SCB : This board is used in the inspection box and works as the car
controller board. It collects car calls and detector inputs in the car circuit. It
contains 5 programmable relay outputs and 12 programmable inputs, 16 call
registers, a battery charger for emergency power supply, and hardware for
other in-car lift functions. It also supports also announce system when AFM
(Announce Board) board is plugged.
SDB : It is the door bridging board plugged onto ALC.
SGD : It controls the activation of the coil on speed governor.
OUT : This board contains 4 programmable output relays
INPS : This board contains 4 programmable inputs.
CSI : This is CAN interface board in fault tolerant mode. It can be used in lift
group operations to communicate with other lifts, or to have a separate CAN
bus for landing panels.
CCI : This is CAN interface board in high speed mode. It can be used to have a
separate CAN bus for landing panels when landing panels have high speed
ETN : It is the ethernet interface board and is used to connect a PC to the
controller either in a local area network (LAN) or via the internet.
USN : USB interface board for local PC connections.
BLN : Bluetooth interface board for mobile devices.
IO : It has 8 call registers onboard. It is used to expand the number of call
registers on ALPK.
CAN-IO : This board communicates via CAN-BUS and serves as a call register.
One CAN-IO board has 16 call registers. It is used to expand the number of call
registers in car circuits above 16 floors or above 16 call registers in systems
where landing panels are not serial.
ALSK : This board is used in systems where landing panels are serial and
serves as a terminal board for programmable inputs and outputs in controller
and PTC. It contains xx programmable inputs.
ALPK : This board is used in systems where landing panels are parallel and
serves as call registers as well as a terminal board for programmable inputs
and outputs in controller and PTC. It contains xx programmable inputs.
SPB: This board serves as a controller in shaft pit. It communicates via
