Improvements and expansions
› Adoption of the FST-2XT properties
MMI (man-machine interface - keyboard/display), processor structure, connectivity (USB, CAN Open LIFT,
Ethernet), NEW LIFT Guide (online conguration aid).
› Emergency mode monitor
The emergency mode monitor for emergency release for the lift attendant was integrated in the display of the
FST-2XTs.
› Auxiliary mode control (AUX)
Auxiliary mode control switches S21/S22 were grouped together in a single cam switch.
› Keypad
The keypad has the full functionality of the FST-2XT keypad.
› BUS connector plugs
Bus connectors X3, X5 and X6 were repositioned for easier use.
› Connectivity
Interface expansion to Ethernet, Mini USB, USB 2.0, CAN Open LIFT
› Operating elements of the lift attendant panel
»The operating elements in the lift attendant panel area were, in part, implemented as pressure mats.
»Adjacent to the pushbuttons, LEDs have been added as button acknowledgement.
»LED illuminated ->button pressed, function active
»LED off - > button not pressed, function not active
»Function button “F1” (currently without function) and the selection buttons for controlling external
safety devices for protected area safeguarding for shaft head and shaft pit were added to the previous
operating elements (brake release button A/B, anti creep device, evacuation switch, brake test key
switch and shaft door reset button).
› Improved visual signalling.
»The LEDs, IN/OUT (BUS trafc), safety circuit inputs and 24VDC power supply for shaft bus (X5/6) are
now located directly on the front panel.
