Access in the Pit
Access to the shaft is detected by opening a contact using the release key which activates the RSP fault (code 21),
preventing the elevator car from moving in normal operation (a run is only possible in ‘Inspection’ mode). Before
entering the shaft, wait for the traffic light to indicate the safe condition (green light).
After the end of the Inspection maneuver the personnel must:
• Remove the protections (in case of manual protections), Return the selector switch and any STOP buttons to
‘Normal’ and exit from the lift well.
• Close the landing doors (check the safety chain) and carry out the reset using one of the following methods:
– From the floor with three quick opening / closing of the reset key (optional).
– From the panel with three quick presses of button
– From the PlayPad with specific reset (RSP reset).
If controller detects an automatic contact reset (contact close before reset procedure) it gives again a Fault RSP (Cod
121) as a fault on coil’s reset circuit.
Characteristics of the auxiliary contact (BERNSTEIN type) only on the lowest floor:
• Bistable NC contact (does not open during normal door operation). connected to a dedicated input.
• 230 Vac reset coil
Optional reset key switches are electrically connected to BDU’s DOOR Contact input.
