5.2.2.3.2 Signal procedure at inspection
Note: When the inspection pushbutton is released, the
control
closes the
brake
and opens the
main
contactors
. The set value runs to 0 within 200 msec. The relay timing (ZB, ZS) of the VVVF controller
does not play any role
in this case.
Important note!
Before the drive contactors open, the controller enable (input GS, terminal 53) at the VVVF controller
must be withdrawn in order for the contactor to be de-energized. Do not use
the auxiliary contacts of
the drive contactors
for this, as these contacts are not always leading contacts. By connecting a
small relay approved by us
parallel to the drive contactors, a correct timing is guaranteed.
In the case of gearless application, an electronic auxiliary relay is to be used (for more
information, contact us).
5.2.2.3.3 Signal procedure for levelling operation
Note : When the flush landing level is reached, the
control
closes the
brake
and opens the
main
contactors
. The set value runs to 0 within 200 msec. The relay timing (ZB, ZS) of the VVVF controller
does not play any role
in this case.
Make sure to wait for at least 1 sec. between two levelling operations so that the ropes and the
mechanical equipment can settle. Otherwise it may happen that the elevator keeps levelling all the
time without coming to a rest.
