero terminal and terminal 316 reaction the circuit is intact to and incl. terminal 316
between zero terminal and terminal 318 reaction the circuit is intact to and incl. terminal 318
between zero terminal and terminal 320 no reaction the circuit is not intact to and incl. terminal 320
Reason
The switch may have been actuated because of:
– a foreign object between the switch and the cam.
– unbalanced counterweight wire ropes.
– a loosened wire rope.
Action
Check the mechanical function and connection of the
switch. Adjust the counterweight wire ropes, if necessary.
The terminal numbers listed
below apply to this diagram
only. The procedure for testing
other electric equipment with
other terminal numbers is
carried out in a corresponding
manner as described below.
Probable fault location: element C11. The
diagram indicates that C11 is a slack rope
switch, located on the car roof.
