Design and Functions
- 46 -
There is a separate operating manual for LIMAX33 RED/LIMAX44 RED and the magnetic tape which has to be
observed:
The LIMAX33 RED/LIMAX44 RED provides safe position information to the safe box via RS485 interface.
The Safe Box performs the actual functionality. This consists of:
1.
The safety functions according to chapter
2.
Additional non-safety-relevant functions:
Door zone signalling in case of power failure
Transmission of position and velocity to the control via CANopen
Figure 19: Components of the Safe Box
At the back side of the box there is the female M12 connector to connect the position sensor LIMAX33
RED/LIMAX44 RED, on the front site there are the cable outlets for
power and I/O
(PIO) and
safety circuit and
actuators
(SCA), and the teach button.
On top of the safe box there is a window behind which the user can identify five LEDs used for signalizing.
The two cables either have open wire ends or are connected to a 25-pole connector.

Guidelines for the Implementation in the Control
There is a close connection between LIMAX Safe SG/SC and the lift control, which is part of the safety concept.
Without this connection, LIMAX Safe SG/SC does not work. Communication between control and LIMAX Safe
SG/SC is carried out via a CAN bus and follows the protocol as specified in
PIO cable
