Abbreviation / Term
Explanation
Magnetic tape
Magnetized tape with absolute coding, part of the position sensor system
Safe Box
Component of the overall system LIMAX Safe SG/SC, carries out the specified safety func-
tions and additional functions based on position information coming from LIMAX33
RED/LIMAX44 RED and on the state of additional inputs.
The Type SG or SC is determined by the Safe Box (Safe Box SG or Safe Box SC). The LI-
MAX33 RED/LIMAX44 RED is identical for LIMAX Safe SG and LIMAX Safe SC as well.
Sight glass
Window on top of Safe Box. LEDs can be seen through the sight glass. It is prohibited to
remove the sight glass.
Synonym: window
PIO cable
Power and I/O cable; contains wires for power supply, digital I/O and communication inter-
face to the control.
SCA cable
Safety circuit and actuators cable; contains wires for interfacing the door contact input (DCS)
and the safety actuators/relays.
Pre-commissioning mode
Operation mode of Safe Box. The shaft image is empty in pre-commissioning mode.
Teach mode
Operation mode of Safe Box. The shaft image is learned in teach mode
Adjustment mode
Operation mode of Safe Box. The floor positions can be adjusted in adjustment mode.
Normal mode
Normal operation mode
Temporary reference posi-
tions
Reference positions used to determine positions of final limit switches and inspection limit
switches in teach mode. Calculation of the positions of the final limit switches and inspection
limit switches in teach mode is based on the temporary reference position because the lowest
and highest floors are not known yet (in normal and adjustment mode, the lowest and high-
est floor are the basis for the calculation of the positions of the final limit switches and in-
spection limit switches).
The temporary reference positions can be learned in teach mode.
Technician
Suitably trained person entrusted with installation and commissioning of LIMAX Safe SG/SC
or suitably trained person entrusted with troubleshooting
Auditor
Person of a notified body responsible for initial inspection of a lift where LIMAX Safe SG/SC
is installed or responsible for the annual inspection
SC
Safety circuit
Rated speed
The rated (nominal) speed of the Safe Box and the elevator where the Safe Box is installed in
must fit. The rated speed is noted on the identification label. It cannot be changed.
Synonym: nominal speed
NOC
Non bridgeable relay contact
Relay contact to be wired in the safety circuit due to the instructions given in this manual.
OC
Bridgeable relay contact
Relay contact to be wired in the safety circuit doe to the instructions given in this manual
SGC
Relay contact to be wired:
To an external electromechanical actuator in case of LIMAX Safe SG
In the safety circuit in case of LIMAX Safe SC
SGC-FB
feedback contact from the switch served by the safety gear or the blocking device on the
speed governor, only used for LIMAX Safe SG
DCS
Door contact state
UPS
Uninterruptible power supply
