    Operation modes and Commissioning 11.1.2 Teach Mode 11.1.2.1 General In order to reach the normal mode (for normal lift operation), it is necessary to teach a valid floor table and/or reference positions using a commissioning process. This can only be done in teach mode. There are two kinds of teach procedures: manually and automatically.

    Initial and Annual Examination 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 ...

There must be no person in the shaft or on the car roof when carrying out this test.
  • Page 82 Initial and Annual Examination 15.7.6 Overspeed (Pre-Tripping) The auditor adjusts lift control/inverter in such a way that overspeed can be reached. He performs a travel, each in upwards and in downwards direction and with a speed just above the pre-tripping speed. Check: OC opens when pre-tripping speed is reached and the machine brake stops the lift.

    Functional Safety 17 Disturbances This chapter describes possible causes for disturbances and measures for their removal. In case of increased disturbances, please follow the measures for fault clearance ( 17.1). In case of disturbances that cannot be eliminated by following the advice and the fault clearance measures given here, please contact the manufactur- er (see second page).
