Overview & electrical data
The BR50L is the 32-bit mainboard of a Movilift manoeuvre controller. It runs calls, positioning, doors, the safety chain and drive control for hydraulic, geared and gearless lifts, up to 32 stops over the serial CAN bus.
- Supply: 12–24 VDC/AC ±10%
- Stabilized 12 VDC output for signalling
- Integrated 12 V battery charger
- Safety-chain inputs EXC / TOLT / CS at 24–110 VAC/DC
- Stores the last 100 diagnostic events
Programming keypad & modes
The board is set up from the on-board keypad and display, with three working modes:
- Programming — view and edit the configuration parameters through the tree menu.
- Maintenance — force movements and service functions during commissioning.
- Monitor — read live inputs, outputs, position and speed for diagnostics.
Hold ENTER for 3 seconds to clear a fault. Parameters are also reachable over the RS232 PC tool.
First start-up & shaft magnets
Before the first run the board learns the shaft. Position the slowdown and stop magnets, set the number of stops (parameter A2) and run the shaft Autolearning.
- Magnet layout differs for regular vs irregular inter-floor distances and for speeds below or above 1 m/s.
- The RS (up) and RD (down) re-levelling sensors and the IF / ICV stop sensors must be positioned correctly, or the board reports a positioning fault.
- Absolute positioning uses the BR-ENC board with a magnetic tape.
Doors
The BR50L drives automatic, semi-automatic and manual door operators, with independent open/close timing.
- Opening and closing times are set by parameters; parking behaviour keeps the doors held.
- Multiple accesses (single/double car entrance) are supported.
- Options include the retractable cam, door pre-opening and the CPP / APG limit monitoring used for EN 81-20/50 door-closed checks.
Plant & manoeuvre types
The board supports hydraulic and rope installations and the full Movilift manoeuvre set: universal, down-collective, full collective, simplex, and dispatch groups up to duplex / triplex / quadruplex, plus firefighters, hospital, rescue and Shabbat modes.
The manoeuvre and plant type are selected by parameter; up to 3 car and landing groups can be networked over the serial CAN bus.
EN 81-20/50 compliance
The BR50L implements the EN 81-20:2020 / EN 81-50:2020 safety functions, enabled by parameter C12.
- Reduced headroom / pit access detection (car-access and pit-access inputs) blocks movement and requires a keyed reset.
- Unintended Car Movement and door-monitoring contacts (CPP door-closed monitoring) are supervised.
- Absolute selector configuration with the BR-ENC board is described for compliant positioning.
