Readjusting the floor levels
WARNING!
The readjustment of the floor levels has to be done only by a properly trained technician.
The technician’s training is the customer’s responsibility.
It may be necessary to adjust the floor level of single floor levels (e.g. due to structural changes in the building
construction). LIMAX Safe SG/SC allows the adjustment of individual floors up to ± 50 mm from the previous
position. For this purpose, the technician changes the LIMAX Safe SG/SC from normal mode (
10.4.3) to the
adjustment mode.
The control must be able to process the user requests and pass them on to LIMAX Safe
SG/SC by CAN. See
/CO_SPECS/ object 2140h for further information.
In adjustment mode, any number of floors can be adjusted as follows
9.
Enter adjustment mode (
9.2 Operation modes of the Safe Box) by pressing the teach button for 2 s
(
10.
The cabin is moved to the flush position. In general, the position in the control is adjusted first, so that
the cabin is in a flush position after moving to the floor level (by car call).
11.
The technician signals to the lift control that the respective floor is to be adjusted in LIMAX Safe SG/SC;
the floor number is fed in with the signal (numbering from bottom to top starting with 1 for the lowest
floor).The door must be open and the cabin must be at a standstill.
The control then forwards this signal to LIMAX Safe SG/SC via CAN bus. If the current position of the
cabin is not more than 50 mm away from the old floor position still stored in LIMAX Safe SG/SC, the
adjustment is accepted and the current position is adopted as the floor level position. If the difference is
more than 50 mm, the adjustment is not accepted and the floor level position remains unchanged.
12.
Repeat steps 9 to 11 for every floor.
13.
When all the floors are adjusted, the technician leaves adjustment mode by pressing the teach button
for 2 seconds (
NOTE!
Adjustment mode is left automatically by the Safe Box if the cabin was in standstill for at
least 15 minutes.
The adjustment mode is indicated by an acoustic buzzer signal in the form of a beep every 2 seconds.
When LIMAX Safe SG/SC detects a system error (
11.5) in adjustment mode, the adjustment mode is left im-
mediately and the floor image prior to entering the adjustment mode is loaded again. The adjustments which
were already made are lost.

Triggering the safety functions
When an elevator fault, which is covered by the safety functions described in chapter
8, occurs, the contact
specified for the respective safety function is opened:
OC for bridgeable opening of the safety circuit
NOC for non-bridgeable opening of the safety circuit
SGC dependent of the type:
- for SC: additional non-bridgeable opening of the safety circuit
- for SG: direct or indirect action of the blocking device of the safety gear (to prevent car movement)
