BSL - Bottom Slowing Limit input
Bottom floor position correction limit and forced slowdown limit for terminal floor
BSL input turns off as the lift approaches the bottom floor and activates the BSL limit switch
BSL input must remain off when lift is on the buffer
Ensure the MSD input turns on just before the Bottom Slowing Limit (BSL) at the bottom floor

BYPASS onboard switch
Onboard lock BYPASS rotary selector switch
The BYPASS switch can be used to bypass the electrical safety contacts of either (only one at a time) the;
Car Gate – Switch in position CGBP. Doors must be closed (DFC input off)
Locks 1 – Switch in position L1BP
Locks 2 – Switch in position L2BP
When switched to a bypass position, the lift shall automatically be placed on inspection.
See also Inputs – Outputs BPAV, CGBP relay, L1BP relay, L2BP relay
BPAV - Bypass Switch Audio Visual alert output
Darlington Output
BPAV output turns on when the Lock BYPASS switch on the board is switched to CGBP, L1BP or L2BP
Used for driving an external relay, to control an audible signal at the car and a flashing light under the car
CFS - Car Fire Service input
CFS turns on when the lift is keyed to CFS, unless inverted with MOD setting
"Car Fire Service" shall be shown on the LCD screen
CFS allows only one car call to be entered at a time and shall toggle to the most recent call
