Leveling magnets (7" north magnet): Bring the car even with the floor. Place the magnet centered
on the steel tape so that the DZO/DZO1 sensors are energized but the LU and LD sensors are not.
The use of two DZO sensors gives the redundancy for the door zone.

P1, P2, P3 = sensors located in the selector tape.
"North" magnets need to be used. The binary code is only validated when sensors are ON and the
elevator is centered to the floor (DZO = ON, DZO1 = ON, LU = OFF, LD = OFF). These
magnets are used to correct the elevator’s position, so it is important that the magnets be correctly
positioned.
WARNING
It is strongly recommended not to secure the magnets immediately to the steel tape. If a
mistake should happen in the positioning, it would still be easy to move the magnets on the
tape. Wait until you have made successful tests before gluing definitely the magnets to the
tape.Magnet installation with the IP8300-TP1 guide:
Automatisation JRT inc. has developed a guide permitting to quickly locate the door zone
magnets (DZO) and binary code magnets (P1 to P3).
