LEV - Leveling relay output

LEV RELAY OUTPUT
Relay pulls up when lift leveling or re-leveling to floor
LR – Lock Relay input.
LR - Lock Relay input for LR Relay. High voltage input.
LR input controls LR relay. The LR n/o contacts are used in the safety circuit. (See page 2 of ECD circuit
diagrams)
LR and LRX inputs are wired in parallel. See also Inputs – Outputs LRX
LR – Lock Relay output
LR RELAY OUTPUT
Relay pulls up when LR input is on.
See also Inputs – Outputs LR
LRX – Aux LR input.
LRX/HV1 - Lock input for processor. High voltage input. Also used for monitoring 'BDL' (Lift Status).
LRX and LR inputs are wired in parallel. See also Inputs – Outputs LR
(See page 2 of ECD circuit diagrams)
LRX - Ram address R:44

M3 - Door Locks input

M3 - Lock input for processor. High voltage input
(See page 2 of ECD circuit diagrams)
M3 - Ram address R:46
MSD – Magnetic Switch Down input
MSD – Input pulls up on board relay MSD which is used in the masking/re-leveling circuit and inputs to tell the
lift to re-level and count.
Ensure the MSD slowing input is activated before the Bottom Slowing Limit (BSL) at the bottom floor.
Counting Operation (MSL=00) – When the lift is running down between floors it shall advance the position count
when a MSD input is received. The lift indicator outputs 1P to 6P shall change accordingly. The LCD position shall
remain the same until the lift passes through DZ. At floor level the MSD magnets must be within the DZ magnet
or a dual advance count may occur.
Re-leveling Operation – If the lift is stationary at a floor and MSD is off with DZ and MSU on then the lift shall re-
level up (LUP displayed on LCD) until MSD is switched on again. If the lift fails to re level to the floor after 3
consecutive, 10 second attempts, LEV will be displayed on the LCD. Lift shall no longer attempt to re level.
Note: LEV status does not take the lift out of service.
A re-level shall only occur approximately 3 seconds after a run or previous re-level whilst lift is on an appropriate
mode.
A re-level shall only occur if the doors are fully closed or fully open

MSU - Magnetic Switch Up input

MSU – Input pulls up on board relay MSU which is used in the masking/re-leveling circuit and inputs to tell the
lift to re-level and count.
Ensure the MSU slowing input is activated before the Top Slowing Limit (TSL) at the top floor.
Counting Operation (MSL=00) – When the lift is running up between floors it shall advance the position count when
a MSU input is received. The lift indicator outputs 1P to 6P shall change accordingly. The LCD position shall
